From: Eric Roth < Sent: Tuesday, August 28, 2018 5:48 PM To: Jeffrey E.; Jay Massar Subject: RE: G550 sn 5173 SUBWOOFER PLACEMENT There is already a subwoofer in the aft section of the divan and there is enough volume of air within the total cavity. These subs are designed for Gulfstream to require minimal air movement as many of the subs are located under the seat base with approx. less than 2 cubic feet of volume. Best Regards, Eric ERIC H.

I was hoping that we had space underneath the L/H #2 seat, but this is already occupied. My suggestion- you have a subwoofer as part of this system design and it needs to go back for optimum performance. We only see two opportunities and they are both in the fwd arm rest of the L/H divan: 1. Fwd side (we would need to create a speaker grill to allow acoustic penetration) 2. Aft side (see attached engineering drawing) where it is "visually concealed". Since low octave frequencies are non —directional ( it is not nice to roll your eyes at me ), I advise installing as drawing. Please provide direction so that we can move forward.
