Just looking at specs, there is no listed 3dB point on his FRs for his Speakers. He simply lists 70Hz-18kHz for the 210 monitor, and 60-18k for the 210 tower.
I would never even consider those speakers without seeing what it is doing.
Strangely, this is exactly why I didn't buy from Eric and Tekton. No reference information to support the subjective claims of how amazing they are.
Consider guys like Dennis M, Dave F, Jim S, and even the late Rick C... they all make information on their Speakers performance readily available.
With Dennis and Rick (should include Jeff P), they have sent designs out to be vetted by third parties, too.
I'm not interested in bagging on any designer, regardless of where they live or how long they have been in the industry.
As an educated consumer, I am interested in proof of why I should give a person my business. Subjective claims carry no water. Whether I'm buying a power tool, a computer, a phone, or Audio Gear, I want to see the straight dope before I buy. If the company isn't willing to proved for that in any of their respective marketplaces, they are dead to me.
