I think some of you might be interested in John Crabbe's concrete 25Hz basshorn.

hi wayne,

hmmn can't get a bigger file size in the yahoo photo album so can either e-mail to someone who can host them or put them in a folder eveyone can download from kazaa.

interesting that the article alludes to an even bigger, less compromised, underfloor horn.

just might build these one day as the build doesn't look hard and they model well in mcbean with a fane studio 15 i bought for 25.00 sterling

by the way that karlson project i did with altec 806/811's , le5's /edgarmid and evm15ls ended up sounding best as a two way crossed at 800, pretty much like you said it would

thanks

gazza
