Hey all,

I finally got going on my DIY speakers, starting with my subwoofer.

Box design: Sealed 2 cu. ft. cube
Construction: 1" mdf walls; 18.5" exterior size; mitered edges all around.
Driver: Dayton RSS315HF-4 12" High Fidelity Subwoofer
Amp: Dayton HPSA500 500W subwoofer plate amplifier

Here's a couple pics:

I plan to veneer and finish shortly, once I decide on room colors. I'll either use maple veneer and stain with a dark wine red, or I'll use Ash veneer, and go black. Not sure yet.

Then I'm planning on building a set of GR-Research AV/3s, along with a center channel. Then a pair of surrounds... If I'm lucky, I'll finish it all by Christmas!

Also, I've attached a link to my build thread...check it out!

Looks good. How does she sound?
post #156 of 1121
I've only got about 3or 4 hours listening on it total so far, but I am pretty impressed. It's more powerful than I would've expected, and it shakes the house more than I would've thought. I'm still planning on integrating it into the room using the Behringer FBQ2496 and some good measurements, but I've been pleasantly surprised at how good it sounds already.

Hopefully that means I don't have big room mode issues.

Note that if you read my build thread, I indicate I'd like to build two... with how good this sounds now, I'm carefully rethinking that, but I already have the other driver, so I might do it anyway.

It sounds tight and accurate, with very little boominess. I would also describe it as fast, and it's quite musical. I'm very happy that I went with this design; it's going to meet my needs very well.

Now I've just got to figure out what finish I want on it!

Here's some construction pics from my array (4) of Dayton 12" Titanic sealed subs, driven by 4 channels of Crown XLS-402 power through a BASSIS LT. These are 1.17cf enclosures made from heavy duty 16" sonotube.

Baffles in place ready for routing:

Top and bottom plates are made from those round pine blanks from HD:

Legs installed and bottom plate test fit:

Upper chamber created (for concrete):

Concrete poured:

Wrap applied (naugahyde) and top plate installed:

I wanted to be sure I could use them as tables, and not have to worry about vibrating my Mountain Dew bottle off onto the floor

p.s. I'm glad I looked again at this post. I had erroneously linked the thumbnails. Now you should be able to see a little more detail.

My Finished Nat-Ps

And the build Thread: http://www.htguide.com/forum/showthr...3&page=1&pp=35
post #161 of 1121
I'll echo what I said on HTGuide, those are absolutely beautiful!
post #162 of 1121
Wow, if my Natalie P's came out half as nice as those i'd be a very happy man! Very nice work.

After building a pair of North Creek Music Vision Signatures and the 18 Leviathan subwoofer back in 1998, I finally finished the matching Vision Center. It only took me eight years. I have the Okara II Spirit kit I'll use as the surrounds boxed up in the garage and hopefully they won't take as long to complete.

Beautiful, and nice craftsmanship! Lovely roundover fronts.

post #168 of 1121
Yeah these speakers are really nice! I imagine they'll get even better as I don't have them set up properly yet, but how do these compare to your big TMWW towers?
post #169 of 1121
Derek, those look outstanding...What kind of veneer is that? And, is it bare veneer or is it treated?
post #170 of 1121
Finally got my TBFC/G version Modula MT's up and running. Heavy-flaked raw white oak veneer, teak gel stain, brushed satin Varathane Pro finish. Baffles are flat black marine enamel finished with sprayed oil-based clear Varathane Pro satin.

The sound...I'm very pleased with everything I've thrown at them so far. The only thing they don't like is badly recorded and produced material. I guess that's what I should expect with speakers as revealing as these.

I'm very, very happy with them!!

Thank you so much, Jon Marsh. You're the man!

post #171 of 1121
Although I've had the parts for these for over two years, it's been hard to get them done. So this summer I piggy-backed the Modula MT project on this one and it worked out pretty well. Instead of cutting four baffles, I did nine...and so on. I'm very happy with these as well.

The center speaker is quite amazing in its ability to deliver dialogue as well as musical instruments and movie special-FX audio.
Full report is here:

Nice work!
post #173 of 1121
Very, very nice. Do you have a more detailed description of exactly how you did the black painting and finishing?

Hey thanks, I used some curly maple veneer I got off of Ebay and sprayed 2 coats of lacquer and a few coats of clear enamel on top of that.

My sonosub:

Design Thread:http://www.avsforum.com/avs-vb/showthread.php?t=726584

Design: Vented, 6x27" port, tuned to ~14.5hz.
Enclosure: 24x48 sonotube. 1.5" thick mdf top cap + .75" outer panel, 1.5" mdf + .25" ply bottom cap + .75" outer panel. Driver is recessed in outer panel.
Driver: TC sounds TC2000 SVC
Amp: Buttkicker BKA1000
EQ: None
Fabric covering: Headliner material from JoAnn's fabric. 54" long by 3 yards total.
Total Cost: Approx. $800 for everything, including incidentals.
Prior speaker/sub building experience (0-10): 7, based on doing many car audio enclosures. This was my first home theater build and first sonotube build.

Summary: I am EXTREMELY happy with how the sub turned out, both aesthetically and how it sounds. Coming from the car audio background, im used to deep, loud, and clean bass. This sonosub is as close to that as I can imagine. This thing goes deep and loud and is very tight, not muddy. Building the sonosub design was not hard at all. I would do it again in a heartbeat.
