LP@40hz for the mids dangerous?

[Slaugh 10+ year member]

i have these visteon component speakers and i bypassed it's original crossover by using 3way mode on my hu.... but i never foudn out at which hz the mids were being cut at on the original xover, since theres nothing written anywhere and technical support doesnt know this information //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif ...

so i just picked 40hz for it, but im afraid now coz at high volumes the mid excurses like a ***** and it smells like burning rubber easily too...

what would be a good and safe cut for a mid in general? thanks

I assume you mean highpass, rather than lowpass, correct?

Anyways....try 60hz-80hz. Should be a little safer if it's having problems @ 40hz. And use a steeper slope if necessary.

I'm no expert, but that sounds bad! Listen to teh Squeak.

not too many mids are able to handle a cutoff of 40hz with a shallow slope. The lowest I ever had my mids were at 63hz on a 3rd order slope.

Lol yeah...must have meant highpass. I'd recommend AT LEAST an 18dB/Oct slope at around 80hz...

crap... i made these cuts when i didnt have a subwoofer so i could get some bass from it... now i realize i dont need this cut anymore.. thank you guys lol

it was being cut at 40hz@-12db/octave rofl

now it's 63hz@-18db/octave, is it good enough? i still get satisfying bass from the mids without corrupting the voices heeh

It largely depends on the speaker, but lots play well down to 63hz, and if you get good midbass there then run it. I run mine down to 63hz now, but a lot of mids don't like playing that low. Also, typically the lower you want it to play, the more power it will take to do it acurately.
