Add a subwoofer to Von Schweikert 4Srs?

I feel that adding Subs to full range speakers improve even the best speakers. The reason I believe it helps is because good subs have room correction software that corrects room irregularities. They are also designed to work with their own build in amp. By being in a separate enclosure from the main speakers, room placement can also help to enable maximum output without distortion. The best speaker placementfor the low frequencies maynot be the optimumfor the highs. The more full range your speakers are the better they mate to subs. The fuller the base the better the midrange sounds. Check out these posts:
Is two Subs better than One & Sub. with full range speakers ?
I do not like adding complete electronic room correction unless I was only using digital signals. Placing more electronics in the path to my main speakers concerns me.
I use two Velodyne DD 15's with my Wilson 6. After seeing how much improvement the subs made to the mid and high frequencies, I decided to add super tweeters to my system. It also helped but not as much as the subwoofers. But placing them behind the speaker plane and closer to the midline increased the sound stage and individuality of each instrument.

More often than not the best placement for your mains is not great for bass. In my room full range speakers just don't deliver the bass I crave in my listening position. I have an older pair of VS VR4 MKII and now a pair of Aerial 9's and neither one can deliver satisfying bass in the optimal location for imaging and soundstage. Now if I were to move them for the best bass response the bass improves greatly but everything else suffers. I know that both of these speakers can deliver great bass in the right room, unfortunately I don't have that room and neither do you.

The best sub I have ever owned is the JL Audio Fathom F113. If you get a pair of these or even a pair of the F112 you will be set, probably forever. The first sub I have ever owned that can accurately convey the most subtle bass notes and I could actually describe as articulate. I have had the velodynes, Revel's, M&K, SVS, Von Schweikert and the list goes on in subwoofers but the JL Audio sub just kills for music.

Good luck.

it could be your room or speaker location. check out the speaker location calculations from cardas and others. i have used rel subwoofers with very good results with totem speakers.

You're welcome to try my Rel Storm, but I find it hard to believe that you Sr's fall short of bass.

I'll offer another comment reinforcing the room/placement influence. I have a pair of VR4 GenIII's (I bought them from Driver) in a dedicated multi-media room. Before I bought them I was doing research, and spoke on the phone with Albert Von Schweikert about them vs the VR4 JR. Although he raved about the merits of the VR4 GenIII, his one caution to me is they may be to boomy in my room (14x20x8'). My experience has been the opposite - the bass is weak vs what I expected, and what it is in my other larger(and irregular shaped) room.

I also have Totem Mani-2s that I run with a Rel Storm III, which I run normally in the larger room, but have swapped with the VR4's. It's easier to place the Storm to counter the room influence what it is the VR4's, but it still take some doing to place the Storm for optimum bass. There's something about my room acoustics that I need to address one of these days (just been too lazy).
