Building a cheap high powered sub.

[pikipupiba]

I am building a high powered subwoofer from the ground up and trying to do it as cheaply as possible. I intend to use this sub for DJ and all around party purposes, so it needs to be loud, compact, and still sound good.

I am using a PYLE PLCHW15 driver and 3/4 inch MDF.

The Loudspeaker Design Cookbook is my main source so far.

Using the book, I have decided the size of the box should be 4.57 cubic feet, but seeing as a lot of it is still over my head, thats all i really have. Any suggestions on shape, driver placement, etc.?

From the book I see one of the relevant parameters is something called the Qtc, is it something you 'pick' instead of measure?

If this is for real DJ purposes what you should be looking to build is a high power bass bin not a sub. That chest thumping that you hear and feel at clubs is mostly around 60 to 80Hz and most clubs roll off anything below 40Hz because it just muddies up things.

You should also look into Pro drivers such as the Eminence Kappa Pro, not cheap but they will stand up to constant high power use such as DJ / club work.

btw - that Pyle driver is meant for in vehicle use and uses the closed "cabin gain" of the vehicle for most of it's punch - a very bad choice for what you are trying to build......

Well crap haha. I would say the most important thing is cheap. It's not that I don't want to spend the money, I just don't physically have the money, so cheap is the front and foremost concern. I already have this driver, so any suggestions that don't involve spending more money?

Since Pyle doesn't publish any specs let alone the t/s parameters for that driver there is not much I can do to help. Put it in a car and it will probably sound OK, but try to design an enclosure for your use without the t/s parameters for that driver is just a crap shoot, sorry....

You could just try it in a 2 cu ft sealed box with medium amount of stuffing, won't be ideal but should be reasonable.

The amazon site gives...

Fs:21.2, Qms:5.0, Qes:0.90, Qts:0.75, Vas (Cu ft)5.204

Still, I'd take these with as much salt as the 3000w power rating...

Waste of money to even build a cabinet for this driver.

Hi pikipupiba,

If you already have the speaker on hand, you could measure the T/S parameters, and at least you would have a starting point. If you don't know how to do this try the google. If you haven't bought it yet, I'm with djk, and the salt mine.

Regards,

Yea, I do already have it, so there is no going back there. Now moving on to my other relevant question, do you pick of measure the Qtc?

[pikipupiba]

I meant to say pick OR measure

Here's what google turned up for T/S params:
