Would you buy an expensive sports car if it didn't come with shock absorbers or padded seats? No? Then why plunk your super-accurate, high-performance studio monitors down directly on your desk or stands? Stick Auralex ProPAD XLs under those monitors, and you'll see what we mean - you'll wipe out resonances and vibrations that keep your speakers from speaking properly, and you'll get perfect positioning in the bargain! Maybe you like the sound of a high-powered monitor trying its best to buzz its way off of your desktop, but we sure don't. That's why we swear by ProPAD XLS.
