What to do with Yamaha spkrs

jackinnj · 19th December 2006, 07:59 PM

Repaired some Yamaha 15" club speakers -- do to over-exersion the voice coils had become detached -- once repaired, the stats look like this:

fs 50.75
Qt 0.934
Vas 197.3 L
Sd 89000mm^2
BL 11.8

just put them into their original cabinets ? (27x20x12 inches).

When I see the high Q, I think of a large open baffle. Are the Yamaha's well made?

Hi,

OB's and clubs do not mix.

Put them in the original boxes, they will be fine.
No real bass mind you, but that was never the original design intention.
Generally this type of alignment has no BSC other than the highish Q alignment.
