    The person who cut my speaker pieces said that he thought the speaker was too small to need pocket screws so I didn't use them, but used biscuits instead. If you used pocket screws I expect you could use a short screwdriver, I think a small ratchet version would work best.

    Speakers for imperfect listening positions

    I'm in Rhode Island, Ohm is in Thomaston, CT (apparently they've moved from Brooklyn, NY), and they have a 120 day home trial. If you're near me you're welcome to visit.

    Speakers for imperfect listening positions

    I bought Ohm Walsh speakers for exactly that reason. My wife reclines on a sofa outside the right speaker and has full stereo.

    Would ZeroSurge or SurgeX worth it and would make sound worse?

    I've had power strips, both MOV (computer) and non-MOV (audio and TV), plugged into my Zero Surges for decades with no issues. I think the advice is in case you overload the power strip.

    Would ZeroSurge or SurgeX worth it and would make sound worse?

    I've been plugging power strips into Zero surge outlets for decades without any difficulties.

    Reducing Number of Electronic Devices

    After a mention in another thread (which I can't find now) I tried a Bits Limited LCG-3MVR Energy Saving Surge Protector with Autoswitching Technology. With the sensitivity set on max, it switches when my Flex Digital is switched in and out of standby. So I've retired my remote control outlet...

    Small 2-way speakers with linear on-axis and power response characteristics (Scan Speak and SB Acoustics drivers). H&V off-axis measurements included

    @XMechanik, I'm about to assemble the crossovers so I'm looking carefully at the information you provided in your first post. Unfortunately, When I don't completely understand what's going on I was trained to compare all sources of information. From doing so it appears that C2, C3, and C4 are...

    I don't think it will materialize, I've moved forward independently. But I've found some resources that might be of interest: Baltic birch (18mm) source: Ocooch Hardwoods; the largest piece they supply is 23"x30", but this is large enough to cut all pieces for one speaker. Two of these with...

    Small 2-way speakers with linear on-axis and power response characteristics (Scan Speak and SB Acoustics drivers). H&V off-axis measurements included

    Thank you. That makes complete sense. It will avoid the “I wonder if I did it right” continuing question.

    Small 2-way speakers with linear on-axis and power response characteristics (Scan Speak and SB Acoustics drivers). H&V off-axis measurements included

    Thank you. As my multimeter cost ~$10 a decade ago I'm confident it's not good enough. I'll read more on REW's measurements, but I expect that I'll revert to visual inspections. After all, it's a simple circuit and I'll lay it out the same way. What could go wrong?

    Small 2-way speakers with linear on-axis and power response characteristics (Scan Speak and SB Acoustics drivers). H&V off-axis measurements included

    I appreciate the responses, but your objectives seem different from mine. You both seem heavily involved in DIY speakers; I expect the two Mechano23's to be the only speakers I will ever build. So, to clarify: My only purpose in measuring impedance is to confirm that I have wired two Mechano23...

    I'm thinking of using this approach to avoid buying something that I'll only use once: https://audiojudgement.com/loudspeaker-impedance-measurement/ Any advice or comments?

    You are the only person who has said they would participate. The model is available for download in my original post. I think it’s reasonable to call the group buy a bust. Thanks for checking.

    I had the same concern and asked him. Their BB is indeed a full 3/4"; 15 ply. He said that they had just received a shipment. I've read those comments and looked around on the web. From what I read (and I'm certainly not an expert), I'm ambivalent about radiusing the front baffle as it shifts...

    I sent Speaker Hardware (dot com, a/k/a SH) a Sketchup model of the Mechano23 speaker; I made three changes to @XMechanik's design in that model: Omitted the terminal holes; I expect purchasers will be able to drill what they want. ¾” (19.05mm) Baltic Birch instead of 18mm BB (which SH doesn't...

    You might try changing file extensions before zipping. This has been successful for me in the past. Of course the file extensions would have to be changed back before use.

    Mechano23 Open-source DIY Speaker Review

    Minor (?) discrepancy between two threads: In this thread the linked inductor is 0.33mH 20awg, 0.38ohms DCR, 11mm H x 45mm D vs In the telling us about it thread it specifies 0.258 ohms for L1. This similar inductor is 0.33mH 18awg, 0.26ohms DCR, 13mm H x 51mm (CA$7.99) This slightly more...
