I'm going to be replacing my 4 Polks with something better in a few months and I need to know what to look for.

I don't want to spend more than $200 a pair and they need to be coaxial because I don't have a spot for the tweeters. I will also be buying a 4 channel amp as well so please take that into consideration.

I've looked around and I like the JL Audio TR and VR series, and the Infinity Kappa 62.7 were OK. I've heard excellent things about MB Quart, but I haven't heard any of them around here.

What other brands should I look at? Are Memphis or Pioneer Audio worth looking at? Any ideas you can give would be appreciated.

4 speakers? You'd be better off just buying 1 good set and powering them properly because it will sound better.

As far as the tweeter goes, I am in the same boat as you. I don't want to cut up my doors again. I was looking at CDT braxials because they are a component set but the tweeter is mounted to the mid. Check them out at http://www.cdtaudio.com/braxialadvantages.htm

I have heard nothing but great reviews for CDT and they can be had for about $200. Slap a good powering amp on em and they will sing better then 4 speakers.

Just my thoughts.

If that doesn't suit you, I would stick with the JL or maybe some Alpines as Infinity is not that great.

Well, there's two speakers up front and two on the rear deck. Those are what I'll be replacing.

Has anyone heard anything good about the Pioneer Premiers at all? And what would be a good 4 channel amp?

Take a look at this http://www.glasswolf.net/caraudio/rearfill.html

Rear speakers are not really ideal, they only detract from the front soundstage.

The Pioneers aren't anything special. If you want good coaxials the JL will probably be your best bet.

yes i think the premier has some best sq like the ts-c701prs components, but heres what i have from kenwoods emotional series which is only out in japan, the sound produces lifelike sound as if you have band playing in front of you, detail and clarity is great, this is the K- eso1 seriesUpload

So even with my front speakers buried in the floor boards, things will sound better with a nice pair of coax up front and pair of midrange drivers in back?

get a good set of components for the front. if you really want something in the rear deck then get some simple 2way coax's.

get an amp tho, it will sound like night and day!

a lot of people on here will say just scratch the rear speakers. if you want to go that route, you can get some good quality comps and a 2channel amp for them. your never hear the speakers in the rear anyway. all the sound should be coming infront of you

A set of speakers with 150w in front of you is better than 2 sets with 75w surrounding you.

As for the Pioneers, he was talking about coaxials, and Pioneers coaxials aren't anything special.

I would like to thank all of you for the help. I do have one other question:

Would you consider CDT Speakers (namely the CL-EX6 or CL-61EV) equivalent to the Focal speakers close to the same type or better? I know they want a bit more power than them, but do they give a better sound?

there are some CDT dealers. Exige and AlterAudio. they would be more than qualified to answer any questions you have about those specific speakers. they might even know something in the same price range that will be better. i suggest making a new thread like "CDT SPEAKERS" or something that will catch their eye.

just my .02

The bit that isn't sinking into my head is why are component speakers from the same line (for instance JL Audio TR component vs. TR coaxial) are better than the coax. Besides the fact that you can take them out later and put them into another car that has separate tweeters and such, how is it are they better?

Is it the crossover bit? And if so, how are components better than coaxial with crossovers (like the JL XR series)?

Because in a coaxial, the tweeter is mounted essentially IN the cone of the midrange. It's a major disturbance speaker as a whole. It messes up the response of the speaker. Secondly, by mounting the tweeter at your feet or where ever the speaker is mounted...and having no ability to aim it (15 degrees of adjustment does not count)....the tweeter location flat out sucks....typically it's firing straight into the passenger footwell, nowhere near your ears. Being able to aim the tweeter to create the best soundstage for your acoustic environment is what makes a component set great.

The crossover issue mentioned with regards to the JL XR is a non-issue if the crossovers are the same.

With regards to convertible vs. coaxial and CDT....I have a different recommendation..braxial. Braxial allows for a bracket that the tweeter mounts. What this does is it takes the tweeter out of the midrange's cone....significantly helping the midrange's sound. Beyond that, it allows for better aiming abilities than a convertible or coaxial. If your car is like mine, a small coupe with speaker mounting location close to the mid-section of the door... then the tweeter mounted near the midrange is not a bad thing at all...it's one of the more optimal point available for MY specific acoustic environment.

