DSPeaker 8033 Anti-Mode and REL sub, anyone?

Anybody willing to share thoughts? Pleaaase??

Hey Lewinskih01,
I have a REL B2 Subwoofer with Harbeth Monitor 30 Speakers in a small 11.5 by 14 room. I run the Monitor 30's full range with the Sub as low frequency fill.

I'm using a DSPeaker 8033C with great results. Tim Ryan of SIMPLI FI AUDIO was great help with my set-up. Tim also made-up and provided the required stereo output to mono cable between my preamp outputs and the 8033C input.

I was able to make an appointment with Tim to stop by my home, we both live in Southern California. Tim utilized pink noise generation with special supplimental room monitoring equipment to read & graph my room levels. With the 8033C connected and calibrated, Tim was able to dial in my REL Sub with a crossover point and output level to fall seamless just under my Monitor speakers. The end results was a virtual flat response. Amazing what you can do with the correct equipment and knowledge.

I'm very happy with my DSPeaker 8033C Anti-Mode and the assistance I received from Tim. We know it works OK with low-level inputs into a REL B-Series sub.

If possible, the best would be to audition the Anti-Mode in your system and set-up with a return option. Then you would know for sure. Best of Luck.

Thank you very much for your reply!

Unfortunately I live in a country where audition is not feasable.

I'm a bit confused because you mentioned the lo-input is what you are using, which does not go through the ABC crossover/network inside the Rel, but before that you mentioned "Tim was able to dial in my REL Sub with a crossover point and output level to fall seamless just under my Monitor speakers"...meaning I guess a crossover is being used. Is that an external crossover between the preamp and Rel?

BTW, running the main speakers full range is also what I intend to do, so thanks for sharing your experience. It really is spot on!
