Hi All,

Quick question ... I have read the advice here to add a protection cap to my tweeter when using active Xovers AND amps after ...

Does this still apply if I have the MS-8 powering the tweeters from its internal amps??

I am ready to fire the processor up today and don't want to fry anything :eek:

Some will say yes, others will say no.

From experience tweeters will survive playing the wrong freq, trun on pops and more IF the volume is kept low-so you can get away without the protection cap IF you are careful. (I accidentally hooked my MD102s to my midwoofer amp, which then turned out to have a turn on pop to boot, survied and still sound sweet, so double and triple check before going live!)

However it makes sense to put one in anyway, 50V non-polarised cap for 6dB filter on the power you have-higher voltage if you're palnning on putting a much bigger amp on at a later date, select a freq well below your crossover point-but above the Fs of the driver, typical recommendation is double Fs.

if you are worried about it, do it. it is $15 to protect your $100 tweeters and you wont hear what it is doing. just pick a non-polarized cap that is at least 1 octave below the x-over point.

I've been running it without caps but I know it's a matter of time until I screw up the setup or the MS8 freaks out. I keep putting it off but I plan on installing a cap on the tweeters. I was wondering if people install caps on the midranges as well?? I would burn the MS8 if it ever damaged my Dyns. All of my stuff is going through external amps though. Not sure if a 22w full range signal would damage a tweeter. It seems like it would, even one rated at 100w but who knows.

Thanks all,

I still have the factory speakers in place but didn't want to damage them with the initial start up ... I just made sure to keep volume low/off as I brought the processor online today (this is all new to me, I'm a bookkeeper LOL)

I am having some problems with my setup, and at one point thought I blew out the whole front right side of the processor/amp as that ONE door would not play ... but these are different issues and I don't want to sidetrack this thread ;)

Thanks again for the suggestions and I will be sure to add caps inline once I get the MS8 worked out

Michael
