I have been chatting with a local audio DIY enthusiast about a pair of speakers he built. They are full range towers with Usher and FounTek drivers, and my goal is to go listen to them by this weekend. I just wanted to get feedback from one of our seasoned speaker builders to see if these are worth my time. Based on our emails back and forth, they do seem well designed with quality parts, and I'll have to let my ears make the decision as always. He says they sound better than most speakers up to $10K, but I realize that everyone is biased.
I built this pair of speakers a year ago using 4x 7" 8945P Usher woofers, 2x 9950 Usher dome tweeters, and 2x FounTek ribbon tweeters. The crossover components are high end caps and coils, along with the binding posts and plates. The speaker cabinet are 1.5" MDF with solid hardwood.
I wanted to have the high frequency response up to 45k hz of ribbon which is very nice and airy; 3D like. The ribbon is crossed from 7k hz up but is very limited in the vertical dispersion. This is where the dome tweeter covers, also allowing me to cross much lower to the 7" mid bass at 1600 hz to avoid beaming effect. The bottom woofer is crossed from 400 hz down with a rear ported design tuning at around 50hz at f3. The 7" Usher 8945P is my preference even over the popular Scanspeaks, as it has very low harmonic distortion.
