This beautiful pair of Wilson Audio WATT / Puppy 8 speakers is finished in Titan Red with black hardware and grills. They’re a used, one-owner pair that we originally sold and have taken in on trade.  The W/P 8s are a much easier impedance than later models so not as demanding of the partnering amplifier.  There’s no better sounding speaker for anywhere near the price.  Includes original packing crates.  Please contact us for details on local delivery and setup or shipping costs if you’re outside of the DFW area.
