Got my JBLs and installed them....WOW what a difference. Worth every penny

 

Was the swap a direct replacement, or were any mods needed? Thanks Doc

 

Took old ones out, and put JBLs right in. Took about 10 min.

 

What model JBL's did you install? Any more of a deeper sound that with stock? I may want to do the same mod. Where did you get 'em?

 

They are JBL GTO 527's. They have more bass, and clearer sound. Better all around. I go tmine on E-Bay for around $60. to my door.

 

Forum Members ,,,,,

in the J&M Corporation R&D shop today we compared side-by-side the JBL GTO527speakers against the stock Harley speakers from a 2008 Ultra Classic that I just took delivery of last Friday ,,,,

we did this in the speaker J&M comparison board shown here with a switch so we could switch back and forth between the two sets, using the same audio source to get an exact comparison ,,,,,

in this box these two different speakers sounded pretty close to the same, with the edge going to the stock Harley speakers as theyput out a little more sound, especially in the midrange frequencies ,,,,





then we listened to the stock Harley speakers playing at maximum volume in our shop mounted in a 2008 Ultra and made notes of how they sounded ,,,,,

then we installed the JBL GTO527 speakers in my new 2008 and made notes as to how they sounded ,,,,,



then we installed the J&M #HCUS-06GT speakers in the faring of my new 2008 Ultra and again played them at max volume in our shop with the exact same track of music on the exact same CD as used for the previous speakers ,,,,,

Each time we installed the various brand speakers we put the fairing all back together so that we were comparing apples to apples ,,,,,



the JBL’s and the Harley speakers mounted in the bike sounded pretty close, with the edge again going to the stock Harley speakers ,,,,,

but the J&M’s really did beat the snot out of both of them, not only were the J&M’s a lot louder at max volume, but they put out significantly more sound overall, better midrange and tighter bass response than either the JBL’s or the stock 2008 Harley speakers ,,,,,

those of you who think I might have other motives for doing this test,,,, well, just keep on thinking that ,,,,, but believe me when I tell you that all of us in the J&M R&D shop performed this test objectively and without bias ,,,, we just wanted to see for ourselves ,,,,,

I hope you're kidding

 

XXXracing ,,,,,

not kidding at all .,,,, we do this stuff for a living and I am not in the habit of lying ,,,,,

as I have posted here many times, we do our research and we design our speakers specifically for each application, and it would be very unusual for a replacement automotive type speaker to soundas good as the J&M's,,,,,,

 

John,
There was concern that the JBL's would not fit the rear pods. Do J&M's fit the rear, or is there a special speaker for the rears.

 

Dougger ,,,,,,

yes ,,, the specific speakers that J&M offers for the rear position will fit, but be sure to see the Harley Classics page on our website for the spcific applications ,,,,
