Modula M/T's under construction

**chasw98** · **09-16-06, 09:47 PM**

I have built and posted some pictures of the other loudspeakers I have built. There is a method to my madness. They will all use the Seas H1212 tweeter. They will all have Oak veneer stained with sedona red minwax stain, and they will al have the front vertical edges rounded. Here is the beginning of my 4 Modula M/T surround loudspeakers.

Here is some further progress I made today.

**chasw98** · **09-16-06, 09:50 PM**

And here is as far as I have gotten tonight. I actually got one speaker far enough along to test it with music and it sounds pretty **** good for a little old 2 way!

Lookin' good Chas. If you don't mind my asking, what kind of acoustic stuffing is that?

Eventually my goal is to build just a pair of Modula MT's (Rs28a version to match the Nat P's) and possibly Chris's MTM center, partial BSC for top of TV placement.

It is 2" wedge foam from http://www.foamandupholstery.com/wed...__sheets.htm#4. It's only $8.96 for a 24 X 48 sheet and has a pretty good NRC rating. Here is a shot of the M/T with the veneer on waiting to be stained and made pretty. Now I only have to make 3 more of these!

Wow, that looks awesome. Seriously mad skillz on the enclosure!

Also, I'm sorry if I missed it, but what design did you use? Or was this your own design?

**chasw98** · **09-18-06, 01:39 PM**

A very smart and talented man named Jon Marsh came up with the design. You can read about it here http://www.htguide.com/forum/showthread.php4?t=13154.

The end result looks almost identical to Red Oak.

Wow Chuck... you guys continue to amaze me how you put together these speakers and make them look so good.

**chasw98** · **09-22-06, 09:23 AM**

Thanks Sonnie, but I know where every mistake is. My wife says it is beautiful and I tell her about the scratch on the bottom of the speaker that is a half inch long! Now, if I did it over, I would do it this wayyyyy............

**chasw98** · **10-03-06, 06:41 PM**

Here they are, 90% finished and in place.

**F1 fan** · **10-03-06, 11:08 PM**

Impressive!Chuck those look great.In conjunction with your mains and centre channel that is one heck of a surround system you have put together.

BTW were did you score those ceiling mount brackets.

**chasw98** · **10-04-06, 04:15 AM**

Thanks, Fred. Those are Omni Mounts Pro Studio Mounts http://www.racksandstands.com/OmniMo...es-OM0015.html . They are little more expensive than the ordinary mounts but they are rated for 30 pounds and will hold a speaker in any position you get in and not move.

**Sonnie** · **10-04-06, 04:41 AM**

Yep... those are super nice... very well done!

Great work as usual Chuck. I really like how you take care of the small details with such care.

Thank you. I appreciate it. I have just stained and painted the speakers for now, but I just acquired a HVLP sprayer. I am going to use that to apply the polyurethane or crystalac or whatever I come up with to apply the final finish to them shortly.

Chuck,
Did you build your Modula's with a 1" or a 3/4" front baffle?

3/4" front baffle.

Hey Chas what do you use to cut out for the tweeters side posts?

VERY CAREFULLY! Freehand with a router. I will draw some guidelines after I have routed out the mounting surface and the hole for the tweeter to fit through. Then I just draw a center line across the tweeter cutout, from the centerline I allow 3/8" on either side of the line and mark it. Then I just freehand. The side post cutouts will never be seen so if it is not the prettiest, it won't show.

**dynamowhum** · **11-05-06, 01:04 PM**

Chas I would not try and free hand with my router. It is a PC 7529 and I would be to clumsy with it. Last time before I routed anything I tried drilling 1/2" holes where I thought the through holes center line would be. I worked but not as nicely as I would have liked. I had to cope a little to get it right. Cheers.

I tried pre drilling the holes also and just never got good results. Practice on scrap wood with freehanding. I always go very, very slow so the router does not take over and slip away. I also only route off small bits at a time so it takes a little while.

**dynamowhum** · **11-05-06, 03:06 PM**

Did you use the 1/4" upspiral bit for this? I might try this with a roto zip though.

**chasw98** · **11-05-06, 05:02 PM**

Yes, a 1/4" up spiral. Roto zip would probably work well. Just keep it straight up and down.

**southworth** · **11-05-06, 07:55 PM**

Chuck,
Did you use a 3/4" roundover bit on your front baffle?
