I'm wondering if that's not simply a result of people setting maximum output at frequencies in the 40-50 region and not having the amplifier headroom for the demands of any frequency below that. So many variables involved with that aspect of performance.

    I plan to annihilate the 12hz to 24hz region and filter around 45hz to hand off to the front stage, so probably no use of SSF. I'm hoping things will just be excursion-limited (four 4 12's moving 3inches on subsonics) with obvious demands for high current delivery from the amplifier, but with enough high voltage delivery as it begins to get into the 30's and 40's. I do this all the time with single driver setups, just looking to scale it up.

    Dammit, I was hoping to go the value route with watts. I just want to find something that delivers numbers, doesn't break, and sounds good. So I should probably reset my budget for $300-$400, at least?
    Personal experience combined with many people having the same issues. Below 30hz a lot of budget amps seem to just start to dwindle off. Since 12hz-24hz is your main region in no way, shape or form should you run a budget amp. The lower your run the hotter the amp and subs get. I would not want to run a 250 dollar 2.4k amp (new) that low. The AQ is on sale can't beat that price new! AQ2200D Amplifier Also you said numbers you are doing more of a loud sq install with a target range of 12-24hz lol.

    Thing looks nice, too. Much cleaner than the BB.

    Runs colder, is better built and has a much smaller footprint.

    You made a good case, I'll keep it in mind. Thanks, murph.

    Anyone have one of these for me? I have subs to trade, lol...

The benefit with the AQ is the subsonic goes down to 10hz while most of these are 20hz if you plan on playing any subsonic bass. When talking class D amps once you get out of the budget section they all sound the same for the most part. A lot of budget amps have a hard time playing the lows 30-20hz.
    I'm with Murph on this one. Alot of the cheaper amps may do alright but when trying to push lots of power at the low freq's (20-30Hz) is where you will notice a big difference between the higher quality stuff vs. a budget amp. The ones murph metioned are all great amps. A few more to consider is the American Bass VFL, and the T-1500 or T-2500bdcp. Fosgate isn't the cheapest but the do make good power and have good customer service, just do not pay full retail or you will have buyers remorse like a mofo. Plus budget amps have very, very little resale/trade value if you want to change up gear later.

    Re: Need some pointers with pseudo SPL setup

    Murph is very spot on with his facts and ideas. AQ's are nice and affordable. BB's are hit and miss. I like them but can see I may need to swap them out later for a different product if I have any other amp failures.

    FYI I have a brand new clarian dpx11551 amplifier I may be interested in selling. PM me If interested.

    What are the odds of that, lol? PM for you.
