Hi,

I have purchased a pair of BM15s second hand which were sold as seen.

I tested them and neither tweeter is working in either cab, although
the
woofers are fine.

Could someone please advise the best way to proceed, how can I check to
see
if the problem is due to the tweeters being blown, or if is is
something to
do with the crossover, possibly an internal protection fuse?

Any help or info on what may be the problem would be most appreciated.

Many thanks in advance,

Jon

ps I have been quoted £130+VAT per tweeter, if I do need to replace
them
does anyone know anywhere cheaper or if it's is possible to repair
them? Thanks

Pop the cover and look inside.

If the tweeters are good, there will be DC continuity across them with
a meter. If the ohmmeter shows them open, toss them out. If they
measure a couple ohms across, start looking at the crossover. Could
be a fuse on it, could be a cracked resistor. The ohmmeter will tell
you what you need to know.

Thanks Scott, just got to dig out my multimeter, and probably get a
battery for it it's been a while!

Thanks again,
