im sure lots of people have seen my setup, well here in MI lately every morning its about 15* every morning, well is it safe to run my subs or is there arisk of cracking them or damaging them at this tempature.

 

As long as you run them real quiet for a few minutes, to allow them to warm themselves up a bit, it is quite safe.

 

That goes especially for fluid filled speakers, like tweets and dome midranges. Some subs are even fluid filled and need at least a few minutes to warm up before the oil inside can properly lube things up and keep them from blowing up.

Orion had a problem with their fluid filled subs about 5-6 years ago because of this and ended up ditching the fluid filled sub market. Some of the very high end subs and mids are still fluid filled even today, so if you don't know, double check before you pop something.

 

yes exactly, my friend learned the hard way, it was below zero he came out to my house, told me to hear his new system he got in his car the day before, he turned the bass all the way up, and kaboom, they were gone, cracked them both right down the middle, we figured it was from the cold, too bad no warrenty, thats what happens when you buy someting off ebay

Just dont forget to get them going for a few min before you push them

 

i dont know if my subs are fluid filled, well as long as its ok to play them low for a few first then i guess you answered my question.

 

I haven't seen a fluid filled sub for years. Orion is the last that I'm aware of, and they pitched it because it sucked. It lowers sensitivity considerably, and manufacturers found that venting the pole piece is cheaper, more effective, and has less negative drawbacks in relation to the performance of the sub.

Some mids and tweets still use ferrofluid, but I'm not aware of many. When fluid filled speakers were all the rage, a lot were advertised as "fluid" cooled. What they failed to tell you was that their fluid of choice was good old fashioned AIR.

 

IIRC, the new EL series from Bazooka has the option to run some type of cooling fluid through it. I'm not sure if it actually does any good unless it flows by the voice coil.

Well I went and looked it up.

Here's what their website says.

CHIL
Liquid Cooling Kit
MSRP: $249.00
Bazooka’s CHIL products improve performance by removing the most damaging element in mobile electronics—heat. The CHIL kit consists of a pump, fittings, hoses, and a specially designed Bazooka radiator that is an easy screw-on addition to the Pro2O series amplifiers. Additionally, the CHIL kit may be used, with the addition of the CHIL Plug, to liquid cool the new EL Series Component Woofers. Kit includes 15 feet of hose, 4 fittings for use on P series amplifiers, Pump, and CHIL resevoir.

 

that's just marketing BS from bazooka. The fluid cooled speakers that we're talking about surrounded the voice coil in a substance called "ferrofluid" in order to draw heat away from the coil.

 

I know that, and you know that. I just wanted to let others who don't know that there is other forms of fluid that can be harmed by cold temps.

Isn't that what this thread is about?

 

um i just wanted to knwo if id mes smy subs up if i turned them on in 15* weather

 

You aren't the only "others".

 

what? i dont understand???

 

I don't know what they are fighting about, but let your subs warm up. I live in Northern Illinois and it's super-cold here in the mornings, too. I never turn mine up really loud unless it's been warm all day, but you can turn them up like you normally would if you just play them low for five minutes or so first.
