I lucked into a pair of inexpensive LX5. A couple of thoughts:
Specs for tweeter if purchased from Radio Shack as a replacement, it came with a crossover. I have to assume the tweeter taken from the LX5 may have a different crossover?
- I was thinking of building a pair of stand-alone super tweeters to place on top of my Pioneer bookshelves. Can I use the lineaum for that supertweeter project? or
- I could also build a new box for a woofer, and just bi-amp the new box-woofer and the lineaum, that way I don't even need a crossover, do I? Just some filter on both drivers. If I go this route, I would need to design a woofer to watch the efficiency of that lineaum which is unknown... although the LX5 had low efficiency 81.5db (see below). Not sure if the low efficiency was due to the tweeter?

Specs for the LX5:
The original woofer was pretty bad, but these Hi-Vi L5-8R are great and fit like a glove. About 5 years ago I replaced these in a friend's LX5 when they were $25 each. Now they're over $40...

Bear in mind that the frequency response of this lineaum tweeter does not extend high enough to be officially classed as a super tweeter.
This lineaum tweeter is described in this review of the RadioShack Optimus Pro LX5: https://www.stereophile.com/standloudspeakers/695ratshack/
In the review, it is said that the bi-directional tweeter's radiation to the rear should produce an enhanced feeling of "airiness" to the speaker's sound in all but the very deadest rooms.
The crossover of the LX5 is minimal - an iron-cored inductor in series with the woofer and a 6.2µF plastic film capacitor in series with the tweeter.
