What Do You Think . . . and How Does It Work?


While watching vids on YouTube, I came across this pipe speaker design from a Dr. Linkwitz (see below).   The sound of this speaker is said to be impressive.  I was wondering if you know about this, how it works and what you think of this speaker design.  Also, what do you think would be the best room placement for such a speaker, and would you be tempted to build them?

i heard these speakers at AXPONA a few years ago.  it was in the madisound room that sells these kits online.  
very incredible deal for the $230 for the kit less the PVC piping.  in this case they used minidsp for the active crossovers.  
sound was deep, rich and had very good bass impact. not the last word in midrange transparency though.  
I’m sorry, and I’m not trying to be a jerk, but they’re pretty dang ugly in my humble opinion.  You asked... I answered!
Didn't HSU make home subs from cylindrical cardboard concrete forms back in the day?
@stereo5 , lil better everyday!  Thanks for asking.  
@bob540, I’ve been somewhat obsessing over speaker kits lately. I’ll send over my favorites here in a sec...
