[6pack] 6pack Digest, Vol 2, Issue 401

[John VanNorman]

I found that once I installed the speakers (securing them to the pads
with four screws going through the speaker's mounting holes and the
pads and then secured on the backside with nuts), the kidney pads were
pretty solid.  But without the speakers in place, yeah, they are
pretty flimsy.

Also, I used standard size 6 "speakers and had no depth problems.

However, you are absolutely right on hearing them.  With the open
backs, there is no enclosed air (like on a stereo speaker, door panel,
or trunk), so the sound you get isn't that great.  I ended up building
my own speaker box for the shelf.
