Got in my LSi7's last friday and was trying to decide where to mount them. The WAF was pretty low mounting anything larger than the RM series speakers I have now as surrounds.
I decided it had to be done and decided to try and pull off the wood sides from the LSi's I just got to make for a slimmer profile mounting them to the wall. (I am currently planning to use the wall bracket built into the lsi7)
I have called Polk CS before about this and they thought it would work if I used a wide implment to pry it off with and took my time. The person I spoke with then thought they would still sound very good (like LSi's should) even with the wood removed. (it is still 3/4 mdf with internal bracing - I figure that is all most subwoofers have so I shouldn't have much resonance problems from a 5-1/4 woofer crossed over at 80hz)
I called Polk CS again just before I started to pull it off to get their reassurances again before I start and spoke with a different CS rep. The story I got this time was the old series (what I have) used double sided tape to attach the wood, the new series uses glue and the sides will not come off. Even though I have the old series, he still STRONGLY recommended that I not try to remove the sides as he has seen the finish pulled off the speaker due to the strength of the tape used.
So much for assurances - Since I will not be able to mount these to the walls in their current state without alot of greif from the wife, I decided to forge ahead. I wrapped a 3" putty knife in an old t-shirt (now shredded) and started to work the putty knife into the corner of the side/speaker. I felt it give way and started working the putty knife around the speaker working it in about 1/4 inch to help loosen the hold of the tape.
When I got back to my starting corner, I pushed the putty knife inabout 1" and pulled it back out. (part of the shirt stuck and tore under the wood) I worked the knife in and out about 2/3 of the way around the speaker before the side was loose enough to just pull away.
The entire side is gloss black as i had hoped. There are no holes in the sides (also as I had hoped)
I worked off the other side the same way and cleaned up the mess. I will post some pics when I get home from work tonight, but let me say, Polk should offer these without sides as an option for surround mounting. It looks absolutely fantastic all in gloss black with the slimmer profile.
More with pics later - I have to get back to work.....
