Post Subject: Bass boxes updatesPosted by kodomo on: 1/6/2017
You may remember that my bass reflex boxes were sitting on top of the carpet. I installed a few days ago, 4 brass spikes under each one, then their foots to sit on, and put them on the sandwich granite bases I made. Bases are 50kg each now!
I have also covered the opposite walls of the drivers inside the box with rockwool and covered that with felt.
This had a very good overall effect on sound. I was very happy with everything over about 200hz in my system for sometime. Now, I am very happy down to 20hz. Do not get me wrong, it was sounding fine and was blending well. Now, I have spacious sound at the bass frequincies too and the sounds start and stop and die in the room more naturally. Overall it sounds like the system had just thrown another veil over its sound that was covering some of the bass. The denser passages sound even better now.
As of now, I have finished everything I planned to do with my system and I am very happy with the result. Further than this will be new adventures. One of these could be the rebuilding of the basshorn out of wood with the exact specs of the one I use now. Another one might be the trial of jmlc 270hz horn instead of the tractrix 200 as it wont pose much of a problem height wise. The acoustic center will be 5cm's higher, but the wood horn and the new frame will take the system 7 cm's lower. So I can do them together in the future. If it does not work as good as I want, I will have an extra 110hz horn, 270hz horn, 1000hz horn. Maybe I can get another tweeter and build a second similar pair as a test platform or sell it to fund other projects
