Avantgarde Trio replacing Dunlavy SC-V?


Hi folks, I have big problems with room acoustics. In my listening room there are a few very nasty room modes and I can't get rid of them. My current speakers are Dunlavy SC-Vs (sealed d'Appolito design). I'm contemplating to replace them with designs with less bass output capability, like electrostats or... horns! In the later case the Avantgarde Trios come to mind. Maybe I could do a set up without subwoofer(s), so there would be far less bass (I think in case of the AG, there is a natural bass roll off from 100Hz, which should be better for my room). What do you think? I'm aware I'm comparing apples with pears, but do you think the AG Trios could be the solution? Thank you in advance.

I have the same bass node problems in my room (18x13) with SoundLab speakers. A change to electrostatics will not guarantee that your problem will go away. I have a huge peak (13db) at 30 hz and two smaller peaks (6-8db) at 110hz and 250 hz. All the shuffling of speakers and other things in the room only reduced these by a few db at best.

Unfortunately ASC tube traps did not reduce these bass peaks like I had expected. With 5 ASC columns, 6 and 7 feet tall, 11", 13" and 16" diameters, the improvements in the clarity of mids and trebles was very impressive and unexpected...but no luck with the bass.

I then tried a Rives Audio Parc and this allowed me to bring down all 3 peaks; the result was mightily impressive. There was much more clarity again in the mids especially due to the bass no longer being so overpowering. The unfortunate side-effect was a reduction in dynamic contrasts due to the added box and additional set of ICs in the chain.

There is a company here in the Minneapolis metro area that makes acoustic panels with tuneable cavities. I understand these work incredibly well to control bass nodes. This is the next thing I investigate compared to the Parc solution. Send me an email and I will pass on the site to you once I find the brochure at home.
