Default ideas for widebander?

Any ideas of a suitable widebander for use on OB. So far the ones I have noted are the fostex 208 sigma, 10" or 12" audio nirvana cast frame, eminence beta 12lta. I was thinking a target of 95 db, and reasonable cost (under $500 a pair).

Visaton B200 and Wild Burro Audio Labs' Betsy are well within your budget. I'm assuming this is only one driver per baffle (no helper woofer)? If so, you'll want a driver with a high Qts (and the baffle will still have to be quite big). I'm listening to the B200 right now in 48"hx38"w.

The Fostex 208-Sigma is a great driver but the Qts is very low and you'd absolutely need a woofer. However, building with a woofer is actually a good idea and gives you a huge range of drivers to choose from (as long as the woofer is lots more efficient than the fullranger), according to: OB Theory

Hi, the Ciare CH-250 (version MM+) is a very good driver for OB.

I've been itching to try something with a 10" pro audio driver like the Precision Devices neodymium 10" mid with a nice ribbon tweet and a couple high-Q 15s all in OB. The 10" is not exactly 'wideband, but would do 200-2k fine.

No O.B. but I am just finishing a pair of BLH for the Beta 12LTA. I like that driver more every day.

I'm interested in your impressions of that Eminence driver, good and bad. I like large paper fullrange drivers.

I didnt like the Beta 12 at first until I ran it for a few days and loosened the suspension. It needs a tweeter of 98-100 db crossed at around 8000hz and some polyfill stuffed between the whizzer and the main cone. It works very well in the recommended 4' vented box. This setup makes my 45 amp sound loud!
