What would the dimensions be for the servo 8" woofers. I am interested in the c c dims between the mounting holes specifically. Thanks

PM or call Danny directly---he's the best source for that information.

The outside edge is 8.75"

The through hole needed is 7.5"

[bdp24]

Danny, I think Manolo wants the center-to-center hole spacing for mounting bolts.

Don't know if this helps, from the Rythmik site

*    Mounting: 8.78" (222.5mm) outer diameter and 9/64" (3.5mm)recess
*    Cutout: 7.56" (192mm); screw mounting pattern diameter: 208.5mm

Jay, where did you find the specs? I don't see them included with the GR OB woofer info in the driver section on the Rythmik site.

Down the page a ways where the 3 little  thumbnails are, you   have to seklect the  driver  you want the specs for, then   the  data below is shown  (not even sure selecting the driver changes any of the data, looks like maybe  jus the  thumbnails change).  The 1 ohm version is shown  there  so I'd imagine the   physical  maeasuments are the same,   I'm   sure Danny can confirm



Driver features
*    Light-weight paper cone with light weight foam surround for low insertia
*    Rigid 4 spoke cast aluminum basket
*    FEA designed aluminum short circuit ring to reduce 2nd order distortion
*    High linear excursion capability of 1" peak to peak (xmax)
*    High mechanical excursion capability 1.6" peak to peak (xmech) to reduce risk of bottoming
*    Very low inductance
*    Woven wire lead in the spider to prevent rattling during high excursion
*    Faston connectors for driver and sensing wires
*    Single 2.8 ohm voice coil
*    Mounting: 8.78" (222.5mm) outer diameter and 9/64" (3.5mm)recess
*    Cutout: 7.56" (192mm); screw mounting pattern diameter: 208.5mm
*    Two 3/4" stacked magnets for a total magnet height of 1-1/2"
*    Cutout: 7.56"
*    5" clearance in depth
*    250W RMS max power

Yes, the frames are the same.

[bdp24]

Ah yes, now I see them. Thanks Jay---Eric.
