Re: What I am trying to do

In Reply to: Newbie question: Any harm from removing 1.5mH coil? posted by tetsuo on July 5, 2005 at 17:22:28:

I am using a pair of Welborne Labs DRD300B SET amps and have a 3-way passive crossover to integrate these drivers:

-EV woofer, 8ohms, 80Hz horn, 1.5mH coil
-Vitavox S2 midrange, 15ohms, 350Hz horn, 5uf cap, 2.8dB L-pad
-Fane ST5022 bullet tweeter, 8 ohms, 1 uf cap, 2.5dB L-pad

There is also a subwoofer that rolls in beginning ~70Hz using an active 4th order low-pass filter and 5-6dB bass boost ~30Hz

I want to "optimize" this crossover network to extract the best these drivers have to offer, and remove components where it will do no harm:

- Remove L-pads from mid and tweeter (sounds a little brighter, yet "clearer" to my ears)
- Implement a 80Hz 1st order high-pass filter before the amps. The Welbornes have 100k input Z, preamp has 130ohm output Z. Use a .02 cap at the amp inputs or pre outs
- Remove the 1.5mH coil from the woofer
- Push the S2 lower ~1100Hz replacing 5uf cap with 10uf cap
- Experiment with other tweeters like Fostex or EV T350.

Does this sound like a good idea?

Thanks much.
