Mini Karlsonator (0.53X) with Dual TC9FDs

[Skylar88]

Still listening to mine every day.

X, thanks for your effort in answering all our questions and simulating new designs. This amazing little speaker is punching far beyond it's size and cost.

Thanks to GregB for the original design and Freddi for his energy in supporting the revival of the Karlson. A big thanks to everyone who has given this speaker a chance and built it. Hope you are still enjoying your Karlsonator.

Wow. Brilliant.
So far I have only made the mini k from foam board but I love them.
It was my first diyaudio 'thing'.
Currently in use as tv speakers.

Also thank you to GregB and Freddi, but also xrk and everyone who helps people out on this thread.
It is fantastic.

I wonder how many pairs have been made.

 

[xrk971]

I would hope over a hundred have been built. Who knows for sure though.

Think I may make a set out of hardwood for my workshop, to use a pair of TC9FD I have lying around. Need a nice desktop size and they should fit the bill nicely, as the foamcore ones are getting a little dinged up from age. I now have a pretty good setup for woodworking so looking forward to the challenge

Hey X,

Revisiting after a long hiatus. The .53s with the Daytons are playing right now in the office and sounding great! I have built 1 pair of the .53s and i think 4 or 5 sets of the .4s for kids and friends. Great reviews all around!

The Cornus continue to start conversations at the hangar and sound amazing. Cutting foam got me thru the early pandemic and the results are still paying dividends. Big thanks to you and all the great people here for the inspiration and help!

if anybody is on the fence - just jump in! The value and fun factor is unmatched.

Any help with Post#4279?

Sketch up experts,

I can navigate around the views that jhofland posted in the sketchup file. One question: is there a dimensions window that can be opened, or do I take the dimensions from the published pdf for the jhofland design.

Thanks,

MM

I don’t use Sketchup but I would imagine there is a way to pull dimensions. Lacking that, just go with the PDF plans that are published. If your wood thickness is different, maintain internal dimensions. +/-3mm is good enough. Don’t worry it is pretty forgiving.

Thanks for the kind words, Pete! Glad you are having fun and the speakers continue to get compliments at plane hangar. Not too many people can say they made DIY speakers for their airplane hangar.

Thanks for the reply X. I thought that since the S-Up file was from jhofland, he might chime in. PDF measurements will work great.

Has anyone tried the dual driver Karslonator with the 8 ohm version of the 3FE25 instead of the 16? Any reason not too assuming the amp can handle it?

 

[xrk971]

You would have nominal 4ohm speaker and possibly 96dB or 97dB at 2.83v. It should work well if your amp can handle 4ohm loads.

 

[big russ]

Thanks, I have 4 X 8 ohm drivers already so will give it a shot!

Hello, I was willing to make the 0.40x karlsonator with a single tc9fd, because of how cheap it was on partexpress, only $9, I don't want to spend more than $40, but when I send it they charge me $65, to send it to Spain , how can it be so expensive?, I was amazed, there is no place in Europe where you can buy it cheap?.
Is that since I have invested, I don't know if it is better to do the 0.53x with the dayton PA130-8, any recommendation?
Greetings.

 

[pelanj]

How about here? https://www.soundimports.eu/en/peerless-by-tymphany-tc9fd18-08.html I can recommend this e-shop from personal experience.

 

[Skylar88]

Axiomedia.it in Italy is another option in Europe. That's where I bought the FaitalPro 3FE25-16 drivers for the dual 16Ohm 0.53x. Very friendly people and they sell the drivers loose, i.e. no need to buy a whole tray.

In Europe you can also order from THLP.

I got four from them shipped to Italy.

Best price so far this one, with shipping €42, I think I'll take these I don't think I'll find something cheaper, thanks!!

You are welcome, THLP had good prices on a lot of drivers recently.

I was recently gifted a pair of 3fe25 and thought that I would make a pair of foam board Karlsonators. I've been looking through this thread for a while trying to find plans for the cabinet. Is this one in the first post the plans for the single 3fe25 version?

Yes, that is the 0.40x size for single driver.

X has a Youtube video of it: www.youtube.com/watch?v=cL_twu7TEtQ
