Thanks RG.

I have posted at that forum. It's hard to believe that I cannot find any collaboration between Advent, or any info on any Sunfire 15" sub that resembles this sub.

I will try to contact the Sunfire company Monday, and hope they can shed some light on this.

I called Sunfire this morning. This Advent sub was a one-time collaboration between Sunfire and Advent and Sunfire had no information on the specs for this sub.. Sunfire told me to call Advent.

I called Advent (now under parent company Audiovox) and they said they hadn't retained specs on the older speakers. No more information can be found out unless somone out there has this same sub and manual....etc.

Great sounding sub though!

I copied and pasted the same posts here/there and my posts and account were deleted at that forum without explanation.

Thanks anyway.

The webmaster notified me that they had changed servers yesterday. This had something to do with my posts and membership not being available for awhile. Maybe DNS changes, maybe something else.

Anyway, everything is back as it should be. And, I apologize for giving wrongful information (even though it was not wrongful info at the time )

A search on Yahoo today has revealed more info about this Sub.

Apparently it is a Advent AV550S and has these specs.
