The efficient use of whiskey barrels is what makes the Pioneer S-A4SPT-PM Pure Malt Speaker an extremely intelligent speaker in terms of sound quality. Engineers had discovered that solid oak wood from whiskey barrels have acoustic properties which is what led to this amazing creation later. These wooden barrels have a mature mellow tone that had been beautifully finished as a speaker you would want to flaunt indoors. After all, who wouldn’t prefer highlighting the luxurious quality of sound and craftsmanship from one single device at the same time! Playing music at your indoor parties will now be a sophisticated encounter with this fantastic speaker there.
