  1. Stanley @ 80kaudio

    Speechless!!!! The sound reproduction the Tumult 15” produces is amazing…this is a true definition of SQ meets SPL …it gets loud and still maintain its superb sound quality, I smile every time I hear this subwoofer play. And the best part; you don’t need a million watts to get loud…all u need is 1500 watts and put this lovely beast in the right box and hold on because it will bless your ears with the sexiest lows you will ever hear. To the folks at Adire – Great job!!!!! Keep up the good work!!!!!

    Awesome sub, thing digs deep with authority and makes a great addition for any system. I’m using it on my MECA Competition Car and it performs lovely. Great quality from Adire!

    As a proud owner of a Mark II Brahma, I was very excited to see Adire return with refreshed products. I took the plunge and picked up a 15” Tulmult for HT use. After 6 months of use I am still impressed by the amount of air this Tumlult moves while providing clear and accurate LFE reproduction. I highly recommend taking the plunge if you are on the fence. You will not be disappointed.
