My speakers arrive on Tuesday this past week and I just put them in today. It took me about an hour to do the entire install.
Before I removed the fairing front, I put in a CD and got out my db meter and setup a test. I picked a certain song and stood at the rear of the bike with the TourPak off and the db meter at my chest pointing forward.
I had the volume set with the standard treble and bass, not much bass with the stock speakers. I got an average reading of about 84 db. This was done on the slow scale C weighted.
After I installed the new J&M 7.25" speakers, I did the same test with the same volume and all settings the same. This time I averaged about 87 to 89 db all other things being equal.
Not bad for an improvement. I can now have a bit more bass and I can even cut down on the treble a bit with the new tweeter/mid grill speakers. These seem to be a bit brighter in the sound than the stock speakers and I think that might be a good attribute for riding.
I'll be riding tomorrow to test them out and I'll take a picture of them installed and post it here in this thread.
So far for $219.95 delievered to my door, I'm impressed. I bought these from Dr. V-Twin and they were very good to talk to about different models etc and seemed to know their stuff.
You reuse the stock speaker mount but remove the cloth grill and use the mount to hold the new grill and two grill speakers in place. Then you screw the round 7.25" adapter to the original mount and screw in the new speaker. This was a true no brainer, very easy to do.
I'll get pictures and a road test out tomorrow.
