Project Category:
Home Theater

Project Level:

Project Time:
1-8 Hours

Project Cost:
Under $100

Project Description:
JLB 135 Resurrection

Design Goals:
Putting a powered subwoofer back into action

Driver Selection:
Peerless by Tymphany

Enclosure Design:
JLB 135 Home theater speakers

Enclosure Assembly:
Needed to make an adapter board to fit new plate amp to enclosure.

Crossover Design:
Dayton Plate amplifier

Tips & Tricks:
Satellite speaker nearly an exact match, had to elongate holes to fit (drill press & file). Original speaker was shielded, hope that doesn’t become an issue.

Not a big fan of powered subwoofers, so kept this simple. Original amp went out & couldn’t see scrapping the unit, too much stuff going to landfill as it is.

About the Designer:
Weekend Redneck, the point of life is doing it yourself.

Dayton Audio SA70 70W Subwoofer Plate Amplifier
Peerless by Tymphany TC7FD00-04 2-1/2″ Full Range Paper Cone Woofer 4 Ohm

    Nice job and I totally agree on too much going to landfill! Shielding should not be an issue unless you are still using one of the old dinosaur CRT TV sets. Flat screen TVs are unaffected by stray magnetic fields.
