Easy Folded Horn Design?
« on: June 05, 2007, 11:33:24 am »

Hi

I hope I'm not asking a question that's been asked a thousand times already. I've had a look and couldn't see anything so here goes...

Does anyone know of a design plan for a folded horn sub that is relatively easy to build? In other words, one with as few pieces and complicated angles as possible. I realise that none are actually simple but I'm looking for one that's the least complicated (but still actually worth building!).

The application for these subs is to replace the existing subs in a local nightclub. Its a small room and is currently using 2x Bose 502B cabs for bass and nothing else. They're not being used with any other Bose equipment at the moment. The sound system's just a random pile of speakers. The reason for building these subs is to make a more attractive looking sound system that sounds at least a little better.

Me and the manager decided to go down this route after going to a club that was using a Funktion One Dance Stack. We want to build something big and intrusive and folded horn subs are where we are going to start. Then if we like what we've made we're going to do a few horn type mid/tops and paint them in some nice silver paint Smile

Thanks in advance to anyone who has any ideas for us. Just to recap we're building these to beat Bose 502B's. They don't have to be the best subs in the world.

Try speakerplans.com great site and you can build up to 4 cab's before you need to pay for the plans... Personally i'd look at the X1 which is actually a bandpass box but appears to look like a folded W shaped cab... Have a look around the site its great  Smile  Although personally i wouldn't build a folder horn for home theater if done properly you wont be disappointed  Smile

Thanks Sam. I've been on that site already actually and I think some of their horns probably are the simplest I've seen. I agree with what you said that the X1 doesn't look too bad. It's the one pictured on the website isn't it? I'm not sure it really does what I want though.

I was planning on making a horn because of the high SPL (and appearance). The really low frequency extension isn't all that important to me. The Bose 502B's that are currently in use claim to have a frequency range of 55-155hz although I don't know how many +/-dB that is.

I've found a good website but I don't understand a word of it!

Check out billfitzmarice.com  The Tubas and Titans are very good subs and pretty simple to build if you have any woodworking chops at all.

They certainly look pretty amazing. I quite fancy making a few Titan 48's. Have you ever made or heard any of these Bill Fitz Maurice speakers? Do you really think they can be as good as they seem?

I know the response isn't as flat but some of them are compared to EAW speakers and look pretty good next to them.

Yes I have built many of them.  They work exactly as advertised.  The main problem is found with air leaks.  YOU MUST KEEP THE CHAMBER AND HORN AIRTIGHT. This is critical for any horn sub.  The people who have problems generally have a leak, when they fix the leak, the response is always the same. WOW.

For recorded music I would suggest the Tuba series; for live music the Titan series.

I'm pleased with my Tuba 30 slims.  I had them built right before the release of the Titans or I would've chosen T48's.  More building this summer.

What about the Punisher horn from speakerplans.com  Smile  How big is the dance floor in your club? Are you thinking of 15's or 18's? How do you intend to power your subs? Also how many do you intend to build? Are you attempting clear bass or do you want that 'thump' that hits you hard? Is this install or do you want to be able to move them? 4 punishers stacked and driven with 1000 watts should rock the house... or build 8 and really kill some grey matter  Very Happy

I'd either do Titan48's, Tubas or Punishers.  Titan48 and Tubas will be cheaper to build and lighter.  Haven't built the Punisher or Tuba but I do like the Titan48, it was worth building and does much better once you have 2 or more and can couple them.  Either of the BFM options are hard to beat for the cost to build.  Tubas go a little lower than Titans and may be a better nightclub choice...

If its for dj use wich it sounds like it is I'd recomend the Tuba 36's over the Titan 48's, they go lower.

I just had 6 of them built and after testing them with only 20 watts (testing for leaks etc) I couldn't believe how loud they were. Clean as all hell too. And that was WITH some very minor air leaks which are being fixed as I type this. These things are insane. Go for the Tuba 36's, I gaurantee they will not disappoint.

Thanks for all of your replies. I've been away for a couple of days and not had chance to check up here. With your recommendations I'm going to make a couple of Tuba 36's and see how that sounds.
