PSI Audio A214-M Studio Red

I use 2 units as stereo system speakers, though I know it is designed as central speaker. But think about PSI A215. I guess A214 is the same in electronic aspect as A215. Stereo A214 brings a clear and transparent sound image, very precise at stage performance, like unveiling everything hiden in the waves. Due to D'Appolito design, also known as MTM structure. It performs like a coxial speaker but actually less phase distortion and interference than physical coxial structure.
If there is anything I am not very satisfied, it must be the woofer. It's too small, I insist. More than 6.5" would be better. Or I can expect that PSI would come out a new model, A217, merging 2 units A17 indeed.
