Having vibrations can cause new frequencies to be created. The point of isolation pads are to eliminate vibrations that occur between your desk and the studio monitor. They would normally cost you an extra $20 if they didn’t include them, so free pads is a good thing! I’m glad M-Audio choose to include the isolation pads. With the BX8 you’ll get a few manuals along with a set of isolation pads. What Others Think About The M-Audio BX8 D2.After reading a numerous amount of positive reviews, I decided to take a closer look at the BX8 D2. The M-Audio BX8 D2 supposedly can supply a clear, accurate sound for a price under $400. With any sort of pro-level audio equipment, you get what you pay for. The AV-40 was an atrocious set of monitors that cost less than $100. I was a bit skeptical to review an M-Audio monitor because in the past they have released the Studiophile AV-40. There are just so many cheap-o monitors getting pushed out that might sound like a good idea to buy based on their descriptions, but once you finally make the purchase, they sound horrible! It can be difficult to find an affordable pair of studio monitors that actually sound good.
