Nice traps Simon.

Didn't realise you were into that sort of thing.

What's the effective operating range of those? I'm using some 3ft x 1ft x 1ft corner traps along with 2" tiles + eggbox tiles. I've found the wall treatments are effective above 800hz but the bass traps are somewhat dissappointing in performance and given their bulk and imposing nature I'm considering ditching them altogether and just settle for a little more EQ in the 80-200hz. I'd have a hard time bettering the measured performance above 200hz but have some serious problems in this region with a huge 13dB broad peak at ~115hz. That makes things sound terrible with a slow and plodding nature without some excessive EQ, the bass traps only seem to improve this by a few db's at best and towards the upper end(200hz). Below 100hz and they are useless of course.

I've tried a couple of traps now from Auralex (LENRD's) and the cheap ebay ones(3ftx1ftx1ft). I'm guessing that I'm using inferior traps with exagerated specs and naff performance in the range I'm looking at. I've been looking at RPG and Auralex Venus but these traps are huge with a price tag to match.

I was wondering if you could make a more informed suggestion. Other than that I'll have to leave with the EQ and ineffectual traps.
