EQ for Yorkville U15?

[gj00023]

Hi, for anyone that uses the Yorkville U15, I'm curious what EQ settings you use. Searching online I found that most folks talking about EQ'ing these are bi-amping them. I am not. I'll be using these outdoors with subs.

I'm using a DCX2496 to EQ them, so I do have parametric EQ available.

Right now I'm using settings I found on another forum:
highpassed at 100Hz; 24dB Butterworth
180Hz; -5dB; Q5.6
352Hz; -2dB; Q4
2510Hz; -4dB; Q2.5
4980Hz; -2dB; Q5.6
7970Hz; -2dB; Q7.1

They sound good (great even), but I'm curious what anyone else uses.

Do you wish to optimize the EQ settings? You could measure the frequency response on-axis and under various off-axis angles to see what EQ should help.

Yes, but I don't have a reference mic, so I'm interested in what EQ other folks have been using.

I'm not a typical U15 user: I bought a used pair, modified them, and use them tri-amped for a home set-up. I use them above 100 Hz, my x-overs are 300 Hz and 1000 Hz. If you want more info. They are great speakers, a poor man's Danley Synergy.

Hi, I'd be interested in knowing anything else you want to share about your settings (crossover type and slope, PEQ filters, etc.) I'm loving these speakers! I'm mono-amping the U15 and using another amp for the subs.

DIY 15" Alpine car subs for subwoofer: low pass 50 Hz 6 dB (default x-over in JRiver, not sure of type.); delay 0.1 mSec

U15 woofer: high pass at 50 Hz, 12 dB, low pass at 300 Hz, 12 dB; delay 0.1 mSec.
U15 mids: high pass at 300 Hz, 12 dB, low pass at 1 K, 6 Db.; delay 0.03 mSec.
U15 "tweeter": high pass at 1K Hz, 24 dB.

Note that I made the mid ports smaller (about 1/2 of original area) to make them more Synergy-like. Also stuffed with foam to make them Geddes-like My EQ settings are of course to my own "house curve" but here they are:

Freq, Q, Gain:
172, 2, -8.8
444, 5, 2.7
696, 1.75, 4.3
2482, 1.75, -6.6

This system was tuned as much as I reasonably could (with just REW as a tool) for use in a living room. You may end up with different settings if you are going to blast a room or field full of metal heads

Looking back at the first recommended settings you found elsewhere, and what I have set up my pair for, I find it interesting that we both chose cuts at about 170 and 2500, although different Q and cuts.


As for you having no measuring mic. Why not use your ears? EQ by ear such as with 1/3 octave pink noise is better than nothing. That is how I made my personal curve a few years ago. Now REW will use it as the house curve and help me find my EQ based on my measurements of my mutated speakers, listening room and preferences.

Somehow the idea of using pink noise and my ears didn't occur to me! That seems like a fine idea. It might be spring before I have these outside again to try that though. Thanks for all the info!

These are some damn fine speakers.

And Canadian! I am so lucky to have found a beat-up pair. It allowed me to experiment upon them to make them "domestic" speakers. I would be loathe to do that to a brand-new pair of U15 or Danleys (except probably the foam plug mod).
