Getting a P43 soon. In the Harman pamplet it list the minimum floor protection for each model. The P61 and P68 floor protection are listed at 24 x28 while the P43 is listed at 32 x33. With the P43 being much smaller than the P68 and P61 why would the floor protection be so much bigger. I was going to by a floor protector tomorrow but wasnt sure on this.
