LATEST ADDITIONS

Remember integrated amps? I do — my first two real audio systems were assembled around examples of the one-component, preamp/poweramp combination form.

So does Pioneer. The firm’s new Elite A-20 is an unabashed throwback: two channels, no radio, a few analog inputs (no digital), a few knobs. 

Everybody loves small speakers, and why not? Smaller is — often — easier to afford, easier to schlep home, easier to place, and easier to live with. Smaller also has certain acoustical advantages in achieving smooth response and in yielding the broad, even spread of sound that favors good imaging and an open, believable tone color.

But how small is too small? Some say there’s no limit, and at least one manufacturer (Bose) has had success with subwoofer/satellite designs whose sats are smaller than a pepper mill, let alone a breadbox. But as the front satellites of a speaker system become smaller, their ability to reproduce bass low enough to bridge effectively with the practical upper limits of a single subwoofer, at around 150 Hz (and ideally lower), becomes questionable.

Klipsch thinks it has found the sweet spot with its HD Theater 600 system

Between increasing your system’s audio channel count to 9.1 or 11.1 and upgrading to a bigger, brighter, or even higher-resolution 4K video display, there’s no shortage of ways to take your home theater to the next level. And while such improvements can certainly add excitement, the basic home theater experience still pretty much remains the same.

The thing that most home theaters can’t do is put you into the action, literally letting you feel what is happening onscreen. The sliding of gravel under the tires. The rock and sway of a boat. The thud-thud-thud of a jet being riddled with gunfire. Providing that experience is the role that D-Box fills.
