Long story short, I built speakers in the past, I have the tools and the knowledge, access to shops with CNC machines etc. Being short of time and not that willing to turn my house into a workshop as I once was, I want to try a pre-existing design and only take care of the building part. My goal is to satisfy my curiosity: is it possible to achieve the sound quality of commercial upper range booksleves with DIY? Important: I already own a commercial system which satisfies me, this is purely an experiment, but if it turns out sucessfully they could become my main speakers. I thought about Zaph's ZD5 but then found the negative review of his ZA5.2 speakers here on ASR and thought hold your horses gn77b. Or maybe something from Troels Gravesen? Or anything else. For some reason I've grown to dislike floorstanders but I'm willing to make a compromise if it's worth it. So I'm open to suggestions.
