bass application for tailgating.

My company is going to be doing charity events for the Atlanta Falcons this season. We already have stage monitors. We're looking to build something simple and cheap for loud and clean bass. Also... We're not looking for insane world record bass. Just enough to sou d good with the monitors. I've done a little research on bass horns. Anybody suggest a design that is cost effective? Amp suggestions would be awesome to. Thank you

Lo9ok for a used Yorkville LS801P. In Canada they can be had for around $600 used Takes 2 people to move do to weight but will be easier to move and setup compared to a bass horn. They don't play deep but have a ton of output.

What size crowd are you looking at and whats the rest of your equipment?

We are looking to build the sub. Like a group fun project. We have strong men that can move a cab around. Crowd is unpredictable. 50-500.

As soon as I read "bass horns" and "stage monitors", I think of Bill Fitzmaurice.

Read through his various plans for sale to see what matches up what you're looking for. And have fun!

Man... Those builds look tough! For novice wood workers... Seems like a tough task at hand lol.

As far as designs go... The tuba 30 looks solid

so, you want simple, cheap, clear, and loud bass? you forgot small. you have to be flexible in one of those. I know that sounds harsh, but we'd all like that. Alot of subwoofer manufacturers would be out of business if such a thing existed. What's most important? Or better yet, what's the least important? What are you willing to sacrifice? $ ? time? performance? ease of construction?
DIY is about doing the work ourselves to get the performance without shelling out the $$ for someone else to get their hands dirty doing the 'tough' stuff. Besides, you're in Atlanta, and I'm sure someone in your group knows someone who has some woodworking skills, and has the tools. It may cost you pizza and some beer. Throw in the 'charity' bit, and hope they're a Falcons fan.

It's for 'wall hung dude', and no, I don't need any help to 'hook-up'.... sheesh ... dirty minds around these parts....

Well of course you can do it. Lots of things seem hard if you've never done it... until you do it... and you learn.
2 steps forward, 1 step back. Determination will see you to the goal. Of course it doesn't seem easy. Nothing worth achieving ever is.
Remember, the obstacles are only visible when you take your eyes off the goal.
C'mon... what's the charity? Is it worth some effort? Of course it is or you wouldn't be doing it. Well, you can do this too. You're not the first to be ... intimidated (lousy word,but I can't think of a better one right now) by this, and you wont be the last, but if a schmuck like me can do it....
Just go for it. We never grow until we're pushed outside the boundaries we're comfortable with. This is me pushing. You can do it. And we'll help. But, we won't accept excuses... only results. We can accept mistakes along the way... Hell, we expect them, but there won't be anything that isn't solveable. The cumulative IQ here is tremendous.

The nice thing about BFM is that step by step instructions are given, so you don't need to be an expert woodworker to complete the build. And they have a forum that'll provide support.

Consider the T39 instead if it's for live music (don't need to go as low as the T30).

The BFM subs are front loaded horns (which should be cleaner sounding than the other designs). They may be slightly more complex to build than tapped horns.

A tapped horn design to look at is the SS15.

FWIW approximately 80% of our cabs are built by first timers. That includes the builders of this system:

Many of these now former novices can give you advice on my forum as to what will best fit your needs.

How about a lilwrecker?

Are you limited to just one box?

The infinity 1260 has a lot of bang for buck. 4 of those ported at 25hz would be nice for the money ($250).

That's too low a tuning for most music. Think pro audio subs (40+ Hz) rather than home theater (20+ Hz). Otherwise the cabinet is larger than necessary.

The response is rather smooth and the cabinet is 3 cubes per driver. Plus you can repurpose it. 40hz is too high. 28hz might be a nice compromise, but when you model it you are not giving up too much with that versus all the extension at 40hz.

True about repurposing.

I just realized you were talking about two different things: the lilwrecker and the ported Infinity. I thought you were talking about the Infinity in the lilwrecker. I apologize for my confusion.

Just looked up the lilwrecker:

Quote:
Dimensions are 70" long, 28 1/2" deep, and 25 3/8" high, so each cabinet is 29.3 cubic feet external. This is not exactly a small cabinet. Each cabinet takes 4 4X8 sheets of ply, radman12 used Arauco. Bracing is not drawn in the plans, but is required. A single, windowed brace in the center of the panels is sufficient. The build was done with PL premium and 1 5/8" drywall screws.
It's not small. It's tuned to 17 Hz. It's a great design but for home theater.

O-horn is really what he wants. http://www.data-bass.com/data?page=system&id=81
With a high pass filter on it under tune. But his budget is a tad shy. For $500 it's not possible.

And yes I was talking about ported infinity (in multiples) at 28hz. nice response. Easy build. Good output. Could make two boxes, or one. I'd do at least 4 drivers to get good output, especially since each subwoofer only costs $60.

For $500 he could probably do 8 of them, if his budget can stretch for a little more wood and glue. 8 of them ported at 28hz would sound great for music. Put on a highpass filter and you could pound on them too.

For tailgating? Its twice the size you need for as low as music goes, and its not exactly portable. All things considered T39 is ideal.

You are not going to be able to build or buy anything for $500 that will cover 500 people.

There are some decent, free, plans here:

http://hornplans.free.fr/cubo15.html

Scoops are small and easy to make but limited on bandwidth.

To cover 500 people your gonna have a van or box truck full of gear.......

$275.

Port that pig at 36hz in a reasonable 8-9cubic foot box it should lay down the bass over 120db+ no problems.

although again, you can buy 4 of the infinity 1260's for less and port those at 28hz and get the same output with better extension.

Does that include finish input jacks and some type of xover?

Anyways this is all pointless until we know what tops he is using and the rest of his equipment.
