LS9 wiring / impedence question
« on: 3 Sep 2011, 11:49 am »
Danny or anyone else, how are the woofers a tweeters wired in the LS9s?
I seem to remember they are a combination of series and parallel, but i can't seem to find a diagram i once had.

I'm curious what the impedence is of each set of drivers as i voided my AV123 warranty (no laughs from anyone  :lol: ) by making my pair active.

Today i had an amp go out, and just got thinking about the loads each half of the circuit is working with.

Thanks,
Todd

Ps-glad i had a spare outlaw m200 from my set of 5. Total diagnosis and repair in 15 minutes!

Shoot me an e-mail and I'll send you a wiring diagram and an impedance curve.

Unless you have a measuring system and an active system that will allow a ton of adjustments within each set of drivers band pass, then there is no way you will get a reasonable response with an active crossover. Standard electronic crossovers just aren't going to work. They just aren't capable of dealing with the issues that the passive crossover corrects for.

Thanks Danny.

And yeah, it took some serious adjustment, but i've gotten things evened out to within 1 db (speaker and room response) the entire way from low to high rolloff points thanks to two dozen PEQ filters.

It was a lot of work, but i'm glad i tackled the project.

If you have a way to measure it and that many filter points then you can make it work.
