We just tested a pair of 4-1/2" x 6" on a 680 HP boat and it was at 88 Dba according to the local authorities!!
We were really pleased with the real world test!!
Let us know if we can help, running a summer speacial right now.

I'm running a set of thru transom Zoomers on my 720 HP ProCharged motor. Have not had a decible check but does not even get a look from the authorities. I don't think we lost any power 5400 RPM at just about 90 on GPS.
