How powerful is a Wavac MD-300B

Hi Pani, I have a pair of Wavelength Cardinal XS @ 10 watts (& Wavelength 45s) in a 12' by 15' room (somewhat open on one side) My speakers are Beauhorn Virtuoso w/Lowther DX4 (106, with MORE than enough volume) You really need to borrow or have someone bring over quality 300Bs to try or at least buy used.

I just found a review by Jack Roberts at Dagogo of the EC-300B, where he begins by stating that he also had previously lived with the MD-300B for quite some time prior. I found it strange that he did not give a comparison between the two.
I then found his previous review of the MD-300B. He basically says about the same for the both.
At three times of a price difference... there should be a big difference...

Tannoy offers different designs for particular applications. I very much appreciate their offerings, the Westminster Royal SE.. WOW! Placed properly they will shine!
