Some critics will say that these tiny speaker companies use cabinet kits and then pop-in other company's speakers. Tommy rebuilds drivers and tweeters extensively and designs and builds his own cabinets. Hand-crafted beautiful work. Danny holds patents in what he's designed working insync with Rythmik. I use his subs combined with custom built cabinets. I picked out and ordered the veneer and got to see the progress of the assembly. I also got involved with some DIY.
For me, this has taken the hobby to a new level of enjoyment and interest. I've been long done with the big brands, heavy marketing, and promises.
