great music subwoofer on a budget

[ifonly]

I just turned 15 and i have been saving for a subwoofer and i thought it would be fun to bulid it myself. We have all the tools i could need. My mains are DCM timeframe 600s great speakers and a Yamaha RXV 995 as my receiver they are a great team but now I need more bottom end. It is about a 0-300 dollor budget for amp and sub the less money the better. It will only be used for music but it will have to preform well from high speed double kick drums to deep heavey rap bass. I would like to see the amp atleast 240 rms and the sub 12 inchs and up or a 10 with a passive radiator. Size dosnt matter to much as long as its not taking up the whole room the room is also about 500 square feet.
With this info i hope you can help me.

Here's your amplifier (109$) :

Want to go sealed, ported or passive radiator?

Since you said less money is better, this sub might interest you (75$):

This is a nice website for basic understanding of subwoofers.

Check the systems at the left in the menu.

Check out t-linespeakers.org. They've got some nifty designs for simple transmission-line woofers that don't cost much to make. Add a 50$ plate amp, and you're done.

I would take the amp simon suggested and go with a Dayton RS 12" HF or HO. It'll cost you about 250 bucks. Its what I have in my living room (the HF in 3 cubes, but the HO could fit in a much smaller box) and its great. Especially for the money. The sub can be found on www.partsexpress.com just do a search for dayton.

What about the DAYTON QT385-4 15" is that a good sub for music as well and the 250W SUBWOOFER AMPLIFIER w/REMOTE CONTROL from parts express because it is on sale for 109.

you need only a small amp.

The DAYTON QT385-4 15" QUATRO is a very good driver for the price but it will need a large box, but that's no problems for you.

I prefer the Rythmik plate amplifier over the partsexpress one because the Rythmik is an improved partsexpress amplifier for the same price or less.

I think the Rythmik + Quatro will be a nice combo.

It does well in somewhat small sealed ones too. I built one with that driver and the rythmik audio amp mentioned. Sealed in a 18" cube and it turned out great. Now it isn't going to reach down to 14-18Hz with allot of athority but it handled the LOTR (ext.cut DTS) trilogy with out any problem. It was also very, very good with music. 18" cube is roughly 73L and according to unibox it has a "Q" around .663
