We are here to help you better understand the benefits of Stack•M. If you have additional questions, reach out and contact us. 

Stack•M is the new wireless multiroom sound system.
From the living room to the backyard to the beach, the Stack•M is a set of stylish, hassle-free speakers that can go with you anywhere. Stack them for more powerful audio, split them apart to listen around the house, or pair them for true surround-sound style. The more you have, the more you can play. No apps or Wi-Fi needed.

We offer a 30-day satisfaction guarantee (from the date your Stack•M is received) to return for a full refund (less shipping and handling fee). For more information, please refer to our Return Policy.

If you'd like to return or exchange your Stack•M for any reason, please visit our online return portal.
