so now explain what we are seeing in the picture here. It looks like a very short and small horn lens on the bass driver and I am assuming that the upper three devices are in a dipole configuration from just looking. Is there a scientific reason for the upper baffles shape or is that just for looks? Why so much more reflective surface above the tweeter than on the sides? Very unusual to say the least.

The bass config is used to cancel forces on the baffle (it's not a lens). The upper section is such that each driver crosses over to a smaller one before starting to beam. This, according to SL, makes it behave as a point source. The baffle shape is specific to the design.

I was at BAF and heard it. Nothing short of spectacular. Timbre and tone were spot on, and the imaging was wide and very deep. Surprisingly, it was capable of quite high SPLs. I also attended RMAF, and the LX521 was far, far ahead of anything there.

FYI, SL has updated his website with an excellent description of the LX521 evolution.

The looks actually grow on me!

It should be something that takes 1hr to do (if you have the dipole subs already). Should be great fun and to find out the polar response of this approach.

I was exhibiting in SL's room at Burning Amp so I got to hear his speakers quite often during the day. Several times I was honestly quite amazed at the quality of sound reproduction!

I have had open baffle and W-frame projects on the back burner for awhile, often taking new directions as I consider changes in drivers, layout, etc. Now that I have heard SL's system I am hoping to finally get my own efforts off the ground and see what I can come up with, using drivers that are worth about 10% of the ones in the LX521 (since that's about what I can afford!).

The subs not bad.. but the top is like a cardboard vase prop.

(..JohnK's recent offering has similar aesthetic problems, sort of a stubby wooden Aerius without the front arc - still, better than it's predecessor.)

As for clean modern design, both could take more than few "lessons" from your recent effort. ;)

They are loudspeakers. They are designed to be listened to. If you don't like "looking" at speakers you can:

a) put a grill around them

b) get some nice "in-ceiling" units disguised to look like smoke detectors.

A bit more than that, you'll find . . . at least to get it right . . . :rolleyes:

But you knew that . . . ;)
