BluTube Tube Amplifier/Home Theater Bluetooth Receiver + (2) 4" Speakers

This package matches the Rockville BluTube tube amplifier with a pair of HP4S-8 BK 4" outdoor/indoor speakers in black, built for locations where space is limited and weather resistance is required. The BluTube amplifies at 25W per channel at 8 ohms using vacuum tubes, producing rich, warm playback through Bluetooth 2.1+EDR, dual RCA inputs, USB media, and a headphone output. Front-panel bass/treble controls and a VU meter let you adjust the sound in real time.

The HP4S-8 BK speakers squeeze 360W peak and 120W RMS per pair out of a 4" polypropylene cone with rubber surround and a 1/2" Mylar dome tweeter. IPX44-rated ABS cabinets and stainless steel grills take on rain, mist, and wind without fading or corroding. Gold-plated spring-loaded push terminals stand up to humid environments, and swivel metal mounting brackets direct sound exactly where it is needed. The black finish makes these speakers less noticeable on dark surfaces, fences, and garage walls. Compact enough for a small balcony, a bathroom, or a hallway, this kit proves that a tube-powered two-speaker setup does not need to take up much room to sound great.
