Alright this is just my opinion so before anyone attacks remember this is just my opinion
As far as construction and quality of materials the Fosgate and the Kicker are superior to the Audiobahn. Now as far as the highest SPL. That all depends on a couple of things like how much power, and what kind of box. with the right box and power all three can be made to be very loud //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
This is just MY OPINION. Kicker is the higher priced product of the three, with rockford being second and audiobahn being cheapest price wise. Now all 3 make amazing products. The older audiobahns did have a few issues but they seem good now //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Overall I'd reccomend either of the three, rockford is the most readily available brand on the market with good reason, they make quality products at reasonable costs. But Kicker's higher cost is because of superb quality products. Audiobahn is relatively cheap IMO because while they are beggining to gain TONS of recognition, are still a new company in the audio world.
I personally prefer Audiobahn, I am running 2 Audiobahn ALUM10's and they sound great. I push them with a Soundstream LilWonder 4. They are in seperate .7 cubic foot boxes. They have better sound quality and are louder than my friends Kicker Comp Vr 10's with a comparable Kicker amp and bout 1.3 cubic foot ported box, my boxes are sealed. As far as Rockford is concerned they are the lesser of the 3 in all catagories. Kicker makes great products but are over priced. True there are better speakers than Audiobahn but you'll pay dearly for them. I love my ALUM10's and wouldnt trade them for anything. Hope this helps ya
To me there's no question, I run 2 Audiobahn AWT 12's with a MA Audio HC2502 @ 900 Watts per speaker and at about 3/4 volume it will produce 182.4 db, so to me it's simple. Don't take me wrong both of the other speakers are really good, but if you want clean hard hitting base it's all about Audiobahn
I have to say they are all make great speakers, but I heard one audiobahn 12, and it put a lot of bigger systems to shame, and that's coming from someone who loves kicker
182 db?? ****, I think he should be in some comps. That is by far the loudest system in the world. Maybe it was 128 db. Id hate to see what his car looks like! maybe an armored truck??//content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif
