So I've been listening to these speakers for the last week and doing some AB comparisons. I must say that they really exceed my expectations in every way! I was planning on sticking these out in the garage while I build my N3TLs, but i think they'll be staying in my main system for the time being.
Before I began this project I brought the unmodified insignias inside and plugged them in for a night. My girls reaction was a curled lip and a question.. "why does it sound.. so... bleehhh". Her reaction after the rebuild was hilarious. She literally stopped in her tracks (which doesn't happen.. ever) and just stood there; mouth agape.. she turned to me and smiled wide. "Wow, that's incredible! I can't believe how good they sound.. they sound better than the other ones!" And its true.. they do.
They obviously aren't the best speakers i've ever head, but they are enjoyable and leave little to be desired. The on and off axis response is similar, pacing around while listening is no problem. They do sound better a little further away though, near field is a little brash. Overall they are a little on the warm side tonally (but not too much). Treble is realistic and at times impressive; not world class, but enjoyable. Bass is tight.. real tight, the weight of the cabinet is noticeable. I made the cabinet a little too wide for the crossover, but there are no noticeable issues, bass is very clean, tight, and dynamic down to about 50hz. Midrange is clean and realistic as well. Imaging is pretty damn good. Movies and Music both sound awesome.
I'm really happy with these. I'm honestly surprised at how good they sound. They really hold their own.
