Hi there,
I bought one getting on for about a year ago. The build quality on these is excellent for the money, especially if you go for the high gloss black like I did. Should certainly help on the police front, as it looks very smart next to the rest of my setup.
It's actually a pretty small box as well.
It's my first sub, so I haven't really got anything to benchmark it against other than my friends Kef all in one system, but it definitely blows that away.
I have it hooked up to a (fairly) old Yamaha surround amp (DSP-AX-620 I think), with that then going through to an Armcam 8R for when I'm just listening to music and it's very capable in this area, and never sounds strained, even when I've cranked it up a bit (alongside my Tannoy bookshelf speakers - mounted)
Same goes with films. Had Tron Legacy on last night, and all I can say is it continues to put a smile on my face listening to it; the range of this little box is impressive!
I'm using it in my flat around 4m x 7m and it's got enough kick in it to get the ceiling shaking - my neighbours no doubt love me for this.
Took me a few months to convince myself that i NEEDED a sub, but glad I did. I've had plenty of comments from friends about that powerfull little box in the corner.
Go buy. You won't be disapointed.
