Can someone tell me if I understand this correctly? I was looking at SVS PC12-NSD for $749 shipped. I thought I could probably build one cheaper and as good if not better.

So I like the look of a cylinder sub, it fits my space the best. A box is out of the question. I currently have a Force Field 3 which is tiny and my wife hates it.

So here’s where I need some clarification. My goal is for a cheap as possible – with a max budget of $749 to get a sub that will play pretty solid down to 16 Hz. And due to my (lack of) wood working skills and my space, it has to be a tube sub.

I’m looking at the SoundSplinter RL-P12 as the sub (I’m definitely open to suggestions on that choice). It says optimal volume for a 16.5 Hz Fb is 2.5 ft^3 for a vented enclosure. That’s it?

I can get a 16 inch diameter QuickCrete form at Lowes pretty cheap. So…

Vc= pi * r^2 * h

2.5 = pi * ((16/12)/2)^2 * h --> 2.5 = 1.3962 * h --> h = 1.79 ft or 21 7/16 inches tall?

That’s it? I must be doing something wrong here. My math tells me my sub will be 16 inches wide by less than 2 feet tall (roughly)

Thanks for any help.
