Silver Member Username: BelieveIllinois Post Number: 147 Registered: Jun-05 | i would like to make a list of high power class a/b amps for sub use i plan on using this list to make my next purchase.. i think it will also give members of the forum a split amp recommendation.. one list for sound quality and the other list for efficiency after finding out what kind of electrical system they keep or are willing to upgrade and the sound quality of their subs we can select from either list i am looking for a class a/b amp to run a 12w7 i have come across these amps DAB1800X http://www.digitalaudioinc.com Hifonics XX Chaos http://www.ikesound.com/product-product_id/4371 those are the only two that i can find that give 700+ watts @ 3ohm _________________________________________________ this list needs to be at least 200watts @4ohm to fit into the high power category im gonna start the list and i would appreciate if anybody adds to it zapco 750.2 http://www.zapco.com/ LANZARMXA242 http://www.audioclubhouse.com/proddetail.php?prod=MXA242 LANZAR MXA252 http://www.caraudiodeals.com/product_info.php?products_id=565 HIFONICS TXi5006 http://www.audioclubhouse.com/proddetail.php?prod=TXI5006 HIFONICS Zeus ZXi6406 http://www.etronics.com/product.asp?dp=E2F2C2D222E6421253B3D363C3B357E3736373731 34313&stk_code=hifzxi6406&svbname=32&CA=Y HIFONICS Zeus ZXi1006 http://www.sonicelectronix.com/viewitem.php?id=6517 HIFONICS TXi7506 http://cnet.bizrate.com/caramplifiers/pid415455452/compareprices__nwylf--.html DUB Mag Audio DUB2502 http://cgi.ebay.com/DUB-MAG-AUDIO-DUB2502-Amplifier-2-Channel-Class-A-B-NEW_W0QQ itemZ110000917006QQihZ001QQcategoryZ18796QQrdZ1QQcmdZViewItem |

Silver Member Username: BelieveIllinois Post Number: 148 Registered: Jun-05 | that dls amp puts me at about 650watts at 3ohm and i seen that crunch amp when i was making the list but i didnt consider it worthy its not a bad list.. but i find it hard to believe theres only 2 mainstream amps that support 700watts+ at 3ohm |

Silver Member Username: JuliobSanto DomingoDominican Re... Post Number: 848 Registered: Dec-05 | why do you have lanzar on the list? |
|
Silver Member Username: BelieveIllinois Post Number: 149 Registered: Jun-05 | because its 2400 watts @ 4ohm subtract 900 watts because the internals are filed as cheap that leaves it with 1500 watts with a probability of being very clean and that probability is high with the most sensitive test equipment when i was finding amps for the list i put it here cause its a popular amp.. that doesnt mean ppl buy them but i see them often |

I can guarantee you arent super-human with your hearing.. So, if your ears are in fact human, you will not hear the difference in the same amount of clean power, given to a sub, by a class AB, or a class D amplifier. There are no disadvantages to using a class D amplifier to power a subwoofer, over a class AB. |

Gold Member Username: FandimReno, Nevada United State... Post Number: 1237 Registered: Jun-05 | oh BTW - that dub mag audio amp you have, is only 550 watts bridged... And they're over-rated already.. Also - they are the single most lousy line of amplifiers in existance, I believe. I've used a couple of these, and literally...Words cannot begin to describe how truely horrible they are. http://www.epinions.com/content_234916122244 |

Silver Member Username: BelieveIllinois Post Number: 150 Registered: Jun-05 | class d amps have a buffer reading the output and sending it back in the chain unless the map is psychic.. its not quality its no different then playing first person shooters if you render ahead your actually slowing down to add reliability.. basically you are a couple frames slower then the next person if your upgrading for quality reasons you should know why your old quality sucks play a 10hz note on a woofer and understand that each peak to peak is a crest if the woofer slows down at all during the back to back motion it now becomes distortion because the wave has gone from playing strict 10hz to 10ish kinda 9hz the feedback system isnt perfect and the woofer will slow down and speed up during the 10hz wave its communication and communication takes time i dont want a box of metal with two dip wads that have to talk everything out when i can let the hyperactive solo do it without question and lets say they have all the feedback kinks worked out to 1 nano second peak to peak @ 10hz with a 1 nano second correction time equals 1 billion possibilities of error 10hz means the speaker moves back and forth 10 times in 1 second 1 second equals 1 billion nanoseconds that means every second there is a chance of 1 billion errors now play 50hz.. thats 50 moves in 1 second with 1 billion chances for error BUT the higher the sub plays the smaller the peak to peak gets as the excursion grows smaller the distortion is greater because the room for error is less for example.. if your only movin millimeter by millimeter and you trip (amp error) thats cutting that millimeter in half and the speaker only moves half as much as it should that is also the same thing as an amp clipping because if the amp has a 1 nanosecond error and only moves half a millimeter your sub just stopped.. instead of traveling that extra 1/2 millimeter the sub just sits still creating heat that will blow the sub coil quick why dont my subs voice coil fry then? well thats because the amp uses pulse technology that slowly pushes the speaker in and out while the music plays on top of it so when the amp trips and that 1/2 millimeter comes up the sub doesnt stand still because its slowly moving in and out watch some sub videos when they pulse.. they call it a camera trick but it shows the evil so i guess the only ppl who got tricked are the ones who dont understand |

