The HiVi F8 had good reviews, could get down to an F3 of 35 in a relatively compact vented box, and is rated for a crossover at 2,000, with an SPL of 89 below 2,000 Hz. The rest of the specs really worked well also, including off-axis frequency projection. The choice of a Morel tweeter came from listening to some 3-way speakers that my younger brother had made. He used Morel tweeters and they just sounded so clean and precise that I wanted to use them in my project also. I'm very happy with both drivers, especially the large listening sweet-spot compared with many high-end speakers.
I used an online enclosure calculator to finalize the volumes and vent length. The only design problem that I ran into was that the vent needed to be longer than I had planned for the depth of the box. I either had to make the box much deeper or use a vent that opened to the top or bottom of the box. As you can see from the design, I decided to have it open to the bottom, with a pocket built into the speaker box to accommodate the vent.
I used the Dayton XO2W-2K 2-way Crossover (Part #260-140) and I'm happy with this choice. Here'a the parts list that I used for this project. Your Shopping Cart Item Qty. Ordered Qty.

See the pictures for a detailed view. The enclosure material was .75 inch MDF and I used pine pieces to strengthen the joints. This turned out to be a little time consuming as an approach, and I might handle the joints differently if I redesigned this box. To finish the box I primed with white primer, glued printed fabric to the sides, painted the front and back with black latex, then finished with four coats of water-based polyurethane (brushed on). To highlight the yellow color of the F8, I used yellow-plated #6 screws to secure the F8 (available form McFeely's Square Drive). The MDT-29’s are secured with black-anodized truss-head screws.
The result is attractive and the sound is a big improvement over my previous speakers, which were Creative Soundworks M60’s. The speakers are installed in a 1,000 sq. ft. multipurpose room and music is well-balanced and accurate throughout the space. I used these originally as stereo speakers but now have them as the L&R mains in a 7.1 channel system. As stereo speakers they were a little over-driven to fill 1,000 sq. ft. As part of a 7.1 system they are plenty loud enough to fill the room. If you have similar design objectives, you might like to use this design.
