Completely different model than the later L100T floor stander towers ...
Gonna need a completely different crossover for a slot tweeter in there ...
And it will kill the resale for the L100s which ARE popular ...
I know this thread was ages old but I finally refurbed a pair of l100T3's I had and you are right. They do sound really, really good without the 2405 (although working on those tweeters stinks--i broke the lead wire changing out the foam pads--the magnet was actually waxed to the rest of the housing and it was frustrating and split and I had to solder in a single speaker wire thread). Either way they are fixed and working now. And they sound great. Really airy highs. Solid but controlled bass thump. Really impressive. I had been listening to some Infinity RS6B's before and they seem like some sort of sad joke now.
