eHey Neil
I don't know if anyone has built one yet, thought maybe BK wanted to be the first

Seriously, there is the 4 ohm version being offered on the Rythmik site so I'd imagine in a samll room paired with the LGK's, it should work very well
Danny or Brian (or anyone else for that matter) have you guys tried a single 8" in a small room ?
A couple more ?'s about the 8' drivers...
I assume 3 of the 16FR model in parallel can be run off one HX300 amp ?
How would 3 of them compare to a pair of 12's ?
I am still kicking aorund ideas of what I am going to pair with my OB7's but I am probably only going to be able to start with a single H frame and add a 2nd later.
