Summary:
This is the absolute finest sub on the market. As one reviewer noted, it is like bottled lightning on bass tracks.
It is the most musical sub on that market and allows you to accurately differentiate the various instruments and their bass notes instead of one big bass mess. It can reproduce a 16Hz note at an astonishing 106dB!!!! It is without doubt the best of both worlds for both movies and music.

The rel subs are very music as well, but do not put out nearly the pressure/impact level that I like for movies.
Great subs and any enthuasist would love em.

The velodyne sub is raw, clean bass power. Awesome on movies and a good sub for music, but it doesn't compete with how seemless an Aerial can "blend" in with your front speakers for 2-channel.

All 3 subs are 5 star subs, but this one is clearly the finest made.

Strengths:
frequency extension, musicality, raw power

Weaknesses:
None, it is perfect

Similar Products Used:
Velodyne HGS-15, Rel Stadium, Rel Storm III, and many other subs

Summary:
great sub just got it hooked up and the bass is pretty fast well it's relly fast.
Just finished watching Event Horizen and the bass was loud deep clean and hit you like a ton of bricks.
I cant belive the sound on this unit

Strengths:
Speed, stong output from 18 to 40hz, loud verry musical , one of the best hometheater subs out there.

Weaknesses:
price other then that none

Similar Products Used:
SVS, Velodyne, Hsu, M&K

Price Paid:  $4000.00 from Audio Advice

Summary:
This sub beats everything out there hands down. I use it on a pair of 10Ts and love it. I am also using a Velodyne HGS 18 for LFE and an HGS 10 for my rear channel (Lecxicon MC-1 Preamp and Mark Levinson amplification). It does not get any better than this. It's also highly tuneable with a command center built into the back of the unit.

The sub plays loud, deep, accurate, fast, etc. Like bottled lightning, it's phenomonal.

5 star overall. I do wish it was cheaper but since this performace is not available anywhere else, it is still a bargain.

Strengths:
Depth, fullness, speed, slam, musicality, fidelity, you name it!

Weaknesses:
High cost.
