Introducing Our New Sound Room

Want to know before you buy?

Come in and try out your next purchase of a microphone or monitor.

With our newly refurbished sound room you can experience the several acoustics materials and the impact they have on the reflection of the sound waves.

If you really want to know what your voice or instrument will sound like with a room’s acoustics first hand, then it’s a must to stop by our showroom and try our sound room.

Bring your own equipment or ask us about your demo options with our dealers.

24 hours: 3 Events

Capitol Hill Block Party

Boeing China Eastern Delivery

Museum of Flight



What a whirlwind of a weekend! Starting with a sound check for Shacia and Zuri Marley at the Leafly “Vibes” VIP lounge, it was a pleasure working with Bob Marley’s grand daughters again. With the sound check checked off the list, we jetted down to the Museum of Flight for a night filled with a beautiful celebration for China Eastern. After striking that event, we headed back to home base to stage the early morning Boeing delivery for China Eastern’s 20th 777.  With that wrapped up, it was back to Capitol Hill to finish off the weekend listening to great music and enjoying the Jamaican atmosphere in the Marley Naturals/ Leafly Lounge. A big thank you to everyone for all their hard work, long hours, and dedication to their passion.

We call that a success!
