One can only expect so much from a Walsh, even though the lower cone has a radiating surface similar to a 10" dia. conventional speaker. Since they are DIY, I don't ask of them to crack sheetrock. *L*
LL Cool J's Mama Said Knock You Out is on one of my playlists and they deliver just fine. ;)
I made a smaller pair that's in my office and serve as monitors for the 'puter I post at, trying out how 'acoustic suspension' works with the larger drivers. I occasionally post what I'm listening to or what the ongoing thread reminds me of; likely to the dismay of the gathered....*L*
They can handle 'volume to 11' on a small Phillips integrated without clip, but it's only ~10wpc so no big strain but loud enough. *G* I eq them with the 'puters' Realtek program to punch the highs since the 'tweet cones are dinky....another ongoing DIY affair....
