The response for REL regarding subwoofers

The response from REL regarding adding a REL Subwoofer for Cornerhorns.

"Unfortunately a speaker with that kind of sensitivity is going to be near impossible for any subwoofer to match with. The 2 volumes will never be able to match well. "

Is that true?  It doesn't sound true to me.  The SPL to power will be steeper than a less efficient speaker but it should jut be a matter of adjusting a powered subs gain curve to match that of the high efficiency speaker output or just using a more sensitive driver in the sub.

To bad I really wanted to buy a REL sub but I guess I'm not understanding how speakers work.

I think there is a limit to how much of a spread changing the gain on the subwoofer amp can manage. 
 

The average dynamic speaker is sitting between 87-95 DB efficiency. The Klipschorn is 105! 

At half a watt the KH is putting out 102DBs! The amount of gain needed for an amplifier to hit that output is very very very small. It gets worse as you get into more normal listening levels.

Think of how little gain would be needed to play those Khorns @ 85DB. 
 

The Rels, being probably more average in efficiency, would need a significantly higher amount of gain to match the output. 
 

Much higher than the gain difference on the subwoofer can accommodate.
