That speaker is designed mainly for paging and background music. It's often used with a transformer to utilize the 70/25v output off of a pa amp. You can remove the transformer and use a regular amp, but I wouldn't expect great results. With an fs of 105 hz, it's going to need some help in the bass department. Your best option would probably be open baffle with a helper woofer.

thanks bob ill try to build v pipe. and listen it if its poor bass. ill try to consider about the sub again. it's a pa driver ,i wouldn't expect a good result with it too much. but only hope that may make me enjoy the music, sometime diy can make me happy more than anything else.

Box wise from published specs, it ideally wants to 'feel' either a ~44 Hz BLH or OB and wide BW 'helper' woofer with a ~250 Hz XO, so a compromise would be a ~22 Hz BIB pipe horn and hope the room loads it down enough to protect the driver when driven down into the low 40s.

OB should be interesting with such a high Qts...

[GM]

In what way? With a 250 Hz XO it's rolled off below its mass corner rendering its medium high Q moot.

Maybe a lower XO can be used with that sort of high Qts...
