I've been finding the ideas of building a 3-way speaker around a high-efficent extended midrange driver very appealling. Stretch a midrange out on either end as far as possible, and supplement with a sub and super tweeter. I've started doing some research on what's available in midrange pro-drivers, but believe that full-range drivers such as Fostex can also be an excellent choice.Problem is, Fostex has a lot of drivers, and their websites do not do a very good job in explaining the differences between all their lines. Would anyone on this board familiar with the Fostex line be able to give me a head-start?
I'm not too concern about digging deep into the bass region, so I don't think I need anything complicated like TLine for backloaded horns. Just something simple like closed-box or BR. A range of 100Hz to 5KHz would be nice.
From what I can gather, the Sigma line is best suited for back-horns while the FF drivers are suited for BR. As for the FE drivers, I've seen these used in both configurations. What are their PS drivers like?
One last thing. There seems to be inconsistencies with the Qts specs of some of these drivers on the web. Posts in this forum indicated that FE drivers do well in BR due to their high Qtd, the the spec sheets on Fostex's site rates the Qtd quite low (less than 0.2).
thanks,
Gar.
