Axiom Home Page Forums General Discussion Advice from Axiom Owners Should I upgrade my M22's?

Keep in mind that the response graphs are taken in an anechoic chamber which because of limitations due to the size of the wedges isn't accurate below about 90Hz. The minimum on the M22 impedance curve in the NRC measurements in the SoundStage review indicates that the M22 enclosure is tuned in the 50-55Hz area. My own in-room measurements with my M22s show pretty strong bass down to about 50Hz, so even a 60Hz crossover(which resulted from the Audyssey measurements)might be justified. I nevertheless manually reset the crossover to 80Hz, so that my EP500 would handle more of the lowest bass load and the M22s less.

Good to know. Thanks.

Today's status is: On FedEx vehicle for delivery.
Yip!

80hz is usually the best starting point not only with bookshelf speakers but with a lot of tower speakers if you have a well designed subwoofer. There is nothing wrong with trying 100hz. However, the further you increase beyond 80hz the subwoofer starts to become more and more localized. A higher crossover point can work and be beneficial with careful positioning of the subwoofer(s) close to the mains.

Let the Beta Test's begin!

Fedex delivered on time. Everything looked good, We ran the wires last night (leaving extra for repositioning) and today we start working on position and all that Jazz.....

Ooooooo!! I like Jazz...

One tip I have as I just did this last week. Play your m22's but on direct mode and see how they sound without anything interfering. I was more than impressed with the amount of bass they are capable of producing, actually was shocked. Don't get me wrong i love them coupled with my svs but some loud jack johnson by themselves is pretty sweet sounding IMO.

Speaking of M22's, one of mine has a bad subwoofer. Axiom is sending a replacement but it will take some time to get here.

Is there any issue using the M22 with the lower subwoofer disconnected while I wait for the replacement?

It's just a woofer, not a subwoofer. I don't see how operating the speaker with one woofer missing could damage anything, but it definitely won't sound right.

It will sound at least half-right though...

Should be no problem running with one of the woofers disconnected. Your receiver/amp will see a slightly higher impedence but that won't hurt anything.

Woofer, I stand corrected.

And as long as it won't hurt, it has to sound better than what it's doing now...
