First Subwoofer.

[castlesteve]

I am going to build my first subwoofer using this woofer http://www.partsexpress.com/pe/pshow...Number=295-185
I am thinking of using the Apex Jr amp and will be using this for music and movies but mainly music. I would also like to keep the enclosure reasonably sized. Should i go sealed or vented? What are the advantages either way. I`m not looking for very high volumes, just good solid bass to fill in below my fostex 167s.

Hi Steve,

You might want to up the amp a bit. Even if you don't want it loud it will be better for the sound overall.

Edit: In simple terms:
Closed box= tighter sounding bass
Vented= More bass

I would use maybe a Rythmik Audio A250 Basic amplifier with 250W...

What is reasonably sized for you?

Your Fostex go down to which frequency?

[castlesteve]

I can afford the P.E 240 watt plate amp if that will work? My fostex mains are rolling off below 60hz and i can also stuff the vents if needs be. I`m leaning towards a sealed configuration to try to get tighter bass.

I was thinking perhaps anything up to a an 16 by 16 by 16 cube which should yeild a little over 2 cu ft.

Ok, so you got around 1.5 cu.ft internal to work with.

The Rythmik Audio A250 Basic is a 250W plate amplifier for 119$, if you can afford it, it's better than the PartsExpress one.

You should go sealed with a 16x16x16 box with this driver. Going ported that small is hard to do, also a ported enclosure that small doesn't give much gain over a sealed enclosure.
