Now I a`m ready with my life work
the supreme sound body`s
they have ticonal 9710 m01 type 2 philips in mint condition
these are Karlson couplers with horn effect
the first time I got a book in dutch on my 14th year
about karlson now I am 52 and they are ready
lots of rendament plenti bass overall soft to the ears
playing on se - el 34 tube amp new
I sort of unfolded the karlson box let it stand up straight
with the speaker in front in the top added a horn fragment
now I enjoy the results

the split is making a fase corection overall the sound
look at it as a tube with a split
a normal tube wil make out fased resonanses

Note that the most popular of the Karlson designs had the driver inside the box with a port/vent arrangement for the rear wave. The front of the driver fires partially through the slot.

for the ability to deliver useful power to the room the regular Karlson approach is one of the best (if not "the best") imo. For me there's little use in having "extended" low end frequency response with little or no dynamic ability = big piece of wimpy trash - a lot of music is dynamic and requires dynamic reproduction. (perhaps this can be measured with very fast RTA peak hold programs -?) for instance I currently have an 8" Peerless India woofer bought in multiples for Nelson's "SLOB" - 1-8" woofer topped with a helper tweeter plays "loud" but when the repeating drums come, there's no useful output or sense of dynamics and the direct radiator fails to couple to the air - hopefully 6/side will do something.
A regular little Karlson with 70-80Hz low end rolloff can sound more natural and agile than a direct radiator with "extended" small signal response and also do better than many horn. It takes some motor power, reasonably low moving mass in the woofer/fullrange and some watts. A "K10" size (~21"x15"x12-?13") should be able to navigate peaks to ~120dB. The slotted pipe waveguide sounds very natural and can be made for pennies.
Foirixi's rear-load K-coupler is quite striking and elegant in appearance. There's one US patent which is related to that layout (and of course the patent examiners missed Karlson's work...)
