klam projector type with 8" fullrange

[freddi]

15lb of fury with $12.60 Sammi 8" diameter 2" vc speaker.
It would play maybe 8-10dB louder than this video as the preamp
didn't have sufficient gain that day.



Sammi 8 & Wild Burro's BetsyK


Up close the camera's mic overloaded but there were gargling noises present in the front chamber that can be heard up close but disappear
as one goes back.

If I understand correctly, asymmetric projectors go back to ~1961 when Karlson tried the little KR5 Rocket in a new position and the AP series included 6x9",
10" and 15" driver klams.

There was also a plan for a 12 foot device with 2-15". Jess Oliver took over the klam production in 1968.

I believe a passive K-tube supported over the dust-cap to pipe out some highs would help. (That would look ultra-krazy)

Karlson's AP100 and Oilver's Maga-clam apparently used a K-tube
waveguide with compression driver to augment Altec 421.

This klam is roughly a copy of Alan Weiss's Rocket. (Weiss worked with Karlson and holds I believe the only current K-patent) The rear chamber could be
a bit smaller to keep qtc and power handling optimum but parameters
are constantly changing with voice coil heating and position.

Video - it would play louder than this and further

here's Lars Moseholm's spl chart to 25M of the Weiss Rocket.
The little box at the lower right-hand corner represents the
elevated speaker.


a standard Karlson 8 might be more fun and the 12" with 8" driver I like
better than my Klipschorn

These 4th order BPs are just way too cool looking and I've been 'chomping at the bit' for years now to experiment with 6th order variants, especially since the advent of how well THs can perform, but this POS body of mine has other ideas.

POS would be me on good day - 14yr of sleep choking has me beat - oh well...

Did you ever try sleeping on an incline like I mentioned? It has helped me and some friends quite a bit with sleep apnea and one with reflux issues, though he's still wedded to Nexium.

yeah - for 20+ years - have to try to lay on one side (which is better?) - on back is bad - hands lost all color 5yr ago

Not good guys. Take care of yourselves, best you can.

Only 5? Count yourself lucky. I was in my 30s when my hands quit tanning and started peeling year round, so used a prescription lotion, but after I lost insurance it was so ridiculously expensive I have to make do with heating up Vaseline enough to work as a penetrating salve when it gets too uncomfortable as every lotion I've tried including Vaseline's doesn't work well enough for any length of time.

Dunno about sleeping positions other than what works for me, but there may be some useful info here or other Google search links: What's the Best Way to Sleep?

Thanks, but without the quality care I at least once had, AFAIK I'm stuck with no viable options but to suffer through it for another ~1.5 yrs until I'm eligible for Medicare and a semi-affordable insurance policy rider. Assuming of course our gov't. doesn't continue to take it away and/or up the rates to where I can't afford it.

'Asymmetric propogation' hm. I wonder how breakup modes are affected.
