Yes, that is a "bass trap" and there is one above the entertainment center and one behind each valance where the curtains are. I have a movable column trap that matches the wall that I place bellow the triangle when the WAF is not around.

The added insulation would pay for it's self and the IB subwoofers in a few years.

It is actually closer to 7.5" since those are 2" x 8" joists. I am currently looking into improving the thermal properties up there. I am looking into radiant barriers or addition insulation. I would like to convert a large section of the space into an addition room. Be it a theater room or additional bedroom. I am just worried that with the Florida heat, it will be too much.

Does anyone know of speaker building shops in the New York City area where I can take my drawings? I am not good at cabinet building whatsoever!!! There used to be a shot on Jerricho Turnpike, but have closed recently.

Any help would be greatly appreciated.

You should a new thread in this area and you'll probably get some help there.

Thanks OP

great info in this thread!~
post #785 of 1121
I just wanna say.....this thread made me join this forum! Just sooo many amazing builds here. I do some woodworking here and there, mainly building solid body guitars occasionally, storage cabinets, scroll saw work etc etc. This thread has inspired me to start building some speakers though.

I have a third floor like that and it is completely insulated and done in low e insulation. It works like a charm. shout back if you have any questions.

I've had these PE parts since 2006 but tooo many things get in the way of what we love, ya know? It got kind of late and I made the decision to hack this thing together and spray what I could before it was too cold. Just get the CC singing and bother with the finish-the-finishing next spring. So here is ET, that is what the family is calling it:



the top of the pylon has threaded inserts and the speaker is through bolted to it and actually sits on two little strips of isolation rubber on the pylon. Then the cable goes down through the pylon and there is a termination cut into the back of the unit with forstner bits and a chisel:







The dumb thing is, I thought I screwed up because there was no sound at first. Of course, you have to change to multi-channel from stereo!
Sounds good--tweaking and cable changes to follow...

Very nice! Any particular reason you didn't seem to to recess the tweeter and driver in a couple of the designs? I take it the non-recessed ones were your earlier projects?

Can't argue with you on the look part, as that's personal preference... But perform better? Why? Many high end speakers have separate cabinets, JMLabs Utopia, Wilsons, latest Salk HT3, etc. There's actually some advantages to having separate boxes for the drivers.

Late reply...
No particular reason.... I just didn't have router/trimmer. So far no issue with the sound.

They are not commerical. As for which design, I'm taking a guess based on the looks and drivers. I believe they are the RS TMWW found here.

Beautiful! They look like they have a bit of Sonas in them.

You are correct, sir! The Dayton RS 3-ways
and thanks, dbldare--high praise. Certainly more than I deserve. How did you guess on the Sonus? That is where the idea came for the center.

These are diy-if you looked at them in real life it would be easier to tell heh-heh.

The first time I saw a set Sonas Fabers was, oh I guess, about 12 years ago and they were like no other speaker I'd seen up to that point. I'll never forget how they looked, much less sounded.

Again, beautiful work. I just finished a THT build that looks like complete crap! I envy you guys that can build a DIY project and make the pros stuff look like junk.

My speakers are still unfinished, the wife won't let me bring them upstairs yet because she doesn't like the look of MDF. I still haven't finished them after about 6 months of using them, I'm enjoying them way to much.

Wards, that veneer is godlike....but it pains me to see all that nice equipment, and no sound treatment or a dedicated listening room...

Here`s a pic of my diy-stuff. The 4-way speakers are really a long-time project, ended up as asymetric no absorbers, 1.order "oversized" filter,(low R) heavy duty solid core(low R), undertuned aerodynamic bassreflex

These guys are really "dynamic speakers" how they should be done. Even my horn-friends struggles with their jaws when listening. And seamfree, weightless aso. But they don`t know how many hours I`ve struggled to get to this point.

The "rack" has been an old TV-cabinet..

Very very nice! I'm diggin' the dome midrange.

Very nice R.Solhaug!

Welcome to the AVS.
post #806 of 1121
Awesome job on your speakers. I have always wanted to build a line source so I have to ask, How do these sound?
post #807 of 1121
I noticed a post that you have built some North Creek speakers including a center. I am interested in what they sound like. Any opinions? Are they worth the effort in you opinion? Any comparisons to anything you have heard in the past ?
post #808 of 1121
I can comment on the North Creek Borealis - All Scan Speak driver version.

Very nice smooth sounding speaker. Gentle roll off on the bass, very good imaging.

Are they worth the cost over buying just the raw drivers? If you not exeperienced with crossover design, or box design then yes, do it.

Just thought I would share my recently completed entertainment center. I am guessing I spent some 300 hours or more constructing it. Constructed with solid and plywood red oak (screws, glue, and dowels were used). I created a Sketchup model to confirm proportions before I started constructing it. The top three panels flip-up and recess into the unit, the bottom two panels are held in place using hidden neodymium magnets.

It measures:
8 feet wide
28 inches deep
36.5 inches tall

Finish:
Lightly sanded with 150 grit sandpaper
2 coats Constatine's Red Mahogany Grain Filler
1 coat of 1:1 mix of Minwax Sedona Red and Red Mahogany oil based stain
1 coat of General Finishes Red Mahogany oil based stain
10 coats of Minwax Satin Wipe-on Poly

Note that the three top panels were finished a little different from everything else. Transtint Red Mahogany dye was used after sanding and grain filler was applied. The remaining steps are the same as above.

Speakers:
(5) of Zaph's BAMTM
(4) Mach 5 Audio MJ-18
(2) LLT Ascendant Audio Avalanche 18s (sonotubes)

To get a sense of size of the unit, the television is a 50" plasma and the sonotubes are 28" in diameter and 7 feet tall.
