We make our own drivers????

'Made in England from Birch Ply' spec sheet below clearly states cabs are MDF....

Not rebated, or finished very well looking at the photos. 

Looks like photos are two different boxes, some cut hand holds and some metal bar handles. 

Maybe...BB281 stands for Billy Bullshit..218..!!

And that design g£s out to Ying.Tong@Cheapspeakermaker.cn, who d£s what he has quoted for, at the price agreed.

I wondered when a remnant from Carlsbro might pop up again. When Carlsbro was made in UK, had some OK stuff, if you liked MI gear, but still have some PA heads that still work. Noisey, but they were out of the box.

However, when they started bringing it in from China.....As politely as possible - the quality was not up to their previous levels.

Funnily enough, they then went bust.

The only good thing to come out of Carlsbro in the last 15 years, was Mal Ward, their former Rep, who is now with Pr£l UK. Nice chap.

LOL, did you notice this:
First it says:
Power RMS (W)2000w


Then it says:
LF (Power/Sensitivity)1400w/125dB


Then it says:
Sensitivity (1w/1m)(dB)122dB
Max SPL (dB)129dB



RMS 2000 or 1400W?
Sensivity unlikely 125dB or 122dB?

Let's calculate:
1 W = 122dB
2W = 125dB
3W = 128dB

And then we're almost hitting the low max spl of 129dB at 3 WATTS LOL :-)

Yes, the figures in that ad are definitely all over the place and totally unbelievable, but I think that you`ve forgotten to factor in a 10*log(power) in your calculation!  Embarrassed
