The new eons are rated at 300 watts.  Technically, Is that enough for the average karaoke job?.

My Yamahas are rated 500 watts.

You talking the EON original powered, the next generation powered G2 series or the unpowered 1500?  I haven't heard of any new series out other than these.

I read the specs on a G2.

The G2 is not a new series, it's been available for approx 4-5 years now.  It's a 400 watt speaker, 300 watts to the woofer & 100 watts to the tweeter - 400 watts total.  More than most systems today offer.  400 watts per side is 800 watts total.

JBL EON 15P 2 - Way 15 In Powered Speaker

This 2-way 15 in. PA cabinet is internally biamp powered. The biamp design provides dedicated power amps for the low frequency 15 in. driver and the 15 in. compression driver. The lows are driven by 125 watts and the highs by 50 watts. By separating the power amps the cabinet is more efficient and sound quality is more precise. This cabinet features a high-output, neodymium 15 in. driver with a 1.75 in. voice coil. This contributes to its light weight and the portability that everyone loves about the EON line. >More

JBL EON15G2 Powered Speaker with EQ

The JBL EON15 G2 delivers 300 watts of power to a 15 in. neodymium Differential Drive¬ LF driver. The driver boasts a dual neodymium magnet and dual voice coil motor that efficiently delivers high output from a lightweight woofer. Meanwhile, the HF amplifier delivers 100 watts of power to a 1.75 in. titanium diaphragm compression driver with Ferro-fluid cooling




Copied this from a site.

Exactly, 300 watts to the 15" woofer and 100 watts to the 1.75 in. titanium horn = 400 watt speaker

When MGM started doing talkies in Hollywood RCA had the contract.. A new upstart company by the name of Altec Lansing took over the contracts with a better system. Over the years they became the industry standard in all PA sound systems wordwide. At some point they renamed to JBL..

They still remain the industry standard Web Site. Their tech support is probably the best I have ever known in 40 years of designing all types of commercial or home systems. I even had a Sunday call back from tech support regarding rf interference from the WWV time broadcast transmitters near Fort Collins Co.. On the web site above one can find downloads for schematics to any product they produce.. Most parts are generic and readily available JBL will sell any replacement part at a reasonable cost..

There are a few of the first eons including the P1 and 15 pak but the common wattage was 130 on the 15” and 80 on the diaphragm….The G2 series upped the wattage to 300 on the 15” and 100 on the diaphragm…..   They make excellent Pas with a mic input in fact we have rented out a single eon to a car dealership for a pa on their car lot.  Several blocks away it sounds like the announcer is standing 3 feet from you.

One of the big advantages besides dependability is they can be chained (the g2 series has a buffer amp and basic mixer to hook up additional speakers)   in the same way that a 70 volt speaker is so that sound can be distributed in any venue as required. .Anybody that has worked with sound systems in any fashion should be familiar with JBL quality and reputation..

Exactly, that's what I said!  The G2 series produces 300 watts to the woofer, 100 watts to the highs = 400 watt speaker!

It IS considered a 400 watt speaker.  300 to low, 100 to high!

This is a bi-amped speaker?

A related question.

How is the power distributed to a passive speaker with a 15" and a horn.   How much power goes where?     What decides this much goes here and this much goes there.    Or does the speaker have the same handling capacity as the horn?

Yes it is considered a bi-amped speaker with an active crossover design inside.

I second that emotion.....

In a very basic explanation, the crossover built into the cabinet is what determines what frequency & power gets to what driver.  Basically the signal gets divided through a series of chokes, resistors & capacitors then filtered on down to the corresponding drivers which can actually reduce the effective power the amp is trying to push.  How much is filtered is completely dependant on the design of the crossover & components.  Which is the biggest reason why active crossover designs are much more desireable because there is no frequency or power loss to the drivers, the result is a much clearer sound & adjustable to fit different needs.

Yup...In an eon the signal is split into a LF (low frequency processor) and a HF (high frequency proc ) then routed to to respective LF HF amps

BTW the heat sinks for the amps are located above the 2 holes above the 15" bass Cooling is provided by the bass displacing air thru these holes I have run eons in the hot sun all aft at triple degree temps no problem...

They are RATED at 500 watts, but do they get 500 watts is the question.  You are running 1 amp with 2 subs & 2 mains off the same amp.  The sub doesn't have any crossover so it's getting & trying to reproduce as much of the spectrum as it can which results in muddy sound.  The mains are also trying to reproduce those same frequencies which results in muddy sound.  The amp is getting tired because it's trying to push all the frequencies to all the speakers.

Bottom line the JBL's would be PLENTY for any average Karoake venue. There are many out there that use them. Also MANY bands use them.

So with an active crossover you can set the wattage going to the horn and speaker.   I know you can set frequency, I'm asking about the wattage.   So that you don't blow the horn by giving it too much.

I find that with a pair of G2's you still need a decent sub to sound good.

I wouls never DJ or KJ with out a sub. I wouls suggest a JBL MPro 18" active as they are being cleared out as the line has been discontinued to match these speakers.

You can't set the wattage to anything.  The amp determines how many watts CAN be delivered.  The crossover design will determine how much power is filtered - but with a passive design, there will always be a power loss, often times ALOT of power loss.  With an active design, if you amps are properly rated to the driver, there is little to no power loss.
You can blow any speaker with any amount of power, but if the amp power matches the program power of the speaker, chances are less likely.  With that being said, you can also blow a speaker sending it frequencies it isn't designed to handle.  3T brought up a good point about your sub.

First of all you must define "average Karaoke job". If you mean a normal karaoke show in relation to provided a good sound... absolutely . I have use JBL Eon G2's for over 2 years now and have had nothing but compliments on the sound. If your talking the size of the venues again...absolutely. I have done all sizes of rooms and currently run 4 to 5 shows a week with no problems. One venue is pretty large but with the advice of the knowledgeable Kj's in this forum I just added another G2 and I was able to handle it. The one thing I will say liquiddye is correct you need to make sure you add a sub or 2 at some point to give it that quality sound but its a great speaker.
