1x18 tapped horn

Hi Sir Jamwa and others

Yes, I'm going to release the plans when I have them in digital format.

At the moment plans are only in 1:10 handy-cad format. This led to some problems when assembling the prototype as I had to cut all odd angels by good guesstimation, or at least trim the angles few times before each piece fitted in even moderately.

The ply was bit warped, that's one reason I didn't use MDF at first. When the inspiration to mock up a proto hitted me, I thought that warped sheets make good protoing material.(and made the bigger panels fitting ill without some exceptional use of elbow grease)

Small benefit using ply at once; panel resonances are different on different density materials and bend modulus(is it correct expression?) is different between MDF and ply.

I must warn you that some of the inner parts (throat area) are made with 27mm birch ply to withstand high pressures more easily. Rest of the cab is about 3 sheets of 18mm BB/WG grade birch.

The cabinets' intention is to do its thang (go somewhere low 30's) in small stacks, 1 or 2 per side. For a larger system, normal FLH would be more efficient.

P.S.

I'm on my way to see Rally-Finland in Jyväskylä area and need to drive some 300km to a friends cabin...tadaa.

Some progression. For next 3subs,

I ordered 10sheets of 18mm ply recently and waiting for the delivery.

Also got drawings in autocad / CAM compatible format, many thanks to Lasse Lukkari.

1200x636x1200 HWD, so biggest shell that could be cutted economically and with relative ease.

Answer to your question is yes. Lab sub 1143x571,5x1143 HWD

Hello mr fly

Wavesub12 was one up project I made for live music bar (Liberte) in Helsinki. I did use 2x beyma 12P1000nd's in a simple fold tapped horns. Sub enclosures double as a stage extension. And are made of 27mm ply.

When tested, I fed 'em with EV CP 3000S in bridge, flat out. Didn't bottom out the drivers, only turned down because of the voice coil smell....Of course with appropriate processing.

Yup

Three cabinets ready now, waiting fourth.

Mandatory rigshots from smallish festivity on my friends backyard from later times.
