This question goes out to all the experienced AQ guys that say that AQ subs "pound the lows" when tuned at 36-38hz. What is your definition of lows?
In doing research for my latest build it seamed the general opinion was that there was no point in tuning a box for AQ subs below 35hz because they would still play plenty low when tuned higher. Well I would have to disagree.
I've been enjoying my new woofers for a little over a month now, and although I am very happy with they're overall performance, I was really not fully satisfied with they're low end performance. That is until last night. Yesterday I decided to do some experimenting and make a port reducer to drop the box tuning down to 32hz, which is what I normally tune my boxes to. All I can say is WOW, that 4hz drop in tuning made all the difference in the world! The lows (35hz and below) are so much more powerful, and the high bass (50hz+) and above is nowhere near as peaky and annoying as it was before. I don't consider anything above 60hz to be bass, and before the tuning change those high notes would come through much louder then the sub-40hz notes, which was really annoying to me. Now with the tuning change everything is much more flat, and amazingly my peak frequency didn't seem to change any, it's still right around 40hz
So anyway, the moral of this super long post is that IMO, AQ subs (at least my sdc2.5's) do in fact play very well in lower tuned boxes
