Add a subwoofer to Von Schweikert 4Srs?

Mancuso: I know what you mean about break-in time with Von Schweikerts...can't be stressed enough. Sounds like your floor construction is similar to mine. I'm going to guess your Sound Anchor bases (versus my outriggers NOT coupled to the floor) are a better tweak to enhance bass performance. In recent weeks I have been experimenting with monitor speakers (Sonus Faber Concertos and Usher BE 718s) with the addition of a REL Storm III sub. The monitor/sub combo has great coverage from top to bottom. When I run the sub with the Seniors, it adds a little less than half an octave of depth...a very satisfying arrangement. Regardless of what I do with the monitors, the Storm sub will be staying.

I added a Velodyne DD-15 sub to my VR-7's 2 wks ago and this weekend during RMAF Albert was kind enough to come over and dial in both the speakers and the sub to my room. Its a sonically difficult room and Albert was able to make those 7's sing!! I was amazed at how quickly he overcame several room anomalies, as well as how great my system now sounds. Albert's skill and knowledge are very impressive, plus he's a nice guy as well.

I kinda know how you feel Mdrummer01.
I have a pair of B&W N802's driven by 2 Linn Klout Amps that I believe need a little help from a sub, but told I'm crazy too.
The boss (wife) hasn't allowed me to make that purchase yet.

you can buy the biggest sub and the biggest speakers and if you put them in the wrong location in the room, you will not get the bass you are looking for. i have heard systems that when you sit down, there is no low end. when you stand up and stand behind the chair you just sat in, the bass was overwhelming. most of the rooms at RMAF had positioned their speakers many feet into the room and they still provided all the bass you would ever want plus the imaging and spaciousness that you get from pulling them out into the room.