Everyone's acoustic environments in their car is different though. Component with separate tweeter location typically offers the best response. Braxial is typically a convenience thing. I'm one of the lucky ones where it combines convenience and optimal response.

It should be noted that its not optimal to aim the tweeters right at your ears. A statement in my previous post read differently than I intended for it to.

So in your opinion, how much better do the CL-61CV series sound over the CL-6EX?

And do both of those pale in comparison to the Braxial or the HD-63?

pesonally i wouldnt even look at the CL line..seems like you have the funds to step it up to the EF line...that's what i would do if i were you.

HD>EF>CL

I cant even remember if we discussed proper soundstage or not yet but rear speakers can color the sound in a very negative way. I typically suggest forgoing the rear speakers and spending twice as much on the fronts. You'll hear the effects of that in a much more positive way.

With the braxial stuff...it's not a matter of depth. If you're worried about depth, you simply have to look at the mounting depth of the midrange driver...that's what your mounting depth is gonna be.

This is what the braxial setup looks like if you've never seen it before:

It's not so much the mounting depth I'm worried about on the Braxials, it's getting the speaker cover back over it when it's installed. All of the installed pictures I've seen of the Braxials are all uncovered.

When I say the CDTs are one of the best out there at their price, thats from a LOT of first hand experience, as I run a set in my own vehicle.

I also praise other brands that I've heard and was impressed by, like rainbow, diamond, focal, etc.



I will say this: I've never heard that specific set. But judging from everything else I've seen from kenwood, I'm skeptical of them.

i normally don't join in company bashings...but to let truth be told..kenwood's gotta prove themselves first. they make some decent head units...some of their high end excelon stuff was really nice. but their amps have constantly overheated on me (had a 9102 a while back along with an 840-somethin...4 channel is all i remember). the reason that no one hear is takin you seriously about this is simply because kenwood hasn't put out a serious SQ speaker or sub before. we're not sayin they can't...they just simply havent. considering that the speakers you mention of are available only in japan or somethin...whatever you mentioned earlier...it just makes it harder to grasp.

i'm happy to give kenwood a chance...its just that up to this point they havent proven themselves. if they can build a solid product, then awesome. i'd appreciate some more mainstream companies building decent stuff. seems like alpine and pioneer are the only 2 doin it these days (JL of course also). we simply need to get a first hand listen to the k-eso 1's. it's very possible that they could be as good as you say..but we just need to hear them. there's no offense meant to you in any way at all.

And marching further into "The Retards Guide to Car Audio," what is the difference between the EF-63 (What is the EF series anyway? I didn't see it on the CDT website), the HD-63, and the HD-63Z (or ES-630 since it's around the same price)?

Since we're also in my general idiots guide, how do the upper JL Audio offerings like the XR-650CXi and the C5-650X sound in comparison to the lower TR series, the CDT speakers above, and even the two Focal types of coax?

k this has the possibility of being a really long answer so ill try to make it as brief as possible.

EF is a division of the CL series....regardless of the notation, it really is worthy of its own level though. it's a significant step up over the CL series.

it's denoted as CL-EF on the CDT website (by the way...all who find the CDT website absolutely worthless, feel free to send a short email to info@cdtaudio.com ...we've (as in some of the dealers) have been trying to get the site revamped for a while but its gonna take customer input as well...it surely needs a thorough makeover)

So EF is mid-line CDT, HD is upper line, ES is top line.

I really wish woofersetc.com didn't exist at times because they throw so many questions into customers heads about what's current. half the stuff on their site is NOT current product...the ES-630 being one of those. The ES-62i is the current top of the line CDT set, and was an upgrade over the ES-620.

Every step up is gonna provide better sound all around. Better midbass, better midrange, better treble.

I can't compare the JL line for you as I haven't personally done a comparison of their whole line. Lastly, difference between Focal and CDT has been established so I won't rehash that. I will not compare coaxial to component. They're on two separate levels. The difference between the two has also already been detailed in the Focal vs. CDT thread.

Well, I did send in an email to CDT and got a reply back from John at CDT support saying that they're planning to start a redesign in February. At least it's something. He was also nice enough to run down some things about the speaker line as well. Is it worth it in my case if I buy an HD-63 to upgrade to the SX1000 crossover as well or is that just a waste of money?

