I would like Ian to comment on this one.
Why did all the specs just change recently?
New analysis methods? New testing procedure?

I've noticed that the subs are now rated for a lower frequency response than before. The EP350 'looks' more favourable now since it was previously rated at a low of 30hz and is now 25hz.
This isn't a change for marketing strategy is it?
