funny thing is that it seems that I can't be -ever - surprised by Papa's ideas ......

OK - with ideas - yes , but having him around again with new things , is somehow usual .....

Sell it and build a dedicated listening room. ;)

Being single can suck sometimes, but sometimes it's alright!

Interesting idea. Of course i am wondering if size of slot is optimal and if there are even ways of figuring it out? I also can't help but wonder how two 15" drivers per baffle would sound simply facing forward compared to the slotted system.

I wonder if the speaker can be slimmed down by bending the sides of those wide baffles? May not help the Lowther's response but would it hurt the 'bass system's' response? I can picture 8 or more woofers from floor to ceiling in corners filling a room with incredible bass while maintaining a slim footprint.

Thanks for sharing. It's probably a good idea. Hopefully others will wrap their minds around this and move the idea forward.

I need coffee!

It has already been done:

The Visaton Grand Orgue is simply a stack of Ripoles with a short line array of FR speakers in front of it.

Is this why Nelson bought all those cheap 8" woofers at P.E.?

hi,
I looked at the amt-3 from Nelsons build,got a question? A picture from the front of a built speaker would tell me ,but is there one slot for each 2 facing drivers ? like 2 drivers in one slot,so you have 3 slots?or is there just one big slot 2.25"X30, I don't know if it would matter too much,the pressure comes out of the slot when they push and back in when it pulls,Thanks!!!!!
