PWK Rebel

Recommended Posts

Hi ... I have plans and patent papers for the Rebel, if I have name

correct. The 36" tall backloaded corner horn circa 1952. I got them

from someone late in 2004, but lost contact. It does not conform to

standard corner horn configuration. I believe I was told there was a

reason for a large chamber between the throat and the corner. I wonder

if I should scale up a Shorthorn (which has a tighter throat) instead.

Does anyone have a working knowledge of either?

Gil-

Thanks for posting the interesting article.
<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

At the risk of beating a dead horse<?xml:namespace prefix = v ns = "urn:schemas-microsoft-com:vml" />, its noteworthy that, in the article, PWK stated, . . . we prefer public-address type compression units . . . [1] He used the PA designation without implying anything negative about the preferred drivers.

Thanks, Guys ... Very much appreciated. Does anyone have an opinion on

a scaled up version of the Klipsch Short Horn, or two stacked as

designed per corner? It was in production for years.

Some answers may be in your recommended articles. I will read right after Seattle wins Super Bowl.

Guess what state I live in? Not to cool, but birds poop on steel

workers. Not one interviewed sports personality said one team could win

if they score more points than the ther team, weird. Sorry for

interruption.

Are there other bass cabinets that will rival the K-Horn? I swore

never to build one again. It takes a 12 step program to get over the

ordeal. I am trying to get as close to the "King" as possible. Not much

will keep up with my horn-loaded P.audio coax 12's (see below).

Imperials always come to mind, but big. No experience with them.

Hopefully something not as big, but must consider everything.

Would like recommendations for 12" - 18" drivers for what I believe

will be a back-loaded horn, or whatever other type is

recommended. Pi horns? Have my doubts.

For anyone interested, mock up a short straight conical horn for most

any mid driver you have lying around. One front one rear, 60 - 90 deg

four flat sided. Cardboard is good for quick check. Advantage,

perfectly linear cone movement. Open baffle with balls. I have never

seen this done, but I don't get out

much. Zene.

I agre that PWK backed away from this design. Others picked up on it, at least using a back chamber and then feeding a bass horn.

I'll have to look but I think there is something similar in this months AudioExpress, by Bill Fritzmaurize. It is not the same horn geometry. Rather it vents to mouth at floor level after a fold or two.

Another example was the Impulse horn by a British outfit. It also vented to the floor level. This one used a conventional midrange driver mated to a wooden horn. This mid is somewhat similar to Bruce Edgar's. It uses a conventional tweeter.

The British reviewer said it was the best speaker he had ever heard. (OTOH, he had moded it himself and had some unkind words about various aspects. This must have annoyed the manufacturer and they were not in a position to gripe.)

The very famous Tannoy Westminister is a back loaded horn.

It does seem like the Rebel / Shorthorn has limitation in bass extension. Stacking them may not help that very much.

If you want to build something, the Jubilee is a good option. One of our buddies here has posted detailed plans. It is far more easy to cut than the K-Horn and about the same trouble to assemble.

Take a look at an E-V Aristocrat. It's a back-loaded, folded,

corner-horn built under a Klipsch License. Mr. Paul *may* have

designed it. It is intended to be a 3-way system in its ultimate

form, but one and 2-way versions were built.

The bass horn is longer than a Shorthorn, so it should go deeper.
