Project Description:
4 inch 2 way bookshelf speaker

Design Goals:
My first ported speaker project. Tuned to the drivers used.

Driver Selection:
Dayton tcp115-4
Peerless dx20bf00-04

Enclosure Design:
Solid red oak 3/4″. .086f3
I wanted them a bit bigger, but the wood was too expensive to redo.

Enclosure Assembly:
Rabbits of 3/8 on tops and sides. The rest butted with glue( no nails or screws) 1/2″ sonic barrier on all sides. 1″ x 4″ flared port in the rear.

Crossover Design:
Lw rl 3200 simple crossover.

Tips & Tricks:
If you want the best finish on speakers of any material use lacquer and many coats.

Conclusion:
The boxes were tuned to 70Hz with the calculator I used. I do believe the hit that mark and then some. Very nice!!
The tweeter however even though it’s matched really well is lacking some. I may upgrade them and the crossovers in the future and update you afterwards.

About the Designer:
