Good to see you have both channels sounding good using the HPF settings. The reason BT put these adjustments on the LL was to give us the ability to compensate for the crappy software updated HD releases.

What I have found with the Mille's in the lower on the SG they sound very good parked and at slower speeds. Between 50-60 they really start to fade and past 60 they become background noise. Still better than having only two speaker up front.

When I had the BT6.5's in the Ultra TP pods they sounded way to bright. When I put them in the SG lower and liked them much better, not nearly as bright. So I think you are on the right track by moving the BT6.5's to the lowers and the KRC's to the TP pods and run them in parallel.

With the TP pods being vented the KRC's should sound a lot better than in the lowers. I think the KRC really need more air moment to preform well.

Let is know how it all works out.

 

The Hertz SPL SV 165.1 Mid-Range Drivers might be a good choice to get more volume from the lowers.

 

Now this PA discussion seems to be showing up a bit more and more as drivers that will compliment an already solid sound platform.

Thinking this might be a very good decoder ring for a few locations on the sled. Gonna pay close attention to this as the voices in my head r getting a little fired up. Shifting a few things up in the weeks to come.

So I posted recently that speakers for the most part are selected based on how your bike sounds parked. Like we've said in other posts the vids are the bike sitting there and not moving. We've had folks pick speakers for the tourpack pods because it was good bass and provided balance, or in the lowers the motos "hit hard" we've posted ---- all very true. Now has anyone here listened to a set of Hertz SPL's in combination with a coaxial? Do you still get the same balance? Then consider the bikes that shine that are using these types of speakers (and sound good...also parked!! ) it's part of a COMPLETE package vs. get more volume from your lowers with speaker xyz or get more bass from your lowers from xyz. It's NOT about a specific speaker or brand. For example...do you need more bass from your lowers if you are running a tourpack subwoofer? Probably not. So think in terms of your entire bike.

SPL's play very loud, they also play in a very limited bandwith....off the top of my head it's 100hz - 10,000hz. So to say you will get more "volume" is absolutely correct but at 80mph even that increased volume with a decreased bandwith is limited background noise. Could it be complimentary...quite possibly but I can assure you that focals in the fairing, and SPL's in the lowers (and nothing else) parked will sound like crap....and just noise.

If I'm Steaks I leave it alone. It is what it is with lowers, considering you already have $700 speakers a foot from your face! If I wanted to show off a little, I'd put the JM tray, a second amp and put the motos in the back to have that "balance" and let the focals rip in the front off the 4180. Only if you are considering dropping more cash into the system, because if you run the SPL's they would need their own channel anyways....I would never run my fairing and tourpak pods in parallel.

 

Yes, I have heard the difference myself, the fairing speakers NEED to be on their own and my bikes future will see another amp for the rear stage to run lids and pods so nothing is run in parallel from then on. I'm going to try the second set of focals in the rear pods without any lowers and then the BT 6.5 in the lowers in parallel with the lowers just because I have them and it's easy to do. Like I have stated before, I'm more interested in what I can hear on the road. I can't explain how bad a quality set of speakers in the lowers pointing at your thighs and engine sound(with the fairing faded out), can't justify leaving them there especially when I can't even hear them at 75mph running full power from a 4180 amp. This morning I faded to just the lowers at 75mph and it sounded like a little transistor radio was down there somewhere, lol. I see my second set of KRC's going to a better home in someone else's fairing and something else behind me in the tour pods and something in the lids over the winter.

 

You know what's so damn awesome about your response steaks, that it is so damn practical that it breaks the traditional thinking!!

 

AS much of a pain in the *** it was putting it together and making it fit, when I hear this stuff I am glad I went big on front stage. I have second guessed that so much lately that this situation gives me the reassurance to not deviate from my original plan. I'm with steaks though. Parked my stuff is hardly up other than to show what it sounds like as I do not have and wont buy a go pro for riding my bike. So is the big moral to the story here lowers are worthless after 60 then no matter the speaker?

 

Before u guys start tearing shix out of your sleds, how much time r u spending above 60?

Half way to Austin from H-Town with a big group and stopped cause the low beer light is flashing, but just checked my computer for average speed and it was 53 over 110 miles of riding. I'm more of a social rider so gonna target the speeds that I spend most of my time riding.

Yet another variable in this very dynamic thing called sled audio.

Awesome info Haze. And no, I haven't heard a combination of SPL's and Coaxials.

Just thinking out loud in terms of a complete package. From the little I know the coaxails try to deliver a full range of freq's. The SPL's will deliver mid-range and volume. So I need to ask myself whats missing from this package, and it's Bass. And depending on the coaxial/tweeters it could be upper mids and highs also. So the next step would be to add lid/bag speakers for bass/thump.

On my SG with the KRC's in the fairing and Mille's in the lowers I have everything I need when parked or slower speed. What's missing is volume from the lowers at speed. When I go to the next phase to add lids I was thinking of putting SPL's in the lower. So the KRC's would cover the Highs, the SPL's would add more mids, upper bass and volume. Then add a pair of 6x9's in the lids for bass powered by a small amp that would hopefully fit in the fairing. Does this sound like a plan worth considering?

That sounds like a good plan.

 

Well I didn't leave thinks alone, lol. I put the KRC's from the lowers into the rear pods again, nothing in parallel, full power from a 4180 amp and went for a ride.

I was surprised again thinking the rear pods didn't do much at speed, well they do a hell of a lot more then they do in the lowers!!(remember this is solo not two up) I could tell they weren't there when I faded them out all the way to 75mph(couldn't go any faster where I rode). At that speed they were more fill then sq but at lower speeds you want them AND parked they sound great even alone unlike the lowers. If I didn't already have them I would not waste any $$ on lowers if your looking for sound at any speed, they look cool and ad some fill sound but not worth it in my opinion. Keep in mind that my bike is loud at idle so as soon as I start it sq starts to go out the window.

So this is what I have learned:

Lower fairing speakers suck, lol

One set of quality speakers in the fairing and a good amp is better then two sets of quality speakers running in parallel off of a quality amp.

Two sets of quality speakers running off a quality 4 channel amp is better then 6 off the same amp.

Build your system around your fairing speakers at speed, I'm pretty sure that if you tune your system to sound as good as it can at highway speed with just your fairing speakers and amp by themselves, THEN build around it to sound as good as it can parked with additional speakers and amps. I don't think you can hurt your highway speed sound with anything you throw around them(as long as you don't touch them), and I don't think your fairing speakers being tuned for speed will hurt the other 4-6 other speakers tuned for parked.

My bike sounds as sick as it ever has at speed and parked(really sicker parked)(not saying it can't sound better and still could use some more bass) running with 4 speakers(none in the lowers) then it did with 6.

Next will be another 4 channel amp to run the lowers and lids(or maybe just a 2 channel amp for the lids) and of course lids and speakers but not till the snow flies around here. Think for now I'm going to just throw some grill covers over the lowers just for looks, lol.
