Hi folks, I recently saved two wardrobe- sized cabs from being trashed. One is empty, the other one has the original speaker in it. It is a goodmans triaxiom 615. Here is what the cabs look like. (Of course we had to wire it up  )  The lower half of the speakers is basically empty, but I suspect they used to come with built- in tube amps. Here is a shot of the back of the cabs.  I noticed a funny thing, this speaker looks very similar to the one depicted on the cover of the original stalag 17 18 19 riddim sampler:  I'll try to post some photos of the driver and the interior of the speaker soon..... Can anyone tell me more about these speakers and the company that built them? I spent several hours googling, didn't find much. |

They are enormous..must be 6 foot high? i dont think they were anything to do with Goodmans themselves,i had an early goodmans brochure (1974-75) and they had nothing like that,but the triaxiom driver was in it....i suspect these were either a custom-built job for an early sound system back then(although the build looks to good),or more probually they came out of a small commercial cinema....from behind the screen. ------------- Be seeing you. |

thank you for your reply jbl man! 6 foot indeed! I opened the cabs again and made a few more pictures of the inside and the driver itself. The cabs are from an old recording studio, I haven't been able to find any information on them. Maybe something will pop up in the paperwork that is left, but that would be the proverbial needle in the haystack. here's a picture of the open cab from the front.....  ........and from the back.  The driver still mounted to the baffle.......  .....and unscrewed.......  ......and a closeup. This driver is just beautiful, a real work of art. The small HF horn is cast metal!  It seems goodmans was affiliated in some way with Tannoy, and I see immediately why  Shame I only have one driver  |

Looking at that driver,i would say its more like late 1960's. ------------- Be seeing you. |

Agree with Ian deffo mid-late 60's . I have not seen one for years. Used a few of the Axiom 150,'s but never got my hands on this one. Careful how much power you shove up it it will only be a few watts (15?) and for the comp only a couple. Tony p.s. Just found this http://yu-ra.tripod.com/goodmans/triaxiom.htm This is a later version when the modernised the chassis |

Definitely, would be a shame to grill this baby. I have to say it gives nice sound. The little metal cylinder probably contains a passive crossover. There is also a potentiometer attached to it with a long wire. It is for HF attenuation.

To be honest looks more like a labyrinth enclosure than a horn Tony |

That's probually an alnico magnet assembly if its 1960's Tony. I have to say,the driver is in beautiful condtion considering its age.Very good find Bob.Well done. ------------- Be seeing you. |

I think that 615 is a rare (and probably valuable) collector's item. Please don't blow it up. We used to have one in an original Goodmans cabinet with that crossover and pad, in a place I worked at in the 70's. It lived in the corner of a vocal booth and was used for playback. It sounded OK as far as I remember, but I've never seen another. It dated from the early/mid 1960's. |

Thank you for the input guys! Heck this is great but also annoying at the same time. What are the odds I'll ever get my hands on a second unit to have a matching pair? I still hope to get some hints on the cab. I guess Tony is right about the design, it doesn't have a proper horn flare. The port is also smaller than the actual cross-section at the end of the labyrinth/rear path.

When you think of how many driver manufacturers that we had in the late 60's. Goodmans and Wharfedale being my favorites. The Goodmans 18", Audium 91? was the first 18" jobby I ever played with, we had a couple and to be honest I did not know enough about boxes to get the best out of them. We had to recenter the magnets on our Wharfedale Super 12s almost every time we took them out but it was worth it. Tony |

Ditto that Tony,the very first drivers i bought were Goodmans 12PG's chrome-domes,purchased from Laskys for about £17 each new (the equivilant jbl k120 was around £90 then)...put them in some chipboard cabinets,bingo,first disco cabs. Likewise,the first 18" i bought was a Goodmans 18P,(a later model than yours,this would be about 1975 i guess)...i was excited as that was my first 100watt driver. Really well made and finished though...cost £35 new.It was on this chassis that Wembley based their B-line driver i think?
Bit of a shame,Goodmans seemed to lose the plot in the 1980's,concentrating on making cheap Dixon's type consumer hifi,and eventually just became badged up chinese rubbish,ala Amstrad.
I dont know if the name exists at all now? ------------- Be seeing you. |

A great find. I had 2x12's I built around '73 loaded with Axioms and Bakers. Then added a Goodmans horn tweeter. Saxon amp kits too!! Great days. ------------- Billy Dawg. |

Please don't mention the 12" Baker 50!! Almost every disco in the Black Country went out with Baker 50's in the early 70's a lot of them without any HF drivers at all. Jeez what a racket. No wonder our Wharfies, 401's with SME's and Leak* valve amps got us so many bookings. Tony * Honestly just poor working class kids but with taste. |

on the other hand maybe it's ok that I only have one, so mykey won't come down here and kill me this thing seems to be rare as f**k, the only old documents on the net refer to the 615 c which has an entirely different basket. |

that cab is a short and basic transmission line - if you listen to the port output it should just be the lowest notes. true transmission lines are very long and get smaller towards the port ( in fact, true lines end up closing up to nothing), i think the theory is that the line gradually absorbs the rearward energy from the driver, starting with the highest, shortest wavelength frequencies. This makes the driver "see" no rear box at all, hence giving very low cut off frequencies and no phase issues with rear diaphragm radiation at the expense of low efficiency and a large, complex box no good for modern PA, but superb for hifi - i have a pair of bowers and wilkins dm2 compact transmission lines from the early 70's as my hifi speakers at home, and for me they cant be beaten!

TL's... wunerfull!
I have the old Wireless World cabs I built too many years back. B139's still ok. The mids perished as did the tweets. Now has Hi Fi Beyma 8" and Audax HD13D34H tweeters. Sounds lovelly. Ratles the whole house.
They were driven by some of our own amps and pre-amp, now a Rotel pre/power. ------------- Billy Dawg. |

sounds good. My old dm2's came from a junk shop for £50 about 8 years go - inc the original receipt, boxes and manuals. They were in mint condition with all original drivers ( b&w 8" bass, celestion hf1300 mid, coles 4001 supertweeters) I bought them thinking they would be good for a second system - one week later my ATC scm20s with ATC sub were on ebay...
