The garage is 30x60 with 10' ceiling. The area where the audio is approx 28x30. Normally 8-20 people when we have parties, the music is primarily new music top 20 dance. I do have a meter and will get some readings as soon as I get home.

Some processors have a function called dynamic EQ. 

Employing one of these could enable you to roll off the highs when it reaches a preset loudness threshold.

I will draw your attention to the DCX2496 for example.

finally hearing the sound of a yorkville cabinet ay...the HF screams on those cabinets...lol but they still are solid boxes...

if you were going to look at the DCX2496, i would rather steer you in another direction of the Driverack PA+ from DBX. for $50 more, it certainly is money better spent.

I wouldn't be so sure about that.......

In fact, I wouldn't say that at all.

1. The U15Pís on sticks develop ear piercing HF at higher volumes (e.g. crash symbol) in the center of the room. itís not as bright/harsh on the right and left of the center clustered subs.
2. The bass output from the UCS1P is intense on the right and left flanks (which I like) but lacks that punch in the center of the cluster.


Your comment about lack of punch in the middle makes me think you have a polarity reverse between left and right.

The Db reading at the middle of the "sound area" peaks at 112.3db, didn't matter if I was LCR. Man those HF are screaming. I just don't understand they sounded so nice and clean before. I mean they are ear pierciing WOW! I am here because the orginal setup was designed by you professionals on PSW.
 

I have to wonder if those HF are reflecting off the ceiling since the tops are at the same height as before but not angled

We use the garage as a club and entertaining area. The ladies and teens think of it as concert or club setting so we like that intense volume and punch from the subs.

Any thoughts of changing the angle (rotate outward/inward) of the tops? If I rotate them outward I slightly reduce the "brightness" of the horns. But it doesn't sound as accurate.

Some more pictures to go with my sketch.

I can check my wiring, currently its R/L (XLR) out of the mixer into the tops, drop down to to outer subs then using the link into the middle subs. Before I did have everything wired into the subs then into the tops.

Thank you I will check it out.

The U15 have 60 x 60 degree (conical) HF pattern. You have moved them much closer together then before and now they are aimed partly at the ductwork.

Yes it looks way cool but I would suggest moving them further apart and bringing down the height or tilting them down.

Correction, I had the meter to record the low db, peak db is 112.3. I measured this L/C/R. Trimming my HF back on the mixer helped some.
