What percentage of audiophiles use a sub ?

LOL!!! No no. I wasn't trying to offend anyone or say you can't or that it's wrong. Forgive me for loving my two channels of joy. I just feel that adding a sub approaches the more is less philosophy. And I'm even taking cues from professionally installed with the top of the line products and sound isolation, room treatments....you name it. And I hated hearing the sub. It was so isolated from the rest of the music. I could hear where it was coming from even when it was turned down.

Now on the subject of sound wave propogation. Those very low frequencies will never develop in your listening field. So why bother trying to produce it? I'm not going to start in on the numbers game but if you have a sub and have some specs, do the math. I'm perfectly happy with the bass response out of my monitors. My 43Hz is plenty low. My buddy came over just earlier today for a listen and asked where the sub was at or if there were any other speakers. I told him "yer lookin at it." And the sad part is I only had the volume up 1/6th of the way.

And again, its just another speaker to add more distortion and I don't think the addition of more bass is congruent to the philosophy of resolution and clarity desired by hi-fi audio purists. Then again that is simply an opinion. If you are getting offended then take a deep breath, call me nuts, and move on. ;-)

I really love topics like these. So stimulating.

I Dynaudio monitors that do a fantastic job with an extended low end for their size.

Set up properly, they almost do it all but small speakers cannot move enough air to deliver a muscular low end as larger full range designs can. So I have to say they almost do it all, but do require a sub to really do it all to the extent of good full designs. All smaller monitors I have ever heard do, even Magico Minis.

For many, they do it all enough that it does not matter which is fine, but I have yet to hear small monitors that can compete with equally good full range speakers for delivering the oomph that some music requires.

Tigg,

Feel free to stop by (SoCal) and check the RTA in-room readout of a 20hz to 200hz sweep. You'll note that the system is flat to 25hz on axis at the listening chair. Could go lower, but no need for music. You'll also see that the system is +/- 2db below 125 hz - pretty much impossible IME without subs and/or DRC.

PS If you take a listen to the program material of your choice, you may not hear much below the 43hz you get on your system (very little music goes there) but you will hear the lack of the typical suckout at 80 hz (usually north of 10db) and the missing hump in the 1/2 octave above that (usually north of 10db,as well).

No offense taken at your post - just pointing out that the suggestion of upgraded speakers doesn't eliminate 1/4 wave cancellation, unless the speakers are in-wall, on wall, flush to the wall, and/or digitally corrected.

Incidentally,

You don't want to measure the distortion in the bass on your (or any other) monitor. I'd direct you to any of the subwoofer forums, but the results might make you queasy. Suffice to say that even specialized 8" drivers tend to struggle below 50hz at volume. The large cone (12",15",18"), drivers in the better subwoofers will typically produce about 1/10th the THD of the best 8" drivers at highish SPLs <50hz.

Pre-empting any comments re: "speed" in the bass, I'd personally look to group delay measurements (which tend to correllate with damping rather than driver size), but I'll acknowledge that some feel that these don't tell the whole story.

Mapman - "I have yet to hear small monitors that can compete with equally good full range speakers for delivering the oomph that some music requires."

No argument there. I love full range speakers, especially the Reference 3A. For an apartment dweller I just couldn't go full-range and found my monitors to be more than satisfying. But even then, with a full-range setup I still would not consider a sub. Again, that's just me. My car is a different story. I like it heavy and low and my JL 10W7 gets me just that. ;-) But then I'm not aiming for perfection in a mobile environment.
