Project Cost:

$500-$1,000

Project Description:

Speakers are too large to be a bookshelf. They are stand mount speakers and are one of the more complex designs I have attempetd

Design Goals:

To create a high end great sounding speaker with adequate bass and decent mid and high end.

Driver Selection:

10″ Woofer Faital Pro 10FE330 294-1340
4″ Mid B&C 4NDF34-8 294-5938
1 1/8″ Morel ET 448 soft dome tweeter 277-074

Enclosure Design:

Enclosure design: Old school design of a very popular speaker Retro design.

Crossover Design:

Crossover is a 2nd order three way design with cross over points at 375Hz and 3 kHz.

Tips & Tricks:

I likely should not have mounted the L pads on the back due to connectors needed for a removable back. The front is reinforced with an additional 1/2 inch Baltic birch plywood behind the woofer. and reinforced. I built speaker stands from scrap 2X2 s I had and elevate the speakers at a 5 degrees so tweeter is near ear level when seated.

Conclusion:

With a rated range both higher and lower than the speaker this is based on and a greater Spl of 92 vs 90. This rather complex design weighed in at 48bs each. The bass is deep, rich and tight. The mids and highs are clear and exact.
