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

This compact bundle pairs the Rockville BluTube tube amplifier with a pair of HP4S-8 4" outdoor/indoor speakers, creating a space-saving stereo system that works in tight installations where larger speakers will not fit. The BluTube pushes 25W per channel at 8 ohms through vacuum tubes for warm, rich tone. Bluetooth 2.1+EDR streams from 33 feet, dual RCA inputs connect wired sources, and a USB port plays MP3, FLAC, and WAV files. A two-band EQ, VU meter, and headphone output complete the feature set.

The HP4S-8 speakers handle 360W peak and 120W RMS per pair through a 4" polypropylene woofer, 1/2" Mylar dome tweeter, and rubber surround. Despite the smaller driver size, these speakers are surprisingly loud at 90 dB sensitivity. IPX44-rated ABS construction and stainless steel grills protect against rain, wind, and humidity, and gold-plated spring-loaded push terminals provide a corrosion-resistant connection. Metal swivel mounting brackets let you aim each speaker directly at the listening area. These fit under eaves, in small patios, bathrooms, garages, or retail spaces where a 5.25" or 6.5" speaker would be too bulky. If you need weather-resistant tube-powered audio in a small footprint, this is the setup.
