shogen Posted May 9, 2014 Report Share Posted May 9, 2014 basically... are you planning on using better components(speakers) at some point and going active? Cuz I'm lost at the spending of extra money to run a component set... If you are getting the 80prs for features there are many out there for less.... Clarion cz702 comes to mind... But I love the 80prs just wouldn't buy mezzos unless this is just a starting point... Not down playing them or anything just wondering .... maybe me asking this will open up the discussion of your end goals w/ your system ... that is all Not sure what you are asking shogen. @ krakin - I see how the signal differs between the two. Thanks for the picture it makes my brain happy So now, is the difference going to be audible? I am running about 1000w rms substage if that makes a difference Pioneer Premier P880PRS ll Front Stage: US Acoustics 4060 - Random speakers currently ll Sub Stage: Crescendo BC3500D - 15" Xcon sealed @ 3.28 cubes ll Electrical: - Kinetik HC1800(front) NEW***DieHard P-2(rear) beaker- I know this sounds like a lot of anime bullshit, but it is true.

Mike Gibbens Matthew Posted May 9, 2014 Author Report Share Posted May 9, 2014 It is a starting point of sorts I suppose. I currently have a crescendo S1500.1 on my Treo subs. I was planning on running as much Crescendo gear as possible. Unfortunately this hobby is addictive and I will be constantly upgrading I am sure. Are the Mezzo's not up to the task of being a very high quality good sounding component set? 07 KIA Spectra 320a Singer Alt Odyssey Extreme batteries 2 12" Phantom sounds (4.6 cu. net @ 32) - soon to be 2 Atomic ELE 2 Rockford Fosgate T2500bd-CP Zapco Z150.2 Front comps soon to be Hertz HSK Pioneer 80prs Second skin deadener throughout Link to comment Share on other sites More sharing options...
Krakin Posted May 9, 2014 Report Share Posted May 9, 2014 As for the sub stage I would venture to say that it won't be noticeable to the inexperienced ear and being at the low frequencies the switching becomes much less noticeable. If you are worried about the front stage components I would not go with a Class-D design, even though recent designs have improved quality a lot. To quote the conclusion of my second link. In conclusion, Class-D amplifiers have evolved a lot since they were first invented, achieving levels of performance similar to conventional amplifiers, and even better in some aspects, like an inherent low output impedance that allows effortless bass. All this, with the great advantage of high efficiency. Of course, only if they are properly designed. Krakin's Home Dipole Project http://www.stevemeadedesigns.com/board/topic/186153-krakins-dipole-project-new-reciever-in-rockford-science/#entry2772370 Krakin, are you some sort of mad scientist? I would have replied earlier, but I was measuring the output of my amp with a yardstick . . . What you hear is not the air pressure variation in itself but what has drawn your attention in the two streams of superimposed air pressure variations at your eardrums An acoustic event has dimensions of Time, Tone, Loudness and Space Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears, thus no formula can achieve a definite effect for every listener.

shogen Posted May 9, 2014 Report Share Posted May 9, 2014 so far ... I love my zed mikros on my front stage... will be installing my horns and second mikro soon .... see how it sounds then but w/ the 80prs I'm quite happy... no sub BTW .... obviously missing it right now ... lol As for the sub stage I would venture to say that it won't be noticeable to the inexperienced ear and being at the low frequencies the switching becomes much less noticeable.

hispls Posted May 9, 2014 Report Share Posted May 9, 2014 I can't vouch for the Crescendo full range class D, but the technology certainly exists to make a class D that will sound every bit as good as A/B. If you stick to the high end class D amps I'm confident you won't be disappointed. Link to comment Share on other sites More sharing options...

gckless Posted May 9, 2014 Report Share Posted May 9, 2014 I'll put my class D front stage amp against most people's class A/B amp and win. Class of amplifier isn't everything. That being said, A/B will typically sound better up to a certain price point. Will most people notice it? Probably not, chances are pretty good there are problems elsewhere in your install and class of amp isn't the problem. And like has been said, unless you plan on upgrading your components, you're probably not going to notice a difference. "Clipping" is the biggest forum boner now. It's like witchcraft... it automatically explains just about everything people don't understand.

BoomZoom808 Posted May 9, 2014 Report Share Posted May 9, 2014 IMO unless you have robot ears you will not hear a big difference. My sources are personal comparison of an Alpine PDX F4 vs a Boston GT-2200. The GT has the slight edge but that's because its 200 watts per channel which is double the power at the same ohm load and it also takes up twice the real estate to install. 2010 Mazda 3s 2.5L Pioneer DEH-X9600BHS Knu OFC 1/0 SS Platinum AGM / XS Power XP750 Alpine PDX F-4 / Morel Maximo 5 + Coax 5 IA 10.1 / SSA XCON 12 Link to comment Share on other sites More sharing options...
Mike Gibbens Matthew Posted May 10, 2014 Author Report Share Posted May 10, 2014 Im going for it. Ill check out the Crescendo class D amp. Ill have a good amp to compare it to also. My wife is getting a Zapco Z150.2 and a Z150.4. Class AB SQ amps.

Kyblack76 Posted May 10, 2014 Report Share Posted May 10, 2014 Did NOT read a post. TRUE sq, is NOT CLASS D.... no way, no how..... DGAF TDamore and Ray dont poke fun at class D for no reason........
