Are you going to take over the living room with these monsters or have you moved upstairs yet?

Probably staying downstairs in the family room as it was when you were here.

I built them for moving the stereo into the small downstairs music room, but I think they will sound better in the big room and maybe they can go into the corners which be more WAF.


Looking good professor. Getting close.

Thanks Charlie

Gettin rollin on these now.

1, 2. Gluing on the other back panel
3, 4. Install wiring
5. Test fitting the front baffle
6, 7. Gluing on the front baffle
8. Ready for the final 2 side panels

The side panels have a 45 chamfer cut on a table saw. They are 53 inches long and for some reason the chamfered edge is not straight. So when it fits up under the front baffle overhang it leaves a gap. All 8 side pieces are the same way. Tomorrow I will try to recut them, as there is enough extra meat to recut that edge, but I'm not sure why it happened. Will have to make extra careful saw setup.

Looking mighty good Rich. Looks like you are getting pretty close to wiring and testing.

Keep up the good work.

Slow now, but 2 of 4 boxes are built and wired.

I hate to sound naggy, but any more progress Rich? Just curious.

Thanks for the bump Steve!

The arrays are on ice for now. I have bigger fish to fry at the moment.

But I need to clean up my audio messes all over the house, so I will have to finish them soon.

Tapping on the undamped box makes the large internal panels ring with high Q. So I need to damp and brace those.

I was wondering if you have had any further time with your line array speakers Rich?

Cheers

Hi Steve,
Not much done lately, except moving them around to keep them out of the way. :D  I got a set of Legacy Focus SE last fall, they have proved adequate for listening, so I haven't made any progress on the line arrays. But I have lately been thinking about working on them again.

I need to damp the hardboard to move forward, and 2/4 cabinets are fully built so I'll have to squeeze the damping sheets through the small driver holes. I would use self adhesive roofing membrane from GAF but it's not readily available in single rolls, and a pallet is 20 rolls and I don't really need that much. So I'll have to find something similar. There is patch material in 1 foot wide rolls, but it's thin so i might need couple layers, or both sides of the internal panels. Some progress is made however in that I now have a stereo amp with plenty of power for the line arrays. Thanks for the nudge, Steve. It's always appreciated!

I can understand summer time is out and about, cookouts here etc. Pretty much finished with my two ways, but only an adjustable control tweak, not finishing the outsides as I would have to move them and it took so long to get them right. So the outside still looks like plywood.

However, soon will be fall and winter so got to make the most of summer time.

cheers and continued success Rich.

I usually work on speakers during the summer and hibernate from it in the winter. So now would be a good time to work on them. I have the time, but not into it now especially with good, full range commercial speakers in the house. I can accept their flaws without taking it personally, or punishing myself with perfectionism, so it is altogether a more pleasant experience. No rush to get back into that frame of mind. But I will someday.
