Neal K Posted November 14, 2018 Report Share Posted November 14, 2018 Hi, I just registered on this site. I got my hands on a pair of AR 8bx speakers a short while ago. The previous owner had blown the tweeters, and I replaced them with drivers that I took oput of Yamaha NS 526. These are the ubiquitous 10 mm mylar dome that Audax made and that have been copied and used on many many speakers. It acually sounds prettyu good and I didn't modify the x-over at all. It is a simple 2 pole on the tweeter with a 3 uf series and a .20 Mh parallel. The woofer just has a one pole with a series 0.46. iron core inductor. didn't keep the originals and I do not remember the model number. Does any have any information on this model speaker, and possibly know which tweeter was used in it? This is a 2 way 6 1/2 inch AR 8BX. the other question I have is i looked at the crossover and it uses what appears to be a decent quality electrolytic and 2 iron core inductors. Will it make any appreciable improvement if I rebuild it with a poly series cap and air cores? The speaker sounds fine and look fine. I enjoy building speakers and on the other hand I am practical. There are four components in the circuit when you count the single 3 ohm resistor on the tweeter. Quote Link to comment Share on other sites More sharing options...
