HOBIE 1..... I have a pair of JBL 130B 32 ohm from a simmiler dual woofer horn... That are a better match... If your interested.. PM me. maron000@centurytel.net. Why are they a better match?[:^)]

Only have room for one of these monsters in my small garage.[] They would be very easy to build though. One of these years I hope to get a real house with a real garage....This BS of living in a subdivision with houses slammed together 8ft. apart, built using the cheapest of materials is for the birds.[:@]

JBL 2226H drivers..............won't be firing them up for a couple of weeks or so.[O]

seti....those are the same documents the guy used in his Ebay ad that he got from Steve Shell on the West Coast who loves the old theatre horns. I got the woofers installed today. Dizzy looking things over

This is the final resting spot, although I have the bass bin on a carpeted dolly for now until I get the JBL drivers mounted, then I'll install the funiture "sliders" since they are only 1/2" high. I'm looking forward to the day when I can fire up the system with the front mains consisting of dual Audax PR170MO high-eff drivers which will be 105db and then mated up to some Italian Ciare TW 1.38 tweeters which are also 6" in diameter and also 105db/1 watt. The mains will run from 300hz on up and the Shearer will run from 300hz down to 50hz where they will cross over to 2 separate Electrovoice 18" subwoofers in the loft area. You can see one subwoofer in the loft on the LH side near the cabinets. Amplification will be Crown Macro Reference which should be about 760 watts to each woofer with a damping factor of 20,000 on the RCA cabinet. I'll have a Crown Micro Tech 1200 watt amp on the front mains, and a Crown K2 on the 2 EV subwoofers. I'll use the amps in my HT processor for the side axis and the rear Clements surround speakers which have (2) 6 1/2" and (2) dome tweeters per cabinet. Coytee will be proud when I am watching the Blue Man Group DVD on the 110" screen through a system of 105 db efficiency...I might even match his level of slam his system has.[] I want that big-*** drum they haul off and whack with that big sledge-hammer mallet to be in the room with me or seem like I'm hugging the thing.[<)]

The Jubilee audition at Coytees led me to the JBL forum which exposed me to the Shearer horn. I then had a premonition that one of these things was still in the old theatre in my hometown in Ky. I had my buddy go to the theatre and sure enough they had just unhooked the original complete 1939 RCA speaker system. He told the owner that he wanted the speaker and would be back the first of the week to get it. This is a picture of how he found it. He went back 3 days later to find that the third owner had decided to throw away the field coil midrange drivers ( going for 3k or so nowadays), and the top horn. My buddy sped off to the county trash site to start looking for them. An old fellow said, " I saw a lady put that into the back of the trash truck and it was compacted and taken to the landfilll.....unfrigginbelievable.[:@] We ended up getting the bass bin and the original amp that drove the speaker. There was only one speaker all those years I was growing up listening to movies, filling up the whole theatre with the (2) 15" RCA field coil woofers and the horn setup on top. This is a pic of it upon removal My friend delivered it with a 7 hour drive to NC last weekend. It still had the 70year old dirt on it. I got it all cleaned up and painted it now and it will reside below the 110" projection screen in my garage. I've done alot of research on it and found some original drawings that were posted in a recent Ebay auction. I have found several people who have experience with these things and they are supposedly some chest slamming, mid-bass monsters that give some of the tightest, punchy bass from about 40hz on up. I have gotten (2) JBL 2226 15" woofers to put in it (recommended by a Roadie who used one of these touring Austrailia back in the 80's). I'll be firing it up soon and will be taking measurements with a laptop PC measurement system we recently got ahold of. I'll try to report back how it sounds.

He must also be able to buy mdf REALLY cheap.....wonder how many sheets were used for a pair of cabinets? An incredible amount of waste too.

Now we need to build them like this guy. It is a Tannoy Autograph cabinet.

Which sub would that be? Look familiar? Out several years before he made his version....unfortunately there are so many woofers out there ,that all of them are so close in design paramaters and cosmetics (since they put woofers together using parts from the same place.)....The days of going to the trouble to patent speakers are almost over... I'm not going any farther with this and stir up any crap.

Scott at FI did a great job of copying the desiign of another famous subwoofer on that one.[]

Hi Hobie dog-- One thing many people forget is that not everyone cares so much about making big BoomBoom thumping sounds with their speakers, and thus don't need megawatts of power. I sure do remember the time when the first and only important question I had about a system is "how much boom boom can she make?" The Bass-O-Rama days. As for worrying about "big balls" for instance, I am frankly more interested in the face, the hair, they eyes maybe, and not so interested in the "junk." In that case some smaller wattage tube amps like 60W or 25W or even 2W might sound "prettier" than some "hairy beast" if you get my drift. Yep, it does heavily depend on what type of music you are trying to reproduce in your room. I just read where all SS equipment produces 3rd order harmonic distortion which our brain tells us is not good and that tubes produce 2nd order which is what our ears are used to in normal life....ever heard that?

