Do you think you need a subwoofer?

Dear Eldartford: +++++ " My point is that the crossover electronics should permit the frequency to be easily changed, and one should not be afraid to adjust it as freely as the volume control. " +++++

I respect your point of view and certainly any one is free to make about what any one think is better for achieve the quality performance that are nearest to its music sound reproduction priorities.

My point of view is a " little " different from yours: I don't like to use the subwoofers ( crossover/volume ) like a continnuous " bass equalizer ". My first target is to obtain the best quality sound reproduction from my main speakers lowering the Intermodulation Distortion through let it them free to reproduce frequencies from 60Hz and lower and my second target is to obtain a better quality bass performance through a dedicated/specialty audio item ( subwoofer ) and to obtain ( too ) a lower bass response.

Regards and enjoy the music.

Rauliruegas...At first I took the same approach as you, (and everyone else it seems) and I tried to find the a frequency for "best quality sound reproduction". I never seemed to get it right. It took me many years to realize why: there is no one best X/O frequency, at least for my system. It depends on the kind of music being played. I do not use the X/O frequency as a tone control. I have my system tweeked up so that there is no audible or measurable (RTA) change when I sweep the frequency. But with music that has heavy LF the six 12" and 15" subwoofer cones have the "punch" that folks say is missing in Maggies.

This is the name of the game. In my system it is an audible change when I sweep the frequency.

Rauliruegas...I forgot to mention that when I sweep the X/O frequency I am listening to and observing a white noise signal. Music is another story, which, of course, is the reason that I vary the frequency. My ability to sweep the X/O frequency without audible effect may not be usual, but my claim is that it indicates that my custom designed SW systems are well matched to the MG1.6 speakers.

Dear Eldartford: +++++ " My ability to sweep the X/O frequency without audible effect may not be usual " +++++

Certainly it is not .

In your Organ example ( crossover 200-300 Hz )and in your very well designed system I'm still worried about Intermodulation Distortions that with that high crossover frequency and with organ music it will be really high IMD: the organ music could go down to 16Hz or lower and normally in that kind of music your sub's are trying to reproduce frequencies in the very low bass: 16Hz to 40Hz and at the same time you are asking to reproduce in clean manner frequencies ( very critical audio range ) between 100Hz and 300Hz+, well this is what I'm concern of IMD.

Anyway at the " end of the day " you are crossing over 80Hz that makes more sense to me.

Regards and enjoy the music.
