Members Dookietwo Posted August 3, 2015 Members Share Posted August 3, 2015 Had a day off so I did some measurements. Some say these subs boom too much so I wanted to see if something came up in the response. I will post a few replies so wait until my wrap up should you have a question. First pictures are the setup and settings on the back of sub. Tops to be used are EF500p. I use their built in 100 hz cut. The subs are center clustered for the most part so I have them go up to 120hz ( 6db down point ) to help fill in. Link to comment Share on other sites More sharing options...
Members Dookietwo Posted August 3, 2015 Author Members Share Posted August 3, 2015 The response is just as it should be with the spec's supplied by yorkville. 6db's down at 45 hz and a flat response through the subs range. Next I moved the shape knob to Deep. This gave a 6db boost centered around 50hz. I found at 12 o'clock it still had a 3db boost. So Loud on the Shape setting has the sub working flat. Maybe this is the boom some talk about? Link to comment Share on other sites More sharing options...
Members Dookietwo Posted August 3, 2015 Author Members Share Posted August 3, 2015 Last I added a cut with my parametric on my yamaha 01v96. Q of 6.3 and a 5.5 db cut. This gave the sub a 6db down point of 38 hz and it sounded solid and deep. A flat predictable response. I'd watch the loud setting on the shape knob as it adds a lot of energy at 50 or so!

Members Dookietwo Posted August 3, 2015 Author Members Share Posted August 3, 2015 Wanted to add that I added 3.5ms to the tops to get in good phase alignment with them sitting on top of the subs. With both top and sub with their inputs set at 12 o'clock the sub is roughly 6db's louder. Link to comment Share on other sites More sharing options...
Members wesg Posted August 4, 2015 Members Share Posted August 4, 2015 Neat! That's great information. Yorkville doesn't tend to document exactly what some of their knobs do - see the recent NX10C thread. I'm guessing your mixer has an RTA of some kind built-in? That must be handy as heck.
