Hi

I have the oppurtunity to buy a pair of 4 way BIC Venturi Formula 6 Spec II
speakers from the late 70's. The are equipped with one horn tweeter, one mid horn and one coaxial woofer with dynamic mid-tone. Theese are in mint condition both technically.
and cosmetically. They look pretty advanced with the coaxial woofer,manual adjustments for mid/ treble, music style and the venturi bass port.

I'm intending to use them as speakers for a second vintage
system. Particularly for rock music.

I wonder if some of you AK'ers have owned or tried theese speakers.
Are they worth buying/ keeping ?

Appreciate your replies..

Ed

I used to sell them. Reliable, they sound ok, maybe a little bright. They weren't real expensive in their day. I wouldn't use them for critical listening. so, so power handling.

I've had a set of 6s since the 70s. Loved them but mine are NOT the SPEC II. I'm not sure what mine are. They are 3 way with twin tweeters, a mid horn and woofer. The popular ones are the 6 speaker jobs.

ANYWAY, for the right price, they are a good grab. I'm thinking $150 maybe $200. (hopefully much less). The fancy 6 speaker jobs will bring $400-$500 which just freaks me.

The thing with BIC Formulas. You will either love them or hate them. Seems like thats the way it is.

Had a pair of B.I.C.6's with 6 speakers... 4 speakers and 2 horns. I had them hooked to a Pioneer sx 1250. I loved them. They could easily handle the power of that reciever. Sounded pretty good too.

There are much better to be had, especially this time of year.

For the right price, and for what you want to listen to, I'd say go for it. I like my BIC's, they're efficient and sound good on Boston.

I haven't heard them in years but at the time I thought they were OK and thought they were better than many "audiophile approved" speakers of the time such as ARs, Advents, KLHs and such; I thought they had pretty good clarity and dynamics.

My opinion you understand. The important opinion here is yours; what do you think of them? ;)

Can anyone post pics of the original Formula 6 woofers?

I just picked up a pair of the 6-speaker models and I think the woofers have been swapped out.

Thanks,

Not the "Spec II" and they're the 5 and 7 (not the 6) but maybe these are helpful to one or another of the earlier posts :-P

I had these for a short while before I sold them . I was`nt that impressed . The mid was not original . I did build new grills for them .http://i893.photobucket.com/albums/ac132/butch4695/bics012.jpg http://i893.photobucket.com/albums/ac132/butch4695/bics019.jpg

Thank you for that!

Interesting, mine appear to have a cheap, rolled-surround Taiwanese replacement woofer.........and thus, have quite lackluster bass response.

The other drivers are all original. I have similar covers, but mine leave the Venturi port at the bottom uncovered.

BTW, you did beautiful work on your grilles! Though your phenolic rings were missing from the tweets.

I like the big, stout cabinets, maybe I can do something worthwhile with them.

E-WAVE ! They were very nice cabinets and I did`nt want to butcher them but when I had them I had never heard of the e-wave modification , and I only paid $25 for them so I did`nt have much to lose . Anyway I did make out pretty good on ebay but they were a bitch to ship .

I believe those are Altec Lansing, model 612, filled with Altec Duplex drivers, very nice speakers.

I'm highly impressed with the beautiful craftsmanship! and Thank you for sharing the pictures.

Does any one know of a web (site) that explains the inner working of the "BIC" venturi? Just curious.

Thanks in advance....

It was done by a process called photoengraving http://en.wikipedia.org/wiki/Photoengraving , that has been my occupation since 1979 . I can take any black and white artwork and make a plate like that .

I have a pair of those mid/tweet horn units like that pictured in the ad for the Venturi 7.
salvaged them from a big old set of BIC. Any good use for them??

I doubt it. I've seen sales flyers or owner manuals that showed a cut away view. (I own many pairs). Basically, there is a long opening in the bottom all the way across, there is a baffle that runs from the front to almost to the back. The bigger ones may have some "forming" that smooths the actual turn in the back. It's just a giant square port, more or less. I have a set of 1958 Knight speakers with Jensen drivers that are built the same way. The cloth accordian surround on the woofers made them bass "capable" (so to speak, IMHO, whatever). Given the time period they are from (late 70s), they were some serious rock speakers. They can slam.

I have 2s, 4s, 5s, and an odd set of 6s that is different than the two typical styles I see online (!?!?!?!). I have seen them called "sonic garbage" but they are fun.

blhagstrom...do you have any interest in these 6s that I have? I don't have much into them and if they have value to someone else, I'd hate to cut them up to make an Econowave or something else to attempt to get some satisfaction out of them.

Interesting to see this post here today. I just picked up a pair of trashed:thumbsdn: Formula 6's off Craigslist for free:thmbsp:. The cabinets are shot, but from the pair, I think I can put together at least 1 good speaker without too much effort and see if it's a project worth exploring.

There's a nice pair on e-bay right now, but pretty pricey ($549). The e-bay set and mine both have what look like 4 horns. I've also seen pictures of what looks like pairs with (2 horns and 2 cone tweeters: including the picture on this thread), instead of the 4 horns.

Just a bit fun during a lunch break, Max

Holy crap! I just learned that a handful of speakers I have laying around on the shelf are BIC speakers........

That is if BIC's EIA code is 310 and possibly 312.

I doubt that B-I-C made any drivers.
312 is Sylvania's EIA code (but that doesn't mean Sylvania was your drivers' OEM).

Hi
I finally bought a pair of BIC formula 6 spec II speakers in VGC. 4 way with 4 ellements. The seller borrowed me the speakers for testing. I paired them with my good sounding Sansui G 7000 receiver and the really impressed me. The treble was smooth and detailed.
The mids was very good with a lot of detail and warmth. the bass is
also good. Perhaps not the most accurate bass, cause I could hear some resonance. However I think there are some potential for improvement here. My pair has all the original speakers
as well as the original sound damping material. I think after 30+ years, the sound insulation might be sub-standard and should be changed. Thats what I intend do do now. I have allready cleaned all potentiometers, and everything
else still seemes to be working 100%. I have tried them on different sorts of music, and they do a really good job with reproducing horns, flute, strings, piano, human voice, drums etc. I have elevated them ca 5 centimeters and have them approx 15 cm from the wall. I tried them also on my old Accuphase 150 watt poweramp and it is worth to mention, that even if they are effective, they appreciate some extra power for better bass handling. I have a Luxman tube preamp with the Accuphase, and they sounded also warmer and richer with this setup. So I'm guessing that they will work terrific together with quality tube equipment as well as a clean/darker sounding SS gear with power reserves.
