Agreed, last I heard from Charlie he was becoming convinced dipole down to 20Hz was unnecessary and was heading off to experiment with sealed sub. I think the other end of the scale is interesting too, how late reflections at high frequency can relate to the size of the perceived space..... best to play and see what you like..

my LX521 will also have a sealed bass (down firing). I also intend to implement a passive Xover to the tweeter section so the speakers could be bi-amped. It will probably be the only LX521 driven by a tube amp on top :

Default Return to Horns

I've had my fun with the Van Halen planar dynamic hybrids, but was missing the transient snap of my horns.
Plundered my Onken cabinets, and am trying no baffle for now, as the Van Halens can be modded for a slob sub.
So far so good; the 2 Celestions are quite good without a baffle, as long as they're close together.
This pic was from this morning, prior to me mucking things up with wire.
I may post if I figure a way to do that neatly.
Maybe the easiest build I've ever done, and I think the no stain no oil no finish gets the steampunkish mancavd look I was aiming for.
Loving the exaggerated dynamics and colourations. The BG stuff is great, but horns are the fun date.

I did put the Neo 10s in a homemade horn once, maybe a year ago or so.
It didn't improve them much.

..bummer.

I was "picturing" something like this (with an active digital-delay for the compression or ring tweeter), where the JBL compression mid was replaced by the Neo 10:

My horn was much less elaborate.

It was about 12" deep, and went from 5" wide, to 3" wide, then flared to 23" wide.The intent was to use compression to load the membrane, and bolster the 300 to 1000hz range.
Don't allow my lack of skill in designing a horn deter you.

With this mode I can make different configurations.
The crossover is a nanoDigi with three Soekris DAC. The amps. Probably Pass diy.
Any suggestion of the public ?

Are you getting decent bass so close to the wall? Clean lower midrange?
