new build - Buschhorn Mark II

[spgjmf]

hi folks,
wanted to share my lastest speaker build. Buschhorn Mark II with
fostex fe103e drivers. about 2 years ago I started down the full range driver path and was hooked. I built some small boxes for the little fe103 and used them with my 6em7 se amp. mostly for jazz and classical, some eletronic and
ambient music. loved the combo, but got the need for more ( go figure).

after searching for a plan for the fe103, I came upon the planet10 plans. it was a coin flip between ZigmaHorne or the buschhorn. The horns won, better looking and more fun to build.
The buid was great and the sound is amazing, fuller, more balnced, yet still has the detail i love.
anyway, here are some pictures. I used pine for the inside and birch ply for the outside. I sort'a faked the measurements inside because the pine was 3/4 stock. oops...they still sound really nice. still needs to build the other one :-).

the 6em7 drives the speaker well, better than the yamaha SS amp in the workshop. I have to finish the speakers next. some polyurethane most likely.
I built the 6em7 amp about 2 years as well, with help from the tube forum.
oh, the source is flac or acc files from pc thru diy dac and zen preamp.

best wish to all and thanks to all the folks on the forum who post, I learn a lot here.

Nice job, Jeff!
They are indeed a fun-build, I'll bet they sound great with your amp, too!

Nice build - well done!

I made these a few years ago out of heavy cardboard.
You may want to experiment with filling the triangular voids.

Cheers,

Alex

thanks guys,
I intend to fill the voids with sand on the bottom and pink fiberglass on the upper. do I just pour the sand in or maybe put it in a bag? hmm. sand and glue, not pretty....

If you use sand, make it "sterile" sand (availablility and price unknown to me), as stuff from the backyard may mold and ruin the enclosures. In my BH MkII (and all other cabs with voids), I use kitty litter...cheap, simple, dense and heavy. Pour some in, hit the side of the cab with a rubber mallet for a while, and fill 'er up. I can't remember where I saw it first, but it makes a lot of sense...

Nice build, nice design
What are the placement requirements for them? Do they work near the wall or should be far from it?
