Default KARLSON

-kinda made fun of them - until I actually heard one's awesome dynamics and got to know them a bit better - I've owned Transtatics, Maggies, Tympani 1D, Edgarhorn, Acoustat, Klipschorns and piles of boxes - Karlson have been the most fun and most powerful sounding for their size.

since Google uses tracking robots to determine possible copyright issues, it would take a public domain track. I don't feel well enough to try to multitrack and it wouldn't be so good anyhow. There's probably obscure modern material which would slip through but that's too much of a chance.

here's a site with free to use music http://musopen.org/music/piece/840

I have not visited the Karlson in a while but they always look good.

OT: not many reports from Bill Fitzmaurice but maybe the thought just came seeing the Karlson in a music setting.

I had a baby Karlson sample build going at one time but it needed something. The good news is I set the cabinet outside and somebody snapped it up-- maybe for car audio, who knows?

Greetings to the Karlson gang.

One of the few classic designs of that era I haven't heard. Looks really interesting...better for guitar than audio?

good for audio or guitar (Beta 12LTA is like a "big midrange" - a coax with 109oz magnet slug has more "snap" on transients)

moving mass might be a bit higher than I'd prefer but this is a decent size magnet

Depends on which model you have. I've seen Meathead using them in very large concerts for mid bass. They have an amazing punch in the mid bass with lower distortion than anything else around. They can reproduce drums at live levels with relatively little power and you have to experience it to believe it.

They are full range but can do with a bit of help from a tweeter. One of the more interesting behaviours is that it does have next to no "beaming" effect (your head does not need to be in a vice to have the stereo image). I prefer it much above a horn: it has similar characteristics yet is a fraction of the size for the same lower cutoff frequency.

Sound produced by these speakers carries far further than from any other enclosure I've tried.

We see the principles laid down by John Karlson utilised in microwave antennas and other fields.

Best driver/enklosure kombo I've hit so far in the fullrange category is the little SK8 w/ FF225WK. Only needs a little help on top.

I briefly tried Philips AD9710 in the larger K12 "Karlsonette" over a year ago and remember it being good, I'm currently revisiting this match.

I'm going to try a BetsyK in the SK8. Got the inspiration from Freddi.

Default Karlson OK

This is the best cabinet Ive heard. My father has build two 8" in the 70s, when I was a baby (I born in 1969). 40 years late, I build two 15" + 4" and one more 12" plus 4" (woofer/tweeter coaxially mounted), with separate amplifiers for woofer and tweeter (only TDA2006 with +-14V for W and TDA2003 for Tw.)., and the sound they gives makes an earthquake in my house, with only 15W total in the output stages.

The pic you post look to high, is a mod from yourself?

Had you tried with the rectangular window and or with the multiple slots upper exhaust, and which is the audible difference? Mines have rectangular windows.

Good job, boy !!!
