Hello, and thanks for putting this together! This'll be my first DIY speakers (and first open baffles) and I'm quite excited, but I've got a question. Do you have any idea if front-mounting the woofer will affect the sound? Along with being easier to do, personally I think it'll look better as well.

Thanks in advance!

Aaron

Hi, A fun and inexpensive project. The original design (not my implementation of it) mounted the woofer from the rear with a beveled (45 degree angle) opening. It was supposed to allow for the time alignment of the tweeter and woofer cones at the crossover point. Since I used a different woofer (with a different depth on the cone) it is probably hit or miss if this is valid with my build. The fact that the original used only a single capacitor for a crossover to the tweeter and I used a symmetrical 6db up and 6db down one probably negates it as well. In actual use it may be moot as room reflections are quite significant in OB speakers. So, sure go ahead and mount it from the front. On thing you can fiddle with a bit is the angle of the rear facing tweeters. I found that by changing the angle and direction they pointed made a lot of difference in how the sound was dispersed. The way I liked it best was at between 30 and 60 degrees and on a vertical axis with the main baffle. Aiming them inward toward the center of the room and outward by just swapping the left and right baffles or turning the tweeters themselves outward changed the sound. Room placement is also VIP. One thing however....they do not work well in corners or really close to the wall behind them. It seemed that the best locations were about where my electrostatics sound best (duh..they are bi-directional too). In my room about 4 feet from the front wall with their center line about 3-4 feet from a side wall and angled inward about 20-30 degrees.

Good listening
Bruce

Thanks for the response and all the great info. I'll post here with how it goes once I get a bit further along.
