Von Schweikert Research VR-4 Loudspeakers Review
June 7, 2020 § Leave a comment
“Play most any recording taken from a concert hall or other large acoustic space and you will “feel” the pressurizing of the room with these speakers. It’s amazing how much ultra-low low bass information there is on many of these recordings and how much that information enhances the illusion of your room being that same concert hall. There is a down side, though. It can get a little disconcerting when you can plainly hear the rumblings of the air ventilation system or the traffic outside the recording site. I hear way too much of this on Chesky’s Johnny Frigo with Bucky and John Pizzarelli and the other recordings made at the RCA Studio “A” site in New York City.
Another down side is that a speaker that goes this low with real authority, will excite room resonances and standing wave problems much more than speakers that don’t move as much air or that have limited range. I don’t have resonance problems in my “audio bunker,” my room being underground with concrete under the floor and on all four walls, but I do have a standing wave problem at about 34 and 37Hz due to the long straight and diagonal lengths of my room. With the Wilsons, they’re heard as only minor peaks—with the VR-4s, they’re quite a bit more prominent. Not to worry though, the problem is nicely solved with a few of ASC’s 20″ tube traps or some of Tyll Hertsen’s (Mr. Headroom’s) home brew frequency specific cancellation tubes. Let’s face it, you have to pay your dues if you want killer bass with no peaks.”
