Speaker magnets
@jasonbourne52 I have a pair of 8" Kevlar speakers with magnets that are 2/3 the diameter of the speaker, so presumably they will be better at low frequencies than my pair of 8" vintage Wharfdales that only have around a 2" diameter magnet, or is it more complicated than that? I can’t test as they are just the speakers, no cabinet. The reason for the questions is that I have access to a variety of speakers from 8" down, and thought I would do some reading (well a lot) and have a go at building some of them into a cabinet just for the fun of it, then experiment from there. |
I have a pair of 1980s Gale GS302 speakers that have damaged woofers, the tweeters are okay. They are a two way system + a passive radiator. I have stripped them out and they are made of nice thick material with plenty of bracing and doubling up inside. I may go with them for a first project, I have had thoughts about them before. I had a plan to fit a midrange where the passive radiator was, but inside its own isolated stuffed tube, somewhat like the B&O S45 II. Then make a cut out in the rear and fit a modern passive radiator at the back. Use the 8" Kevlars and a pair of 6.5" for the mid range, then connect them up with a decent quality crossover unit. They would look a little odd as the woofer is mounted in the centre. That means it would go tweeter, woofer, mid range from the top down. I have no idea if swapping the normal woofer mid range layout would have a detrimental effect. |
I’ve been quite busy over the weekend :^) https://cursorium.co.uk/speaker-project/ More work to be done. |
