This is a pair of cheap Chinese PA cabs branded as 'Class D' (yes, I know) which I bought maybe 10 years ago.
These are NOT disguised Mackies or whatever, they are NOT top-quality and they will NOT transform your sound.
But they'll do a job for you and they will NOT cost you very much.
The range of scuff marks is impressive and you can see that these cabs have been relic'd by a true Master of the trade, but they're fully functional for all that.
They can be used as a perfectly reasonable pair of speakers for vocals in a band with backline, or as the tops for a PA with a separate sub-woofer, or (probably best) as wedge monitors or side-fills.
I've put £50 as a vague guide. Make me an offer.
They can be collected from HA1 3RG or at any Junkyard Dogs gig - http://www.junkyarddogslondon.co.uk/index.html
