Default PA sound system

In the next couple of months I will be throwing a once a month electronic music event featuring lots of bass heavy music and I need to buy/construct a PA system that will shake the walls of this little 65-75 person bar ...

BUT I'm a virgin to PA setups ... And to DIY speaker assembly... So I was wondering if you kind folks could offer me some advice-lessons, ect ...

Initially I was hoping to construct something retarded and overkill but I dont think I need to break glass in this small place , not yet anyways ... I think maybe 35-40hz response would be good for now ...

And for what I see myself using this soundsystem for in the next 2 years is - this small bar , maybe another slightly larger bar and some indoor and outdoor house parties that I could use a handcart to move my equipment into ... If I could rock this small to semi-small spots i'd be happy ... Of course , as long as the whole place was rattling

...

Again - the bar I'm starting this event up at is small ...

It is the shape of a rectangle with an area in the back corner that you walk up 3 or 4 steps and they then place an adapter over the stairs to create a makeshift stage out of it to maximize space ...



My MAIN concern is DOING THE MUSIC JUSTICE. Giving the songs their proper range of sound .... And since i'm a bass fiend [dnb - dubstep - breakz - hiphop] the low end is my nirvana ...

range of bass is more important than overall loudness , considering this place is so small... But I do want it to be a wild dance party so I need enough volume and bass to rock the **** out of this little bar.


I'm thinking I wont spend more than 2k unless the ratio of performance and value was dramatically increased proportional to the amount of cash increased.

I do want new equipment ...

and I also had heard the price jump from 15" woofers to 18" woofers isn't even worth it because you can just double the amount of 15's you buy and you'll equal if not exceed the bass of the same money spent on 18's ... Sound right?? For instance 4x15 for the cost of 2x18 or something similar ...


The only audio setups i've done really were hooking up some event monitors to my soundcard and an amp and a couple Home Theatre systems for my TV and one for my Computer so again i'm a virgin to this ... But i am looking to pop my cherry :teeth:

someone please help me pop my cherry

hahaha!

thanks guys

I would use this driver for the mids:

And this driver for the bass:

I have discussed these drivers on Speakerplans.

Not realy.

You can buy 4 x 15" for the price of 2 x 18" but those would be 4 budget drivers against 2 quality drivers.

Difference in pricing between 15" and 18" of similar quality would more often be 10 -35%.

Well you left out some things we need to know.
Do you already own wood working tools?
If the answer to the question is NO then I would suggest purchasing a TH Mini sub from Danley Sound Labs, 2/4 Peavey SP10's or 12's. Behringer DCX2496 Ultradrive. 2 used Crown XLS 602 amplifiers. (1@600w stereo @4 ohms for mid/highs other bridge for 1200w mono for sub) A gator amp rack and a Furman power conditioner. That should be right around 2.2 K
A PA that puts out over 130 DB from 50Hz-21KHz.
-10DB at 41 Hz. In a size that can fit into a hatch back!

If you do and want to build your own then how will you transport said system?

Wood working tools could be easily had and I'm glad you asked the question because I gives me a sense that this is do-able , even for a beginner ... I hope LOL.

How about the CS30 or the TH112 mixed with a couple of other loud speakers to cover the range? I'm guessing the CS30 may not kick out that 33hz response far enough out into the crowd?

Also I do have a furman , although its only used for my home studio equipment , computer, monitor screens, keyboards and 300w QSC amp...

And for transportation - I'll be using my girlfriends pickup for the time being ... If that falls through LOL , i'll be borrowing a truck or SUV from a friend or family member

Although I do love the idea of having something fit in a hatchback! Unfortunately i'm a tall lanky bastard standing at 6'3" so as much as I love VW's and Subaru's and old school honda civics - I dont fit in them very well haha ...

thanks again

How do you feel about the UltraCURVE pro :

http://www.audiomidi.com/DEQ2496-Ult...o--P4245.aspx#

as opposed to the UltraDRIVE - i'm guessing the Curve is more eq centered ??

In another thread someone suggested the T36 horn saying:
"Its a single 15" horn that takes about 300 watts to be almost as loud as a JBL dual 18". big cabinets though, but WELL worth the money, high dollar to db ratio here."

Any Thoughts?

I'm new to all this so i'm trying to run comparisons to wrap my head around things.

No, you need a crossover to only send bass to the bassspeakers and mid-hi to the tops.

However, i would advice to stay away from behringer on such an important function as the crossover and get a DBX 223 , RANE AC22 or some other similar and more reliable crossovers instead.
The ultracurcve could still be used as system eq since it then would be possible to bypass it when it breaks.
You also have other all-in-one alternatives like DBX PX which can do both eq , crossover and a lot of other useful stuff.

The DCX2496 is one of Behringer's better pieces. Being all digital, there are no cheap analog pots or switches to tear up (the usual failure mode). The DRPA is not as good, so if the DR 260 is too rich for your blood the 2496 is the way to go.
