Friends,
Need your advice on 2 X 18" plans for 18 Sound 18LW2400 & Fane 18"Colossus Prime XS.
Reflex or Horn Loaded, please advice. We are a sound rental company doing Live Band Concerts & EDM Festivals in Stadium & Arenas with a crowd of 5000 and above on most occasions.

The Eighteen Sound you are considering can work in either a horn or bass reflex. The Fane you are considering is aimed for reflex cabinets not, horns. For the amount of people you are stating you are catering for, it would be best to focus on one type of speaker and buy quantity. Your top cabinets will dictate whether a slew of horns or a slew of reflex cabinets is the best choice pending on how low of a frequency your top cabinets can produce.

 

Best Regards,

Dear Elliot,
Thank You for your advice.
The Line Array tops we are using start from 60hz
Between the 2 components what will you advice - 18 Sound or Fane.
Yes we will be using only one brand of components only and won't be mixing the two at all.
All our concerts are Bass heavy especially when we are doing the EDM Festivals.
Regards.

If your tops can reach down to 60 Hz, you are better off with Reflex cabinets as you will have no issues achieving one octave lower. The majority of bass horns on the market take a nose dive under 50 Hz. So it would make logical sense to choose the driver that was designed for a reflex box based on your choices of the two speakers you are considering. 

 

Best Regards,

For edm I would go for horns. Especially on this scale.
Be carefull with line array tops they may have -few db there.
The best give concrete tunes you want to sound best and tops or at least lf drivers in tops.

how long have you been in the business? If you really do events on that scale, it's a little bit weird that you would need to come to this forum to ask for ideas. Don't you have any personal contacts in the business? Competent employees? Why not hire a competent consultant, if you don't know yourself what to do?

If you were a real, viable business, you wouldn't waste your time here  Ouch

Bob4,
My competent employees had come up with a horn design and we made 2 numbers to test them but the components just didn't sound good in the cabinets. We have a existing dual 18" G Sub design which we are using but since the past 6 months we have been doing these concerts and we always fall short on subs. A friend suggested to join this forum to ask advice from people in the industry. I am 60 years old and just continuing the business which my friend and i had started. He was the technical man but he's no more :( that's why i am here seeking advice.
Regards.

Roger just out of curiosity and which will help in advising you accordingly, if you do a gig for 5000 people at present , what are you using to cover that audience?

Is that a trick question?

How about 18lw2400 in front loaded horns? Should reach easly 35hz without excursion problems in few pcs stacks.
Will also produce some extra kick for those la.

I know enough to know I know nothing.

But how/why have you chosen drivers without knowing what you even need?

The question about what you're already using seems utterly legitimate. Seen enough threads to know unless you stump up some answers to questions the conjecture will meander and you'll end up either none the wiser or with answers that dont fit your needs.

Rish,
The tops are 2 x 12" Low-Mid + 1 x 2"HF (MT122 Design from speaker plan.com)

JonB67,
I haven't chosen any drivers, this is what we have currently in our G Subs

Friends,
Thank You we have decided to go ahead with reflex subs and increase the G Subs quantity with the Fane & try the super scooper design for 18 Sound.
Appreciate the advice received from all.
Regards.

Neither G Sub nor Superscoop designs are licensed for commercial use. Just so you're aware of that.

Francis - I am a little lost to why you would think that was a trick question. Write this down "One never really knows where he is going until he knows where he coming from". I wanted to know what he has currently and either expand from there or sell that and build a system from scratch.

Roger - Building a sound for 5000 peeps would need much more than you have now. Bass reflex cabs are great to cover the low end section but you would need quite a few to cope properly. Mt121 also good for the audience you want to cover with the proper drivers but then again you need more.
The most important thing here is that make sure you set proper crossover points and time align the system once built. Too many times I have seen systems with a whole lot of cabs not time aligned and sounding crap. Building cabs is one thing, knowing how to use them is another.

On page one you say that you're using line array tops that go down to 60hz...On page two your saying you use MT122?

I still think he is Roger Drego fishing for free ideas on the next ripoff.

I wonder if this is the same guy who was emailing me a few weeks ago. At first he asked for Othorn plans like any other DIYer, which I give out all the time, so I thought nothing of it. The follow up emails sent up red flags immediately. I was asked if I had other plans, full range cabinet designs, or any other links to prints or plans of pro cabs I knew of. At that point it was mentioned he worked for an audio company and started sending info on an amplifier line. I quit responding once I realized I was being dug for information by a company that would try to copy others work and sell it later on. I wish I would've realized earlier.
 
I was specifically asked for line array plans. Sounds like the same person to me...

Not a BPH, at all. It's a proper bandpass box, very, very far from a reflex…

Roger Drego recently did cold play in India, and there were supposedly 80,000 people at the venue.

It's a high order bandpass so has a very large group delay.
