Very much a noob question. Just wondering how hot crossover components can get? Is there any chance of damage from overheating in hot weather? I ended up covering my crossover in wool is there any chance of that being a fire hazard? Wouldn't be very impressed buy the sight of my cabinates burning up during a listening session lol.

Also my X-SLS build is complete as of yesterday really happy with how the duratex finish came out, moving into my new place with friends on the 10th so will get some pictures and do a bit of a write up then.

All the best from the UK

In 99.9999999% of cases: Nah you're good.
You're likely to encounter driver's distorting or burning out long before that point.

I would only be worried if you had large bass drivers with an in-line resistor in the signal path that can't handle the power load given to it.
Most times, that's handled by larger resisitors, or multiple smaller ones that will spread the heat load across them.

With the XSLS, that's unlikely to ever be an issue, so long as everything is properly assembled.

Morning!!

So, that’s a good question. I’ve yet to experience any crazy heat up cycles or that hot a resistor to melt plastic or ignite wool.

Plastic starts to get pliable around 220f. Auto ignition is around 550f or so.. (memory) I would be very hard-pressed to see a resistor get that hot. Warm, sure.. but to hot, I think your going to be ok.

It absolutely can happen... usually with an amateurish X-over design.
Using a resistor to drop the efficiency of a woofer can result in a lot of heat.  Not usually done, but I've seen student designs with that mistake.  I remember Danny told me he'd seen it in pro designs as well.

Hey!

   More likely that the voice coils of your drivers will burn out from over heating first. But I would leave the xover open with some air space though, resistors can get pretty hot.

Ah great thanks for all the quick replys! So I don't imagine it would be a problem with one of Danny crossovers haha!

I mean. I was thinking that… like a total crap network. But I assumed it was Danny’s stuff he was making note of.. again also assuming it’s put together right. So correction to me.. If like S.Clark said any of the above.. sure.. it could happen. My apologies. If your using Danny’s work and it’s all assembled correctly then the chances would be little. They would get warm for sure!!
