Best sub for music,


Not HT, repeat not the boomboomboom of HT  effects.  which does not offer the high fidelity of musical sub bass (20hz-40hz) 
I'd have to go with the seas W26E001. which has a magnesium/aluminum cone. 
What that raitio is, not sure, seems 50/50. 
None of us here like the sound of those old aluminum cones. But my guess is Seas had to incorporate some alumium inorder to gain the 20-30hz and also mabe keep costs down. 
This YT vid says **Aluminum cone** which is confusing YTers.
Its a  composite, and perhaps the best ture woofer on the market.
Been around for ages, still hard to beat for pure natural low mids. .
Magesium is the best material to keep unwanted resonances out in the  60-1k range, very low/hardly measurable distortion. 
The issue here  tops out at 1k, so its really a  sub. 
This woofer may be a  good candidate to pair with a  5 inch wide band.

Best sub is no sub, There's nothing below 160hz, hardly a  few cello notes and kettle drums, 
You guys are fooling youself.

OP,  You’re only fooling yourself by believing in “Best sub is no sub”. Carry on! 
when I went to buy my first sub, the rule of thumb was, “you only need one, bass isn’t directional”. That didn’t feel right to me.
At 80Hz the waveform is about 14 feet long. This means that in most rooms within a couple of iterations of the cycle of the bass note is reverberance- so its also omnidirectional. At lower frequencies the waveform is even longer. That’s the rhyme and reason.

Two subs works better simply because you reduce standing waves a bit with their use. 3 subs works better; 4 subs works excellent with quite diminishing returns above 4.

Low E on a string bass is 41Hz. You're fooling yourself if you think bandwidth that low or lower won't help with realism.

Ralph is a gentleman, with impeccable physics. Takes a Brit however to get right to the point.
