Ok, I get this marketing thing from Adire Audio praising the advantages of XBL^2 technology and how great it is. It goes on to list all the advantages compared to other technologies including underhung motors which I have with my SD3-10 and indeed it is a very low distortion design. I’m not so sure there is an advantage by comparison to my AudioFrog GB12 which I think is an overhung design with nice copper shorting rings to keep inductance in check.
So there must be shortcomings too because with speaker design there is always a trade off like efficiency for example vs bandwidth. I hear that XBL motors aren’t very efficient and consume lots of power to get the same SPL compared to designs like the AF. So this is an advanced discussion about subwoofer motor design that I hope someone can intelligently discuss and support and I thought this forum needs some good topics/discussion too.
Another thing I don’t get is they say it’s cheaper to manufacture an XBL motor because of the shorter top plate and coil but why isn’t that reflected in the price or is it? I’m guessing the AFGB series costs much more to make if anything just because of the added copper shorting rings.
Thoughts?
