Hey Guys....
Yesterday the basic setup for 8" Bookshelfs is done, and they started singing. Driver and Tweeter are from Iwai. I hardly listened 30 min...and they sounded nice
. Too early to judge any way....
As of now, nothing is done on internal bracing, damping, and external paint finish.
I want to take time and understand how bracing and damping changes SQ.
I really doubt if I am critical enough to catch any minor changes in Sq.
I'm thinking if I should run them atleast 50-100 hours to make sure driver break-in happens. After that if I add bracing and then damping, I may have clarity if the SQ improvement is due to driver break-in or damping etc.
Secondly, Vent air velocity for this box is nearly 18m/sec. Unfortunately the box is cut and made based on my simulations in early stage of learning. Now I could bring the vent air velocity far down below 18m/sec....But the box is already made. I was a bit worried about port noice. But luckily I couldn't hear it as of now....

Il take time on making this better, and keep posted. I really need some measuring equipment now.
Regards,
Naveen
