I can't seem to come to any resolution by myself, so I would appreciate input from you guys on the pros and cons of each alternative. I need an amp(s) to power my planned subwoofer setup. This will be an infinite baffle design, with 4 AV15's per side. I'd like to keep it stereo, so that rules out a single amp driving a mono load. For now, I'll plan on using both voice coils of each driver. The low Qts should be just to my liking, but if I need to alter the Q I'll use a linkwitz transform (may use one anyway to flatten response). I'd also like to figure around 250W per driver as a target to shoot for. Any choice will have to be either standard shelf or rack-mount chassis types. No plate amps. That leaves the following options: (1) Single stereo amplifier, stereo mode, 4 AV15's per channel, either 4 ohm or 1 ohm per channel. (2) Two stereo amplifiers, one per side, 2 AV15's per channel, either 2 ohm or 8 ohm per channel. (3) Two four channel amplifiers, one per side, 1 AV15 per channel, either 4 ohm or 1 ohm per channel. For some reason, I have the urge to use a separate amplifier per side. Not sure why... perhaps because I have an addiction to large numbers of separate components?! Perhaps it's the peace of mind of having a separate power supply for each channel, and the ability to use two electrical circuits to ensure adequate juice to the amps. My concern though is that a stereo amp per side would either be running into an 8 ohm load per channel (not as efficient), or a 2 ohm load per channel (higher distortion figures). Would I notice an increase in distortion due to 2 ohm vs. 4 ohm loading of a typical prosound amp? So... any thoughts you guys have on the pros and cons of each alternative, please do share them. Also, any specific amp recommendations for your preferred alternative would be great. From a quick look at some choices, it seems the two amplifier, stereo 2 ohm per channel alternative would be roughly the same price as a single large amplfier (due to the increase power output in 2 ohm vs. 4 ohm, thus two smaller amps could be used). I'm suffering from overanalyzingitis. Help!
