What are those anyway Dave, around 12' wide or so would be my guess? Bet the wife'd love those in the lounge.

There's no room for Ruth in Dave's lounge. She has her own areas and one of them is under the same poly, behind the right speaker.

The posts holding the deck up are 12' apart so the baffle would be closer to 16' wide and 1.2 m tall IIRC.

I decided to try damping the speaker frame (as suggested by Omega) so back down to Wal-Mart I went. Came home with several packages of "Feltac" polyester furniture protector strips (1"W x .5"H x 58"L).

A few hours and a whole bunch of trimming and cutting later, I ended up with what you see in the attached picture. Definitely made a difference in balancing out the sound more to my liking. The key part of the damping (IMHO) is shown as "A" in the picture. There's about a 3/8" metal groove between the speaker frame and spider that just can't be doing anything good for the sound. "B" and "C" are probably key as well. I wish I had an RTA!!!!

Here's a link to what the Horn Shoppe is doing with their latest and greatest Fostex:
Horn Shoppe 126E mods

On a side note, I have become very aware of box resonances when listening to "box" type speakers nows, including our floorstanders. I went over to a buddies last night to listed to his new 2-way mini-monitors with CSS WR125 drivers and was quite disturbed by the resonance (otherwise the speaker did some really nice things).

Now if only those drivers were waterproof, Dave wouldn't have to worry about fitting them in the living room.

We first listened to them at my place many months earlier, and with a diagonal room placement, there wasn't enough space between the panels for me to scoot behind. (Dave - you still have those photo's?)

Tom: there's a quality to the bass response on an open baffle that's hard to describe, but the smile is easy to detect. Even the FR125/WR125's are amazing in this configuration - although sensitivity and Xmax limitations could be a problem.

eLarson,

You know, I did just get a digital camera, finally. Supposed I need to learn how to post a photo and do just that. There are some disturbing gaps in my technogeekdom . . .

Regarding the Hornshoppe mods; What's with the non-circular driver cutouts. I guess hillbillies can't work a circle jig.

This is a close up of the driver. You can almost make out the OfficeMax logo on that center binder clip at the top.
