dynaco_dan Posted February 10, 2008 Report Share Posted February 10, 2008 Hi Vern -Hi again;Well thank you for all of the photos.From what I can see you have a homemade or dealer made cabinet speaker system, most likely homemade.The drivers are incorrect for this particular cabinet, at least, as is with these woofers.The capacitor is Austrailan manufactured, possibly in 1965.The terminal strip is something a do-it-yourselfer would use.You have an 8 ohm tweeter and 2 - 8 ohm woofers, these are the correct singular drivers, as used in , the A-25's or A-35's only.The A-50 has 2 - 16 ohm woofers.These are not compatible as a set shown in these photos, sorry.This speaker will give you 8 ohm mid-highs and depending if wired parallel or series, the woofers will be either 4 ohm or 16 ohm impedance.The cabinet is sealed, it should not be, these are not acoustic suspension woofers.After all of this if you are happy with them, enjoy.If you are not happy with the speakers, parting them out will obtain the most money for you.Can you convert these into a Dynaco speaker system?Using one tweeter and one woofer you can create either a A-25 or A-35 speaker system.You would need to build good cabinets following closely the original dimensions and insulation capacity for the very best results.Material and labour will be high but it would be a project of love.