I liked the description, "NICE WARM & SMOOTH SOUND WITHOUT THAT CANNY 'HORN' SOUND "[:|]

Tubes are not for people who don't like to tinker and adjust them all the time. It looks alluring and plays with the ego to own tube equipment, but it's hard to understand some of the theory behind the small wattage, and being able to produce uumph for transients(some have humongous power requirements). I've heard several systems lately and when we switch from tubes back to more powerful SS equipment, the SS just has more balls. Brings me back to the old days of Bob Carver's amplifier challenge proving he could mimick the sound of the ultra expensive Class A tube amps.

The older I get, and the more audiophile events I attend, the more I realize I don't want to be an audiophile...I like my music too loud to be an audiophile.[]

Back to horns......[*-)]

And she was 3 months pregnant when that cover shot was taken...used to have her name written down somewhere

You could've had a V8

WAVAC is now offering a $50,000 monoblock amplifier which uses the 833A transmitting tube for output. It also uses a triode-wired KT88 for the driver stage. The highly praised (and soon to be in production again) Western Electric 437A tube is used for the input stage. Running in Class A by using Nobu Shishido's design talents this unit is capable of 100 wpc.! The chassis is milled out of a solid block of aerospace-grade aluminum. This is a capacitor free, directly coupled design for the purest of musical reproduction. If i was a rich man... WAVAC Audio Lab.

Richard: You nailed it pretty good. There's no way for anyone on the internet to fully understand( except you) the kind of sound I am seeking out of the Jubilee speaker. I already know that I need 4 of the bass bins in in my room, for just the type of dynamic slam Richard introduced me to....contrary to what anyone thinks about my room volume and SPL desires, because once again they have not been in my room with various speakers like I have. And I can bet that none of the people on here have years of playing with 18 piece Big Bands, Horn Bands, Orchestras as a trumpet player like I have. I have owned a SPL meter for years and am active in the car SPL/ SQ scene.. I've stuck my head in Alma Gates vehicle and experienced 170db before..I'm getting ready to be a judge at a Sound Quality event, so I have idea on what my goals are. For those who are concerned about my SPL requirements, 136 db peaks are just that, peaks, it's not the sustained levels that damage your hearing. It's for the occasional train wreck, atomic explosiion, cannon firing, that I want to realistically reproduce in my room. I always refer back to the saying, " Contentment is destroyed by comparison " You think your VW bug is the best of the 4 cars in your little town until a guy comes and takes you a ride in a 650HP Corvette. I read all the time someone says, " My XYZ brand subwoofer is awesome, it's a huge 12" model with 150 watts and throws 1/2 " That is their reference, we all seem to have a different reference. I said for years, " I've never had too much bass", then I experienced Alma Gates vehicle. I can only achieve this by constructing my own bass bin clones, financially. The wonderful thing about the internet is that for cheap guys like me who have not mastered the economic income system, can have access to the information on how to build things themselves. And if I can provide commercial venues with a great PA system for my A/V business, I'll be ordering the full Jubilee system from Klipsch, not copying it for my commercial gain. This system is just for my own house. The purpose for this particlar thread is to gather information on horns and drivers, as I will likely be making my own horns too. I would love to just get on the phone and order everything, but I cannot afford to do that at this time in my life, so I need to build everthing in this speaker system. Having 4 bass bins will give me the efficiency, slam, dynamics to make you blink on rim shots, as I have spent alot of time playing drums too, so I know what the sound is like sitting on the throne. I've only heard that punch from my friends really great system ( that has to be heard to be comprehended) and from being in the middle of the bands I've described above. I appreciate deeply Richard inviting me to his house and having me experience his system, as it has sent me on a new adventurous but affordable project. I hope one day to have him come to my house, and have a " Maxell tape " moment from my system[Y]

The other horn which looked like the best design of all is at this website http://www.acoustichorn.com/products/500/index.html A conical/radial horn. After reading about it, most standard horn designs seemed flawed. It was designed for motion picture theatre sound systems in China, for TAD components. Dispersion is 80 degrees horizontal by 40 degrees vertical. Low cut-off is 600hz

went to the Meyer and it was interesting to read about the development of the CQ series...thanks for you input.

Right, as I was looking at a 2" throat driver with different horns attached to it and looking at the freq response curves, to see how it affected the response.

Back on topic....I did quite a bit of research this weekend on the web and found out that mainly only the dispersion pattern is affected by using different horns on a particluar driver....yeah , before you start flaming me, there are subtle differences in the freq response here and there. So I found out that I like the 120 degree models and most of them are about 7" high like the one on the Opera M15 speaker shown here

It's called a "wife"......the #1 reason a set of speakers are either brought into your house or not.[]

Says who? You don't have a normal livving room, anyway. The MWMs will do 43 acoustic watts IIRC. You can stand them on end like the Altec 210 cabinets (picture of a modified single shown). Then they would only be 34 inches wide. That's what I plan on doing in my living room, but I will go with a single on each side. You can stand yours on end but they will still stick out 4 ft into your room.....they are a really deep speaker. Wouldn't work the way my RH side corner is configured.[]
