I currently don't have a center channel speaker, and for the most part I don't really need one for most content. I do have the urge to build something easy, so, I'm going to modify an old speaker box, and make a small 2-way. The drivers have been collecting dust for many years. The tweeter will most likely be a Morel mdt39. The woofer will be a Peerless 4" HDS. My woodworking skills are minimal, but I hope to make the box look a little better than it looks now. I'll add a before picture when I get a chance. This new speaker may later become a 3-way by adding a woofer in a separate box.

I have the urge to slope the baffle, and carve some large round-overs. That was not initially my intention, but holding the 4" woofer up to the baffle, it just looks lost. I didn't have significant diffraction problems with the 6.5" woofer, but I'm thinking the 4" might be affected by the baffle more. If I cross low, that might not be an issue. I might make a simple baffle, and measure the woofer before I do anything fancy. These 4" woofers are pretty smooth, or will be, if diffraction doesn't change it. https://www.parts-express.com/pedocs...spec-sheet.pdf

To djg.....This box has been around. It was altered to play with this one. This one was a new build about a year or so ago..

I like the look of small speakers, but I want the performance of larger ones. These were fine with a sub, and "OK" without, but a little thin in the bass. The box is too small to go deep. My plan is to build larger 2-ways for my living room that can handle the bass without a sub. I've built some already, but they look really bulky because they are 1 cu-ft and sit on 24" stands. .

I used the diffraction simulator to see if I could find a good location for the woofer and tweeter. The seats in my room are at about 20 degrees off axis, so that's what is shown in the sim. I will probably have large beveled edges, but I ran a sim with and without. Vertical response looked pretty good up to 25 degrees or so.
