I've purchased numerous acoustic panels from Acoustimac over the years, and they have maintained the same high standard of quality, performance, and customer service throughout. Their acoustic panels and bass traps have been the most important factors in elevating the acoustic performance of the rooms I've worked in. Treating a recording space/mixing room/ listening room is the single most important thing you can do to acheive great sound--even more important than the actual equipment in use. Acoustimac delivers top-notch acoustic treatment specifically designed for this pupose at an unbeatable price point. Highly recommended.
