Hello all, I've been considering a new sub for my HT, and have been eyeballing the new Athena AS-P4000 or AS-P6000 subs as candidates. On paper, they look great. Unfortunately, none of the local retailers has any set up for demonstration. Has anyone here any experience with these subs? I currently have Athena speakers all around for my 5 channel speakers: AS-B1's, AS-C1, and AS-R1's. Any thoughts, insights, or comments would be most welcome.
