I built two of these. They feature a rigid compact design with force cancelling.

Each subwoofer contains two Dayton Audio UM18-22 drivers.

25mm baltic birch baffles
18mm baltic birch otherwise

Pocket holes could be filled and sanded
I didn't drill routing holes for the wires but that can be done

Approx 26"w x 20.25"d x 20.25"h

Cabinets - Free for pickup in the Seattle, WA, USA area
Drivers - $150 each (plus shipping if you aren't picking up)

No xover included. MiniDSP 2x4HD works great.

If somebody wants just the drivers or just the cabinets, that is fine too.

Correct, the woofers are wired out of phase from each other. I have two of these cabinets built which would be 4 x 18" woofers total.

I will sweeten the deal for anybody wanting the full set of subs - I'll include a Crown K1 Amp to power them (available for pickup). This outputs 750W at 2ohm so plenty of power.

What did you replace these with - it looks like an EXCELLENT implementation of a W-frame dipole subwoofer!

Thanks! Yes they were really nice. Sturdy, compact, and force cancelling. I still have a v-frame dipole sub and am working on some sealed subs.
