Velodyne DD-15 setup question


Hello

I own a DD-15 that I use mostly for HT and once in a while in a 2 channel environment. My system consists of a univeral Esoteric UX-3 SE going into a Mcintosh C2200 preamp and into a McIntosh MC402 amp and onto some PMC IB1's for my 2 channel setup. In the same rig I have satellite and the above source going into a Myryad MDP 500 G6 processor and to the 402 amp and Odyssey HT-3 3 channel amp. The Mcintosh C2200 acts as a pass through piece in this realm. My question is.... should I be setting up the DD-15 for both the 2 channel setup and the HT setup separately? I'm thinking of the CUSTOM setup (#5) to augment my 2 channel listening if needed, and the other tailorable setups (1-4) as my HT. Should I be doing my room correction sweeps for both modalities? Should I set my processor to control the sub characteristics or leave the sub to control all below 80 Hz? Should I set all things on the processor as I want it before doing the room correction sweeps? I know it sounds a bit complex, but I'm counting on advice from my fellow audio/video docs! Thanks. Dave

Theo, Did you try setting the xover from sub to Revels lower than 60hz, say around 30hz? A 30hz/12db roll-off still delivers bass up through 40hz. My Merlin VMXs have similar bass extension as your Revels down to 30hz. With the DD-15 & 2CH, if the main speakers are up to it, I find it cleaner to minimize overlap in the xover region by rolling off quickly down low. I set each preset identically, except for various volume boosts for different listening levels and source components. The ear likes 5db or more of boost in bass below 30hz, but things get muddy if you're boosting bass in the 40hz-60hz range. I agree that the DD sounds better with the servo control set high for all sources.
If the soundcard has full-range analog XLR L/R outputs, you can convert them to RCA with a plug converter or a custom cable and connect to the RCA L/R line-level inputs of the DD sub. Then set the sub's LPF & digital EQ to blend with the Tannoys. Should work fine.
