AQ HDC3 10 air space and tuning?

[SPY 5,000+ posts]

I'm trying to design a box for my AQ HDC3 10 and I would like opinions from those who have experience with these subs.

I was thinking 2.0 ft^3 tuned to 35 or 2.5 ft^3 tuned to 34

Suggestions anyone?

Amp is rated at 1400x1@4ohms but is fairly underrated.

 

[poundindak69]

oh so you goin to wire the sub to 4ohm

yes, the amp is only 4ohm mono stable.

It's a PPI PC 21400.2

Well this is what I came up with.

I like the idea of 33hz tuning but I originally thought it would be to low for this sub and it's 1.98 ft^3 after port displacement before sub. 30 in^2 of port
