How much bass trapping would be overkill?

I know that from a practical standpoint, having too much bass trapping is not a very common concern... I'm thinking about the theoretical side. I mean, it'd be possible for me to build a control room where every wall surface had wall slats over a 4' space for hangers and the ceiling was entirely covered with panel traps or something. Since controlling the highs is relatively easy, tuning the room so the reverb time of the mids and highs were about even- or at least sounding natural to the average ear- would be a simple matter. Would that be a desireable room to mix in? Or track in? Or is this common practice in all of the multi-million dollar studios that I haven't seen? Kase www.minemusic.net

Kase - as we've said before the aim is to bring down the reverbtime of the room evenly. Adding bass traps will bring down the low end - how much yu need depends on how much of the other frequencies you intend to bring down. I've been in control rooms which have what you suggested. Tom Hidley rooms where there is 4 ft behind the walls with full trapping in the cavity. These are rooms that start out as 35' square rooms and the internal geometry creates the RFZ style design and claim a flat response down to 20hz. cheers John
