Lightweight sub for PA?

Is there such a thing?  I mean really light... not something that's between 60 - 90 lbs... my back can't take the heavy lifting any more (yeah... I know... it's me that's the lightweight here).

Thanks.

The Yamaha Ines are quite light but probably a bit heavy still. Check out Inspired Audio. You'll pay for them but they're about as lightweight as I can remember lifting. Superb performance too.

The Yamaha DXS12 weighs in around 33Kg. It's heavy, but manageable single handed. Packs a punch too.
