Spendor A2 vs A4

Hi all,

Looking for insight into which of these will match best to my room.  Dimensions are approx. 18 length x 12 width x 7 height - so around 1500 cubic feet.  Typical material is folk, indie, and jazz, with a good splash of orchestral mixed in.  I use a Hegel H90 amp (60 watts class AB with unusually high damping factor). 
I heard and loved the A4s in a medium-size room at a dealer - I actually preferred them to the A7 in that space - but haven’t heard the A2.  In that listening session my only gripe with the A4 was slightly uncontrolled/boomy bass.  That concern is what leads me to ask whether the A2 might be a better bet in my space. 
I’d greatly appreciate opinions from people who have heard or owned both speakers.  Please no suggestions for other brands - it’s down to these two. 
Many thanks!
