The OBL-11 is playing promising. My experience is that they need long
burn in time. They were terrible the first 20 hours, now after
approximately 200 hours they really start coming alive. I love the
feeling of live music, the tone and dynamics is excellent. The
amplifiers I use is a bi-amp set up by us of two Audio Note Kit2
(2*18watt single ended KT88 per speaker). I have a 20m2 HI-FI room.
For the moment I play a lot of trash metal and even black metal, and
the speaker’s rock like hell. This is the best speaker I have had in
my HI-FI room. I also listen to the AN/E Kit 3 and Klipsch RF5 on my
The OBL-11 speakers really play the tone of the recordings and no boxy
sound is present. I put on Dire Straits (sultans of swing) and Eagels
(hell freezes over) only to break from metal and it playing excellent.
Even classic music plays nice.
My stereo is upgraded and tweaked to perfection, only the “best”
components are used, and this appears by the sound of the speakers.
I am also locking into some push pull mono blocks amplifiers to really
kick the metal out of the speakers. I can come back to this project
later, and review two well burned in OBL-11 speakers.
An OBL-11 update:
Refer to OBL-11, built by Olav, Norway
All the components have now burn in nicely
and the speakers have really come to life, in a high-quality way.
I have now built some ANK push pull 40w mono
blocks for the OBL-11 speakers and using two “road brick” per speaker.
This was an impressive upgrade. The speaker can play dangerous load,
110dB without distortion is no problem. Wow, this is cool.
