SpeakerCrafts’s latest outdoor subwoofer aims to go low – really low, as in subterranean. In fact, this woofer goes so low all you can see is a small, hooded port that’s exposed above the surface of the ground. The rest of the “BoomTomb” is buried underground for a near-total stealth look. Inside the BoomTomb is a 10-inch long-throw woofer, and a hood covers the top of the port to protect the stuff inside from the elements and curious critters. A dedicated 250-watt amp gets to stay inside next to the rest of your electronics where it is (hopefully) warm and dry. No word yet on pricing.
