Transmission line speakers!

On further review of the infinity marketing material that led me to think the monitor ilia is transmission line - it actually says that they “pack the other Enclosure with uniquely configured material that further damps the woofer and creates a transmission line load”.

I think the real magic is in the woofer itself which has damping material applied to the cone which stiffens it.  
 

they still produce glorious deep, deep bass, however it’s done.

tomic601,

Thanks for the correction, my mistake. Yes, it was the B-139.

My Vandersteen 1C’s are transmission line. The ‘port’ is a wide thin opening at the rear bottom. Now used in my bedroom system. Was laying in bed streaming last night before going to sleep, and never ceases to amaze the *quality* of bass those speakers are capable of. Are they as good as my 2CE Sigs or Treo’s in quantity of bass? No, but pretty good for what they are.

tomic601....and Beano won’t stop it!

Real drag for us refried fans...having to stay downwind to download, degauss, denigrate the local atmosphere....not to mention the potential of cheek chunks...

(I know... "Too much information, runnin’ through my head..." Thanks, Sting....*G*)

*sigh* 6’o1, half dozen of the other.... ;)

@reubent , never heard or heard of the Clements RT7’s. but a quick drill-about brought up a look@.....👍 Taller ribbon versions of that sort seem to present a nice stage, I’ve a smaller bookshelf pair that mate nicely with the home flat screen. Part of a small Philips set bought to ’fill in the blank’ awhile back.

One CN vendor (NewformResearch.com) has tweaked my interest with theirs, but never pulled the itchy trigger of mine to try. Never read any comments here, but would expect the HF drivers to respond nicely. That, and not being a dipole would be an attraction for the room(s) not suited for such.... If any have any thoughts upon, would be of interest perhaps...

Seems to be TL cabs beneath, but could be wrong.....*horrors* Me, Wrong?!

Yeah, weakly....*L*

My Shahinian's were transmission line, as were my TDLs. I think PWK's folded horn was an extension of the principal.
