This is a great sub. I read the other review saying that there was a buzzing noise. I have had no such problem. This sub is ideal for a high end home theater . VERY GOOD

Goes very low. Clear bass reproduction at low power levels. No whooshing sound (Sealed Enclosure).

Reliability. Two faulty subs in less that two months.

Bought this sub as part of the Jamo PDD.5 system from Harvey Norman, Auburn, Aust only a month or so ago. It has great bass, this sub really rocks in a smallish room and when its working that is... Anyway, while watching the T.V (on a low power level) this loud buzzing noise was apparent, with no bass sound output just this LOUD buzzing noise. After powering down my HK AVR630 AMP, the noise was still there, the sub didn't switch off which it should have being on (Auto). So I manually switched it off, removed the RCA cable from the AMP to isolate the sub, plugged it into a different power outlet, leaving off the RCA, and yep, the BUZZING NOISE was still there so something internal is wrong with these units. Harvey’s replaced the sub after TWO WEEKS, and you guessed it, after about 2 hours of Movies, the volume NEVER over 1/4 the replacement has gone… Seems there is a problem with these units, I spent over four hours setting up this system using only the very best Neotech cables, all the HK setting are correct… So it looks like I have a four grand system with no sub for some time, until Qualify the Jamo Aust distributor can give me some answers. I’ll keep this review updated.
