Help modifying a 2-way amp

[joeybutts]

Hey gang, I bought an amp a bit ago and am hoping someone can help me mod it.

The amp is a 2-way, and the crossover is at 3.2khz. Is there a way for me to cut out/lower that crossover point for the "Tweeter" so that I can use a speaker I already have? I would love to make this amp the sole source for the weight room system if possible.

Also, if there is a way for me to lower the "Woofer" crossover too so it didn't play so high for the sub, that would be great, though I do have a means of fixing that if it isn't possible.

Thanks for any help!

The page you refer to cannot be found. So hard to tell what to do. Depending on the complexity of the filters it would probably only require some resistor changes.

By the way a typical two way cross-over is not meant for a sub-woofer, it is meant to drive a bass/mid unit and tweeter.

Do not cross-over the tweeter at frequencies lower than that specified you will break it physically.

Thanks Nico. I was thinking it was only something like a couple resistors, but that's about all I know.

Try this one. http://www.hafler.com/techsupport/pd...7_TRM6_man.pdf

I won't be using a tweeter and woofer. I'll be running a full range driver on the "Tweeter" portion of the amp and the sub on the "woofer" section.

It's only for my weightroom so I'm not really concerned about fidelity to an extent.

Thanks for helping! Let me know if that link works out.
