Vandersteen 3A Sigs vs Klipsch Forte III


I'd like to get input on a comparison of both of these speakers. I have not heard them. No dealers in my area. I realize it may be an apples to oranges match up to many but want to hear the pros and cons of both. Haters welcome!!  I'll be driving them with a Mac 6200 integrated. 75w into 8 ohms and 100w into 4 ohms. Room is 27x18x10h. I listen to all music. Some vinyl. Appreciate moderate base, clarity in vocals, imaging, and like the speakers to "disappear".  Thoughts?

Have you or roxy even heard the Forte III

Yes I owned them for 4 mts got them cheap, as they were a good turnaround to make money on. A friend owned the older version, bass wasn’t as good/low on them.

Since the spatial info is encoded in the signal, somebody walk me thru the physics of how a big baffle improves the image ?
you do get the bounce off the panel and the back wall is 100% distortion....
but have at it, math gets extra credit
the same applies to focusing energy with a horn, ain’t nothing free.....
remember, I own horns, listen to them every day, I can assure you depth of image is not on my list of things they do well....

i will I’ll accept the homework assignment to go in and put a constrained layer damping treatment on the horn body,

No it is not 100% distortion because recordings are made, mixed and mastered to be played over a loudspeaker in some kind of room except lousy recordings that are made to be played in a car although I am not sure that is common practice in the industry today.

Someone mentioned somewhere, that they put a dampening substance inside the horn throat to reduce coloration or resonance. I highly recommend against that. It should all be from the exterior of the horn.

No math required. In my particular experience, it's very easy to hear. I'm not saying wide baffles are inherently better at imaging. I'm sure the opposite is often true, but my experience tells me it's not a universal rule. Some of the best speakers I've heard, regardless of price, have massive baffles. Anyway, I agree that in the case of Klipsch Heritage speakers, great imaging isn't exactly their forte.
