According to Sony, these compact amplified speakers are supposed to fill every corner of your room with sound – despite their small diameter of just about 5.7 inches across.

The SRS-BTV25 is designed to play sound streamed from Bluetooth-enabled devices, while the RDP-V20iP is an iPhone/iPod dock/charger which can be controlled via the included remote control.

Both models feature a 2.2″ woofer and a 0.78″ tweeter. They each deliver 13W of sound. The RDP-V20IP can be powered up to 5 hours by rechargeable batteries. The SRS-BTV25 has audio jacks and a USB port to work with a variety of non-Apple devices. They’ll come in black, white, or red (only RDP-V20IP). There’s no word yet on pricing or the official release date.

MBL’s 101 X-treme speaker system cranks out sound using a set of four custom built towers. Two of the towers feature pairs of the company’s proprietary omni-directional drivers (like the ones in their smaller 101E speakers), while the other two will rattle your bones with a stack of four 12-inch subwoofers.

Handcrafted from quality materials such as carbon fiber, aluminum, steel and wood, these mammoth speakers truly live up to their “extreme” name tag. The whole system is built-to-order and requires about a month to construct from start to finish.
