Surround Sound Speaker Systems

My ensemble arrived in two shipments and the delivery man was not amused. All speakers arrived well packaged and in good shape. After unboxing the whole group, I began to wonder how I was going to get them all upstairs into my media room. The towers were big and fairly hefty, but actually only take up less than a square foot of floor space. The F12s have a clean line with a nice cherry veneer.
They can be bi-amped and the binding posts are well spaced out on the back of each speaker. The F12s are a 3-way design with a 1 inch tweeter, 5 3/8 inch midrange and two 8 inch woofers. The C12, which was a lot heavier than I expected, is also a 3-way design with the same dome tweeter as the F12, a 4 inch mid and two 6 Â½ inch woofers. Spikes are included to replace the rubber feet if you want to set them on carpet.
The back of the C12 has an adjustable rod to tilt the speaker down (if mounted above your TV) so the tweeter is at ear level. An optional speaker stand can be purchased for about $200 if you want to place the C12 on the floor in front of your TV or projection screen. Of note, it does not have a boundary compensation switch so if you are planning on placing it inside an entertainment cabinet, be forewarned. The S12s are solidly built with two 1 inch tweeters and two 5 inch midranges.
They sport a switch that lets you toggle from bi/di/mono. Bi: both sides are in phase, Di: both sides are out of phase of each other, and mono: one speaker group is off (thus giving you a very pinpointed sound source). The B120s were sent a wireless signal via a transmitter.
With the optional TX1 wireless transmitter connected to the audio system, the B120 can be placed anywhere in the room (without cables) within reach of an AC outlet.
One or two B120 subwoofers can be operated with a single TX1 transmitter. These 2 subs took up a fair amount of my floor space, but the advantages of having two subs will be discussed later on in this review. The 12 inch woofers were made from OCC (organic ceramic composite) for rigidity and light weight.
All of the Concerta tweeters had the Constant Acoustic Impedance technology applied to them to help with a more even dispersal of high frequency sound and better blending with the mid range drivers.. All speakers have a cast metal faceplate and internal bracing for rigidity and to fight off unwanted cabinet resonance. The boxes are made of MDF and the speakers felt solid and heavy.
