Thinking of building a sub for SUB20hz bass.........HELP

post #1 of 10
Thread Starter 
Thinking about building a SUB that can complement my SVS PB-12NSD.

I need the bass in the 5-20hz range.......I want to be able to watch BLACKHAWK DOWN and FEEL the bass in IRENE!!!!!!

I would like to make it portable......actually I'll corner load it with my PB-12 for maximum headroom gain....

Options....opinions.....comments.....directions...I'll take it all!

There ain't any easy, cheap or portable option that I know of.

Getting deep-low bass REQUIRES plenty of displacement and enclosure size... no way around it.

Why not just make a subwoofer that can replace your NSD that can go farther down and play better than it does already?

have you considered bass shakers? not the solution you were looking for I am sure, but it's portable and straight forward to implement

Budget and room size are important to know. Without knowing that, there is one opinion I will offer... most solutions that would do better than your existing sub below 20hz would ALSO do as well as or better than your existing sub above 20hz. In other words, there's nothing to gain but some additional integration problems by keeping both subs in the chain. You'd be better off selling the SVS, and using the proceeds to increase your DIY budget, than trying to integrate the two of them into one solution.

Got inspired by the "Why bother?" thread eh?

Like the others said....either build a sub to replace your SVS entirely, or use some bass shakers/buttkickers.

Sounds like a IB would be exactly what your looking for minus the ability to move it. As mentioned it's going to take a good amount of displacement but certainly doable.

I know there's one IB setup with huge displacement that was sending visible waves across the carpet with Black Hawk down. Is that what your looking for?

Do the IB I will go to the depth you are craving.

I just installed mine and it is absolutely unbelievable. I have not tested the Irene clip yet but have done it with the Flight of the Phoenix plane crash scene. Truly unreal. No buttklickers needed in my room -- the chairs (and your body) shake on their own.

My manifold has (2) SoundSplinter 15's. I plan to add another dual driver manifold for stereo bass!



You might also talk with ebr. He built his with (4) 18"ers. His takes the cake on unreal!


And here is is Freq Response. The Red one is his IB and the blue is his SVS Ultra/2 sub. Look how low the IB goes and how the normal ported sub falls off.

I have 4 of the Soundsplinters as well and I will say the stuff below the 15-18hz mark is scary. Your not really hearing it but stuff in the room is moving funny, almost gives the impression the couch is moving and somewhat disorienting.

Hard to describe but once you experience it you will know what I mean.

My 4x15 Atlas'.... I will never go back to a regular box sub as long as I can do IB
