Midnight Monoliths

Designer: Strandt

Project Time: 1-8 hours
Project Complexity: Hobbyist
Project Cost: $100-$500

Driver Selection
Mid and Bass drivers are 4″ with a range of 70hz to 6khz. I used a Pezio tweeter with a 47ohm resistor, with a range of 3khz to 25k hz to finish it off.

Enclosure Design
The enclosure is made out of MDF. IT is a very, tightly made box to minimized reverb, with no internal dampening material.

Amplifier/Crossover Configuration
the tweeter I crossed over at 3.5khz. The bottom woofer is using a low pass crossover at 500hz, and the mid has no crossover.

Enclosure Assembly
I used a nail gun to assemble this enclosure, with a very thick primer over it, then 4 layers of an oil based high gloss black paint

These speakers are surprisingly clear. Great High’s, Outstandingly accurate lows. I was planning on using them with a Subwoofer, but it is really not necessary.

About The Designer
Dan Strandt has been selling home audio and designing home theater systems for over 5 years. Unhappy with the quality and/or price of speakers avalible in retail stores, he began building his own. Eventually Dan wants to make a career of custom speaker design.
