james when did i say 2 15 l7s? ive owned cvrs before.
chauncey, even though u say you know everything and never listen to anyone elses opinions, here this:
right now my re sx 15 is a lot louder than my 2 12 cvrs i had with 800rms, and my sx is on 500rms. putting the 2 cvrs next to that on the same 800rms, i dont think will be louder than tripling the power on the sx, by doing 1500rms to it.
it might be pretty close, but you dont have to shut me down just because of cone area, or piston area.
last time i talked to marshall white, he said that when he was hittin in the 148s with the sx he sold me, that he got beat before by 0.1db by 4 15s. im sure the 15s werent great, but they probablay werent too bad.
"hauncey, even though u say you know everything and never listen to anyone elses opinions, here this"
when did i say this??? never once did i say i knew everything...no one knows everything..
u do relize that kicker amp is doing more then 500rms.. and that audioburn didnt do 800rms...also the sx is a more efficient driver then the cvr...
it takes 1000rms for the sx to reach full excursion...so anything extra wouldnt really matter..the 4 12's would out do 1 15..if both in a great install..even with 1500rms..
im not shutting u down..i thought we where better then that...but dont say stuff like that..
a single SX can take 4 12 CVRs given the CVRs are not ported.. how do i know? Because I've competed agaisnt that exact setup.. you do realize how much room you will need to port 4 15"s? ... Hope you have a sh!t load of room otherwise you'd be stuck sealed and then it would be nearly a toss up between the two.. other than that both ported the CVRs
mother of god and baby jesus. when will you people understand that is 95% INSTALL and 5% equipment......
i could make a CVR louder than an SX with the same wattage applied to both. GUARANTEED, just slap the SX in a sealed box, and slam the CVR in a 4th order bandpass and CREAM all over the SX's face.....stop with this incessant b.s. arguing....
chauncey you do shut down my posts all the time. why havent u been on aim..i havent talked to you forever. none the less with comparing, the sx 15 i got is loud as hell! i just ordered a massive audio 1500rms amp last night, and tongith i hope to order 0 guage eko from knu, and a 150a fuse and fuse holder. the hope i dont lose any current with the 150a though
muddy i think when people are comparing subs like we were, they just assume that each sub is in around the best box it could be in ported, with same tuning or w/e.
chauncey what do you mean anything above 1000rms on the sx wouldnt do a lot? chad lee said running 1000rms on his, then upgrading to 1700rms was a huge difference, he said it made it insane in his car.
ive seen a guy with 4 15 cvrs whip my 4 16ov.2s like a little bittch...he was hitting 156-157 with a 14cuft wall tuned to 44hz with 200 and something inches of port area. i heard he just upgraded to CVXs, i kinda wanna see what hes hitting with those now.
lets use some common since here people...1 18...4 15s...1 18...4 15...hmm?
i tried to tell em jake.lol anybody know who said this famous phrase??? 4 15s got me beatin up the block...cup full of lean hell yea them boys taxin,.thats how it is when u gotta roll candy???
well it would probably sound like pooop 1st off because it wasnt made for sq. i would guess 145-148 with normal music. impossible to tell saying all songs are different.
ill be the first to admit its almost impossible to drive if your music is at 145-150dB. i metered my car at what my "normal" volume was on the HU and it was 139.5dB which is pretty loud.
dont expect anywhere near 155dB out of that system tho. he had to make alot of different boxes and change alot of things to get it perfect. i think 148-150dB with 4 15 CVRs would be a good goal to set that is somewhat reachable.
also when he hit those high numbers he was putting over 4000rms to the subs. (crossfire vr4000d)
(4)15CVRs in a proper install vs the (1)Q18 in its... CVRs will win. Cant deny its a decent way of getting the most bang for the $$$. Heck I dont feel like scrolling back throught the bickering to see if an actual amp or amount of power was listed for this... but Im sure a single Q18 wont take whatever power your using for (4)15CVRs. BTL18 might be a different story though...
trade offs. the Q will have better SQ, I'm pretty sure. The CVRs (4) will be louder simply due to more cone area and more total cummulative excursion. (they'll move more air) however you'll also need a ton more power to get the most out of those four fifteens, and you'll need a lot more airspace, too.
this could all be figured out by looking at the excursion of each sub, and figuring total surface cone area with some simple geometry. It's not rocket surgery.
