This is worth the price! As a drywaller, having a decent subwoofer is a great accomplishment to me.

Nothing at all.

I love the this product! Thanks Akron SEO

none so far

I would highly recomend the Q150, I did hav ean older version that hummed, which has now been replaced, with the new version, totally solved the humming problem. SEO Tampa

I doubt it's the best sub in the World but for the £385 I paid for it, I'm more than happy.

PARTY BUS FOR RENT NEAR ME thinks the amplifier is really nicely sounding.

there is no negatiity yet

The Q150E is only a little larger than the REL Quake, but it performs far better. I've used it for home theatre and it's fantastic. I'm currently using it in conjunction with my Hi-Fi speakers, and it opens up the music. Regards, Irving Concrete Company

Bass is not that powerful.

Easy to integrate. Huge improvement to soundstage size and depth!

Slightly rubbery bass compared to putting the same driver into a better designed larger cabinet for the driver. I also have the REL B3, so I know!

When broken in and setup properly (including gain/ volume- see comments in Weaknesses), this compact sub really filled in the ranges on my Eosone RSF 400 and B&W 602 S3. I use the recommended hi-frequency input with a Neutrik Speakon cable and crossovers were set just above the speakers' -3dB bottom end. Rest of equipment included NAD C350 amp (going to try Roksan Caspian next), Yamaha CDR-HT1000 source, and Straightwire Chorus interconnects. The bass is lively and tight then and makes the other speakers more revealing in high bass and midrange. Quite a value/ steal for the pittance i paid in a garage sale (price includes a new Neutrik cable and AC cord).

Not going to be as powerful as best 12” or larger sub. Then, there’s the notorious rattle . For me it was heard at every volume, so I did the free air woofer test... It was still there so it wasn’t the enclosure. Moving the cone by hand even a little elicited a metallic rattle so it was the voice coil on the OEM REL AX10 woofer. This was replaced and then it sounded heavenly.

bought after recommendated by a friend in 2002 for arround €800,- it proved to be worth it !
together with 2 Quadral Phonologue Amun mk IV and the Quadral aurum base as a center, powered by Denon 3802 no signs sofar to replace any of the above........
