If these don't give you the angle you were looking for let me know. I rode to work today. I just bought the empty fairing from reckless and bought the sony head unit and audiobahn 5.25" speakers.
I had the hogtunes radio that was made for the ms batwing. Volume was an issue with that. With my current setup I can hear most songs at any speed. All depends on the quality of the source file. But there is very little bass, but I don't have an issue with that, at highway speed I doubt you could hear bass anyway. If there's anything else you want to know just let me know, like I said, have the bike here today.
sorry to jump into you coversation but roger you said there is very little bass but its nice and loud.
something to keep in mind for anyone looking into speakers:
round speakers give crystal clear/crisp sound
oval speakers give more bass but not as clear/crisp as a round speaker gives.
it would be awesome if you could do round and oval in a fairing and blend bass with clairity.
but if i had to pick one or the other i would go for round speakers for the clear/crisp sound.
