Kevin - I found that thread in the archives, but it just referred to a different thread (with a dead link). I also found this thread from June 2003 about the Sherbourn review at Audioholics. Check Scott's post at the end of the thread. From soundhound's comments, there is yet another thread somewhere else in the archives that also addresses this, most likely this one from February 2003.

In both, Scott says this:

There is a very simple way to find out if it works on your system or not if you have a subwoofer with auto on and off sensor (I believe every sub does). If sub doesn’t get a signal for a few minutes, it goes into “off” mode with indicator light turning red (at least mine does). Once it senses an incoming signal, it automatically turns itself on with that indicator light turning green. Try this: mute or disconnect all channels except for center and LFE (subwoofer) channel. Make sure the subwoofer’s auto on and off indicator light is visible to you then run the test. Play music, DVD, frequency sweep or whatever that has some mid range and bass in it. Let me know how it turns out.

Kevin C Brown,

Yeap, the article does talk about the exact same problem...

Since these products are basically the same except for cosmetics, it appears this looking like is a real problem if the 950 is used the way Joel is describing.

Hopefully Scott can give some insight as to the test results...

Check out Scott's posts in both threads that I linked to. In at least one, he mentions double-checking with the engineering team to verify that the behavior quoted by JT Clark above does apply to the 950.

From what scott says about these "problem" in June 2003

"First, while we have the highest respect for reviewers, there are times where the methodology they employ in testing produces results that do not provide a full picture of how a product operates. Secondly, just to maintain our own sanity, we asked our engineering team to validate the operation of the crossovers, and they reported that everything does work as it is supposed to."

I only guess what methodoly applied outlaw in these case.

Hello Everyone,

I leave for Taiwan for a few days and look what happens! Sorry it took so long to respond. The Model 950's bass management does not create gaps in the frequency response.

In the following graph , you will see that there are no holes. In this test, the Model 950 settings were

Front: small, 40 Hz.
Center: small, 100 Hz

As you will see, all of the center channel bass from below 100 Hz was reproduced by the subwoofer.

Joel: I am confident that your unit also behaves this way. However, if you would like to send the unit in for confirmation, please contact the office.

Best,

Scott

Scott,

Thanks for the information...

What a trip... Is that allowed...

:-)

Neat. Would have been nice to see the surrounds too, but ...

So somehow must be a test issue.

Sorry Kevin,

Busy trip...didn't want to take too much time out of the schedule. I'm glad this helped.

Best,

Scott
