I had this professionally built by a Cabinet maker who now makes custom sub enclosures, For a Peerless 15 inch 3000W RMS subwoofer
This is a slot ported enclosure, very heavy and sturdy, made out of Birch and Oak I believe.
Tuning is around 35 Hz, I never got the official number but it was geared more for output at the lower frequencies for Home Theater.
About 3.2 Cu Ft on the air space if I remember correctly
This is a passive enclosure, so you will need a External Amp to run with your sub.
It has that tough bed liner material covering the enclosure so you can just add some more of that to the enclosure if you get scratches or nicks. This also adds additional rigidity to the enclosure. It also has bracing for further rigidity.
The Peerless 15 I had in this absolutely pounded my house, I was only running 2300 Watts bridged to it and it was almost too much for the house.
This thing is of substantial size, please bring help to load it or a dolley. I have a fused back so cannot help much to load it.
I obviously cannot ship this due to the size and weight. I had this shipped to me via a freight truck so it is about the size of a large End table.
22-In wide
24-In tall
26-In deep
I also made a custom Sub Decoupler Pad, that I will include with the sale.
Pick Up in Plano, I cannot deliver this, it is currently in my climate controlled storage unit.
