Starting with the woofer, I was immediately intrigued by the new Morel Hybrid series of drivers. They offer a good combination of specs and performance, and sell at what I would consider the upper end of the mid-priced drivers. From doing some quick modeling of the parameters, I liked the looks on paper of the H6.1 6" driver. It has specs to make it work well in a mid-size vented enclosure, and has a very good sensitivity compared to other drivers of its size. Cosmetically it is very attractive and uses a coated DPC cone, large rubber surround, and nice lowstray- field neo/ceramic motor. I did some quick measurements of the frequency response, which offered a clean response up to 2 kHz, and the parameters matched Morel's specs fairly well. The H 6.1 looked like a good choice.

Since we were using a relatively high-end woofer, I knew that I wanted to start looking at Morel's higher-end tweeter offerings. I have used the MDT-30 before and know that it is a very nice tweeter, so I wanted to use something similar but perhaps a little better suited for this design. I did not need ultra-high sensitivity or ultra-high power handling, and since the H6.1 is essentially shielded, a neodymium tweeter would be good choice. The MDT-39 seemed the perfect balance of cost versus performance; with everything I needed including the shielding without too many superfluous features.
