I have a pair of the M3Ti, hooked up to my stereo only system. Last night I was using a test disc to check for my
in room low frequency response, using the rad shack digital SPL meter. Now don't laugh but I got a low limit response of around 40-45Hz. Is this possible???? My reference level was at 75dB, with the response at 40-45Hz area at 76dB. Was I using the meter wrong or is this actually possible with a 6.5" woofer????? Any comments....
it is POSSIBLE
with proper placement I got my M3's to give me a lot of bass, especially when closer to a wall or in a corner.
I have mine on 26" stands approx. 18" from rear walls....
are you playing hip hop, rap, or something with low bass such as blues or organ music?
No hip-hop or rap, but some blues and classic rock mixed with a little current hard rock. At the time I took the readings I was using a test disc with warble tones at various freq. 20Hz,25Hz,31.5Hz,40Hz etc.
Hi JB
Do you have the analog Radio Shack meter set to slow? If so, then your room and your M3s get along very, very well!
C weighting and fast response, but I have the digital SPL
John, that's what room reinforcement can do for bass. One of the first things I did after I got my M22s was to use my Stryke Test Tone CD to check for bass response. I got strong response at 50hz, definitely weaker but still usable at 40hz and nearly inaudible at 32hz. Remember, 40hz has a wavelength of about 28 feet. Room surfaces reinforce sound within certain distances from the speaker in relation to wavelength. A frequently used rule is that strong reinforcement is obtained up to about 1/10th wavelength from each room surface. At 40hz that's about 2.8 feet, and you could be getting up to about 9db of bass reinforcement from the floor and two nearest walls up to that distance.
yes, but before getting to excited and glueing the speakers to the wall to get this bass rolling, room modes produce peaks and valleys depending on the frequency. Also, mid and highs smear (affects soundstage). Best setup is power-amping with 2 corner-subs and far-off-wall speaker stands with monitors. But that's another league and more toys to fiddle with instead of hearing music.
