3 way powered bass tower speaker that is more refined and tunable than other powered speakers. This solves 2 common problems. Placement effects bass significantly and this allows you to tune it. This includes the ability to use them in different sized rooms effectively. The other advantage is to play with more authority and ease because your amp doesn't have to work as hard delivering amperage to make a woofer move air.
Sensible Sound Says this.
Whether mostly conventional in design or not, when I fired up the Ergo RC-As in my large peaked- ceiling family room and listened to a wide range of classical and rock material, I immediately remarked about two pleasing things. The first was a noticeably easy, unstrained quality to the sound at all levels, including when driven hard; I even noticed this when measuring outdoors with pink noise. This impression is almost surely due to the built-in hefty power amp driving and filtering the double woofers. The second quality was an unexpected airiness to the sound, and again I noticed this outside as well with pink noise, as I moved my measurement mike around the tower eight feet or so away from it.
I do not normally hear much of either of these qualities with speakers sent for review, and certainly did not when listening critically to the last two high- end designs I covered for T$S, from Eggleston and Buggtussel, which were themselves worthy accomplishments and not all that dissimilar to the Ergo RC-A.
