Although I appreciate the testing and time involved in doing this, there is no logical or technical explanation for what you're seeing/hearing here. Having the speaker mounted to the inside of the pod will take up approximately .5% more air space because of the speaker rim being on the inside of the pod vs the outside of the pod and that in no way will make an audible difference to your ears.
Now what could be happening and would be interesting to see/hear from you is whether the woofer surround on the internally mounted speaker is actually hitting the pod causing what you are experiencing.
Good point regarding the external speaker rim. The upper section of the speaker soft rubber rim is actually "touching" a little bit of of the upper rim of the inner faring shroud and I was a bit concern about that, so I actually performed one more test, by uninstalling the entire right speaker pod & suspending in mid air tied only by a pair of strings and run though another series of sound tests & guess what, sound test results were that same per my initial tests...what's interesting is, that bass response, that "thud" is more pronounce on external vs internal...
What I noticed & observed when mounted internal is the air "gap" between the speaker and the mounting rim & the four inner pod mounting points, & of course when mounting external, it leaves no air gaps between speaker mounting rim & pod. So I am not sure what is making or causing the sound listening experience to differ enough.
I will be completing my final install of the RF PBR300X2 in the next two weeks & will rerun the same sound tests before & after amp install, & if time permits, record the process.

Reason: spelling
The problem is the air gap...if you mount the speaker inside the pod.. you must grind off the mounting posts so that it seals.. or at a minimum use weatherstipping to make a seal
DC2009EGUC: Interesting test. I think I am one of the few that have installed the Kapps 62.11i speakers on the outside of the front pods where the stock speakers go. And I must say I do hear good bass sound and good "punch" and "thud". I do not have anything to compare them to other than the stock setup but I agree with you findings. I did about 200 miles today and they sound very good without a flash. And again, I don't have anything to compare to so I there is a good chance the correct flash would make them even better. When I do take the pod back put I am going to put a hand full of Polyfill down in the bottom of the pods as UN has suggested.
Bertk - It looks like you seem to share the same observations I did...thanks for sharing...There's got to be an engineering/scientific sound reason why Harley Davidson designed these speakers to be mounted external vs internal...

My guess would be cost played as big a roll as engineering , it most certainly influenced it.
With the kappa's installed on the outside of the pods, they did not sit flat. I had to file away some of the plastic speaker ring to avoid hitting the top grill screw so the speaker would sit flat.

Hi Bertk - Thanks for the tip, I will need to so the same on the kappa 62.11i...did you by any chance replaced your tourpack rear speakers? If you did what brand and size did you use.
