High quality equalizers

I’m taking delivery tomorrow of a new Manley Massive Passive. This may be synergistic with the Purify 6.5" mid/woofers and matching Purify passive radiators in my modified Merlin VSMs. The Purify drivers deliver clean, albeit rolled off, LF into the 20hz region.  Reportedly they have ample headroom to play with.  I’ll find out how they tolerate an equalization boost of up to 20db!

A few hours into the Manley piece has me convinced.  Rich & concise and dead quiet, as a fine tubed unit must be for the studio.
