From the sounds of it, you have some mid bass coming from the fairing as well. What mids are you running?

 

Just another thought, (cause Im a wild and crazy guy) what about a set of the DD 608 sub in your pods would that work?

 

Sorry the DD506 sub

 

My mids are just a pa mid. Area 51 brand as they take a lot of refinement to get the sound. Lose the sub idea, not practical or even worth the thought.

 

Thanks, just a thought!

 

Nope! Not enough air space in the pods for a proper enclose and those things are MUCH beefier than a regular 6.5 coaxial.


So with respect to frequencies and differences between pro audio speakers and regular coaxial or components. Specs and frequency diagrams don't always tell the entire truth. But one thing to consider when discussing if a pro audio speaker has a "warm" sound vs. something that would sound like it's coming from a megahorn is the mid bass and lower mid range. A good mid bass sound in the 80hz-200hz range will get you "some" bass sound, lower midrange in the 250-500 gets you a nice warm sound, and mid range in the 500-2000 range gets you rich vocals. By design a mid range speaker (like MMat, Hertz SV, DD VO, etc.) will spike in the upper mid range frequencies and can cause that screetching vocal sound that over powers everything. But when tuned properly you can get some decent midbass, and really good warm midrange sound.

Check out the two graphs attached. One is for the Hertz Mille and the other is for a pretty traditional pro audio 6.5 midrange. What you will see in the pro audio speaker is a higher sensitivity in that that mid bass and mid range that stays pretty consistent through. While the Hertz Mille will for sure toss out more bass, the lower frequency graph means it needs more power to reach the same volume as the pro audio speaker. This goes back to what Slye mentioned about efficiency and needing less power. I run less than half the wattage of most guys here, and likely have the loudest bike with less power! Efficiency.


Going back to T's concern with the Rushmore bikes and not being able to tune, you also have to consider that the Line Leveler is there to tame the spike in midbass the stock EQ curve has. So if you have a speaker that can't produce as much bass, then you eliminate it's ability to have much mid bass with the LL what you are left with is nothing but vocals from the pro audio speaker. I'm gonna bet for T it sounded like crap. It takes some creative tuning and the right speakers to get past that. In Miami up until recently everyone used the dealer flash vs. a line leveler to keep "somewhat" of a straight line. To the point that we've purchased the hardware to do flashes at our shop for those that don't want to spend the cash on a DSP. Soon we'll do both!

Ok that's probably more confusing than helpful. Bottom line, you can get SOME warm sound from a pro audio speaker.....enough of what you can hear on the road, but ideally combined with something else you get all the frequencies.

 

Alex,

Thanks, funny thing is, in the short time I have been on this forum, I learned so much that I actually understood everything you wrote!

I know when we talked you also suggested the AD CX62s for the lowers. I take it with your experience, they should help fill the void of the MMATs.

 

You could do it either way. The MMats and horns in the fairing with AD's in the lowers but that's really to round out the sound at slower speeds, on the highway there's no way the AD's will keep volume wise with the AD's. The other way is to do the AD's up top and then the MMats in the lowers, since they are louder it compensates for being further from you in the lowers position and can be heard "better" but still from the lowes position I don't care what you put there you will lose details once you hit some speed.

 

Is there another PA speaker that would keep up in the lowers?

 

what you do you mean? When running the AD's or MMats in the fairing?


I don't care what you put in the lowers, sound will negligible and back ground noise from that location when you are on the highway.
