I am sorry, but we don’t cover the automotive audio market.

I would recommend googling a site that does cover that industry.

I agree completely with Bob and Paul…especially in the room acoustics and subwoofer multiples options.  I would also caution Shawn about not just the “.1” but also the “10”!  Obviously room size will play an important part in the required number of speakers/drivers, but remember that the relatively new supported discrete format is 7.1 (Blu-Ray Disc, discontinued HD DVD) and only 5.1 is available discretely via other HD sources.  A good surround processor will be able to “simulate” the 7.1 or 7.2 from a 5.1 or 7.1 source…but anything beyond that is truly an engineer’s idea encoded into a simulation mode or possibly encoded into a soundtrack and then decoded with DPL IIz.  But again, these additional channels are not discrete and vary widely based on which manufacturer has created them.  More isn’t always better.  Quality over quantity is sometimes key.  Just a thought…

Shawn’s question, which the post doesn’t reflect focused on the Denon’ Audyssey room acoustics processing options.

The Audyssey system included in Denon’s flagship receiver should handle the room’s acoustics without a problem and the many other features in the Denon should also be more than enough for Shawn to build a good home theater and multiroom audio system.

I also want to point out whether the person who posted a response about subwoofers realized it or not, that adding multiple subwoofers is a good way to deal with some low-frequency issues in a home theater.

By adding multiples of two (2, 4, 6) installers and homeowners can sometimes mechanically through subwoofer placement neutralize some standing wave issues to create smooth and deeper bass within a room.

One good option that’s just now available is BG Radia’s BGX system. This system was designed by Laurie Fincham of THX and it features four woofer modules that can be mounted within a wall or left freestanding. It’s powered by a single rack mountable controller that incorporates amplification for the modules.

The BGX system is quite impressive with its smoothness and ability to play music as well as movies without sounding sloppy.

If that’s not an option multiple subs from the companies mentioned (Klipsch, Paradigm, Sunfire, Def Tech)will work well too.

@Shawn:  I think you may want to rethink the .1 aspect of your system and use 2 or even 4 subwoofers depending on the size of your room, and sonic tastes.

I always find that my favorite part of my home theater is that ‘punch in the guts’ feeling from a great subwoofer set up.  For my room, I found one sub wasn’t cutting it.  I originally had a Klispch reference 10 inch sub for bass duties, but wanted more boom.  I replaced the Klipsch with a Sunfire HRS-12, which was a definate improvement, but still wanted more.  I ended up with a second HRS-12, which was such a dramatic improvement, I cursed all the years I only had one subwoofer!

I wanted to add 2 more subs, but the furniture placement and wife didn’t allow for it.  The compromise we made was to invest in a butt-kicker system for the seating, which is also a very cheap way to get a large amount of tactile feedback into a room without a massive dollar expenditure on subwoofers.

Finally, if you are limited to one sub, which it doesn’t sound that you are… go BIG! Paradigms new reference sub, or Definative Technologies Trinity sub are pricy, about $3k each, but should provide enough bass energy for almost anyone.
