active crossove compatability?

[chucku 10+ year member]

I have a newly aquired 880 prs. I have 2 sets of MBQ reference comps. I want to run them active but A local installer said I shouldnt because those particular comps really benefit from theit passive crossovers. Especially the tweeter att and tweeter overload lights/fuses. I asked if they could set it up and dmm it for me so I know its set right and he said you need a o-scope to do it all right , even thought they have one they never use it, so no help there. Should I go active and does anybody know of somebody in the manchester N.H. area that would tune it for me? I guess I could do it myself if somebody talked me through it. HELP.

they are correct about the potential damage to tweeters. Not having an actual passive filter, any clipping will be seen by the tweeter as raw power. With no tweeter limiting circuit as well, there is increased risk if you insist on highest power levels.

filter tuning can be done with an RTA. because the desired quantity is sound, not amplifier output, the measurements should be done on SPL, not voltage.
