Class D for SQ mid amp?

Cheap amps sound like crap in general when trying to go for SQ

Tube amps bleh. I never understood the desire to willingly add high level distortion coleration to music.. To each there own though :)

High Quality tube amps do not add distortion...., how about you listen to a McIntosh stereo amplifier for home, which is a vacuum tube amp, and see if you hear any distortion, I dare you.

LOL @ Distortion

You might want to read up on the different designs ;)

not many cars can get me to pluggin my ears but this one.......damn. I mean the first minute is ok but that thing just really starts digging deeper and deeper in your earhole till you cant stand it no more. Seems like it does it with relative ease....16 12's on 8 amps.........gotta love it. :)

He does have a point if this was 15-20 years ago ;) Some tube drivers were as much as 20% .Of course class D amps were just an idea and class a/b were a buck a watt.

Tube amps will sound different then transistor. Some people like it, others not so much. Of course some people also like horn cars, and others not so much

That amp may be a big exception to the rule ... beings that amp cost around 800.00 plus

not many people can pay for 4 of them just for a 2 way active setup ...

For 800 $ you get one channel of the 8 channels of a SB 8 in maximum upgrade.

Honnestly, you are correct there ... although I've only heard one or two in action, they sounded amazing ...

I edited my previous post on this ...

as for the horn cars ... The few I heard back in the day sounded GREAT !!! but required ALOT of EQ ... but driver positioning and installation tactics were phenominal !!!

Kind od wish I could hear a Sound Quality horn car on more of "today's" electronics ...

This is something that I came across while doing a research paper.

http://www.crutchfield.com/S-brvtW7DAPtC/learn/learningcenter/car/amplifiers_glossary.html

An amplifier is classified according to its circuit design and the way its output stages are powered. Although some may assume that for every portion of the input signal there is corresponding 100% output from the amplifier, power dissipation (in the form of heat) and distortion of the audio signal are two key factors in determining the efficiency and fidelity of an amplifier. Each class has its own performance characteristics and advantages.

  • Class A amplifiers are desirable for the high quality of their sound, but, because of the configuration of its transistors, a pure class A amplifier is inefficient and runs very hot. This is because even when there is no audio signal, the output transistors always have current running through them. The current flowing through the output transistors (with no audio signal) causes the amp to heat up unnecessarily, and "waste" input energy. Most car amplifiers that boast "Class A" circuitry are really Class A/Class AB hybrids.
  • The output transistors of Class B amplifiers actually turn off for half of every signal cycle. This improves efficiency and saves energy, but introduces distortion during the switching periods.
  • By far the most common car amp design, Class AB amplifiers also allow current to run through the output transistors when there is no audio signal, but at a much lower level. A class AB amplifier runs cooler, and therefore, more efficiently than a class A, with low distortion and high reliability.
  • Class D amplifiers use output transistors as switches to control power distribution — the transistors rapidly switch on and off at least twice during every signal cycle. Class D amps boast higher efficiency, produce less heat, and draw less current than traditional Class AB designs. Class D amplifiers produce higher distortion than AB designs due to the high-speed switching on and off of the transistors, but this distortion occurs at high frequencies that are typically removed by a low-pass filter.
