I bought one of these to augment my JBL-4311 Control Monitors, not that they really needed it but these days I am just so used to hearing systems with subwoofers that I thought I'd see what improvement this would make. My system is an Ariston RD-11S with SME Series II arm, TEAC 4300 RTR deck, HK 705 cassette deck, HK T403 tuner, HK Citation 11 preamp and HK Citation 12 power amp. This subwoofer is active (self powered) so my power amp is not used to drive it. The two sets of preamp outputs on the Citation 11 sure come in handy to connect this subwoofer. Purchased in Jan 2017, this 2004 subwoofer was in good condition visually. The first time I fired it up however, there was a buzz. So something loose in the subwoofer. I removed the rear amplifier/control panel/box and discovered two things that surprised me some: no polyfill or other material inside the enclosure (easily rectified with some new polyfill), and, a plastic amplifier box which had cracked around 3 of the 4 sides at the top flange that sits into the enclosure. I reassembled using small wood screws laterally through all 4 sides of the plastic box into the rear wall of the speaker box, then reinstalled the amp and control plate/cover. The buzz is now gone.
So the speaker works great. The controls are awesome, giving much flexibility in frequency range and volume. I have not tested the speaker-level inputs and I don't intend to. Line inputs from my preamp are perfect. With the 4311's not much bass is really needed so I ended up setting the subwoofer to a very low frequency range only, by ear. I think I now have a JBL speaker system that reaches those lowest of the low ranges the 4311's wouldn't quite reach on their own or which my aging ears don't hear any more (haha).
Overall I am very pleased with the sound this unit produces, and the way it blended very well with my 4311's. Only reason I didn't give it a perfect score was the surprising lack of polyfill and the cheapish plastic amplifier box, which by design, would eventually crack since it is exposed to the air pressures of the sub against the largest surface the amplifier box has.
So well worth the purchase, much cheaper than a new one with comparable stats and easily repaired.
I am super happy with the sound, and what else matters?
