CR symmetry of slot resonator walls?

I am hoping for John to respond to this. :D What effect does having a varied depth slot resonator on only one side wall OR having 2 different size slot resonators or absorbers on the 2 side walls have on the acoustic symmetry of a CR room? Posted on this forum I have seen CR designs and pics of CR rooms which have these one sided slot walls. Makes me wonder, if when trying to mix (for example) the bass drum or bass in the middle if of a mix, would the engineer feel like panning the instrument to correct it OR would balance of some instruments which are panned actually be not balanced? I posted this question in acoustics, it may have gotten “buried” in the questions of my post and it did have a limited response. So I post again (so it won’t get lost). AVare’s answer was: “It reduces it. How much depends on how the different the two sides are, the frequencies involved etc.” In my case this is a one-room studio which I plan to build for good isolation (I am aware of losing isolation with slot wall, 3rd leaf), real small about 1000 cubic feet with dimensions or 14.5’ long, 8.5’ wide and 7.5’ high. I guess my second “question” would be how much of an affect this could have on acoustic symmetry, is it enough to be worried about especially with only one side wall slot resonator? I’ll post diagrams if asked. Thanks. :D Marc :twisted:

There are two factors here. One is splaying of the side walls which is to create the RFZ across the fron of the room.Here we are talking about reflections. the other factor is low mid absorption created by the slots. The absorption covers the whole room as far as the low mids are concerned whereas the reflections are purely related to the first reflections, not the overall room response, i.e. the decay. they are two different aspects and are not related IMO. cheers john
