Very nice Instructable, Gio!

Is there a quail in the picture of the 7th step?

This Instructable would be even better if you manage to make sharper pictures. Here is an Instructable on how to do that quite easily: https://www.instructables.com/id/how-to-take-great-photos-with-an-iPhone/

PS: ...and I'm looking forward to your next Instructable, Ivy. Thumbs up!

Dear Mr. Robbe Jansen, that looks like delicious lavacake to me.

Hi Bas, you made a nice snowman indeed! Can you explain how you created the snowman's hat?

Nice cookies, Marieke! I think these will taste even better with lots of icing.

Hey missy RGietema,I'll try to make these at home, thanks for the recipe. Can I use vegetarian frikandels as well, you think?

Well done, missy Gerritsen!

Wonderful!

For my speakers, the first thing to upgrade would be the Visaton FR10's. Tang Band (aka TB Speakers) has a series of 4" full range drivers (the W4 series) that outplay the Visatons, but it comes at a price. Have a look here: https://www.parts-express.com/Search.aspx?keyword=...Second best upgrade would be the capacitors in the filter. Audio-grade cap's start at around US$8,- but I think the improvement will be subtle.

Maybe I used the wrong word to describe what I mean. Tweeters, especially dome-tweeters, have a tendency to sound shrill or sharp. You can see that in the tweeter's frequency characteristics: The sound pressure increases as the frequencies get higher. An ideal tweeter would have a horizontal or flat curve, but most tweeters have an ascending curve.Hope this answers your question.Y.

:) glad you noticed.

Thank you, schaapkameel, it's appreciated :)

Thanks!

Particle wood isn’t that bad for prototyping and experimenting with cabinets in my experience. I made the final cabinets from birch, indeed.

:D Thanks for your overwhelming comment!

Ooooww, wonderful!

Wha! They look impressive. Great build, fantastic maiden I'ble!

As I read it, in the top left corner of the diagram the positive side of the two woofers and the tweeter are joined and attached to the positive input of the amplifier (positive sides of the drivers are marked with a dot).

Thanks for the tips! I found the skewed boxes improve the midtones, which agrees with your remark about the subwoofers. I tried both audio-quality PolyFill and pillow-filling as damping material, bit didn't notice much difference. I haven't tried wool, though.

Thanks :) I made the final cabinets from 18mm birch multiplex. Those sound fine :). In general, heavier cabinets are better. What you want is cabinets that resonate as little as possible with the acoustic energy and sound waves from the drivers inside the cabinet. So heavy 20mm teak wood sounds like a good idea to me.

Hm. I hoped my Instructable could boost Makers of both sexes into speaker building blissdom. I wonder why you choose to depend on your boyfriend to get yourself a fine set of loudspeakers, when you most likely can make those yourself :) x

Thank you! About the oxygen free copper: My understanding from the local electronics supplier is that an oxygen free cable last longer because it takes longer to corrode...

Thanks for your great comment. Boosting speaker-building morale was exactly what I was aiming for :). Please post some pics when you made something tangible / audible. Or if you're in need for advice...

Hi Schreib,Thanks for your kind comment. Some answers to your questions:1) Yes, you can glue wedged faces against cabinet panels to get the same effect. But if you can get access to a table saw, building skewed boxes isn't very hard. Just tilt the saw-blade and make sure the panel you're sawing isn't "upside down".2) I don't have the tools to measure the freq. response of my speakers, but hopefully I'll have them measured soon (within two weeks). If so, I'll add the diagram in an extra step.One FR10 driver can handle 30W continually, so the max. input of my speakers will be around 100W, I guess.3) I compared my speakers to a number of high end DIY speakers at an audiophile hifi gathering. My speakers can't compete with the high-end biggies, but still sound good. The biggies just…

My speakers can't compete with the high-end biggies, but still sound good. The biggies just sound even better. When it comes to the quality : price ratio, my speakers win :). But for many hifi enthusiasts, that ratio is not a criterion :D4) Yes I did. I put some pictures of those meetings in the I'ble. The experienced listeners appreciate my speakers, but would not build them for their own use. They demand more from a speaker than I do and are willing to pay the high-end audiophile price for that.

Thank you! That was what I was hoping for :)

Horribly good. The daunting task of writing a horror story lies ahead of me now. And that, dearest ElkeMa, is because you wrote this Instructable. So I hereby blame you for all the hours I have to spend writing a tale of horror. For children to read and shiver by.

Completely adorable!Y.

That is one lovely maiden I'ble!Thanks for sharing :)Y.

I like the supercap-solar panel combination. Does the Vibrobot dance in direct sunlight? And how long does it take to fully charge the cap with the solar panel?Pretty project!Y.
