Extending the Gradients' curve
As a Quad ESL enthusiast, I know how difficult it is to blend subwoofers with very good, very fast loudspeakers. Consequently, I was impressed with the new A225-M powered subwoofer from the Swiss company PSI, on demonstration at the Simplifi Audio room. Used with the Gradient Helsinki loudspeaker, of which I also have some experience, a pair of PSI subs ($4500 each) provided lots of deep, impactful bass with no apparent change in the Gradients' timbral character: very impressive. The subwoofer was housed within one of the the same IKEA units as Simplifi's Tim Ryan was using for component stands, to show that high-quality sound can still be domestically acceptable.
