I too am curious why...the Echo PB550T is rated at 70db, same as the Stihl BR200. Are the specs not "accurate"? Or does the "basic sound" of the engine itself fall into an "irritating" frequency versus other brands. LMF....yeah, even without the comment from ric, I was onlu interested in a tube-mounted throttle.
Yes I would say that they are accurate. If you stop and think about it The 550 is 465cfm the 200 406cfm. The 550 is rated at 163 mph average the 200 is 132 mph average and both are 70dba so in reality there pretty close as far as cfm goes and sound and there is a little difference in air velocity although not that much. The thing I look at and the big difference between the two is the Echo uses a 50.8 cc engine to produce it's spec's while the Stihl uses a 27.2cc engine. What's wrong with that picture????:smile::smile:
As for my comment about hearing one run......... I came home the other day after doing some of my lawns and was in my garage watching some tv while I was cleaning a trimmer and heard an ungodly noise and couldn't figure out what it was so I opened the door to look and across the street there was a guy from one of the other Lawncare outfits clearing a driveway and he was using a 500T and I swear I could have stood next to him with my BR 500 running and you wouldn't have been able to hear my 500 running that thing was so loud. That 500t sounded absolutely terrible. Now I will say it was doing a kick butt job but I would have for sure had muffs with that thing.
