Re: RMAF: Most enthusiastic demo

Yes... that is the new 4" XBL^2 driver that CSS is producing. We had both a MT two-way which could be wired without the tweeter and a line array using several of the WR125's, ribbons and a couple powered 8" drivers. The MT worked very well in the smaller room with the extra room gain. In fact... they were very usable without a sub in the smaller room.

The response on the 4" is very flat out to about 14Khz. We had it wired both with & without the tweeter and I prefered it with the tweeter. A simple tweeter crossed high with a single cap and leaving the 4" to roll off acoustically should work wonderfully. Once I get a couple drivers I'll mount them on the baffle and do some measurement and simulations. The tweeter will probably need to be padded also, depending on the tweeter, but overall it makes a great small two-way. It really is a great demonstration of XBL^2 that the 4" driver is usable at all down to 50HZ. I have plans to use it on a couple projects including a small computer monitor speaker.
