This is kind of funny. I got another B2 amp a few days back. It was near new condition, at least inside. As I plug it to drive my ULF I felt that it produces some kind of strange bass. I did not like it at all and it was very different then what I got from my broken B2. I looked at the scope what my second B2 does with 5V input signal. I had some odd distortions. Sucks, the amp need to send to fix it….

I pull from basement another cheap consumer amp. I did test it on a bench and it was working very fine, clipping with 10.6V and running flat down to 12Hz. I figured out it will be fine as a temp solution and I put it in the system. It worked fine but the character of ULF was not even closed to B2 and very far from where I would like it to be.

What however took my interest was that this new consumer amp, along with B2 had very precise meters and they do not run even at ¼ of the full power at the new amp. On B2 they did not run even at 1/6 of full power. The new amp it 50W SS Hitachi or something like this. So, I asked myself how much power do I need for my ULF?

The question is very much important. I am under presumption that I need over 100W, preferably more to drive my LILF line arrays. Back in the Milq forum I have couple threads dedicated to an idea how to get a lot of power from LF DSET:

Still, if in reality I need only 20-30W then I am very much in the realm of paralleled 6C33C that would be very easy to do. I reality I do not know how much power I need in my new room.

In my old room I knew that my Milq LF run securely in A1 but then room was much smaller my woofer array were larger.

I need to do the same test with my new room. Frankly I feel that if wood be able to beef up my woofer towers with 8 drivers per channel and to use a dual 6C33C out then I will be able to make a phenomenal ULF  DSET. I just need to evaluate how much power I would need and would 35W-40W that I can get from a pair of 6C33C enough.
