I also agree that the PBN Montana speaker is similar to the Dunlavy but a good bit better. I have owned the Dunlavy V so am very familiar with their sound. Have owned the PBN Montana EPS 2, and currently using the WAS 2. If you liked what you heard from the Dunlavy's you will LOVE what the Montana's do.
Any Large Acoustic Suspension Speakers Being Made?
I auditioned some Dunlavy SC-IVAs in the 90s. The sound was unlike anything I've heard before or since.
Was more like a video projector creating living sonic-images in the room.
The Dunlavys are a sealed box system. The front of the speaker is heavily felt damped (mids & tweets).
I'm also wondering about anything unusual about its crossover. I have to find out why these sounded so good!
The system: Audio Research VT-120 amp, ARC LS-2 pre, Theta DAC (pre-pro?), CEC Disk spinner, and Dunlavy wire. The room was about 25 * 25 with curtains on a glass wall and LPs on the rear wall. Power conditioning is unknown.
So I'm thinking it's either the acoustic suspension or a special crossover that made the difference.
Does anyone make large sealed box speakers anymore?
