My HDT are almost ready
01/25/06 at 23:10:58
 
I'm actualy finishing the veneer with a friend.

I expect to do the holes friday, sand them and apply the gel urethane and oil to fishish the surface during the week-end.

About the back port, I'm curious to know if there is a reason for the square hole instead of a round one ?

My room is pretty big (25' X 15') and I will probably always use the port since I read that it's recommanded for large room.

What about a round port having the same surface of the square one ?

I will post pictures of them as soon as I can install them in my living room Smiley

I think the back port is the shape it is to facilitate youīre hand fitting through to make tweaks ??? I for one would not have wanted a round hole for putting in the foam for the alternate tuning tweak Smiley

I choosed a round port.

the foam in the button as been installed in the assembling process actualy.

I made all the holes today, started to sand the veneer. Tomorow I will round the edges, continue the sanding to 400 and apply my first layer of eurethane gel.

The cabinets are made of 3/4 baltic birch, the veneer is 2.5mm thick solide african mahogany (acajou) and an insert of 2.5mm thick teck wood in the center.

I plan to use a marble or granit top plate and will forget about the round shape for the front grill as I never use the one on my other speakers.

Here are some pictures of the process, I'll take some other tomorow.

They are recessed by 2.5mm but i can go deeper if it's necessary. I would had like them to be flush mounted so we don't see the baltic birch.

Is there a use to make them deeper ?

So far they are very mat because of the dust but I hope the color will be nice.

I don't want them to be gloss but more satin so I chossed a gel finish applied by hand.

Franksmith,

  Looks nice so far, I love the idea of the strip of teak up the middle. There going to be sharp.

  The big reason for the depth of the rabbet for the passive has  more to do with shipping (deep enough to be recessed) than sonics. It was also an idea that it could self center itself in the hole.

    Shoot some more pics when you have them done.

Yeh Zygi knows his HDTīs Smiley I was mainly thinking that they look nicer with the foam of the surrounds recessed level / or just below the surface of the speaker, just a matter of taste Roll Eyes but like Zygi pointīs out shipping them about will be less traumatic. Nice job

p.s Love youre old sī moded cīs Zygi, giving them a cosmetic over-haul Smiley

The color looks fabulous (reads, same as mine Smiley)I would have used the veneer thats on the back on the front though ,but thatīs just me  :)??? But those corners are a bit sharp for their intended purpose of minimizing baffle edge reflections  ???

The veneer is the same on the back than the front it's just that I bough 3 X 8 foot of the same tree.

2.5mm veneer are very hard to find and since I had 2 parts with similar pateren I used them on the back but the motifs are really nice.

Ah ok I thought you had the same as mine, all came from the same tree also wide enough to cover the whole side. It would have been bugging to have one speaker looking very different from the other. Smiley

p.s have you found the marble/granit fro the top? that sounds like a great idea. Wish I had thought of that before I piano black lackered the tops Grin (thats 15 coats polished with waterpaper to a sheen Sad) Black granite would very nice

Looks like these are being built at an IA shop.

Boy, if I knew then what I know now I would have been building a pair of Imperials in shop and damaging something.  :)

Take care,

Corey

Howdy Franksmith,

Your HDT's are lookin good! I just noticed your equipment and must say you have a great set up to compliment the HDT's. I once had the Joule pre - what a honey - keep up the posts and let us know when you get them singing.
