Can anyone comment on my situation? Currently have a Denon 4520 receiver to 5.1 setup, Speakercraft AIM8 Three's for LCR and surround, with an in-wall Artison RCC-600 sub. Long story short, the amp on my Artison is shot and I did I not purchase from an AD, so warranty repair isn't an option and I'm planning to ditch in-wall entirely and go with a standalone sub connected with a wireless transmitter. Space is extremely limited so form factor and size matters. Was considering the SB1000. Use will be 80% TV (sports) and movies at moderate volume (rarely loud), 20% music. Can anyone compare to the Artison? My annoyance with it was that it sounded great at high volume but just produced muffled crackles at my average listening volume. I don't need a sub that pounds, just something that adds life to what I watch. Room is not acoustically optimal - 14 x 30, 9 foot ceilings, open to kitchen, hallway, staircase. Goal would be to contain the bass to the main listening area as best as I can.
