I recently finished my HT setup, I have the same Denon rcvr, Forte' 1's front, Academy center and KG-3's surrounds in a 12 x 12 semi-octagonal room.
It's sounded pretty good (esp. music) - but movies seemed to lack a little - 2 weeks ago a local HT company had a closeout sale of equipment and I was able to purchase a RW-10 for ~$200 - what a difference it made.
Regards,
Shawn
I would like to clarify - I only use the sub for movie LFE, It made a huge improvement - but I would recommend a 12" SUB and will probably upgrade to one once the $ is available. ( the 10" does pretty good, but I have seen some limitations - esp. Darla tapping on aquarium on Nemo DVD)
