Hi Mors, have you watched absolutekarl to the end? I cannot tell you too much about them as they are his invention. blacksea.coolroche.com is his website, tell him I referred you to him. We used Linear x to measure, Rt30 was usually best, using pink noise, to excite the room, at numerous...

I have treated 40+ rooms with tube traps and they work a treat. Look up absolutekarl on YouTube for his very thorough explanation of room acoustics. Karl, is the inventor/developer of the RaTs system has obviously treated many more rooms than me. He speaks and preaches no nonsense acoustics.

JStewart A room has a bass cut-off point due to its physical size, hence the uneven bass response at very low frequencies in small rooms. How low a freqency do you need to hear? The lowest note on a grand piano is bottom A, 27.5Hz. Yes REW can measure 15Hz in your 12.5ft room but it only...

I did not say that you are wasting your money, that is for yoj to decide. At such low frequencies you will find that the amplitude varies in different parts of the room along its axis at the same height. Vary the height in a fixed position and the level will also change. If you can, take the...

Hello Kakkdu, It's not a suggestion it's a fact. To reproduce or genrrate a note or tone with a frequency of 20Hz you need 22.5 feet of airspace in front of the generating element otherwise you are not hearing the sound at its full amplitude. It is also worth bearing in mind that the "sweet...

Hello Hiawatha, In your case forget room ratios as a design method, you will get nothing that is of any use to you! Hold off buying your bass speakers until you have some idea of the lowest frequency your room will be able to reproduce! Perfectionist is absolutely right in suggesting room modes...

Hi, the Rode NT1 is a pressure gradient mic not suited to acoustic messurement as it does not respond equally to sounds from all directions. The EMM6 is a a pressure ooerated mic which is what you want for acoustic testing, in fact theore are ragher s lot of them around these days, many I...
