  • Neo MTM Build Log

    I figured i could start this thread, the speakers should be finished tomorrow evening. This has been a lot more than a speaker build for me, it was really a reinvention of my apartment workspace. It's very small, but these days a refuse to live without two screens. The majority of my schoolwork takes place digitally, and it's really advantageous to have the screen real-estate. Unfortunantly, having two big LCD's kills my desktop space, so i came up with a solution to that in conjunction with the speaker build, and it all kinda came together.

    The speakers were of course inspired by Chris Roemer's "Nano Neos," and much credit goes to him for helping me with the design of the MTM's, which i think i'll simply be calling "Neo MTM" for the time being.

    I'm terrible at documenting a project. Once i get going, i really don't want to stop. That was especially the case with this project, as i was using my university's student woodshop and time was often limited. The facilities are brand new (just in time for me to graduate, of course) are a really a thing to behold. I was really only limited by my time and limited familiarity with the vast number of tools at hand. Anyway, over the last week, i've slowly been getting things together, and today i finished cabinet construction.

    The front baffles are not yet attached. I can't get my arms through the cutout's, so i haven't quite worked out how the final assembly stage is going to go yet. :D

    So as i said, i had a deskspace issue to solve, and speakers to build. I came up with this concept:

    How was i going to mount that LCD up there? i don't know, i'll figure something out

    Well, a few years ago, i found myself constantly in need of an adjustable near field work lamp, so i built this:

    With a little bit of blood (and smoke from my ears) (and precarious LCD positioning) i ended up with this a few days ago: (sorry for the terrible picture)

    I was able to modify the base of my LCD and the lumber lamp to make a surprisingly sturdy cantilever'd mount. The lamp itself, if anyone's curious, is a cluster of 3 Phillips Luxeon 1 watt LED's powered by a cheap PC ATX power supply.

    Now, the speakers can take there positions on the sides of my screens.

    I'm not doing anything revolutionary with the speaker boxes, but i did want to give one thing a shot. I've used rubberized undercoating as a vibration dampener before, and thought it may be useful for adding some mass to the enclosure and deadening the internal sound a bit. So, i picked up a can of Duplicolor rubberized undercoating from Advance Auto and gave the insides a good 1/16". I've also got egg crate foam from PE that's going in there, and maybe some stuffing after the fact if i think it's needed. I promise to take my real camera with me to the shop tomorrow and document the final stages. I'll have more pictures up tomorrow or thursday! thanks for looking!

    So, i finished (structurally, not cosmetically) the speakers up last night and had a few hours to listen to them. Astounding. I have measurement no equipment, so the extent of my technical listening is reserved to test tones and music i (think) i know very well. They seem very flat throughout the range, with a peak just above tuning frequency. I keep getting the feeling the lower-midrange is just a hair muddy, so i will probably add some stuffing when i get around to it.

    The bass response of the ND105 has been really hyped up around here, and honestly, i was skeptical. I'm no stranger to large subwoofers, and i just couldn't imagine these things would be capable of really impressing me in the sub-60hz region. All i can say is damn. I was quite wrong. My tune seems to have landed almost exactly where i intended, about 42hz, which happens to be pretty close to the 8" 130w ported logitech subwoofer i have in my room. The sub now adds very, very little to the low end in the room. It's really quite incredible. Bass response is extremely smooth.

    Tomorrow the cabs are getting another coat of paint. I'll have a photo op then and post my results!

        NOW. they are a disaster cosmetically. I should have flush trimmed everything. i didn't even putty the countersinks. I should have made one of the panels removable. I SHOULD NOT have used 1/2" MDF, however well braced it may be. i hate the stuff. With school going on, i couldn't responsibly spend much more time on them.

        BUT

        to my ears, they sound great. and i had a great time building them. Someday, when i have my own shop, i'll build them some fancy new cabs. The PE brass spikes are great, however one of the feet WASN'T THREADED, which is why one of them is wonky...its screwed into the plastic next to where the (un)threaded sleeve sits. Thanks for looking!

          The MTM doesn't look so nano sitting next to your TV, unless that's a 19" tube... Good call on naming them the Neos MTM, adding nano to the name just doesn't seem appropriate. I don't mean to criticize, but those boxes do look really rough, I personally wouldn't have used the screws or nails or whatever it is that made the MDF bulge, wood glue is enough to hold the panels together as long as you have smooth cuts and plenty of clamps. Flush trimming would help a lot, too, it actually might look nice if you flush trimmed the edges now that the cabinets have been painted, the raw MDF would contrast nicely in my opinion.

          Are those supposed to be floor standing speakers or do you have something else in mind? It looks like the tweeters will be about 18" off the ground which probably isn't really the best place for them to be unless you plan on listening while lying on the floor.

            Hyper's got a particular use in mind, computer speakers for his vertically stacked flat panel monitors. The tweeters will be at ear level.

              That's right, if I'd read the first post I'd have realized they're going to be desktop speakers. The feet threw me off a little, I'm used to seeing feet like that on floor standing speakers.
