I am not sure on a one band EQ. I would think that with a low level output on most HUs, and a filter on the amp, you should be cleaning up your bass freqs pretty well before they are amplified.
as far as the subsonic filter goes, It dosen't say that it is adjustable. I had 2 12 JBLs and now have 2 12 audiobahn natural sound subs.. neither of them competition, and they pick up around 10Hz according to the frequency test on bass mekanik's sonic overload cd. No you can't really hear it, but if I can feel it with average subs, competition subs should really massage you. If this subsonic filter cuts out everything below, let's say, 15 Hz, you lose alot. I have never heard of any country, rock, or pop songs hitting sustained freqs below 15Hz, so the 'damaging subsonic frequencies' aren't going to be there unless you purchase a bass cd that advertises it. basically subsonic frequencies only damage speakers if they are isolated and last more than let's say 10-15 seconds solid.
If I were going to spend money on a crossover/EQ, I would go with a three channel crossover that lets you set upper and lower frequency limits for highs, mids, and lows. This way you have total controll and can set your own 'subsonic frequency limits'.
That is just my opinion.

there will be subsonic bass in almost all recordings. I have used the basscube on many cars, and it is a bassheads dream. My current amp(PG Octane) has one on board. If your HU already has an adjustable output, you really do not need it.

you can find those on ebay for a little more then $100

is the subsonic bass in the recordings actually dangerous? I have played the test tracks multiple times that I mentioned at very high volumes and I never noticed a difference in the performance of my subs. the test tracks go from 80Hz to 1Hz in 1 second increments. I know making your subs move 1 cycle per second builds up alot of heat with no ventilation, but subsonic frequencies mixed with upper level sub freqs shouldn't do anything because the speaker is moving air through the voice coils..
I hope this does not appear to be an arguement, I just want to understand the hows and whys.

I have a hook up at phoenix gold so i get all my stuff at just over cost... direct from the factory... i can get a bass cube for under 100$ i just wanted to make sure it was worth it even at that price thanks ttocs

it is not necessarily bad mind you..... It can cause damage if played at high volume for long lengths of time. But is is kinda like taking the boat off the trailer, and leaving the trailer attached to the truck. It does not do anything other then load you down. If the speaker is trying to produce subsonic bass, that you cannot hear, wouldn't that take away from all of the rest of the freq's that you can hear?
No argument to worry about mang... Feel free to question me or anyone, anytime... I have been wrong before, will be again....
