Btls Getting A Little Warm And Smelly

[Decaf]

sorry for stealling your thread but i was wondering before i blew my btl 18" new model i had felt the sub and its was really hot but it never smoked nore smelled. i felt it and it has really hot. but the sub blew from mechanical failure im runnign off a sudown 3000d with 7.5 cubes. where they supposed to get hot

personally it sounds like too big of a box for 3000w on that speaker... and a clipped signal

sub should really not get warm besides a bit over ambient if its cooling correctly

and what was the mechanical failure... smashes vc former or torn spider or tinsel breakage

If it was hot and didn't have anything decaf listed above then it was thermal failure.

I dont know what tempature the btl coils start to let go at, but most beefy subs can withstand up to or more then 500 degrees (atleast this is what dd told me about my coils), at that point this is when the glue starts to let go that is holding the coiling wire onto the former.

i love the sound of the voicecoil scrapping against the gap...lol... isnt that what they mean by mechanical noise... rofl

as long as it isnt too bad

if you play it long enough, it wil go away.

By any chance did you accidently join one of the voice coils into a loop on each sub (positive joined to negative)?

It sounds like you might have, this causes the coil to actually induce a field backwards against the excursion and limits the movement of the sub. Some people do it deliberately in SQ settings (mostly home theatre) as it also increases the sub's control over the cone.

So you would have been feeding a whole lot of power into a single coil and at the same time limiting the subs excursion and thus the ability to cool itself... sounds like a good recipe for lots of heat to me
