Re: Maurbacs NS6 MTM

Wow! gotta dig that slanted top. Nice work.
With your woodworking skills, how are you going to finish them?
Thanks for the post, Looking forward to your listening impressions.

Haha, unfortunately I didn't do the woodworking, I'm at college so I did all the CAD work and sent off schematics for my dad, which he printed out full-size on his plotter and basically just trimmed along the lines. I think they're actually just going to be painted for finishing, because they're going to get beat up where they're going (my friend's house, lots of foot traffic in the area... carrying beverages). I'm going to leave them unfinished for a while though, some decision-making time.

re: beverages -
Yah, I was thinking about some [email protected]$$ crack about "slanted top? dude, where are you going to set your beer during parties!"

I may be a minority, but I don't think raw MDF looks bad. Slap a couple of coats of shellac or satin poly acrylic (or roll on some black truck bed liner) on them and call it done. The sound is what's important.

+1 on the raw MDF, but you definitely want to put some sort of protectant on them as MDF is mostly paper fibres, and if something did get spilled on them, it would ruin the cab pretty quick...

Re: Maurbacs NS6 MTM

For the last 2 or 3 years, my wife has been complaining that the dialogue on many TV shows is hard to hear.
We really don't want a HT setup, and just listen to stereo music and TV on our 2 front mains.

Well, it took a long time for the light to come on for me. Center channel! Not only did I know that it would
solve our problem, but I already had a good, cheap design for it. The biggest challenge was how to fit
it in a 6 inch vertical space in our LR entertainment setup. I had 22 inches deep to work with, and decided
to make it 24 inches wide. There was a very real question of whether a NS6 woofer at 6 3/16 inches could
work, so I make a baffle a bit wider and figured it "should" work out. In the end, I needed to do some careful
trimming of braces and some other file rasp work, but it all fit. Standard plywood box, 3/4 inch baffle,
skinned with the last of my maple veneer, and left as blond as possible to match the Ikea veneer.

I routed the driver holes before veneering, then found out why everyone says that that is the hard way to go.
Regardless, figured out how to route the veneer flush with the holes, and it came out as nice as I could have wished.

Wife says she absolutely loves it cosmetically, and it works great for TV.

Re: Maurbacs NS6 MTM

Did you change the XO at all for that CC? I've often thought of a budget 5.1 or even 7.1 setup with the Maurbacs and Aurbacs, but I don't recall ever seeing a CC mocked up by you, Don.

No, it's the standard Marubacs crossover (about 3dB BSC) - for my setup, with the baffle about 26 inches from the back
wall, and about 18 inches or so from the floor, it sounds pretty balanced. In the initial posts on this thread, I talked
about CC use, and measured off-axis response at several angles.

Re: Maurbacs NS6 MTM

This could be the sleeper HT setup of the year. I finally got to use a couple NS6's in the last boom box I built and I have to say they are fantastic drivers (just not the best looking things around). I could only imagine how good a Maurbac/Aurbac configuration would perform in an HT setup. It's definitely on my radar for next year. I just need one of my relatives to commission me for the build.......In the meantime, I WILL be cranking out a set of "mobile Maurbacs" for my tailgate setup. Thanks.

Aura NS6-255-8s will be going in the doors of my car at some point. In fact Madi sells a great little kit that I can't wait to get my hands on and put through its paces. It almost seems like the applications for this little driver are almost endless.

Re: Maurbacs NS6 MTM

I am doing something a little different with the Maurbacs. Should have pics in a couple of days.

Re: Maurbacs NS6 MTM

I just assembled my Maurbacs, well one of them anyway. I'll put some pictures up here later and my listening impression after breaking them in last night. Hint: They're awesome.

Love that smooth paper midrange, and the bass is not too shabby either.
so much so, even though I promised myself no more NS6 designs, that I'm thinking of a MTMWW with 4 NS6s and a tweeter.

Have you thought about using one of those DIY Sound Group smaller waveguides with the NS6?

I am interested in high-efficiency and low distortion designs and will probably build one or more. Probably not with the NS6 drivesrs though.

Re: Maurbacs NS6 MTM

donradick, I have used this to flush trim veneer with very good results, I also veneer after cutouts.
