Looking for a Commercial dual 18 subwoofer for Sound Renfocement

lawbadman · 27th September 2010, 08:30 PM

I am setting up a sound system for a church and I need a suggestion for dual 18 inch subwoofer that would be up to the task. I will be using it for bass guitar and kick drum.

I notice that it takes a lot of power to reproduce kick drums at a decent volume. I have heard many systems where once everyone else in the band starts playing the kick drum is drowned out. I dont want this to happen.

The building is a rectangle about 50 x 100 feet with a triangular ceiling (starting at about 10 feet) reaching approximately 30-40 feet high
I will be using a EP4000 to drive it. I have a budget of up to $2000 maybe less.

Any suggestions????

I am thinking about these:
JBL SRX728S JBL :: Product

EAW LA128Z EAW LA128Z

ASB6128V JBL :: Product

I suggest you get a sound level meter.... go to some venues and measure what level you think you want music reproduced @ so you have a ball park target... Then think about what distance you want this to be reproduced @.

With a target then you can think about how many boxes you need to get there.

Have you considered DIY... because you can build 6 2x18 for 2Gs... Run with the same amount of power... the 6 boxes will be 6 to 12 dB louder and far cleaner than a single 2x18 near your budget.

Hi,

I don't have this sub but have read some of the raves about it and feel comfortable that the sub should do what's expected. This company is owned by "Craigsub". The website is still being worked so you'll have to call to order.

Take a look at Jim Bell's big tapped horn:

You can build one for less than $250 and it will be louder and sound as good or better than the JBL or EAW

I'm pretty sure a lot of the punch of a kick drum comes from harmonics, so don't neglect the mid-bass. Hook up a spectrum analyzer (use the PC or laptop) and look at what comes out of the drums and bass. You may not need a true subwoofer at all.

ince these subs don't have to be movable, maybe a pair of horn-loaded subs is the way to go. Have a look at the designs at Speakerplans.
