Hi Fi Car Audio

I'm also interested in the 9200. Can you change the phase of the sub just a little bit. I had a local car audio guy tell me that one of the problems with my system is that as the bass comes to the front of the car the bass form my mid bass 8's and the little bit that is eveident in my 4's are clashing just a little bit out of phase causing my bass to seem disconnected and out of the sound stage. I drive a Mercedes 190e and cannot put my sub in the cabin (Boston Accoustic Competitor C110, it's a 10 with a passive radiator) I do however have the 8's (Boston Accoustic rs-8) On the floor behind the driver and passenger firing at the celling. do think that this unit will help solve some of these problems, or do you know of other units that have sub woofer delay or advance reseptively through delaying everything else. thank you

Carbear, I think that this unit would do what you want. By changing the amount of delay of the sub, it would have the same effect as changing the phase. You are still modifying the time correlation of the drivers.

Thy will be done.... Nakamichi makes a reference standard type of head unit called the TP-1200 there is a (special shop) model which has no tone controls and upgraded parts. The board is suspened and isolated from vibration and the head unit is merely a control unit. The actual pre-amp is mounted in the rear near the amps the head unit controls a servo activated real volume potentiometer. McIntosh clearly makes the best car amps and a great sounding parametric equalizer as well as a transparent 5 way electronic crossover network with memory presets. Use a Wadia D/A converter As for speakers I intend to use parts from teh new Red Rose R3 speakers. Or perhaps the Proac speakers. Screw the "car speakers" they suck. Use Dynaudio and Focal drivers and Vifa Midbass drivers. Also I hear the new Eminent Technolgy planar diaphram car drivers 20kz-400hz are nice. Stuff it all into a Mercedes E class sedan with the subs working in an free air infinite baffle arrangement over teh rear deck. The front stage drivers must be mounted in kick panels. Don't try to use a wide car like the older s-class because the listeners will be too off center. consider a sheet of VB3 lead septum damping sheet over the transmission tunnel and Dynamat under the roof liner and on the doors. spray Rockford fosgate noise killer in the door ares you can not dynamat. Cars are quiet now (good ones at least) They are small enough to pressurize easily to have convincing bass, luxury cars have enough sound deadening and less over all decay times. Finally the electronics are good enough save for teh d/a converters for cars. Do it in a Mercedes, at least the car will last. Putting a high performance system in a car like a Kia is like putting your home stereo in a room made out of cardboard. (I'm sure this will piss off some people... but it is true- flex is bad in a door panel.
