Posted by Benjamin Holt on Apr 08, 2024 I have run many different midrange speakers, from prv, rockford, dd, and diamond. These by far have to best value, clarity is insane even playing from 80-8000hz. Have 4 paired up with a set of d25 tweets and jfx35 midrange running on a jp284. Best high output set up I have ran yet. 5 Hexicone pro 8 Posted by Alexander R on Sep 27, 2023 These things sound outlandish, absolutely amazing, I’ve tried several 8 in “pro” series subs all rated for 275 watts rms, and these easily sound the best up and and 1 mile down the road, and they have the most bass out of any 8 in speaker I’ve heard also. Play highs clear as glass and very loud given the power, play lower notes good for a speaker, and that mid ranger is beautiful. 10/10 recommend, will buy more. 5 Hexicone 8s Posted by Wally on Sep 22, 2023 Great quality, Sound amazing, and the looks are perfect. hard to beat at the price point.
