its posted on the internet, it must be true.

Al- Have you measured the impedence vs. frequency for the K55M with and without horn attached? If so, is a post of it (graph, table) possible? (I'll take anything you've got, my signal generator is kaput). TIA, jw

AWG 12 is the default. I like Belden because the wire certs to the AMS standard for OFHC wire. The high temperature grade has a black flexible outer jacket that is marginally better looking than clear sw. Braided ribbon cable for the tweeters has physical justification, I've tried it, I can't tell. become a participant in an double blind test, you'll end up saving a bundle over your "audiophile" career. (what do you mean you "disconnected" the tweeter???) This message has been edited by John Warren on 03-01-2002 at 06:40 AM

is "Arturo Fuente" Spanish for mouth cancer? Taste's DO differ, I would like to keep mine (my tongue that is). This message has been edited by John Warren on 02-28-2002 at 08:44 PM

for some odd reason, that doesn't seem to surprise me. (can you supply some data to support your statement?) This message has been edited by John Warren on 02-28-2002 at 06:02 PM

go to site below, if it doesn't make any sense send and email to Arny Krueger and ask him. http://www.pcavtech.com/techtalk/wire_size/index.htm

Your comments, my responses- 1) Bose has an ENORMOUS budget available for R&D, market research, advertising and payroll. Where's the data? 2) Bose hires and retains some of the brightest engineers in the world huh? Again, where's your data Ray? I have old grad school buddies that "used" to work for Bose, nothing extraordinary. Engineers cycle thru Bose at a rate consistent with similar light manufacturing facilities in the greater Boston area. And, the word on the street is that Boston Acoustics in Lynnfield is the place to work, better salaries and benefits AND no auto industry ties. In the Boston area, salaries are the highest in aerospace/defense. 3) Bose is the largest speaker manufacturer in the world Wrong, it's Emminence. 4) Lots of people who buy Bose speakers are quite happy with the sound they paid for, which implies Again, unsubstantiated statements. Do you have any data to support these claims? If so then pls post. 5) Bose is very, very good at identifying a lowest common denominator of expectations, engineering systems to meet those expectations that are packaged in such a way to appeal to non-audio-fanatical purchasers and their significant others, and selling a sh*tload of product that meets the expectations of their intended market Where is this going? Bose is a medium sized manufacturer of consumer electronics. Seems like a complete waste of bandwidth to discuss their exisitence yet it comes up ONLY here on the LLC's site. No other BBS or NG discusses it.

A quick look at the back of this speaker reveals that the design is not a folded horn ala PWK. My bet is its more like a LaScala with the mouth exhausting to the back or a variant of an EV or Jensen design. The web site is a turd, leaves the "Normals" in the dark and the rest of us speculating. Regarding loosing your lunch over this-relax, the patent of the Klipschorn (which it isn't) long expired. Any half-wit with a tablesaw can go into business and make Klipschorn clones, just don't call them Klipschorns. This message has been edited by John Warren on 02-26-2002 at 06:34 AM

I have most of the Audio mags from '51 to mid 70's. They are bound eds I obtained from a universty library that was planning on destroying them. I pleaded with a nationally recognized university president (no less) to save them from the furnace. I even contacted members of the BODs. The irony of it all, I'm envoking preservation of a "Truely American Heritage" and he arged that he material was deemed to have "no intellectual content". In the end I prevailed, I became a "library volunteer" and assisted in "pulling" the journals from the stacks.

Thanks! I knew you'd appreciate the Klink post! C'mon, admit it, it IS funny, isn't it? BTW, I'm finished. This message has been edited by John Warren on 02-22-2002 at 11:11 PM

How low you have sunk! 4 the Record- I like JPS and Julian Hirsch (of whom I have met...Hirsch, not JPS of course). Hirsch was the founder of the AUDIO LEAGUE, a 50s not-for-profit that pulled no punches when it came to equip reviews. I have a number of the original publications including reviews on the National LEE Catenoid (that's a horn flare Mobile, try to keep up), EV Patrician, EV Cardinal and the Stephens "Fold-A-Flex". All of these systems would make JPS's weak in the knees. Long live JPS (he's really dead Mobile, that's just a figure of speech) Long live Colonel Klink (he's dead too, I just think he's cool) This message has been edited by John Warren on 02-22-2002 at 11:05 PM

Mobile says..... quote: I will be listening to a 300B amp soon...been looking forward to this since I havent heard a good 300B in quite awhile. Not since WE stop production in 1956 I'll bet? I certainly for one cannot wait for your review!!! Will you vanity publish it all over this board or will you subject it to a critical editorial review by a group other than teenagers? (I'll beat you to the punch.... "John, you mean like Stereo Review") Mobile says.... quote: Just to let you know, both tubes have their proponents. Please be more specific, you and exactly who else? BTW, thanks for this tid-bit, I wanted to know that piece of "insider info".

quote: Your Welcome, John. I'd like to thank you as well. Without your cheerful contributions to this forum, I would forget the true and unrelenting meaning of the words status quo. Now THAT'S a witty repartee! (but just between you and I, what does "unrelenting meaning" actually mean anyway?) This message has been edited by John Warren on 02-22-2002 at 08:38 PM

Hifi-Are you a retired store owner? What gives?

Ahhh, better "shucks"...you guys are so darn clever! Keith, Did you make that up all by yourself? Some good "big" word usage there. Mobile, Thanks, without your addendums to each and every post of mine I'd feel like I lost a pal (a 600 lb gorilla on my back). This message has been edited by John Warren on 02-22-2002 at 07:43 PM

I can't stand it! Let me catch my breath..... This message has been edited by John Warren on 02-22-2002 at 07:34 PM

Took some effort to find a distributor. This will certainly be an interesting mod. Thanks again.

Soundog- I doesn't matter, Beranack and later McIntosh Labs have shown that about 10% of the listening audience claims a sonic difference when no change is made in a blind test.
