Replacement woofer drivers for the Acoustat Spectra 1100 speaker by Dave Ayers (August 16, 2005)

Liam (November 20, 2008): I have obtained specifications from Rockford for both the 4 ohm and 8 ohm drivers that were used by Rockford in the Spectra 11 speakers.

The specifications are dated Oct 3, 1996. it's possible that different drivers may have been used at other times.

Contrary to other comments I believe that at some period these same drivers were also used in the Spectra 1100 speakers. The drivers in my Spectra 11's look identical (same magnet size , etc) to the photos of David Ayer's drivers).

If anyone would like a copy of these specifications I am happy to email the pdf.
