Midbass vs Subwoofer. 10"

lpreston · Aug 1, 2021

So I have been looking into building a bike to compete in the Featherweight class. They don't divide classed by watts, but by speaker qty and class of the driver. Here are the class specs:

FEATHERWEIGHT

Up to 6 overall speaker count

SADDLE BAG RESTRICTIONS

Sealed saddle bags ARE NOT PERMITTED. NO SEALED BAGS! TMC/SOS officials must be able to see inside your saddle bag at which time the speaker must be fully visible. No removable/partial, etc enclosures. Any issues will cause for possible disqualification or moved to another class which is in discretion of the SOS.
up to (1) one single 10” mid-bass/ midrange speaker per bag or dual 8” mid-bass/ midrange speakers per bag. (NO SUBWOOFERS)
Saddle bags MAY have a port design that may exit out from the interior of the bag.
You may also do minor modifications such as add fiberglass, sound deadener and braces to enforce side walls.
Saddle bags and side covers may be molded together where the bag and side cover meet.
Saddle Bags and saddle bag lids may not exceed the width of 9.25 inches at any point.

So in conversation, I asked how do I determine if a 10" speaker is a 'midbass' or 'subwoofer'. I was told that the manufacturer will label it. It's not spec-driven at all.

With that said, suggestions on 10" 'midbass' drivers besides PRV? Not worried about material for waterproofing.

I would think any application is "true" spec dependent. I mean if a midbass in a two system with 3/4 tweets can't play cleanly past 400 what use is it?

I always believed it was the FS and the frequency response range. Where a 10" subwoofer typically plays 20hz +/- up 200hz-800hz on avg, while mid-bass driver typically are not designed to play much lower that say 40hz and that's the really good driver's. Almost all I have seen in powersports play well pass 800hz and can be used in a 2 way set where you would never mate a tweeter to a subwoofer. What brands are you looking at? I know for me the new DB Xpert 10" with the carbon fiber cone is king right now.
