I can't say, I haven't tried them all. I did buy HogTune amp and speakers for my FHLTC, and really liked them, but still couldn't hear clearly at 80+ MPH. The next year, my wife bought the wrong non-refundable (special order) Hog Tune lower kit. I called and spoke to Scott at Hog Tunes, and he was very sympathetic and helped me get the right impedance speakers, I only had to pay shipping one way and nothing else (they also included another wiring harness for free). Better yet, they said if I wasn't happy they'd see what else they could do. Customer service as good as it gets. The best part of all is that even with the amp powering the lowers, and the stock HK powering the fairing speakers, I need nothing else, not the tweeter bar, not another amp, nada. Clear sound up to any speed I'm good with!
