stephendunn,

Sure,,,,no probem.....but then you do not get to tune your system with different flavors of speaker wire. And, as debjit said....experimenting with wire is made very hard.  If you have mono blocks then absolutely you can mount them right behind the speaker and use the wire coming out and hook it right to your amp posts...using the wire tinned (no spade/banana....all connectors suck)..  

debjit_g,

Most speaker wires are not shielded.

Direct wiring does have benefits, I’ve tried. Ricevs, let us know if you start that OB thread.

David and other owners,

Have you had a look inside the box?  I saw a photo once that showed it to be a box lined with foam panels.  But, the name suggests it is a tapered quarter wave tube loading arrangement which would include a slanted piece of wood creating two tapered chambers.  Is this the configuration? 

It might be play around with those terrific drivers and either a foam-lined tube with a vent on the bottom or a similar TQWT alignment would be not that hard to build.
