    6" Full range Magnavox Hi-Fi driver vs 12 Celestion Guitar driver .

    Thanks for your reply mate .. I wrote to Ted Weber and got a reply.They suggested an 8A 100 or an 8A 100T .. They sounded good but with the exchange rate and International Postage,the price was AUS$187.00,which is a bit much for me at the moment so I'm going to use the Celestion G12M Greenback...

    6" Full range Magnavox Hi-Fi driver vs 12 Celestion Guitar driver .

    G'day all, I've just purchased a One watt all tube Guitar Amp ( Wangs VT-1H) and need to make a cabinet.. I like the idea of keeping things small and using the Magnavox in a small cab to sit on the desk,but a few people have said that because it's a Hi-Fi driver,it won't be suitable.. even at...

    Checking a crossover ?

    Success.... The tweeters are now working well.. I re-soldered the posts on the tweeters and still .. no go... The problem turned out to be corrosion in the 'junction box' where the wires exit the cabinet and join the wires coming from the amp.. :( ... I've been using a liquid flux for all my...

    Grille Cloth Frame

    G'day friends, Just thought I'd share with you my idea of a frame on which to attach some grille cloth.. It's looks as though it'll work OK and I plan to staple and glue the cloth to the frame and attach it to the cabs with a little piece of Velcro at the top and bottom. The cabinets for the...
