Hello XRK,

It sounds very good. For a desktop speaker, it is really awesome. It plays all genres of music pretty well. It is being driven by Allo Boss DAC on RPI and class D amplifier. I hope my nephew likes it.

Thanks
Balaji

Default Karlsonator 0.53's in wood

Hi Folks,

X has mentioned that more than one interested party would like to see some construction plans for a wood version. These plans were developed using Sketchup 2017, so it will require some familiarity with that tool to be able to pull out individual components and measure for size and the various angles. All components are 1/2" baltic birch except the front aperture, which is 3/8.

Could you "down save" the model to Sketchup 2014, please?

Here's the same plan saved as a Sketchup 2014 file.

Thank you Jan for providing the nice Sketchup plans for the community. It will helps many builders make perfect cabinets I’m sure.

For interested builders:
It’s important to follow the guidelines for adding melamine damping sponges and a sheet of foam core on the inside of the aperture for this speaker to sound great in wood. Don’t skip the damping pads step and try to ascertain sound quality.

hi X- would you give a look and opinion on Mr. Flexy's YouTube "Mini Karlsonator" ? - here's my post - I may not have the specs quite right by eyeballing but assuming the speaker works (?) then something must go on beyond the standard 6th order series BP model

Hi Freddy,
Looks like an XKi without an angled front chamber board. The vent looks a bit too large so perhaps the driver has a weak motor? Hard to say how it performs until I simulate it and without TS, sort of pointless. My guess is that the vent is to large (or short) and the front chamber too square. You will get a boxy resonance. Unless the thing is meant to work under 100Hz in which case, a Karlson aperture is not needed.

probably not worth your time - maybe at one of the Thai forums there's a real build (?) - ah - it does look better with a weaker motor cheap Rockville 18" but I have a hard time believing qts is that low on that speaker. even if Le is high. The magnet structure is listed as "109 oz" so maybe a 50 ounce ferrite slug
