Default Under Construction FrugalHorn LegHorn

These have been modified just a tad, something I've been kicking around for a bit.

The top 9 1/4 inches have been trimmed parallel on the front/back, with a little ledge left at the bottom of the back cut. Then trimmed the flare at the bottom off a little and made some bases 2 1/4 inches tall.

The reason- I routered a couple of holes just the size of the top of the horn, toed in a few degrees, into a 30" x 60" x 1 3/4" butcher block maple cabinet top. I am going to slip the horns up into those holes until it stops at the ledge on the back. This will leave 7 1/2 inches of the speaker sticking up through the table top, but puts the top at 27 3/4 inches, so that's where the bases come into play.

With the entire curved flare on the bottom, the desk would have to set out away from the wall too far, or the speakers would have to be moved too far forward on the desktop. These will be the rear legs, I have adjustable Ikea legs for the fronts.

Computer desk here one of these days, I just thought I'd better get some pre-assembled shots for context, these have a few coats of super blonde shellac, the fronts and tops veneered with 1/64" birch ply - wouldn't use again, very thin plys.

I could upload the pics of the speakers, but get a size violation with the desk pics, ànd they are smaller. I'll use a camera next time ànd resize them.

And don't hesitate to delete this thread if it's in the wrong section or is otherwise offensive.

The back curve does contribute to the full expression of the bass. But there is a firm in Ireland that is trying to commercially market a version of the FH3 with the entire back bit cut right off. They, and the review i saw, feel that works OK, so despite the mutation of the rear curve you have made, you should still have a good speaker.

Yeah, I knew it was going to be a compromise, but then again having the driver right over a large desktop isn't optimal, either. The base is 12 1/2" long now, that cut was also parallel to the front (I'm lazy).

And there's the wall that's going to be pretty near the back, hopefully the toe angle will open up a little breathing room.

Even with these issues, I bet they will be pretty decent computer speakers, Alpair 7.3 loaded.

I bought these flat packs from you a while back, and have to say they were a joy to assemble, I have way more work in the simple veneer and shellac job than assembling the cabinets ever was. Depending on stability, I may have to tack a couple of cleats onto the sides for the desktop to rest on, but I can do that when assembled.

Yes.

Ignoring glue drying time Chris can do the raw assembly of a flat-pak quicker than i can pack one up for shipping.

Still a little cable management to tidy up, but it's jamming now.

The sound quality is pretty impressive, I'm pleased.

They have the full amount of stuffing in the front chamber, I think they are near perfectly balanced. The drivers don't have much time on them, but "Flight of the Cosmic Hippo" reveals that they really can produce surprising bass at even low volume.

The imaging is spot on, I have to wonder if the desktop surrounding the columns isn't helping, in a near-field sort of way. And the toe-in seems to be spot on (good thing, huh), it's like the computer screen is the source.

This is exactly the effect I was going for, killer computer desk sound.

It took a while to figure out exactly what the notch in back of side panels was for - pretty darned cute, mate

try Patricia Barber, Modern Cool, "Post Modern Blues", or Bozzio, Levin and Stevens -"Duende" for bass extension, slide and articulation, and on the Bozzio track, the textures and imaging of what must be a very large drum kit

just Google "Terry Bozzio drum kit" - I sure don't envy the roadies
