In the Thread: My new “New” listening room, 2024
Post Subject: Very, very interesting.Posted by Romy the Cat on: 5/16/2024
I spent many hours listening and experimenting, trying to change the signature of my mid-base channel. Everything that I'm trying suggest me that I am in at very right direction but I am still not server I would say freeze the system and do not touch anything. I know exactly what I'm trying to accomplish I'm in a way my objectives are slightly deviated from what I had above. That puffiness an upper bass is that I reported before was not an objective but a method. It was a method to achieve something that feel I can do without that mid base p puffiness. It is a completely different approach as in the case of the horn one way on another the 15-in driver was very much idling against the amplifier very output transformer was designed to work against 2.5R. that driver idling might be interesting itself but the driver was sitting inside of the back chamber. In my current case, the driver is suspended but significantly large volume of sealed box an impact of changing amplifier loading is completely different. It is unquestionally since dropping drivers impedance is superbly beneficial in my case, electrically and subjectively what I hear. However my objective right now changed, I can slow down my mid base by loading my amplifier harder and it is now produces a truly spectacular result about 4 15 in drivers I tried created the presentation of very fruitful direction but created also some alien harmonics. I have tried altec 515b, 515d, 416a and JBL 2215. I did not move all my drivers from Amy's house I have there more 15" Vitivaxes, 18 Sound and Altec 803 and I think JBL 2245 but I remember they were in bad shape. I think the compliment mine made base with another pair of Vitavoxes should do the trick but I cannot experiment with any another drivers as none of them I have more then a pair. I have six 15 Vitavoxe but they are 3 10/40 and 3 ak150, so they are different. From what I heard so far, and it is amazingly interesting I'll looking for now not truly slow my mid base, this will be done automatically but loading the Milq harder but rather making the mid-base never stop. It is almost as I want to increase its output by 2-3 db and drop high pass filter, making it deacaing at upper knee slower. I am almost there but I need this slow decay to be more connected harmonically with my rest of midrange. It is super excited time...
