Default can you spice up a cheap sub ?

i am wondering if changing the driver on these
will improve the response
Nady PSW15 600W 15" Subwoofer | Musician's Friend
i know that at that price the wood and the driver must be crappy
but right now i cant afford high end cabinets
i was looking at some
EAW: SB150z
but the cost like 1200 each...

or something of these guys
http://www.community.chester.pa.us/f...22218d669e7aab

but the cost is prohibitive for me

is there some plans to build something similar with a 15" or a 12"
i need a simple sub that you can carry easily and since i carry it on my car
an 18" cab is out of the question
i was looking at the behringer one but they only make 18" 's
i need a 15

Now , what is better a single 15 or a dual 12, sorry for the newbie questions
but i am new to speaker cabs
and i want to maybe build a simple cab for myself
or get a nady and spice it up a bit

Thanks
Max.

Do you already have the sub? Here is my design in process with a driver that would work well in that box:

Ultra compact ported 15" Dayton Ref HO

You can do MUCH better from scratch for a little more money, say $150-200.

Exotic high end cabinets are nothing more than thicker plywood. Subs are easy, cabinets cheap. Cheap subs have cheap drivers and cheap amps to go along with their cheap box. You can DIY a really, really good sub for under $500. Not sure spending any money improving a really cheap sub is as good as setting that money aside to save up and build a good one.

Depending on the cone material, there is room to play. If it is untreated paper, you can dope the cone to damp breakup modes to make it cleaner, then remeasure the T/S parameters and re-size the box and tuning. You may get a few Hz out of it at the cost of a larger box and a tad less efficiency. You also may make a mess. DIY always has that risk

My all time best sub is a Peerless XXLS 12 inch in a 60L box, sealed. In room with a solid floor it gives just the right bottom end for music. No eq. What they do is lower distortion than about anything else.

A pair of them and a used pro sound crossover and you are in business to laugh at some really expensive stuff.

where you can get them and what boxes you can put them in
or what plans to build your own
if it is a 12" i think the box will be smaller than on a 15" and better for me
as i can load it in the car easier, maybe a pair of those
but take in account that those will be used for PA sound and not in a home theater installation

Since you have already bought the sub, try it as is and see how it works. Then try bracing it internally and otherwise enhancing the cabinet. Then consider replacing the woofer.
