The now user of this box has it in his living room, built his own amp, a 120Wrms mosfet on a toroidal, mounted externally (inside his other amplifier) and cross-overed using an active 12V car job. See WES code AX100 (page 18-10 in WES Cat 2003). Simple but sweet. Always on and main speakers matched with are the old 10" Philips kind, you know, the ETI project jobbies from the 80's, with SP10-120s and DT40s. He reports satisfaction in the sound and that it rattles the windows if desired, go the XLS 10 !

The port is an elbow, about as long as I could tolerate, the longer the better because the wider the less port turbulence, and I tell you, this sub exerts some air thru that port! So much, I then routed the edges, inside and out to reduce the turbulence distortion, but still not satisfactory to me (after this I went for the 12" with a passive radiator to eliminate ALL port noises), mind you, the now owner does not complain, but probably because he went for the Bose option of hiding the sub behind some furniture where such sounds are muffled anyway, oh and he is old so probably doesn't blast it much (Just kidding! Playing $2 CDs thru them are we? LOL), big room too. Nice tone, but sounds a bit peaky to me, was trying to beef it up around the 50Hz mark as these subs do sound a bit boring due to their complete lack of distortion and resonance, again, only as an experiment. So check the dimensions as they could do with a bit of work, suggest you aim at protecting the resonance of the XLS10, the speaker knows best, so tune to it! I tuned to a fictitious assumption. But the basic ported design still holds true. And the sound of these guys really do rock.

Any comments, please let me know!