Are there any recommended amplifiers to use with the HD line? Can they get by with just 150 watts RMS or do they really need the 180 watts to sound right?

The HD and ES lines are two things first of all. HD is high end CDT, ES is competition grade and has a 10-year warranty.

560i is enough for most people, SX1000 is gonna give you a lot of extra controls if you're into fine-tuning and such.

HD can get by with 150w. Typically I recommend around 200 or so for them though. The most economical but sturdy 2-channel amp I've found for that power is the Elemental Designs Nine.2x. There's many higher end amps available as well.
Alpine's PDX 2.150 typically births at 175x2...that's a real nice amp also. On the budget side, RF's P550.2 is available for $200 from crutchfield right now. That'll do around 175x2 or a lil more also.

It's almost always less expensive to buy the braxial setup all at once than to buy an HD-62 set and then get the braxial mount.

Glad to hear about the website...man I couldn't even get an answer about timing for a re-design when I asked a week or two ago. Looks like they're finally getting the point.

I'm sure it's been said already (I didn't read through the entire post) but by all means take all your money and invest in one set of great comps for the front. Front stage is all that matters. Running speakers in the rear takes away from the realism. When you watch a concert the musicians are up front right? Thats where the music should come from.

If it were my system I would buy one great set for the front stage, remove the rear stage completely, and still invest in a 4 channel amp. Then as money permits I would buy another set of the same comps and kick panels for the front floor boards. Then you will have one awesome and powerful front stage.

You'll need a good sub to keep up...

I have a pair of Memphis Audio MSYNC8 (8" components with the tweeter being adaptable for component or coax mounting). On paper, it looked like a great solution for my situation but it is a mid-fi product at best. It has decent sound but not audiophile stuff. It's cheaper than Focal 6.5" coax but the performance comes up way short in SQ.

it'll be the same mounting depth as the EF-6 driver. Unfortunately, I can't access the CDT site right now. My server is not connecting with CDT's site, my site, or CNN for some very strange reason....yet i can still post here lol. off the top of my head, i think it's 2.5". as soon as my internet is back up all the way, i'll look through and get full specs for you. are you looking for the basic EF-6 driver or an EF-6CF (carbon fiber)?

in the future, if you're looking for any info from the CDT site...just PM me or email me. i'll dig it up and get back to you ASAP. i've tried to memorize where everything is on that mess of a website so i should be able to find it pretty quick.

And pretty soon they'll be making speakers for Aston Martin as well.

So how do the CDT coaxial speakers sound? I noticed the slim fit ones are EF speakers. Are they still better than the CL series? Also, are two amped 6.5" midrange drivers a good substitute for no going with a shallow mount subwoofer (like an 8")?

Yep Aston Martin shortly also.

Coaxials are coaxials. That's as simple as I can put out. They're a matter of convenience. Sure they sound fine....but from any company...the only reason they exist is simply for convenience. By all means, components are recommended.

If you're not using a subwoofer, my recommendation would be to grab a pair of M6+'s or ES-06+'s and throw 150w to them, and use those as your 6.5" driver of a component set. If you haven't seen a pair before, this is what they look like (notice the large surround, just like a sub): [img]http://cdtaudio.com/cdt_new_0107/M6+-white.gif[/img]

CDT's description from the site is as follows:
"HD-M6+ and ES-06+ are the most exceptional drivers in the mid-size range.
This speaker delivers subwoofer bass and reference quality midrange at the same time. The ES-06+ is an amazing work of art in speaker design. The dome and cone vibrations are combined with rare precision to get synergetic results. Most subwoofers have a midrange performance that can color the sound even considering the low crossovers often used. The ES-06+ can be used as a small pure sub or as a mid/woofer with top results. The trade off is that the sensitivity must be slightly lower as is characteristic of subwoofers in general due to the heavy construction of the moving parts that simply take more power to move and which can also move further. Again the trade-off is against dynamics but here one speaker replaces two and in a small car can deliver."

I was reading around eBay and found this at the authorized CDT Store:

Is that actually a production model and does that come in a 6.5? Also, do you lose any sound quality in the EF NEO instead of going with the full sized EF?

EF Neo simply changes to a neodymium motor to shave mounting depth. Sound quality is the same. It's available in a 6.5. I really don't know what's up with that auction....CDT doesn't make a TW-26 tweeter so that's a load of BS right there. And to put the 480 into terms.....I don't sell it unless people request it....standard crossover is the 560 in my sets.

I think we were talking about the HD and ES lines a short while ago? I probably missed EF coming back up... But anyways..if you're still interested in the HD and ES stuff, you'll be interested to know theres a new 6.5" mid coming out shortly. It uses an inverted neo motor. What I'm talking about is below. It might be of more interest to you.

It was the EF and HD lines. ES is out of my budget and I don't want to get into a situation where my sound system is worth more than my car.

Are those going to be offered in a braxial or just as a midwoofer? What kind of RMS load do they need? And is there a braxial model with the EF Neos since my doors and my rears are kind of thin?

Understandable, just wanted to get on the same page as you. This will be just a driver, no braxial.....not really physically possible to make it braxial. If braxial is a must, HD is the way to go. If braxial AND slim is a must, EF is the way to go.

EF Neo is not standard with braxial. It can be modded to use braxial (just drill two tiny holes in the frame)....but its not standard as braxial

Would a pair of ES-6NEO be a good replacement for a subwoofer, or is it just a better idea to get a sub? Does CDT make a shallow mount sub? And do you know what the MSRP for the ES-6NEO drivers are?

I would get a some nice mids, and a sub. Mid woofers just don't cut it. There are tons of slim subs out there that are cheap.

Even a 10" with 300-400 watts would work nice.

No they're not a replacement for a sub. CDT has not listed MSRP yet, but I will find out very shortly.

No shallow-mount subs, but the subs that CDT has do not require much airspace at all. The HD-8 takes as little as .2 cubic ft.....it's like building a box just so that it follows the edges of the sub's basket...it's tiny. http://cdtaudio.com/longexcursionsubs.htm

Mounting depth on the HD-8 is less than 4.5". For a 12, it needs .7 cu ft and mounting depth is just over 6".

What is the benefit (other than weight savings) to the Carbon Fiber subwoofer over the comparable model? Also, MMXExpress has a version of the EF-63 braxial that's made from Carbon Fiber:

You talkin about the EF-8 Carbon Fiber sub? If so, that's not a current product that CDT makes anymore. Some stores might still carry it, but it's not up to date. The subs out right now are strictly the EF, HD, & ES Gold lines. None of those are carbon fiber.

In the EF component sets though...CF has a much larger effect than just being more lightweight. It's a better all around driver, it's a highly upgraded model over the standard EF-6 driver. Better midbass and midrange, plus it can get louder. If you're looking for an EF set, aim for the EF-61CFi/25 set....EF-6CF mids, 560i crossover, TW-25 tweeter.

It seems now it's down to budget since I had to repair my car after this last ice storm over here. In case I need to go the cheap route, how are the Alpine Type X Reference Comps? They come with a tweeter bridge so I can use them. Are they better or worse than the CDT coax?

Alpine Type X is a high end component set. Coax's are coax's as we've discussed. Between the two, go with Alpine. How cheap are you getting the Type X's?

I've found the Type X Reference for around $160-180. The Type X Pros are double that and out of my budget (and it doesn't come with a tweeter bridge).

Are the Type X as power hungry as the Type Rs? I've like the sound of the Rs but they needed quite a bit of power to get that way. Is it the same with the Type X or is 70 watt RMS just fine?

Between speakers, sub, and amp, it'll probably cash in at $600 before labor, and I'm still not sure if I'm going to buy a sub or not. Since I'm also going to sound dampen my doors, that adds a bit more as well.

How do the Type X Reference compare to the EF-63 Braxial?

It also looks like if I go with a CDT Braxial, it'll probably have to be a 5.25" with a mounting ring in order for it to fit.

How are the midbass response from the various CDT speakers mentioned in this thread (assuming the doors are deadened)? Their frequency response looks a little high in the 70 hz range.

they're both very decent. HD>EF...as you would expect. M6 is king for midbass though (among regular drivers - M6+ is the dictator but it needs a sealed enclosure, or one hell of a well-deadened door).

Would they be better or worse than the Alpine Type X you've heard?
