L200 Network Schematic...?

[dmtp]

What about a LE14A with the L200B cabinet and XO?

[Zilch]

L200(B) box is too big (4.9755 cuft. by my calcs) for LE14A.

BB6P says it wants 4 cuft. for "Extended bass," or 2 cuft. for "High Fidelity" (maximally flat).

Just use 2235H in L200B and concentrate on fixing the VHF.

In L200(A), the same, but close one of the ports with 4" plumbers' test plug for extended bass. Gotta move the Xover down to 800 Hz for that combo, tho, 'cause 2235H doesn't play very nice above 1 kHz..

Add cross-bracing inside the box to reduce LF resonances.

[There's MUCH more better stuff to do with LE14As, anyways.... ]

OK, I'll bite. What would you recommend doing with LE14A's? I happen to have a pair looking for a project.

That is the pic Zilch posted above!

1) There's the 240Tis, above, though I've never tried that. The "evolved" JBL three-way floor-stander; a Giskard favorite, as I recall.

2) They make very nice subs in Citation 7.4-size boxes (~3.4 cuft. @28 Hz).

3) Members Hamilton and John W have recently made L200T3 clone two-ways with biradial horns; a Zilch favorite. Reduce to 4425 size for "bookshelf."

4) I'm using them in small L55 boxes two-way with 2426H on $9.90 PT waveguides. BB6P says 2 cuft. @~32 Hz is optimally flat alignment for LE14A.

[Mine are now tuned a bit lower, ~30 Hz; 27.5 Hz was too low.]

5) Smaller still? Build S99 Hotrods using that same 90° x 50° PT waveguide and thread-on compression driver. I've tried 2416H-1, 2418H-1, and 2426H.

John W's project used 2344A horns; the 2342s in Hamilton's version and factory L200T3 are still available new from JBL:

LE14's probably the world's most versatile woofer, and among the best sounding -- lotsa good options....
