Sound system question...

I put this in another thread about the gig bench, and no one answered it. It must have gotten lost in the post...

Anyhow, I put new Eons on the gig bench to complement my QSC powered 18 sub. I noticed that I had to crank up my sub (QSC powered 18) a little more with the new Eons. I have the low pass filter turned on on the sub, with the output to the right and left inputs of the powered two ways on top.

I have always run my mixer (sub control knob) at 8 O clock with the old speakers (cheapos). But with the Eons, I had to turn it up to 11 O clock to get the same level out. Anyone know why? I would have thought the better quality tops (the Eons) would allow me to turn down the mixer...

Ty -

Forgive me for not remembering, but were the original tops powered? Have you tried turning off the low pass filter on the sub? Is there a db cut setting on the back of your mixer?

I'm grabbing at straws here...........

Just some guesstimating and presumption-ating on my part...

A teensy bit more sensitivity rating on mid tops will cause a noticeable difference in output. The Eons are not bad at all for SPL when used as mid tops.

Rather than boost your sub gain, try cutting some gain to the Eons and see if that warms things out. Once you get it to your liking, leave it alone. :)

Sparkie's right. When EQing or tweaking your sub feed via crossover, ensure that you are not feeding it with frequencies lower than it can reproduce. Keep your bass tight with punch at first. You may ease the frequency down a little at a time and see where the mix works best.

I was thinking along the same lines, last night.

But wanted to think about it for a while.

I too was leaning towards maybe the Eons had better sensitivity than the "cheapo's" (which usually are not very efficient)

...that signal out was simply the signal out. The feed comes from my mixer to the sub. Then out of the filter to the tops (all speakers are powered).

The amount of bass coming from the sub was much greater with the old speakers. I still get amazing sound with the Eons, I just have to turn up the "bass" dial now to get the same level. Thanks guys!

You can get new speakers on CraigsList, that will outperform the current ones, but it will cost you :sqlaugh: :sqwink:

Ty, I'm glad to hear.

Just be sure that your goosed sub gain doesn't redline at higher levels. This is why I suggested cutting gain to the tops first. But as long as it works out, good deal. :)

Precision Power, the Eons offer a decent response curve and sensitivity rating for no more than they cost. You can pay a lot more for a little more SPL in a similar cabinet design. I give 'em props for vocal tone.

As with any full range speaker system, people tend to go wrong when they try to get it to do more than it was designed to do. People see a 15" driver and think they can thump the house with it. Well, yeah. The 15 can thump... but don't forget about the rest of your sound. :)

Interesting thread.....I was testing my set-up at home last night, the set-up I will be using tomorrow.....2 JBL EON's 15" (Tops), and 1 JRX 118SP Powered Sub woofer. I was getting a real muddy bass from the sub.....
Well, I slept on it, and today, to clear it up I dropped the gain on the Sub??? It worked......

What I'm thinking is should I have increased the gain on the EON's, I currently run them at 12:00??

Thanks, Jim. I'm happy to hear. With the system you're running, you'll be fine. :)

The 12:00 setting or neutral attenuation is a starting point. Should you have to, you may increase or decrease a bit to achieve your preferred tone and balance. I have always advocated cutting slightly rather than boosting. If you boost, the temptation to boost other levels or frequency responses is hard to resist. :)

Fred,
My thought's on this, was in no way a bash on the Eon's.
I've noticed through research of my own, that "cheap" or lower priced
products tend to not have good sensitivity numbers.

So let's say Ty's old top's were 95db, and the Eon's are 100db.(Just making number's up here) The Eon's would be abit louder with the same wattage as the old top's.....Correct???

This was a good meaning post, No dis-respect to any gear mentioned.

Absolutely. A +5 dB sensitivity rating would make one heck of a difference in SPL. :)

This topic tends to get some folks riled up but you can't change the laws of physics. What you can do is tune your system for good tone.

If I could do it with RS home stereo cabinets, it can surely be done with professional mobile gear. :)

I don't have a sub to worry about.... yet... but I do have one piece of gear in my rack that keeps me honest and doesn't allow me to send more than my full range speakers can handle... no it's not a crossover... it's my Behringer Ultra-Curve DEQ 2496.... basically I set it to cut frequencies below 55hz as my speakers are only designed to go down to 60hz.... i have tried cutting below 55hz but once the volume goes up my speakers would fart instead of thump.

This along with pre-eq'n the room with an RTA mic has helped my sound out immencly over without it. Just my 2 cents worth.
