I finally got around to veneering my Dayton Budget Project. Check it out.

A Living Prayer 3

A living Prayer

2006-12-27T19:45:00.000-08:00

The reason I have been posting these is because There seems to be some harshness in Alison's voice when She starts singing loud in my favorite song. I've been trying to figure out what the problem is. And it could very well be my hearing.

A Living Prayer

2006-12-27T16:37:00.000-08:00

The upper section of this graph is a classical piece the lower section is Ron Block & Alison's "A Living Prayer"

I inserted a line and the word "here" to mark where Alison sounds harsh to me.

To do this measurement I ran a CD player into a line level input on my sound card and then started the Spectrum Lab software..

Now, do I understand this correctly, that the amplitude graph shows peaking in both pieces of music but more so in Alison's song? And certainly where I notice a harsh sound? Couldn't this cause harshness?

I've got my nifty LED light in the background. Actualy it looks even cooler than it does in the picture. It has a remote control that will change colors, program color changes, dim and other stuff I haven't figured out yet. You can get one at http://www.ledpower.com/

Stands

2005-06-26T16:59:00.000-07:00

I veneer the center section of the stands then add the tops and bottoms. I do this to get a decent edge between the two. I use the Duplicolor spray-on truckbed liner for the tops and bottoms giving them a matte black textured finish. The veneer will get a medium stain and polyureathane that will match the speakers.

RS Modula MT, how they sound

2005-06-21T06:57:00.000-07:00

In my opinion they sound just like the picture :) AWESOME.

I've been listening to them this weekend, and then some. Jazz, Rock, Classical. It's like there is no speaker at all, only music.

Big thanks to Jon Marsh, Darren, PE and everyone who answers my lame questions.

Now it's time for the veneer.

2005-06-11T17:47:00.000-07:00

Ok, so I'm getting excited and taking too many pictures....

2005-06-11T13:05:00.000-07:00

Here's the front of the baffle, both drivers are recessed. Having an extra piece of MDF to practice on was important.

2005-06-11T13:02:00.000-07:00

Heres the back of the baffle, I slihgtly rounded over behind the woofer.

2005-06-06T18:11:00.000-07:00

I thought some mighty be interested in how these are packaged. I thought they did a pretty good job the rim of the speaker did break through the side of the box just a little, durring shipping but everything seems ok...

2005-06-05T20:03:00.000-07:00

I didn't have any time to work on them today but I had to stack some pieces together to get an idea of what they are going to look like.

RS Modula MT Box and stand progress

2005-06-04T15:43:00.000-07:00

Now things are taking shape :) You can see my bracing, baffle lay-out. The matching stands are even coming together. The bracing looks a bit odd but seemed effective. I think that should leave room for the crossover on the bottom, I'd be to chicken to put it on the back for fear it would fall off.....

The parts will be here on Monday. Please Mr. Brown be nice to my package.

Progress on the RS Modula MT

2005-05-30T19:20:00.000-07:00

I got the baffle measurements from Jon and drew it out on the baffle cause I'm getting excited :) It looks like the tweeter would touch the woofer so I'll probably back off just a bit so I don't blow out that little piece....

>>>The tweeter center if 4.5" from the top, offset 1" from the center (for the EM; the Modula is offset 3/4" ).
Woofer is centered laterally; center is up 7" from bottom edge. <<<<

Cutting the baffles:
In the center is the home made template I use. The cut-out still needs some fine tuning after useing the template. a little sand paper or free handing the router seems to work fine. You could save your self allot of grief buy purchaseing the round version of the woofer.

This looks like a good DIY project to me. Will it work? I'm not sure, but the price is right..... Here's the authors full DIY page.

How I got started >

2005-02-26T22:15:00.000-08:00

Up untill about a few years ago I was listening to music through a set of 2 way Pioneers Purchase price about $130.00 Also a pair of 3way Radio shack speakers with a huge 12 inch woofer on each side. These came with one of these all in one stereo systems valued at maybe $1,000 (time of purchase) My wife would not allow these monsters in the living room. We also had a pair of small Radio shack speakers maybe 3 or 4 inch drivers in a metal box. One day I got curious about what was inside the box and thats where the story starts...

My first project was the D3s These speakers cost about $150 in electronics and maybe another $100 in MDF and Oak. When I completed this project it was VERY obvious that these speakers far out preformed any of my other store bought speakers in every way. At that time my biggest suprise was the Bass, I had never heard anything like it in a 2 channel home stereo, even those big ol' 12inch drivers in the 3way's didn't come close! Now I was hooked, as you can see here. Since then I've built the BR1's, D8mtm's, 2 Subs, 2 sets of DHT - MTs, The "More-Pees" and a center channel.

"More-Pee" > The crossover network

2005-02-26T18:13:00.001-08:00

Here's how the crossover looks, well kind of... Since this picture was taken changed a resistor and mounted it to a 3/4 inch board. I also glued the heck out of it, so now it looks ugly.

"More-Pee" > The assembled boxes

2005-02-26T18:13:00.000-08:00

You'll notice the box looks bigger than the one Wayne built and that’s because it is. The internal dimensions are about the same but as you can see in this picture I added a double thick baffle and double thick bottom. The Crossover board was also made with 3/4 MDF and put on the bottom so that also was a factor. (Not to brag) But I really prefer the look of my baffle :) Lots of great beefy looking Oak.

The Morel "drop-in replacement"

2005-02-26T18:03:00.000-08:00

As you can see by Wayne's web site the Morel MDT20 was not used in the original design. Some time later he came up with this and another option. After looking at his nifty frequency response chart and reading his comments I thought the Morel would work great for me so I went ahead with this option. This graph and commentary are no longer available on Wayne's website. (I got his approval for this graph & comment)

Wayne's comments:

"Overall, the Peerless 850122 + MDT-20, i.e., MorePee, combo sounds different from the D25, not better or worse, but different and certainly acceptable. The MDT-20 is a bit more refined than the D25 and sounds a bit smoother. The D25 appears to provide a bit more resolution. Either way, they both make for a very good system."

More-Pee > Building the box

2005-02-26T18:00:00.000-08:00

I found this walkthrough VERY helpfull. The Walkthrough is meant for the D3 but I think it's a usefull lesson for building speaker box.

"More-Pee" > Box, baffle and port

2005-02-26T17:56:00.000-08:00

Here's the start of my Morel-Peerless project AKA "More-Pee". This is the start of my project , I've been routing the baffle and installing the port
