Hey Perry
Well, you can't beat the bang for buck of the X-Statik kits but not fully OB. The wedgie and NX-MTm kits will need subs that play up pretty high, near 200hz for the wedgies, a bit lower fo rthe MTM's.
The NX-Otica's are around $2k including the flat pack and afully Ob from tweeter to woofers. See my post above... even without the dsp aditions in those graphs, they reach down to a solid 50-60 hz in some rooms.
I do need to get mnore wings /braces cut for the Otica kits...., thankfully we're getting going on some cutting once again.
Is your buddy up here in Canada ? If so and he ever gets over to the OK valley, he is more than welcome to stop by for a listen
