Without question I totally agree with Owenlee.
I own the Spatial Audio hologram-3. I have the Turbo Xover upgrade with a twist
since it is a very minimal 2 HD order Xover I paid extra for his new prototype Mundorfs silver Gold Oil cap for the ,highs and Mundorfs resistor
and reference Titanium Nitrite Reference 1.75 inch compression driver in the center of the Emminance 15 inch driver ,then a matching 15 inch to low midrange and Low bass to 30 HZ. Please remember anything under 29 HZ is roughly just
vibrations ,lowest concert grand Piano 28hz Maxed out this 4 ohm speaker is
93 do efficient at 1 watt for under $3k these open baffle speakers just open up and flow effortlessly even in a small 10x 12 room ,and no boxiness or energy
being sucked out . Check them out . A no Brainer Best Buy !!
