Speaking from exerience as someone who has built a W bin, unless you are very confident of your woodowrking skills - dont bother. I ended up scrapping mine when it became apparent that my mitres were just not accurate enough - but hey we all gotta learn right?

I would highly recommend constructing one or two dual 15/18" loaded subs first, possibly in the G sub design featured on speakerplans (I believe). You can use other drivers and stills imulate with winISD and I believe you will be a lot happier with the result than if you build the w bin.

Once you have vented subs sorted, then Id move on to bigger and better things. I wish I did it that way.

I have a single LR36 Cerwin sub and it does not play low at all. Infact it just sits and takes up space in my system, however it seems like it would be good for DJ work with its built in wheels and tilt handle. It is rather efficient at midbass as well.

I regularly use 2 EV sb180 subs, and they're the quasi horn loaded/slot vented design. They definately play lower then the CV sub does. However with their "scooped woofer back design" they have a pronounced rise above 100 Hz. This adds extra kick which may or may not be desireable.

I'd rally like to try the servodrive basstech 7 one day though....

Any other horn loaded bass bin W Bin, Scoop, Half
folded, or Cerwin Vega's 36 Series, will only be able to
go down to 60 - and maybe 55 Hz using one box.

There is an exception to the W Bin that is 48 inches
deep, but, that's the same size as the Lab, Bassmaxx,
and, Servo Sub.


Bass horns are designed to be used in groups to
create one large horn.

If you don't have the space, the time, the money,
and, patience to build a horn loaded bass system
the right way, you are better of building one or two
Double 15's (Or 18's) enclosures.

That's basically the truth, and, nothing else but the
truth.

reply to darkm4n:

The driver you choose is not suitable for bass bins due to the low wattage for a pa speaker 350w max is 175 w rms,and not sensitive enough.
So I can imagine your on a low budget, So the Eminence Delta 15 400w rms,Kappa 15 450w rms,kappa 15lf 600w rms,kappa pro 15 500w rms all costing around under 100 quid.

Not any driver works in any box,and horn cabinets for pa need drivers of low QTS,high BL product[ high motor strength] and highish EBP[Efficentcy Bandwidth Product].

http://www.dancetech.com has many easy to build bass bin plans just look under da PA gear section-- and scroll down quite a way until u find da plans of:
W bin,15 inch scoop,15 inch/18 inch reflex bins.
All these plans on this site uses cheap-ish pa drivers such as the Eminence Kappa 15lf and Fane Classic 15300.

A scoop bass bin has the best mid bass 'thump in the chest' in my opinion.

You can buy a good speaker from Selenium.
WPU1505 or WPU1805 (450/900W) are a good driver at low cost .
Selenium distributor in Romania is SC Studio B Serv. SRL , www.difuzoare.ro , info@difuzoare.ro.

There’s an awful lot of good PA that can be done with a scoop and a horn. The best part about them is that they multiply out into bigger systems well.

Double scoops used to be all the rage. They often had a bevel cut into the back to hold a pair of casters. Grab the handles and tilt it back and even I could get them on and off the truck.
