a marants 7010 amp and a emotiva xpa3 gen3 amp using rbh impressions speakers comprising of 4 r55ti front and rear speakers r56ci centre speaker 2 r5bi as extra rear speakers 4 mc-815 in ceiling speakers to make it 11.4 i will connect front and centre speaker to the emotiva and the rest to the marants using blue jeans speaker cables and a oppo 205 4k player thanks

I think you'll find a bit of a disconnect there!

Yeah, as written, going to have to change 'cheap' to 'if you have to ask the price, then you can't afford it' or change everything else.

Do some reading around and get a pile of the best displacement-per- drivers you can. Go infinite baffle. Something like 8x JBL GTO1214 and an NU6000DSP would be a good start. Still coming up towards 1000, though.
You've spent a good amount of money on the rest of the system, and yet you're after top-performance subs for bottom-dollar prices. Can you see how that's going to cause some difficulties?

If you're near Sheffield, give me a shout and maybe I can bring some kit to try for an afternoon.
I've just finished a set of four 15" subs that I use for live music. Felt the bass just fine at 40' outdoors. They don't go as low as you might want for home theatre, but indoors they'll make themselves very well known in all the ways you describe. You could probably DIY them for around 1500.

For slamming pounding bass, you need to move a bunch of air 80-200hz.

Chris is right, use many 15's.
Under 80hz is more rumble than slam.

Using same room and subs, double 15's work well for pounding bass, better than many other combinations I've tried.

Focusworks is pretty nice. Not cheap. But nice.

I agree with infinite baffle...OR some sort of setup that uses a feedback system (aka, servo)

But what others have said; if you want to compete with the best systems, 'cheap' is not going to cut it. The only way I see that happening is buying used bits of kit, which would surely come with risk.

True, DIY is always going to get you the best bang for the buck, but I think you need to be reasonable with your expectations...

I do wish you luck in your endeavors..

Cheers
-Steve

... "Subs" = 80 Hz and below. Use Servo-Control. See example.
