I'm not sure what you mean by "blooming"? What does that mean technically? If you mean that it causes a sudden increase in dispersion at 1.4kHZ, then we're saying the same thing (?).
Hi Bob,
Yes that is what tweeter bloom referrs to. But there is more to it than just tweeter bloom.
They are mine ...
Thanks for the complement -- I am a big advocate of not "hiding" the principle architectural feature of an object -- to my eye, what was unique was the upper baffle in the LX521, so I wanted to emphasize it. Red is always a good bet with black. Here is what I posted on the ORION/LX521 forum ...
I can report that the LX521 leaves the ORION (all variants) and PLUTO "in the dust" (sadly, perhaps, but technology marches on....). There is a clarity and truthfulness to the midrange in the LX521 (long my pet peeve with the ORION, which improved with each X'over iteration) that is so natural and right that it is immediately clear we are dealing with a different caliber of transducer. Imaging specificity and micro-dynamics in the LX521 is significantly improved (high WOW factor) over the ORION -- hard to believe, but true.
The loudspeaker is straight forward and simple to build (as long as you have good tools) and the ASP is simpler than the ORION's ASP. Everything has been pared down to the essentials -- the LX521 demonstrates "transcendental" FFF (Form Follows Function) engineering.
It is a winner.

Well... well.. then *can* look really nice !!

Sure, there is nearly always more to complex technical relations. As I said, it is the primary reason or one of the primary reasons.But there is more to it than just tweeter bloom.
Bob, we are saying the same thing in relative terms but not in absolute.If you mean that it causes a sudden increase in dispersion at 1.4kHZ, then we're saying the same thing (?).
It is not the directionality of the 8" (too little off axis energy). It is extra (too much) off axis energy in the tweeter section. And it does not ocurr at 1.4KHz region but around 2KHz.
Charles, they look cool ! Somehow Ferrari or Formula 1 like

I'm sorry, as a Ferrari owner I have to object. Not exactly the same state of artistic design.
My 308:
An externally hosted image should be here but it was not working when we last tested it.
Not objecting to the speaker, just the comparison.
You've got the wrong number, John. Siegfried Linkwitz must have had the Ferrari 521 in mind - what else:

There can't be any doubt that the sharp contrast between the edges of this Sergio-Pininfarina-designed Ferrari 521 S Berlinetta Speciale from 1969 and the expressive curvature of that thing on top of the car have been the ultimate inspiration for his LX521.
Cool.
Never seen that before - the car that is.
(..dirty blond bent in that position with leopard Lycra - that I'm familiar with.)

Are you missing the smooth curves over the roof or the curvaceousness of the sculptured sides? What do you think the woman on top is suppose to represent, a wedge?
Technical aspects only, of course. Perfect dipole figure 8 perhaps? No excessive bloom in the top department for sure - compared to the late ORIONs.What do you think the woman on top is suppose to represent, a wedge?
She's probably produced a few of thoseWhat do you think the woman on top is suppose to represent, a wedge?
You want to know what is really funny? The red on the Note II is actually a Ferrari color, Rosso Barchetta. I had the pain laying around 'cause I was spraying some out to see what it looked like when I was considering buying an F355 last spring. Unfortunately the car didn't pan out.
The reflection of the light in the picture makes it look a lot redder than it actually is. It's more burgundy under natural light.

Great build indeed, and your review gave me the kick to build one/clone.
Would you mind sharing the color code/brand of that red? Really nice!!
Safety RED
I spray painted the upper baffles with the following:
1 coat Sealer [1lbs Shellac] (Brushed/Wiped "flooded' on)
[sand 220/320/600 Grit smooth]
2 coats RUSTOLIUM grey primer
[sand 320/600 Grit smooth]
3 coats RUSTOLIUM "SAFETY RED" Enamel
[sand 600 Grit smooth]
3 coats Clear Laquer
[sand 600 Grit smooth first two coats -- allow 24 dry time between coats]
