Brought them home, hooked 'em up, they made noise...so far so good, but
where were the highs? AWOL...crap, blown tweets! Not so fast....
Tested the tweeters with 9v battery--fine. Okay, time to open the box.
Pulled the surprisingly flimsy woofer from the 1/2" MDF box In
addition to the minimal x-over components (resister and cap in series
with the tweeter) was a #561 automotive 'festoon' style lamp in series
with the tweet. Shorting that brought back highs.
Now considering this was a series limiter, should I replace it, or just
bypass? The lamp

is a roughly 12 watt unit with apprx. 1000 hours rated life. Did it
'fuse', or just wear out?
Strange stuff, this Bose....
