Pioneer Electronics SP-BS22-LR Andrew Jones Designed Bookshelf Loudspeakers, 80W Power Handling, 55Hz-20kHz Frequency, 6Ohms Impedance, Pair

The Pioneer Electronics SP-BS22-LR Andrew Jones Designed Bookshelf Pair Loudspeakers is designed for both professional and entertainment enthusiasts with the capability to deliver a full, clear and tight sound response for applications where space is limited. Built with a 4" (10.2 cm) structured surface woofer, 1" (2.5 cm) soft-dome tweeter and 80W of peak power, this speaker is designed for home theater, whole house audio systems and anywhere quality sound projection is required. The SP-BS22-LR speakers utilize a true curved cabinet design. So besides the aesthetics being considerably more pleasing, this stiffer design reduces standing sound waves inside the cabinet, resulting in high-performance and exceptional sound quality.

Thinking Out Of the Box
The SP-BS22-LR speakers utilize a true curved cabinet design. So besides the aesthetics being considerably more pleasing, this stiffer design reduces standing sound waves inside the cabinet, resulting in high-performance and exceptional sound quality. As you look at them, you'll also notice Pioneer's unique speaker grills. They're beautiful and elegant in their own right, but not for their own sake. They protect the speakers, but are also removable if you prefer to see the drivers themselves.

Crossover
The job of the cross over in a speaker is to break the audio signal into low, high and sometimes mid-range frequencies. It's an important job and it uses circuitry like inductors and capacitors to accomplish it. Much of the competition uses an extremely simple, low-cost cross over made up of a single capacitor and inductor. The Pioneer SP-BS22-LR utilizes a sophisticated 6 component high quality cross over. The reasoning is simple: they do it because it's one more way of insuring high quality sound that makes its presence known.

Woofer
There are many challenges designing and manufacturing a woofer capable of delivering true bass performance. In the SP-BS22-LR, they've added a structured surface to the 4-inch woofer. By doing so, not only is rigidity improved, so is bass accuracy. Engineers have also vented the pole piece, again improving bass response from the same size woofers in previous models.

Tweeter
To widen the sweet spot of the 1" High Efficiency Soft Dome tweeter, they've engineered a custom wave guide. Increasing tweeter efficiency, together with newly designed crossovers, allows the SP-BS22-LR's play louder using less power.
