Yep, exactly the same for me. A MTM box "coupled" to a "sub" box, although it will be a passive woofer with a target tuning frequency of 30hz. The MTM I was planning to be an acoustic suspension for tighter mid-bass.

The dual-woofer concept would be 2 horizontally-opposed side-firing woofers, ie one on the left one on the right. They would fire *in-phase*, to prevent bass cancellation. With the potential for High SPL, it seems this might get messy and the cabinet might have to be *huge*, not to mention it might kill my 110/ch yammie amp.

Any thoughts?

To be realistic, I'm not starting to lean towards a front-firing 10" or 12". It's just a matter of getting the aesthetic proportions right so it doesn't look like a monolith in my living room... ;-)

Thanks everybody for your thoughts!

p.s. Anybody know where i can find a picture of the old AR9's?
