Project Description:
I produced this center channel from what I learned on this forum. Thank you. I wanted something to put on the fireplace mantel under the TV. So space was limited. I did want the challenge to build something from scratch. So this is it. An MTM nested design with 2 Dayton TCP 115-8 woofers and a Dayton NDFA20-6 tweeter. It worked well and I am happy. I changed the schematic from the original 3.7 ohm resistor on the tweeter to a 1.5 ohm as I felt it needed to be a bit brighter. It’s the only other resistor I had laying around. That worked well.

Design Goals:
A better center channel than what I had before.

Driver Selection:
2 Dayton TCP 115-8 woofers and a Dayton NDFA20-6 tweeter.

Enclosure Design:
Box has external measurements of 20″ wide x 6″ tall x 7″ deep. It is ported with two 0.75 inch ID x 2.5 inch long ports.

Tips & Tricks:
Don’t seal the box with glue until you are sure you are done.

Conclusion:
I love it. Worked out well.
