Good ole budget build sub

punkrokr1701 · 4th July 2008, 11:25 PM

ok guys I haven't had much chance to check in the forums for a long time now and now that i got my comp built I'm looking at attempting a budget build $300 complete sub woofer. I'm looking at a very simple set up, Basically cut the cabinet, plug and play sort of set up right now. Birch is my choice of cabinet material, 1/2" is in consideration but i think i might as well do 3/4" for $10 more. As expensive as everything is nowadays a $300 build of decent quality is becoming more of a challenge. Anyways, I'm thinking of pairing up a Dayton driver rated at 300 watts rms @ 4 ohm with this bash amp. Very simple like i said. As far as enclosure goes a ported 4 ft^3 @ 28 Hz box seems best, as this will be 3/4 music use and the rest computer gaming and some movies. Anyways I would appreciate some input on this and if anyone knows of anything better off let me know.

BTW I have had bassbox pro for so long i done forgot the name of the freeware enclosure response modeling software i used to spend hours on, i know it's a very common program but i can't put my finger on it's name even after some goggling. Can someone help me out? lol

The BASH seems cool, unless you're thinking of using the plate amp's high-pass section for your satelites. From the picture of the unit, it seems to have no high pass, though I don't have one and can't say for sure.

I missed this on my first several glances at the unit, so I thought I'd point it out...

Depends if you can handle a bigger box or not. 18 inch, 15mm Xmax, 94.2db sensitivity, $145 shipped to your door.

I'd take the sensitivity rating with a grain of salt.

hmmm bigger is always better but damn that price just keeps going up and up, i remember when it was $58 plus $18 shipping

My personal fav, it's actually around 99.2 dB with my SPL meter.

Hmm, without knowing all the details of your measurement it's meaningless in the scheme of things, especially since its published specs calc a ~93.2 dB/W/m half space reference efficiency, though at 2 ohms its sensitivity is ~99.22 dB/2.83 V/m (4 W).

Like any other low Qts, Xmax driver though, it takes a huge box to go low with any authority at low distortion.

it's 99.2 in a 5 cubic foot sealed box.
