From the datasheets, it would appear to me that the FW305 would work very well in either a three π bass-reflex speaker or a six π cornerhorn speaker. The obvious advantage of the bass-reflex model is that placement is not as critical, so the speaker can be used in more environments. But the cornerhorn has some properties that make it perform better, giving better bass response and usually more uniform room coverage as well.If it were me, I would probably give the π cornerhorn a try if I had two good corners. The rising response of the FW305 will make it work pretty well in a two-way configuration, which makes the loudspeaker very attractive since there are no exposed drivers. The tweeter is forward facing, but when mounted on a wood horn, becomes an aesthetically pleasant and interesting piece. The π cornerhorn sounds very good in this configuration too. Or you can run the system in a more conventional three-way configuration, and use something like one of the Fostex full-range drivers and a super-tweeter mounted in the front baffle. Looks to me like either of these approaches would be very promising.