Gold Member Username: Alias747MN Post Number: 1094 Registered: Apr-05 | LOL, don't even bother Seth, I already argued with him about this and he wouldn't listen. It's worthless. Although you are completely right, there is no way to tell D from A/B when powering a sub. If you could tell then somebody would be getting paid $10,000 from Richard Clark. And it hasn't happend yet. So if he wants to waste his money with buying a VERY expensive and inefficient amp for negligible results, by all means let him. |

Gold Member Username: FandimReno, Nevada United State... Post Number: 1238 Registered: Jun-05 | Believe, this is in response to the crapfest you wrote earlier. Sure, one nano second talk science behind it all you want. So lets talk something else about the human biology we could relate this to. The human eye see's about what? It's much debated, but the common answer is between 30-64ish, but to avoid debate on THIS subject, lets even say it was 100. If your eye can see 100 frames per second, what good would it do, to watch a movie with 10,000 frames per second? You would notice no difference watching it at normal play speed, between 10,000 frames, and 100 frames. The human ear can be related to this - in the fact that it has limits to it's abilities. At the frequencies a subwoofer plays, your ear is not going to even come close to hearing the difference in the output of a class A/B amplifier, and a class D amplifier. Comparing it to my previous example (just a comparison, the physics behind it, are of course, different) a class D amp would be like watching that movie at 100 frames per second, whereas a class A/B amp would be like watching that movie at 1,000 frames per second. You're not going to see/hear the difference between these two. So you can talk all your little nano second errors billions of possibilities half millimeter not-too-far gibberish all you'd like. I just put this into simple terms that maybe you'll be able to understand. |

Silver Member Username: BelieveIllinois Post Number: 153 Registered: Jun-05 | slow a sub down to 5hz and put this in slow motion as the sub slowly moves out a class d amp will push the cone at a variable speed a class a/b amp will push out with a constant speed that means a class d amp will slur and stutter musical notes before a class a/b amp will why would you consciously buy 100 frames per second over 1,000? all day long ppl in this forum are telling others to buy something better |

Gold Member Username: Alias747MN Post Number: 1096 Registered: Apr-05 | OMG dude, I told you this before. Would you just shut up about it? Who the hell listens to a 5 hz tone anyway? Find your own damn amp if you aren't going to listen to us. Your ranting makes no sense and it is only making inexperienced ones in this forum dumber. So for everyones sake, cease talking. |

Silver Member Username: JuliobSanto DomingoDominican Re... Post Number: 878 Registered: Dec-05 | believe is dumb, he's buying something that he won't listen, just because he's dumb. Why do you want to see a movie with 1000 frames if you're only going to see 100. Get 100 and don't be stupid! |

Silver Member Username: N2audioLawrence, Ks USA Post Number: 894 Registered: Mar-04 | Believe - there seem to be many, MANY trees blocking your view of the forest. But - FWIW - if you look at Lanzar's manuals on line you'll see that the mxa242 is 400w rms bridged, and the 252 is 600. However, you should probably still keep them both on your short list since they'll OBVIOUSLY sound better than a nice 1000w class D amp. |

Silver Member Username: BelieveIllinois Post Number: 155 Registered: Jun-05 | well.. film isnt perfect and there are still times when the original film that the movie was recorded on has flaws im sure youve seen at the movie theatre when theres spots all over the picture that flash like an old vinyl record with all the crackles and pop watching all those imperfections at 100 frames per second would be much more noticable then if you were watching them pass by at 1,000 frames per second with 1,000 fps special effects would have better frame by frame detail and i do believe we just upgraded optical mice to laser same scenario.. the grid is much larger with a laser mouse then with an optical mouse your hand might not need all the extra grid but its more precise when you need it what about more megapixel in a camera.. how many megapixels can one percieve? should they stop once they get there? hell no! then they can start workin on 3D photos on flat paper with all the extra pixels they have what about those pictures within a picture? maybe your eyes are fooled at 5,000 and no longer see individual pics but 50,000 would be like going from 16 bit color to 32 bit color youll get farther with locked knees rather then trembling ones (reverting back to my variable/constant push statement) |
