Led Sound Activated Computer Fountain Speakers Fountain Speakers It&#39;s a Fountain of Sound, waiting to be your own private Bellagio with dancing waters at your command. The speakers have aluminum cone 1" drivers set below 5-1/2" tall clear acrylic chambers. The chambers are filled with fluid that responds to a sound-sensitive fountain pump while red, blue and yellow LEDs do the same. Call it the Liquid Disco. Input is through a 40" split cord with (2) 1/8" standard miniplugs. Power is via a 44" USB cord. Speakers measure 8-1/2" tall x 2-3/8" x 1-3/4" on a 2-1/2" dia base.
