The 78" x 66" Hot Tub Cover (Long-edge Fold) is an exact Master Spa Factory OEM replacement. It is specifically designed to fit your Master Spas® hot tub. This cover is extremely energy efficient, as it's made of a 1.5-pound foam density, six-inch thick foam insulation (which tapers to 4-inches along the sides), and a full-length heat seal. It has been upgraded to include two rubber grip handles and is made of a high quality marine-grade vinyl covering that is mildew treated.
Note: This particular cover folds along the longer 78" edge. If you need a cover with these same dimensions (66" x 78") but that folds along the short edge, try our 66 × 78 Inch Hot Tub Cover (Short-edge fold).
Water can be rough on speakers. The 6.5-inch 2-way marine speakers are ready to take on whatever your Master Spa Hot Tub Series will throw at it.
Customers will enjoy clarity of audio and can rest assured that these speakers will not be destroyed by sun or an the occasional accidental splash of water.
