I never said that I felt that I was wasting my time by commenting and indeed I do not feel that way.I never said that Alex-Z was incorrect - far be it for me to make that claim. I believe I've been quite clear in my replies. And my beef with him is one of attitude, not expertise.
I never said these speakers were a "diamond in the rough". In fact, I accept the technically detailed and substantiated evaluation presented in the other thread. Did you read that?
I never said I had decided on rockwool to line the cabinets. In fact, the general consensus within the speaker-building community is to line ported cabinets. This is an acoustic suspension-style speaker. I have since decided to stuff them with Acoustica-Fil.
I've also decided to replace the mid with a slightly better, yet reasonably-priced one that matches the selected crossover, since the woofer is doing most of the midrange work in Yamaha's cheap capacitor-only solution.
Why am I wasting my time on this project? Because I have more time than money, being retired after 30+ years in electronics/electromechanical repair, training, and support, as well as 10 years with the US Department of Defense. In my "beginner" opinion, it's worth $100 or so to try and improve these speakers, rather than just throw up my hands and say "there's nothing I can do" or buy another pair, and relegate these to storage space I don't have. AGAIN, if they're the worst speakers ever as y'all claim (they're not), then they can only get better, even if it's just a little.
So I will consider your comments, but I'll make my own decisions based on criteria other than purely technical. But why are you wasting YOUR valuable time and expertise commenting?
I love DIY and I'd love to hear you had fun messing around.
Like I said you start where you start and thus everyone starts at their own beginning.
I just felt it was disingenuous and unwarranted to try reprimand @alex-z , his comments were well informed and not over any sort etiquette line that I can see. Maybe he was saying what you did not want to hear but this is an open forum on a highly technical website so it stand to reason that some posters will be pointing out what a big job fixing these speakers to a high technical standard would be. Now "f"ing around with it all and having fun is not dependent on the final product being technically good.
Have a blast and line those cabinets with the 3-layer stuff I linked. You might actually be shocked at how much that stuff deadens live cabs. The pollyfill wont do anything for cab resonances. That not what it is for.
Anyway have a ton of fun and take care in your retirement.
