Buy them, if you have room for them. That's a VERY good price.

They are NOT "Just boxes."

but i have heard they have no punch what so ever only rumble and also are very inefficient and the drivers blow with ease.....

Balderdash. They work very well and produce huge bass with very deep extension. I have four of these beasts - built them myself with 2245H drivers. Look at Zilch's thread for more info.

The enclosures are complex -- not an easy build. If you can purchase the enclosures at a reasonable price -- do so. You can get JBL 18 inch drivers on EBay -- sometimes for a very good price. The enclosures only consume a 30 inch square when placed on end....

Just look for a used BGW 750C or an HH V800 to power them -- you will be very pleased with the bass.

At full tilt, you may hit the "BROWN NOTE" heh heh heh

You need to look at the Theile-Small paramters for the Fane drivers...
THe 4688 is purpose designed for a specific JBL driver..and hope the TS paramters for the Fanes are close enough.

My 4688 clones differ significantly from the stock ones becuse I used JBL 2245H drivers instead of the 2241 (I think that are used in the stock 4688s)

Maybe Zilch can help on this one??
