I think you are correct but there are exceptions. Large Wilsons like the Alexx or XLF are the exception. Wilson strongly recommends that these speakers be run full range (no HP) so that the Watch Controller does not affect in any way the signal going to the Alexx or XLF. I have tried it both ways and can say conclusively that LP only(no HP) works best. The crossover coloration is noticeable with the HP engaged and Wilson specifically emphasizes the significant effort they put into the HP filters. That's why big Wilsons do not have exaggerated 30-50 Hz bass. It would make integration with a Thor or Subsonic impossible without a HP crossover. Both of these speakers possess both front and rear ports so that bass can be further reduced to allow the sub to perfectly integrate with the speaker. Using the front port decreases bass output in most rooms. However for me I find that the rear port works best and with the Alexx pulled out significantly from the rear wall.

Back when I had my Maggie 1.7's I ran two SVS subs. They blended so seamlessly that whenever friends and audio club members came over they couldn't believe I had two subs in action.

The thing about subs is that you have to take the time to dial them in and keep their output at a level where they don't say "Hey, look at me!"

Once the Maggies left for a new home, and the big Canton's arrived, the subs are not being used. In my smallish room they're just not needed as the Canton's produce a prodigious amount of deep bass.

You know I get what he is saying for a media room I think we all can agree with the need for subs. He goes on to point out that for music listening he is not a big fan of subs. There can be all kinds of issues with integrating subs with your main speakers and particularly if you are overlapping them with your main speakers. Not sure I agree that a 5' cone will produce enough bass as air must be moved but in my opinion its not.

My most recent experience was with Martin Logan Summit X's and Descent i subs. I played around and played around and although I liked the added bottom end just was not happy with the results. Eventually moved on to the CLX and the newer 212 subs.

First off with the CLX there is no overlapping with the bass which I think is significant on its own. Add to that the custom cross over that ML supplies and then the PBK kit for the sub all that makes a world of difference. I can't say enough how the PBK kit has improved the bass. When you really think of it without some type of correction to your room you are not going to have stellar results. The other couple of things that help is go with two subs instead of one that does make a difference and also get the phase set correctly. Setting the correct phase has always been a mystery to me but once I found a method that made sense to me and applied it boy does it work. Also good room treatments are a must for good bass. I was surprised at the rear wall how much that made a difference.

Lastly is the volume to set the subs at. That I agree is a very time consuming task and as this progressed I moved the knob like a micrometer.

I will always prefer no sub for music, hence why I try to find a speaker that can reproduce a large frequency range.

Agree, if your speaker is designed right you shouldn't need a sub for music. But if you decide to go in that direction anyway then using an electronic crossover and a sub from the same manufacturer as the speaker can ensure proper phase between both the speaker and the sub and avoid potential bass frequency cancellation.

Bill, again, here is where we disagree.......... while a given 'full range' speaker may very well have the ability to produce into the 'sub' range it in no way guarantees to do so correctly given all the different room configuration possibilities. This is where a sub, or preferably two, properly placed will produce the 'best' lower octave(s)

The word "need" in these discussions always makes me laugh (at myself as well as the writer). We shouldn't "need" hi-fis that costs tens of thousands of dollars. But we do, and in that context, a well-integrated sub is a great value.
