Joe:
What I don't get is how he's turning dual 12" woofs in each cabinet into subs... those woofs are crossed over to mid horns. What's going to do "woofer" duty if he changes the woofer lowpass filter frequency in a 3-way?
Cheers,
Presto

I read that as he doesn't like his speakers and would like to use just the woofer sections. This way he could pair his "new" subs with another pair of speakers.
If I got that wrong, as Emily Litella would say, never mind.
:-)
...see, that's why I asked. I never thought of that!
I hope he chimes in again and sets us straight.
Personally, I would not use those as subs, but hey. In the spirit of DIY I'll try anything once! ;)
Cheers,
Presto
Thanks for all the input folks! Just to clarify, I didn't want to use the horns in the cabinet (they are a bit harsh for the room) & solely wanted to use the 12's as an additional low end to the system. It certainly sounds a little off, but had an extra amp & these monster klf 30's.. The current crossover points are much higher than I'd like to use these for & therefore didn't want anything above 70-80 hertz hitting them as they interfere w/ my other pair...
Thanks again!
Oh, well that's great then.
All you need to do is put an ACTIVE crossover "inline" between the source and the amp aka the pre-amp driving this amp.
This is instead of the PASSIVE crossover you were thinking of in between the amp and speaker.
You will likekly to get patch cords that will do Unbalanced to Balanced. Do not let the 3-pin XLR connectors on these units scare you - it's all do-able with simple "unbalanced" (RCA) to "balanced" (XLR) patch cords of the right type. The WRONG type could lead to hum and noise problems. Unbalanced to balanced cords for each type of unit are normally described in detail in the owners manuals of these things. Otherwise, guys here can help you.
Do not bother with the passive approach here.
Active all the way.
Cheers,
Presto
