Our take on the PSB Alpha LR1

by Kristen Schaub
PSB

Why choose bookshelf speakers?

Bookshelf speakers may be small in size, but they can deliver surprisingly big sound. Some ultra-compact models even fit on a desktop. Most are right at home in tight spaces like shelves, so they're usually good choices for your home theater's rear channels. For the best performance, try placing bookshelf speakers on solid speaker stands to help the sound really "open up." If you want full bass impact, add a powered subwoofer and enjoy punchy sound that's as deeply satisfying as that of floor-standing speakers.

Compact speakers deliver deceptively big sound

The Alpha LR1s are the smallest speakers in PSB's lineup, yet they still manage to deliver dependably crisp, clear PSB sound. These versatile speakers can be used as both front and rear satellite speakers, making them an excellent choice when you're looking to create a high-end, budget-friendly five- or seven-speaker satellite system. Designed to be wall-mounted or placed on an entertainment stand, they're the perfect solution for rooms with various seating arrangements and odd sizing.

Excellence by design

PSB's engineers began by designing each Alpha speaker from scratch to ensure that they'll deliver the same level of performance typically found on speakers twice their price. The Alpha LR1s use a 3/4" aluminum dome tweeter to deliver crisp, sparkling highs. The 3-1/2" woofer is made of metalized polypropylene, making it strong but lightweight. You'll hear excellent midrange detail and distinct bass without a trace of the listening fatigue that can happen with lesser speakers.

Build a complete Alpha system

Create a complete, budget-friendly Alpha home theater system using five to seven LR1 speakers mounted around your room. Or use the LR1s in the back of your room, and add a pair of Alpha T1 floor-standing speakers or the B1 bookshelf speakers to the front of your room. And don't forget to pick up a PSB powered subwoofer (or two) for room-thumping bass.

0.75" Tweeter: Each Alpha Series LR1 is equipped with a 0.75" aluminum dome, ferrofluid-cooled tweeter.

Waveguide: The LR1's tweeters utilize an acoustical waveguide to deliver, more even high frequency response, no matter what part of the room you're in.

Crossover Network: The tweeters and woofers are crossed over at 3,000 Hz.

Magnetically Shielded: The LR1 is magnetically shielded for safe placement adjacent to your television.

Enclosure Design

Wood Grain Vinyl Cabinet: The PSB Alpha Series LR1 features a black wood grain vinyl cabinet that matches almost any decor.

5-Way Binding Posts: The 5-way binding posts will accept bare wire (up to 12-gauge), pin connectors, spade connectors, banana plugs, and dual banana plugs.

Wall Mounting: Each PSB Alpha Series LR1speaker features a single keyhole slot and a 1/4"-20 threaded insert to wall-mount the speaker. In addition, non-skid rubber bumpers are attached in the corners of each speaker, so not to mar wall surfaces when the speakers are mounted.

Alpha LR1

Written By DAR, York, PA on Monday, August 25, 2014
Crutchfield Customer Review (What's this?)
 
perfect speaker for my application in terms of size, sound reproduction and price. needed a small satellite type speaker for a wall mount location in a 5.1 music/movie setup. the room is not large and already had speaker mounts on the walls, but only enough room for a small bookshelf. fills out the surround field perfectly, look great, sound great and the Crutchfield special pricing was a bonus. also took some time to break them in on another system and they sound pretty good with a small 8 inch sub to help fill in the lower end. highly recommended for these type of applications.
Pros:
small size, super clean highs, good looks, great for small satellite installations and small bookshelf and sub setups
Cons:
none
