IB capable 8" or 10" subs

[jroo]

Looking to build a manifold for 2 IB subs firing through my ski pass in my sedan. Because I am using a manifold, I am limited to 8" and 10" subs. I am following the Qts over .5, lower Fs, rule. Anyone know any subs that fit that bill? I would also like to stay under 300 dollars for the pair. Kicker Comps, a few Pioneers are already on my list. Any others that I should think about?

What about the NVX VCW 10" - Qts 0.52, Fs 29Hz

More importantly, you need drivers with a lot of xmax. Small drivers typically aren't conducive to IB sub duty because you need a lot of displacement. You may be better off doing a sealed/ported alignment.

Go with the Dayton reference HO 10's if you can fit them. Steve is completely right you need as much cone area and excursion as possible. I actually prefer a lower Q driver.
