Axiom Home Page Forums General Discussion Advice from Axiom Owners M3Ti Bass Hump

Hi all,

I'm a new user to this forum. Glad to be in the company of so many experts!

Question for you, is there any inexpensive way of mitigating the 90-150 Hz bass hump on the M3ti? With my current set-up, 1 kHz registers as 82 dB. At 90 Hz, I'm reading 92 dB. In order to "smoothen" out this hump, I've had to boost the subwoofer so that I'm averaging 86 dB from 40-80 Hz. The end result is excessive bass and sorely lacking lower-mid (150-300 Hz at 75-80 dB). All in all, the M3 is a great speaker, but I'd like to hear less of the "bump" and more from 30-80 Hz (hence the sub), and more from 150-300 Hz. It's fairly easy to detect the bumps when a sine-wave sweep from 30-300 Hz is done.

Can anyone please help? Is there a way to enhance the 150-300 Hz region? Thanks!

Here are my particulars:
- Speakers: 2 x M3ti and 1 x vp100
- Position of M3Ti: 10 cm from back wall
- Receiver: Harman Kardon AVR 240 (set to "small)
- Receiver X-over: 80 Hz
- Receiver: Bass and treble controls only. No equalizer
- Receiver: Bass = 0; Treble = -6
- Wires = Generic 12 AWG
