Speakers are one thing but as I have said numerous times....so is cab design and construction. Throw the exact same speakers in all the possible cabs then account for front and rear loaded and I promise you no speaker will work perfectly for all of them. Our cabs are no exception and I have been very vocal about it. Front loaded needs G12K100 and rear loaded needs a hemp cone. That combo is bliss. Reverse that combo and you get a bad result. Speakers are definitely important but so is cab construction. The two work together far more then most people realize.
