  • The Reveal - Micro Bookshelf Speaker with Subwoofer

    I recently built a new set of Micro bookshelf speakers. My goal was to make something budget friendly and simple for beginners. SO I looked around for parts for a budget speaker. Here is what I came up with. I used the Dayton PC83-4 as minds and the Dayton ND20-4 for tweeters. The crossover is a simplistic 1st order crossover with a BSC circuit and a resistor on the tweeter. All in all the total cost of the build should be around $60 for the components. I am personally really happy with the sound. Check out the video for a quick build tutorial and sound test.

      Very nice design. They not only sound very nice, they look great too. Kudos!

        Yup, looks nice!
        Could you take a pic of the satellites next to a can of soda or something for a sense of scale if you get a chance?
        The white looks looks nice!

            Very nice work!

            It is this sort of stuff that really attracts newcomers to the hobby, in my estimation.

            The more we can attract, the more product we will find made available to us.

              First time I've checked out one if your videos, nice! With 4k followers you're on point for the ambassador program I would think. What's the alignment on that GRS sub? It looks sealed, I'd think it would need some boost and power to really get deep. Sent from my SM-G920P using Tapatalk

                Ahhh, thanks.
                It is smaller than it looks... for some reason I couldn't get a sense of the scale. Maybe it's the white that's playing with me.
                Good stuff.

                      Thank wogg! The GRS sub is sealed. It is definitely not for deep low bass. This is more midbass. It has an f3 around 50hz I believe. But something like it is really needed to complete a desktop build like this, since the speakers themselves are only good until about 120hz.

                      I am glad you checked out the channel. I hope there are projects on there you like. I am actually a brand ambassador for Parts Express So feel free to take a look at the channel, if you even have any ideas for builds around some of the speakers I have on hand, I am always all ears.

                        I couldn't agree more with your sentiments.

                          Good job, they seem really well matched with the sub. I'd be interested in a ported design.

                            They really are. I had a friend come over today to listen to them. I played a song and he instantly started smiling, as his eyes raised in surprised amazement. He started looking around to see if there were any other speakers. He even asked me if there were. He got up and waled around. They just do such a great job of enveloping the listening area, with no beaming at all. It really make a huge difference. He loved them. Afterwards, he said it really makes me want to sell my system and have you build these for me. And he was completely serious. Although, with a baby on the way, I am sure he has more important priorities right now.

                            As far as a ported design I'll look into making one. Although, I think one of things that really makes this so special is I am not asking it to do too much. However, I'm sure I could do one and we can see what is better. I am in the process of making 2 MTM versions (sealed and ported). The ported will be ported to an F3 of about 60-65hz. You can go lower, but need to make the box considerably bigger.

                            I am also considering a bipolar rear speaker design with them(sealed).

                            If you can't tell I am in love with this speaker combination. I am really impressed with these and could not be happier with the results. I would encourage anyone to try these out, especially on a desktop build with a small sub.

                            If you stay subscribed to this thread, I'll make sure to have the MTM updates soon. I think it'll be out after Thanksgiving. Maybe before, if I forgo painting it. But most likely after either way.

                              Happiness is sought after, but rarely sustained in this audio obsession. Enjoy it while you can. I'll keep an eye out for your ported design, thanks and enjoy
