Has anyone heard both the 1000 ultra and 1200 ultra?
I heard the previous series (SPL 800R/1000R/1200R), which shouldn't be far away and the incremental improvement should be the same.
The 800R was the best small sub I'd ever heard, until the Paradigm Seismic 110 arrived.
IMO. There was a noticeable step up to the 1000, but when I compared it with the 1200R, I thought the difference was worth the extra, in a room 14' x 22' x 11' (I think it was around £200 more).
I see you own the 1000 ultra, and I'm not sure it would be worth the hit to change, especially as the Ultra series is a good bit more expensive. This is just my opinion, so you would have to hear the difference for yourself and see if the cost to change is worth the extra performance you will get.
