Philips Bluetooth 2.0 Bookshelf Speakers

Two Philips bookshelf speakers that look like speakers
Aux-in or Bluetooth v3.0, spending on your wire tolerance
Each speaker is about 10" tall, 5" wide, 6" deep, with a 3" woofer and a 0.5" top-mounted soft dome tweeter, about the size of a gallon of milk
20W RMS total power, which makes it louder than anything else on your bookshelf
Model: SPA4270BT/37 (Philips puts "/37" at the end of a lot of model numbers - why? Because it's the atomic number of rubidium? Casey Stengel's uniform number? The number people are most likely to blurt out when asked to choose a random number between 1 and 100? What secret does 37 hold, Philips?)
