RE: setting up a listening room

1) so how far do you sit away from your speakers? are they near-field or midfield?

A bit under 8'. Technically, that's going to be far field, even for 2 way monitors.


2) what do you mean "short wall placement"? does that just mean the shorter walls are to your left and right (when sitting)? or does SWP mean that the desk is just a shorter distance away from the wall? sorry, i just wanna make sure i'm understanding correctly.

Short wall placement is having the short wall behind the speakers. Long wall placement is speakers is having the long wall behind them. Most people do short wall placements. Some of us crazies like long wall placements.

3) can you give me a few quick, easy tips on junk placement and absorption?

Well, a lot depends on what the junk is and whether it absorbs or reflects. Soft things tend to absorb so things like old rolled up carpets may have some absorption value. Hard surfaces tend to reflect. If you've got a lot of hard surfaces, angling them randomly so they don't all have flat surfaces facing in the same direction is best. That way you'll get some scattering of reflections. Keeping absorption close to joins between 2 room surfaces (corners, floor/wall and wall/ceiling junctions), similar to bass traps or at early reflection points are good ideas.

4) what are cheap substitutions for accoustic panels?

Look in the FAQ for Jon Risch's DIY acoustic treatment instructions for reliable DIY approaches. Things that can be found around the house that can be used to some effect are rugs and carpets, old cotton-filled matresses like futons or foam mattresses, several thicknesses of blankets, thick curtains and the like. Books are also useful for absorption. None of them are as good as the proper item, even DIY panels are usually considerably better than any of the substitutes but the substitutes can have a positive effect if used in moderation. Too much absorption within a narrow frequency bandwidth is most definitely bad and to be avoided.
