Speaker Pod Basics

There's a lot of talk about best amplifiers and best speakers but I see very little about other best practices during installation:

1. I read somewhere about splitting the speaker pod and adding a bead of RTV to the seal. Does this make a significant difference? Is this a "best practice" that everyone should be doing?

2. Dynamat... Do I need acoustic material on the inside of the speaker pod? Does Dynamat on the outside of the speaker pod make a significant difference? Is this a "best practice" that everyone should be doing?

3. I see one vendor sells a "fairing system" and has you drill a "tuned port" in the speaker pod. I realize these pods are small to begin with and our replacement speakers are taking up more space in the pod. Is drilling a hole in the pod a good idea or a bad idea? Is this a "best practice" that everyone should be doing?

Johnny, having been through multiple audio configurations and pod tweaks on my 2015 and 2018 bikes, I can offer subjective opinions. The key word is opinions. All pod tweaks taken as individual mods or even in combination can change the audio acoustics and it is perceptible when listening to the bike at a standstill. Sealing the pods and then drilling a bass port seems counter productive. The whole purpose of the "split the pods and RTV the seams" is to make the the enclosure air tight. Sealing the pods and leaving the factory speaker wire grommets in place does produce a tighter bass response. Leaving the pods unsealed and porting the pods opens up the bass response, but it sounds more "boomy". Whatever the end result, the woofer cone can only disperse so much air and create so much sound pressure regardless of the pod configuration. After all, we only have 6.5" of woofer cone to utilize.

Polyfill whether stuffed inside the pods in layers or wrapped around the speaker basket also changes the audio acoustics. These mods also result in a tighter bass response and smoother mid-range frequencies at the expense of "thump" depending on the speaker you are using. Dynamat can help dampen the reverberations and noise generated inside and around the pods. Think of it as sound deadening rattle eliminating bed sheets. I think anyone that gets interested in sled audio goes through all of these contortions looking for the best "sounding" system after dropping a little coin or a lot of coin on audio gear. I'll admit it's a fun past time to keep idle hands busy.

With all of that said, any mod that you make to the pods and whether it is "worth" it, depends on the SQ characteristics that appeal to your ears and your brain. Now I'll refer you back to about the fourth sentence in the opening paragraph. Most of these mods will produce a discernible difference when listening to the audio when the bike is sitting still in the parking lot or the garage. But most of that literally goes out the window when you're running down the slab at 80MPH.... no pun intended.

Wevs is pretty much spot on.

I started the a RF kit in my ‘15, and after tweaking the amp a half dozen times and still not getting what I wanted. I added polyfil to the pods, it sounded better to my ears and seemed to ‘thicken’ the sound a little. Next I sealed up the pods with RTV, except the drain hole, which I think sounded better, the mids were more pronounced and ‘warmer’ and the kick drum had a little more punch. Then I added a set of MMATS in lower speaker pods and did the ultra flash to enable the fader. Everything basically went to shit at that point. After a having the fairing off another 1/2 dozen times, I scored a deal on 2 sets of ARC MOTO 6.5s which replaced the RF speakers in the fairing. After some tuning I am basically happy. It has plenty of punch and volume while still being clear and crisp. It all depends on your ear and what you are trying to achieve. It also makes a difference what kind of music you are primarily listening to, I listen to hard rock, classic rock, and metal mostly, so the deep booming bass isn’t as important for a complete sound stage.

On another note, each speaker is different, some do well in larger enclosures and others in small. The amount of ‘back pressure’ caused by sealing or venting an enclosure also varies by speaker. So it all really comes down to a bunch of variables and your ears.

Spot On !!!

Thank-You! Exactly the kind of input I was looking for. I can now make a couple informed decisions. I think I'll put my system together, seal the pods and see what I have. I can reevaluate later and port the pod, add polyfill or dynamat as needed. Again, thank-you wevsspot, thank-you r_einan.

Good luck!

I like your approach. Sealing the pods is a cheap mod that doesn't take a lot of effort. The poly-fil is easy to add at any time.
