Im a little confused myself.
both models are sold in paris.
one is sold as a "stereo pair"
the other is sold as a "matched pair"
??
this is what Doug Oade told me yesterday.
Any way, i know the TL-II is the one w/the emphasis in the high end and the B-ULS is the straight one, and the pair I want.
The more I think about them, the more sure I am that they are *the one* for me. You can run any stereo configuration with them, from M-S to 20' spacked omnis. Very versitile! They will keep me busy with all of these options!
