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.

@plaw - same here.

2 x Rythmik (E15HP2), with Wilson Audio speakers.
Those 2 Rythmik’s are about the same price as a single REL S/812.
Just way too many things not to like about REL subs.
Only 63 pages of comments on the AVSForum REL forum since 2008.
For example, SVS (1700+), Rythmik (2400+), PSA (3200+ pages).
Have never read a REL subwoofer recommendation on AVSForum yet (with the exception from within the REL forum itself). Outside that forum, nothing, or very rare.
Rel has solid marketing and has defined themselves as a room sub bass systems and talk about "tuning your Rel" - again marketing. I’ve owned a couple and they are good but so is Rythmik and I’m sure many others. JL looks really nice too.
I'm on a budget and am awaiting arrival of a pair of RogerSound Labs Speedwoofers. I don't like the fact they are ported, but am going to give them a try as they feature transmission line design [which matches what I have with my Atlantic Technology AT-1s]. Since RogerSound pays shipping both ways, they are the first to which I will give a try. I'm replacing a very dated Mirage dual opposed 8" sub which is far too boomy for my taste. All for music. 
Best sub is no sub, There's nothing below 160hz, hardly a  few cello notes and kettle drums, 
You guys are fooling youself.
