Lights, Corner, Action!
One reason is aesthetics. Yes, it's obligatory to mention the tired, old "spousal acceptance factor", but the fact is that lots of people - women and men - don't like the look of a big honker of a subwoofer plopped down in the middle of the living room. (No one ever comes to visit and says, "Oh, I love the way you've added that big ugly box to your room. It makes the place look so mah-valous, dah-ling!") So the 10 CSB's cabinet is shaped very much like a triangle - the actual shape is something I'm sure I learned about in Geometry class but have since sadly forgotten - so it will slip discretely into any 90-degree corner of a room.
The other reason for the out-of-the-ordinary design is acoustics. (Wouldn't you know it?) Placing a subwoofer in a corner - technically known as "corner loading" - increases the bass response and sound pressure level generated by the subwoofer. Atlantic Technology's 10 CSB happily takes advantage of this well-known acoustic phenomenon (it's like cheating, only you don't get in trouble for it); and, since placement in a corner is a given, the company incorporates specific corner-mounted equalization that further improves the subwoofer's response and output. Atlantic Technology points out that a conventional box-type subwoofer can't be tailored specifically for use in corners because the eventual owner might use it in a variety of other room locations in which corner-mounted equalization would make the subwoofer sound less than optimal. ("Sounds like poo-poo" is the technical term for such a situation.)
The 10 CSB includes a 10-inch long-throw composite cone driver in a sealed enclosure. The built-in 180-watt amplifier uses a high-current design that's matched and equalized to the driver. The package also features a phase inversion switch, an adjustable (40 Hz - 140 Hz) 18 dB/octave crossover, plus low- and high-level inputs.
Atlantic Technology says the 10 CSB is available now. The suggested retail price is $899.
Which corner you put it in is up to you.
