Passive 18" Subwoofer with Built-In Crossover

Latest User Reviews
i'm impressed
i've used lots of live systems, this ECO is amazing and competes with rival double the price.
sounds good, deep lows, nice punch and has built in crossover.
at this price i guess it's hard to beat.
Cheap and powerful speakers
I use the speaker at private parties. Sound is very loud and powerful. Build quality is also very good and speakers are nice looking. Cons are that speaker rear panel connector are only 2 pole and I can't use single cable to feed both subwoofer and sattelite speaker from amplifier rack. I will replace the connectors with 4 pole by myself. I will also add wheels to subwoofer rear to make transportation easier.
Basically with some modifications you will get perfect subwoofer with low price.
Amazing sub
Sounds great and is compatible with any mixing console
18" Subwoofers
These are heavy and could do with casters. However they are OK to handle with two people grabbing a handle each.
They're big and solid and the threaded socket for poles is good quality.
No one knocks your top speakers over when they're mounted via a pole on top of these.
They have transformed my 8 piece band's sound from excellent to unbeatable.
I also chose these because they're passive but have a built in crossover and a link out to the satellite speakers. This allows me to use one stereo power amp instead of two and a speaker management system etc..
I'm very happy with them to be fair.
