A5 panels are 2'W x 5.5'H each. A5 panels are the most common panels system used to isolate drums. Their height allows them to cover cymbals, and reduce more sound than the A4 panels. Shown here is an A5-7, 7-section system. The A5-5 is the most common set-up for a standard 5-piece drum kit, and usually goes half way around. Larger kits may require the use of an A5-6 or A5-7. The A5 panels are also used extensively in our IsoPacs. (A5-5 pictured)
