Full range in Norh 5.1's
 
I've just got myself a T-Amp which I'm in the process of improving, but my Norh 5.1's (with their 87 dB SPL) aren't exactly a great match... Thing is, I love their looks, and I was wondering whether anyone thought it might be worth swopping the mid/bass and tweeter for a fairly inexpensive full range driver (maybe a FE166E)? Otherwise, any ideas for a fairly easy enclosure to house something similar?

Thank you.

If you could figure out the internal volume, and port dimensions that would be the first step.

According to their website http://www.norh.com/info/specs.html the internal volume is 13 litres. I haven't measured the port - I'll have a look tonight.

I am completely new to speaker design, so please excuse me if this is painfully obvious. Norh claim that the 5.1's begin to roll off at 55Hz and are down 10dB at 45Hz http://www.norh.com/products/norh5/index.html . Is that purely a function of their volume and port dimensions, or a combination of that and the drivers used? Fostex recommends an internal volume of 15litres for a BR enclosure, so the Norh's 13litres is a little on the small side. However, I'm not sure if you could class the Norhs as a BR enclosure.
