I just built an 8 cubic foot sealed enclosure and installed a 21 inch Dayton Audio PSS545HE-4 driver. It is rated at 2000 watts RMS at 4 ohms.

I was going to power it with a 2 channel Crown 2502 bridged to a single channel. The power rating for this amp at 4 ohms is 2400 watts RMS.

The problem is, there are no Crown 2502's in stock. The MSRP for this amp is $689.00.
I would like to be able to get into sub 20Hz territory.
I have increased my budget to $1000 and perhaps a little more so as not to eliminate what might be a better amp.
My first question is, would the Crown be the best amp given these parameters? I did find one available used but prefer not to purchase used.
If not the Crown, which amp would you recommend?
Another question related to my subwoofer, I have an Onkyo TX NR838 AVR.
Ideally, I would like an amplifier that allows me to tune it so the frequency response curve is as flat as possible. I do not remember the term for that function.
Is the subwoofer tuned before the AVR or is the AVR tuned first, so the LFE is correct. Forgive me if I am not familiar with any proper terms or technology. So please try to correct me on this.
Thanks,
David
