Does anyone know the woofer model used in the sub woofer B-380. I seem to recall that it was a 15 inch 136H/2235. I have a B-460 and a friend wants to make a smaller version. He has 166s with 122s so I don't think using the 121 from the L-212 cube will accomplish much.
2235h !!!
If you were asking about swapping-in a different LF into the L166, while most here aren't big fans of these maneuvers :scold:, I was thinking the 128H (my favorite of the 12-in line...) could be considered. I LOVE what it brought to my 4312's :eek:, but found this on the L166 tech sheet:
Maybe Giskard knows why it is "only as last resort"... :confused:
Thanks!
No he wasn't going to switch out the 122as he just wanted a separate sub for theater surround. BTW in the nothing better to do category I switched the 122a in a pair of L-65s to 128s from L-150s and thought it did not sound better. Not really fair comparison since they are in a shop on a shelf. Settle down, I know the crossovers/ cabinet tuning/ speaker placement have effect.
Well ok, I guess I'll refrain from harping on the merits of the 121, especially when used in multiples.Quote:

Yeah, the response of the 128H-1 is "all wrong" for the L166 and L166A filters. It's all fixable though.Quote:

IIRC, the 128H has too high broadband efficiency, too much top end and not enough bottom end, to be substituted for a 122A... right?
(Note, that all of these things change, when you add the 10 gram mass ring, to take the mass from 90 grams (128H) to 100 grams (122A), total moving mass... :cool: )
