Where does our expertise come from? We've done our homework over 25 years of specializing in fitness sound and lighting/video solutions. We've spoken to thousands of Fitness Professionals and have added their experiences with gear to our own.
Our fitness-specific knowledge of such things as sweat exposure, headset recommendations based on number of classes per day, or what type of speakers and amp are needed for a certain room size are some examples of what sets us apart from other stores.

Equipment Recommendations Get the right equipment and save money by letting AV Now's Fitness Sound Experts recommend the right equipment for your application. We're here to help. Local music stores and sound installation companies often don't have the knowledge - or carry the right products- to make a recommendation that's good for a fitness or aquatic sound application. Many websites offer you equipment specs and pricing, but it's up to you to figure out if the product will work for you.
Avnow.com only stocks Fitness-Rated products. If you need pre-purchase advice, we're here to help guide you with recommendations. If you have questions about any of our products, simply call, email or chat with us.
Fitness Sound Systems AV Now created the template for the modern group ex fitness sound system 20 years ago. We offer a full line of fitness sound systems for every room, class size and budget. Our systems are updated as technology changes but the principles remain the same: ease of use, great sound and great value.
AV Now Fitness Sound Systems are now imitated but never truly duplicated. We have over 5000 Fitness Sound Systems in use across the US and around the world.We use our knowledge of what works best for non-technical users wanting great sound from a durable system. Sound companies, music stores and some professional installers may be good at offering nightclub, musician/band or home theater sound - but don't have the real world knowledge of what works best for fitness sound. As mentioned, most online gear sites leave it up to you to figure out what to order.
AV Now sound systems have easy-to-use components specially chosen to sound great in fitness environments. Customers tell us they sound fantastic and they're often less expensive than what a local sound installer or music store quoted. And, rest assured, our sound systems use the right gear.
