Add a subwoofer to Von Schweikert 4Srs?

Thank you all for the advice. Now that it's the weekend I can try a few of your suggestions before actually trying a sub. First off, on the issue of speaker placement and room acoustics, I've been less than thorough at looking at that. We are in the midst of a minor remodeling project (old house...new ceilings and floor sanding and refinishing) and in doing so the re-arrangement has temoparily changed a few things:-there is half the furniture in the room there usually is -rugs I had on the walls behind the speakers are on the floor, under the speakers (at my wife's request "don't scratch the floors!") - I slid the speakers further out into the room (why not...no furniture to bump into). Basically, most everything has changed acoustically...though the mids and highs are currently glorious in my opinion. I just removed a good chunk of the Dacron from the speaker ports and slid the speakers back about 12 inches towards the rear wall...difference heard already. From a system perspective, concurrent with the housework I sent sent my Spectron amp in for an upgrade (goodbye 600 WPC) and pulled in my NuForce 9SEs (180WPC)...duhhhh...gee, that could make a difference. So...no final verdict forthcoming in the near future, but I hope to report back later. Say, Inhisservice, about the placement of the Dacron, are you saying not to leave it in the port...the tube part...but push it to the very back of the cabinet or take it out entirely?

Yes if you stuff the port you will give Albert Von Schweikert a heart attack! Just kidding. But the speaker is not designed to have the port stuffed only the cabinet. You can also take some of the Dacron out from behind the drivers by unscrewing the drivers. With the Spectron and a little less Dacron the VR4sr should be able to cause an earthquake.

Blessings, Bob

Aside from adjusting the innards for more bass (Albert can offer excellent advice there, instead of guessing), what I found is that just by moving my speakers a little closer to the back wall/corners, I picked up all the bass I need or could ever want. I found that as my VR-7's have continued to break in, the bass has also improved.

I own Senior Mark II. Bass was not so great when they where first hooked up. I had them in a large room with hardwood floors with conventional wood framing. However they improved greatly with breakin and I then purchased a pair of Sound Anchor bases which really changed them tremendously. Know they shake the room. Depending on the room placement and more importantly your floor construction the base can be seriously compromised.

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.
