    Re: The Quarks - M.O.S.D. Computer Speaker

    Being a noob I really appreciate the detail of the cross over schematic with the speaker polarity and input polarity clearly marked and the reverse polarity of the tweeter being noted. Dept. of redundancy dept. is ok, all doubt removed. I think a tabaq is a quarter wave tuned cabinet designed for tang band 3" full range drivers,.

    I might be asking something stupid, but can it be mounted in a Tabaq enclosure with that crossover!?

    I have the boxes from other project, also the tweeters and some crossover parts...
    I have no idea what a Tabaq is.

    So I managed to mount the founteks to the sphere. Ported using the PE 1x4. Without the crossover they already sounded clear and full. When I added the xover and tweeter is when they really opened up! I am amazed at how this setup sounds. I couldnt stop listening to them! I would describe the sound as detailed and engaging.

    The best sound I got from them was with both tweeter and woofer on the same plane so ill need fab some mounting for the tweeters. Thanks Jeff for a great design!

    i was going to try it out anyway and play around with tweeter placement before cutting. I wasnt sure if I would need to cut the tweeter off lower or higher

    thanks
    Since it sounds like you're going to be in the acoustic far-field I don't think you'll need to change anything. The original crossover should be fine.

    Yep, a fast faux finish. My wife actually said those are cute, she actually like them.

    Yours seem to be moving along as well. You will like the sound of these.

I just got all the holes drilled now I just need to search through the supplies and see what terminals I am going to use, then I will be ready to assemble. It will have to wait until Sunday at the earliest.
    These speakers are fun to build in that everything can be done with calipers in hand; not something you usually get to do in the wood shop but it does seem to make the build go faster.

    This shows how small they it has a pencil/quarter for scale. You can also see how I did the joint work on the cabinet.

ID:	1165760Oh Gosh, Jeff these things are really special, but hey you know how to design, no doubt. Got the finish completed last night or this morning at 1:30....had trouble with the ports then I realized I was shoving them in the tweets holes...what a sleepy head. Anyway I started listening and couldn't stop....just couldn't, but finally fatigue fueled eye closure! Gail and I were gone for the day, but I fired them up awhile ago and I am so amazed, so I will include a pic, but I will start pic thread here!

    How would the ND20fb work? I assume that I would also need to flush mount the woofer to keep it on the same plane as the tweeter.

    The little speakers sound great driven by my receiver and everyone loves them. But I was a little disappointed when I hooked them up to the computer through the Topping amplifier. It may be because I have the Topping plugged into the audio jack on the computer. I may need to run it through a USB DAC and bypass the computer's sound card.

    Woodsart, I picked up some hammered spray paint that was on clearance. I have used this before and it holds up great but I think i will be building more then one pair of these. Other wise I will have a lot of leftover mdf scrap.
