Howdy all,

In setting up my PSM I am on the fence about how to set the crossover and EQ settings on my Mmats in the lowers (601.4 models). The website says their frequency range is from 100Hz to 5Khz. When I set the crossover in the PSM to that they sound BAD. I mean real bad. I had run them for a couple of months without any capping of high frequencies at all, just a cut off at 100 Hz or so and liked them fine. I finally settled on capping them at about 15Khz with the high pass setting. Here is a screenshot of the PSM crossover tab, the Mmats are on the middle section with channels 3 and 4:




Also I added a mild EQ curve to tame the vocals and add a little bass. Here is a screenshot of the equalizer settings:




I am sure with my lack of experience these settings are not optimal, it's just what my wax plugged ears came up with. If anyone has any suggestions I would love to hear them.

Thanks y'all.

 

Look at ur plot. I'm gonna bet that with that slope and 4.1 at ur 100hz EQ band, ur digging way deep into frequencies that speaker cannot play. Ur prob crossing 0db at like 70hz. No bueno.

Use the plot. Lower ur EQ #s and use subtractive EQing. 4.1 is a bit aggressive. Qs generally below 1 unless ur specifically targeting certain freqs.

Hoyt, what does the rest of your setup look like?

Speakers, amps, etc

 

 

Dude, you gotta get out the crayons for me. What do you mean by plot? I think I understand needing to get 100hz reduced a bit, but what do you mean by crossing 0db at 70Hz?

Also I have not changed the Q settings, that's the way they were to begin with I think. How would reducing the Q numbers affect sound?

Haze, what would a good crossover setting for that speaker be?

Thanks again y'all.

 

 

if you boosted the 100hz 4db with a 12db slope that means you dont get to 0db on the slope until around 70hz

 

My problem is I don't understand slopes. I've watched a video about it but still don't quite get it.

 

Just take ur time and tinker with the program. Click on the Show Plot box and a graph/plot of your programmed EQ settings should show up. U can slide ur cursor around to see where the freqs & dbs are having an impact.

Without question ur gonna need to find the sandbox and wheelhouse of each set of speakers then after u get a feel for their stand alone sandbox dimensions then u can start to tie the sum of all speakers together.

Right now u have those Mmats trying to jam down in the 70s and all the complimenting stages in the world wont make them sound good playing that low, unless u just drown them out completely.

Take ur time brother. It will all come together.

So is the goal to hit 0db at your cutoff frequency?
