Tight, but not low
on October 16, 2015
Posted by: Grant58
This sub is nothing special. I picked it up this evening from a local BestBuy hoping it would provide some low end below 30 Hz. (organ pedals, some contrabass instruments.) I admit I was very suspicious of the 18Hz frequency claim, since there was no +/- dB associated with this spec, but the manufacturer's 18Hz claim is ludicrous. I would have been OK with it 'only' getting down to 25Hz or so, but this sub drops off rapidly below 35 Hz: it is down -7dB at 30Hz and below -30db of its 40Hz response by 25 Hz (measured using test tones and an SPL meter.) On the positive side, there is little in the way of unwanted harmonics at 25Hz (it is virtually inaudible at this frequency), and it seems like a reasonably 'tight' sub for the 30-80 Hz range, which is what most people will want it for. Unfortunately, that does not include me as I've already got fairly good response down to about 35Hz from a JBL Control SB setup and another sub.
No, I would not recommend this to a friend.
