JBL EON712 vs EON715
Quick answer
Take the EON715 at $559.99 if you have no subwoofer budget and a band to carry, because the 15 inch woofer buys real low end for about eleven dollars more. Take the EON712 at $549.00 for speech-led services and anywhere weight and size matter.
JBL Professional EON712 Powered PA Speaker, 12 inch, 1300 Watt
$549.00 Specs and sizingA 12 inch woofer in a smaller, lighter cabinet with the same 1,300 watt amplifier and the same 100 by 60 pattern as its larger sibling.
Best for: Wide rooms of moderate depth, and anywhere the front rows are currently being missed

JBL Professional EON715 Powered PA Speaker, 15 inch, 1300 Watt
$559.99 Specs and sizingThe identical electronics behind a 15 inch woofer, which buys usable low frequency weight without adding a separate subwoofer.
Best for: Contemporary worship in a mid-size room that has no budget line for subwoofers yet
Check price on AmazonThese two are the same loudspeaker with a different woofer, and at $549.00 against $559.99 the price is close enough that the decision is purely about what the box has to do. Same 1,300 watt amplifier, same 100 by 60 degree pattern, same DSP and app control.
So do not treat the 15 as an upgrade. It is a different tool: more low frequency extension, a bigger and heavier cabinet, and slightly less tidy midrange directivity where the larger cone starts to beam. For a church, the deciding question is whether a subwoofer is ever going to be bought. Run your service style through the subwoofer sizing calculator and the answer usually appears.

Which one suits which service
Match the woofer to the content. This is the whole decision and it takes about a minute.
A 15 inch main is the right choice only where a church has a band and no subwoofer budget, which is the single situation the extra cone area is bought for.
| Service style | Subwoofer planned? | Better choice | Why |
|---|---|---|---|
| Traditional, organ and choir | No | EON712 | Nothing below 60 Hz to reproduce |
| Blended, piano and light band | No | EON715 | Carries bass guitar without a sub |
| Contemporary band | No | EON715 | The only way to get low end at all |
| Contemporary band | Yes | EON712 | High-pass the mains, let the sub work |
| Portable weekly setup | Either | EON712 | Smaller and lighter to carry |
| Under-balcony or side fill | Either | EON712 | Fills need clarity, not weight |
If a subwoofer is in the plan, always choose the 12. A high-passed 12 with a subwoofer beats a full-range 15 on every measure that matters in a room.
Choose the EON712 if a subwoofer exists or will
Once a subwoofer is carrying everything below about 100 Hz, the main cabinet no longer needs cone area, and a 12 inch driver is the better midrange device. High-passing the mains also frees their amplifiers from the hardest work they do, so the whole system runs cleaner at the same level. This is why nearly every well-designed church system uses 12 inch mains with subwoofers rather than 15 inch mains alone.
The 12 is also the more practical box for a portable team. Smaller, lighter and easier to get onto a stand safely, which matters when volunteers set up weekly. And it is the better choice for any fill position, where intelligibility matters and low end does not. See under-balcony delay speakers.
What you give up: on its own, with no subwoofer, a 12 will sound thin under a bass guitar and a kick drum. Be honest about whether the sub is actually coming.
Choose the EON715 if the sub is never going to be bought
Plenty of churches will never approve a subwoofer line, and for them the 15 inch main is the pragmatic answer. It gets bass guitar and kick drum into the room with weight rather than as a click, and for about eleven dollars more per box that is an obvious trade.
It is also the better single-box solution for a fellowship hall, an outdoor service or a youth room where one speaker per side is the entire system. In an outdoor service there is no room to reinforce the low end, so cone area is the only thing that helps.
The honest cost is physical. A 15 inch cabinet is bigger, heavier and more awkward on a stand, and at head height near a congregation that is a real handling consideration. Use stands rated well above the cabinet weight and lock the height properly.

Frequently asked questions
Is a 15 inch speaker always louder than a 12?
Not at the same amplifier power, which is exactly the case here. Both cabinets have the same 1,300 watt amplifier, so maximum output is similar. What the larger cone buys is low frequency extension and sensitivity at the bottom end, not more overall level. The 15 is deeper, not louder.
Will a 15 inch main muddy speech?
It can, in a reverberant room, because low frequency energy is what a hard-surfaced sanctuary holds onto longest. If speech clarity is the main problem in your building, a 12 with a high-pass filter set around 100 Hz usually sounds clearer than a 15 run full range. Treat the room as well.
Can I mix a 712 and a 715 in one system?
Not as a matched pair of mains, because the two sides would have different low frequency response and the image would pull to one side. It is fine to use 715s as mains and 712s as fills, since the fills are equalised and delayed separately and are not expected to match the mains exactly.
Which is better for livestream audio?
Neither, because the stream should not be taking its audio from the room at all. A livestream mix comes from a dedicated bus on the console through an audio interface. If your stream audio depends on which loudspeaker is in the room, that is the problem worth fixing first.
How high should these be mounted?
High enough that the cabinet clears standing heads and aims down into the seating, typically with the horn around seven to eight feet on a stand. Too low and the front rows get everything while the back gets nothing. Aiming matters more than height, which our placement guide works through with real angles.
