Default 15's with low FS wanted!

Anybody have any used 15" woofers (8 Ohms) with an FS in the teens or low 20's?

P.S. Still hunting an Audax tmo25f1 tweeter if anyone has any!

You want a matching pair don't you Bill??

Second hand Dayton Classic 15 ?? and add mass until Fs drops to desired frequency, put up with the drop in SPL & the sag can be fixed by rotating every year or two

Hi,
as you add mass the Q rises.
If the Q is already medium, say 0.3 to 0.4 then it will probably rise too high for a vented enclosure. A sealed enclosure already has a raised resonant frequency that has little dependency on Fs so you have little to gain.

In addition the efficiency/sensitivity falls with added mass.

if you are interested in a single, I have an Adire Tempest which is a 15" woofer with a low fs. This driver is as new and has not been run in yet.

Send me an email if interested.
