I wouldn't worry about "paper cones". Go here (I know the BT speakers aren't all exactly the Imagine line, but HAT describes their paper cones as waterproof) and see Hybrid Audio Technologies running their speakers in a fish tank...I would think the "paper cones on a bike where weather is a consideration" argument would be mitigated a bit by their tech. But I could be wrong. Still, my BT7P1s and 477s in my lowers have shown zero effects from the dousings they experienced last riding season...

 

So audio frog speakers are designed by one of the most well respected groups of people in the industry (and he looks just like Steven Spielberg so how can you not trust him right and for a show car or an environment I could control and appreciate the nuances of that speaker I'd be tempted since I have less sense then money at times but I just couldn't justify it in our application. The BT pros are pretty much my limit and really because of the lifetime warranty and fact that I truely love the sound of HAT speakers, they hit the sweet spot for me where as focal are a little too bright for my liking.

That being said, if you want to spend the money and you love the sound I say go for it, because my BT Pros sound a lot like everything else at 80 mph, but in the parking lot it's worth it to me so maybe frogs would be worth it to you, or Hertz Mille, or brax components, focal be.....

 

Brax products are nice but not $4,000.00 nice for an amp on a bike.
