Max1636 Posted January 9, 2012 Report Share Posted January 9, 2012 I've been thinking SMD Subwoofers are just so powerful I don't understand why they aren't used in concerts? I mean concerts mostly use dual 18" woofers which are usually rated around 600 Watts RMS. But in a large setup they could be like 50 of them which is about 30, 000 Watts. With just 10 SMD Subs you get 35, 000. So with so much less equipment I thought It would make more sense. I thought the reason might be that more subs working with less power sounds better but I wanted to get another opinion. I also wanted to consider impedance. I'm not actually sure what the SMD's are at but I've heard 0.5 Ohms which could be difficult but do-able to connect to Power Amplifiers. I'm sure perhaps even a 4 Ohm model could be made though.

lifted_silverado Posted January 9, 2012 Report Share Posted January 9, 2012 Smd come in dual 1 and 2 ohm. They also use full range equipment. Having that many subs (at that weight) would really be overkill since many concerts dont even play in the range that the smds would really appreciate. They would spend 2x as much paying for components to balance the output of the smds imo Everythings in the attic or garage since the truck was sold last year. New build should be coming soon in a dodge cummins Link to comment Share on other sites More sharing options...

No but I was just wondering why concerts don't use something like the SMD subwoofer? What I'm getting so far is that they aren't entirely efficient.

Yes, and most concerts don't need to play 'low low' like we do, so using a sub designed to do that well would be kind of a waste. Plus they are super heavy and I don't believe that it's size would lend itself for use in something like a folded horn style enclosure ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...

Better options for that environment, especially options that don't include building everything.

412 CVX Posted January 9, 2012 Report Share Posted January 9, 2012 SMD's have a 4 inch coil iirc. means they can handle a lot of power, but take a lot of power to get loud. Just say no to Ground Pounder Customs. My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.

skittlesRgood Posted January 9, 2012 Report Share Posted January 9, 2012 completely different applications. the speakers they use are PA speakers and have a much larger bandwidth. then you have the efficiency part where another sub might be able to get twice as loud on the same amount of power. If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.
