I need to make tuff decision.
I need to to keep just one pair.
What should I keep, 2441,2450 or 2451?
My plan is to get Truextent Be diaphragm in future.

What horns do you have?? 1.5" vs 2.0" What's your best horn? I would also go for the most modern phase plug and compadibility with the Be diaphrams. For me I would choose a 2451 becasue I have Array Horns as an example.
Rob:)
Now I have 2" horns but I will make new one, probably JMCL, Tractrix or Yuichi A290, still not sure :(Quote:

Keep the 2451. The others have an exit of about 4 degrees. Most JMCL horns have an entry angle much larger, causing a diffraction where the angle changes.

at least the installer did not mention any difficulties,

:D
edit -- i'm using the 2440 motors on either 350Hz Edgars or some DAS (or McCauley???) acoustic lens clones -- hartsfield/serpentine lenses and a 2343 shaped clone horn
funny :)
I attacked mine with an exacto knife -after- talking to the Truextent guys ;)
(bit of excess VC adhesive was making things... difficult... IIRC, those type of
issues have been resolved).
For what it's worth, they went into 2450SL motors on 2352 horns.
How is that working out for you? What is your LF?Quote:

Any idea how the 2352 compares to the Yuichi A-290?Quote:

I wonder is it "better sounding", two 15-inch with ultra LF and LF network combination based on the 'mutual coupling' as in DD66000, or 18-inch with 10 (or 12 inch) , that are much less 'overlapped' frequency region (as 4345, ....), but I believe the results would be 'delivered' to us.....Quote:

I'm working on putting a system together with 2 2226J's in there own cabs with a 2446/Be on Yuichi A290 clone. I'm thinking 750 hz crossover and adding a extra coil for the helper LF driver like the Everest somewhat.
