I have a DIY sub using a JBL GTO 1014D.
It was well made, with internal bracing, a flat response and well adjusted port.
I was looking some Dynaudio and Revel subs that are sealed and I decided to try mine in that mode.
My sub is playing up to 40 Hz, and above that I have a pair of Revel M105 (since I only hear at low SPL, I preferred to use my sub just to extend the bass response).
First of all I measured my sub with the port open and I made it sealed using two T-Shirts closing the port . I got a sealed speaker with a Qtc = 0,6.
I measured again and adjusted the gain until I’ve got the same spl at low frequencies. Just to know, I needed to increase the sub level by 4dB in my receiver until the curve matches (both on them was measured from 20 Hz)
So, I’ve started hearing.
I found the sealed sub more “soft”, damped, well behaved. My impression was that I was hearing more notes.
The problem is my test was not blind and I’m afraid to be hearing differences just because I read about them in the past.
Does someone made a test like this? What you guys think?
