Two 'Project Array 1200' projects

[jbljfan]

Please keep thread clear until the project is complete. It will be awhile before it all to comes together.

Cabinet construction by Funky Waves Audio.
Cabinet designs by Dave Rosgaard. Additional internal bracing by Nathan Funk.
Ideas plagiarized from several forum members and of course Mr. Timbers and the JBL team.
Thank you all.

Boxes curing before veneering.

Zebrawood veneer with trim.

Box volumes were calculated at a design tuning frequency of 32 Hz and before additional bracing. Large boxes are being built to a design tuning frequency of 28 Hz. Actual TBD.

Detail cutting drawings were made for all panels and bracing shown.

...very nice sounding bass, tight, deep, accurate, clean...

The tuning actually ended up a little lower than expected, the 15 is ~26hz and the 12 ~31hz.

I have removed the spurious entries on request of the OP. We will encourage posting after he builds the thread. Coolio...? (er, don't reply to that! :p )

The scales are different but here's the impedance and SPL comparisons:

Note the rising response and higher impedance of the 1200FE-12. You'll have to tweak the network a bit to deal with all that.
