2 x Behringer B315D Eurolive 550W 15" 2Way PA Powered Active Speaker System

The general consensus among pros is to avoid Behringer products altogether.

If you’re looking for an affordable PA setup I would have a look at Mackie or EV’s ZLX series.

LOL … thanks … no pressure, right?

@OP: First question: WHY do you want your own gear at this point? 100-150 is way bigger than the average house/pool/birthday party (typically 30-50 people), which is, imho, a good place to have a highly portable PA that you can just throw in the back of your car. 100-150 is serious people and should be paid gig. Paid gig means people need to pay for PA too.

Until such a moment that you can safely say you’ll earn back your gear from rental fees (either plain rental or as part of your DJ fee) in 14-16 months (fees about 3-4% of new value = 25-33 rentals in that time frame = a lot), it just doesn’t make good business sense to buy your own gear. Especially not if you don’t have a budget to get quality gear, which – with all kinds of respect for Behringer – it still isn’t.

You will end up having to ask a customer to pay for gear that is sub-par to what the professional rental places rent out.
There is a reason that companies that rent out gear to people that PAY to listen to it, just about never use Behringer. And not just Behringer to be fair, but also the likes of American Audio, DAP and plenty of other low-end brands. While a good step above the no-name, too good to be true “super full power high range can do anything disco PA” speakers and amps offered on Amazon and OK if you want your own party PA for home/bedroom use and the occasional house party with friends, frankly they are just not up to par for serious on the road PA work. My opinion of course, I know there are those that have different views.

Don’t forget in PA the golden rule is still “You get what you pay for”. Right after “trust your ears”.

The reason I spent so much time at this point, is that, unless you have a really good other motive, it makes no sense to buy a PA early on. There are plenty of other (and imho WAY more important) items you can spend your money on in the early days of your DJ-ing career. Getting a nice mobile DJ booth (about 200 bucks) will do more for your image and professional appearance than having a set of Eurolives sitting next to the hotel function room table with obligatory cream colored skirt or rickety bar table that you set up in lieu of not having something your own.

First option to present to you is RENT! It pays to get friendly with a good rental company in your neighborhood. They will supply you with well-maintained, high-end, PA that you couldn’t afford yourself, often bringing/picking it up. You can negotiate a fee (usually between 15-25% of the rental fee) so you will make money bringing gear to a party WITHOUT INVESTING! And, if you get to know the guys and they get to know you, they might run into a gig where they need someone to DJ and come to you.

You can get the exact size of gear you need. 75 or 150 could be two totally different setups already, depending on the venue, the occassion, the musical genre, etx. If you rent, your gear can be 100% fitting every time.

Rental companies often will have different brands they use. So you get to try out several things and find out what YOU like best, so when the time comes to actually buy your own, you will have a much better knowledge and experience to make the right choice.

When it comes to “sizing” a room, the easy, rule of thumb calculation is 5W-10W per person depending on the event (10W for anything really dance party, you can get away with 5W for some weddings and corporate events). Double that when you go outdoors.
So, 100-150 people means at the very very least 500W RMS (probably what you’ll get from the 315s. Behringer states 550W, but conveniently leaves out the RMS bit, which usually means its not RMS but music power which is about half) for indoor, no headbanging. 1500W indoor for a serious party is no crazy number. In this case you’d probably get a big part of that from a sub (single 18″ at 800W RMS for example with two 350W top ends 12″ or so). Take the whole thing outside and it gets way worse.

Remember, more people absorb more low end frequency so your low end input needs to go up exponentially to keep the umph up to the desired level.

Hope that helps underwrite what I said about renting.

Other than that, use the search option as there has been lots written on the selection of PA in these forums.

FYI: My 2×12″, 1x 18″ Mackie HD-series setup cost me about 2800 euro after discount. They can be had a bit cheaper now they are an older model, but not a whole lot. Any other comparable configuration from other high(er)-end manufacturers in the same quality bracket will almost certainly set you back in the 2500-3000 dollar/euro range. Leave out the sub and you should still at the very least be looking at 1500 for a pair of speakers (excluding cables and stands = another 150-1200 easy).

I can, with 200% confidence, go into a room, setup my PA and dare to compare to anything the rentals throw at me. Why? Because it’s pro-level gear and looks/sounds accordingly.
