IB capable 8" or 10" subs

[Jroo 10+ year member]

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?

Tons to choose from. Qts should be over .7 and fs as low as possible- ideally under 30hz but its hard to find 8s with a fs that low, 10s would be better.

I have a set of old school MTX Eliminator free air 10s ..some of the best you can buy if you can still find any . There’s a new single 12 on eBay right now .

Make it fit. This sub totally destroys whatever kicker or pioneer you were thinking of.

It doesnt have to fire directly through the ski pass, it can be sealed but angled off set slightly to get the woofers to fit. sort of like this but IB style firing towards the ski pass.
