Summary:
this sub bloody rocks'' those clowns who think this sub is muddy should buy a decent cable

Strengths:
awesome home theatre, great 2 channel stereo

Weaknesses:
wife,neighbors

Similar Products Used:
nothing compares for value

Summary:
This 18" sub moves a lot of air but does it with Trian like force - it is a little slow but commanding, would suggest it for movies but not music. Overall it has been great, got it used and love it. It gets four for being just a little to like mud with music and five for value for shaking the house and the guys next door windows during DVD's.

Strengths:
Good for movies

Weaknesses:
Can be muddy with music - slow throw - big 18"

Summary:
This is the first 18 inch sub I've ever owned.
I removed the grill type cloth that surrounds it
so that I could see that massive woofer at work,
I think it looks better with it off! I have a huge living
room and this power house really does an incredible
job. I have it hooked to the sub output of my pre/pro.
The LFE channel on DVD's is no match for this beast.
The bass is clean, powerful, and LOW, LOW! I've had it
for 2 years and have no plans to replace it. This
monster will handle anything I throw at it now and
in the future. 5/5

Strengths:
Solidly built. Nice "piano black finish" top.

Weaknesses:
No removeable grill, no "auto" on/off switch.

Summary:
I replaced the M&K with the Def Tech 1800. The 1800 is hooked to the sub out for LFE. I have the PSB 3i wired into the fronts to relieve the front speakers of the frequencies below 50 hz. The Def Tech moves plenty of air and works very well for the LFE channel. If you can get your wife to okay such a massive unit, get one. Don't let not having an auto on bother you. It doesn't draw very much current, I leave it on. Sitting there powered up will not hurt anything. I paid $1180 plus sales tax from a local dealer who ordered it in from Def Tech after he called Def Tech for a competitive price.

Strengths:
Low Bass

Weaknesses:
no auto on and very heavy, bulky

Similar Products Used:
PSB 3i, MK MX200, Velodyne 12" sub

Summary:
At that price you would expect a great product. This sub does not even have a "auto on" feature. It draws so much current that you just can't plug it in to the "switched" outlet on your receiver. I have owned this sub since '95 and 3 months after I purchaced it the amplifier went haywire, and a mechanical rattle from the speaker itself. I hope their quality has improved since then. If they have improved the quality, I would reccomend it even though it is not the tightest bass around. (Sorry 3 Stars on my experience of this speaker)
