Q15 Compact 15" Bass bin

is the 15 plan available online?

Hi guys. I promised in another thread a week or so ago that I'd put up a review of Tony's Q15s since I recently had a pair built (thanks TMAL) and have now been using them for the last month or so with more bookings coming up in the next few weeks.

Initially I have to admit I was skeptical given how physically small these cabs are but Tony was kind enough to let me test one out to see if the design was what I was looking for and these things really do deliver! An easy one-man lift into the car and up stairs or for stacking I have had a few funny looks (especially from DJs) as these things aren't much bigger than the top cabs I use but once playing I've had a couple of people comment how surprised they are at the amount of bass coming out of such a small box.

A couple of weeks back Tony brought his pair down to a gig with a friend's band at a local pub and we ran two a side for the afternoon. The system had plenty of headroom left and bass was full and powerful a good 40ft back at the sound desk and when we turned up the bass towards the end the bassist (a fairly serious chap most of the time) couldn't hide his grin.

I'd describe the sound as full and deep but it still maintains plenty of kick-drum punch. I've used them so far for rock, dance and some chart music (wedding) and they've handled all of it with ease. With some house music the B6 EQ can be turned off and a bit more can be added around 80-100Hz to get a very fast punchy sound. I have also tried a tracks with very low bass like the Void 30Hz test track and, although it was audible, the response does tail off quite quickly below 40Hz as could be expected given the enclosure size and the processor settings. High pass at 41Hz Butterworth 12dB/oct with 8.7dB Parametric EQ at 41Hz (B6 alignment). Excursion seems to be well controlled and I've not had any issues running them one either side of a 1000W/ch into 8ohms amp.

Something people keep pointing out is the rear porting. So far I've not noticed any more sub behind the speakers than infront and that's with both indoor and outdoor gigs. As Tony has said elsewhere, these are designed to be used in small numbers and not huge stacks where the rear porting would cause problems.

If anyone has any questions then I'll keep an eye on this thread or you can PM me. Tony obviously knows more about the design but is often too modest about how good his designs actually are! Big thumbs up from me. 

And finally a couple of pictures:
