Hello again!

There's another thing I want to ask you: I got an amplified subwoofer,
but the sound was too loud even at the start of the knob range.
Yesterday I put a resistance on the signal cable, and now the signal
got lower and I can use the full knob range to choose the right level.


Do you think that this resistance can in some way harm the main
amplifier or the sub amplifier? I tried for 5 minutes and the system
sounds great...

thanks again!

No problem, but this prompts a question. What are your main speakers?
Most subs will happily cover the normally expected range of
sensitivities, so yours must be very low.

Now a couple of celestion kr1, until I repair the old Canton of which
I wrote in the former thread.

Excuse me, I think I didn't get the point... (my English is BAD!)

thanks

The level control on the subwoofer is designed to make it match the
main speakers (your Celestions). The subwoofer control should have
enough adjustment to match the level of your speakers without needing
to add a resistor.

Because you needed a resistor, I assumed that you had speakers which
played at an unusually low volume, but I see now that they are KR1s,
which are in fact very sensitive (93dB from 1watt). So the resistor
makes no sense to me.

Are you the same person who is complaining about too much LF
in another question? Why would you add a subwoofer to a system
that has "too much energy on low frequencies"?

Subwoofers are more about low frequency extension than about low frequency
volume. IOW, subwoofers enable systems to cover a wider range of
frequncies and may therefore be warranted in systems that provide too
much energy at frequencies that they can reproduce without subwoofers.

yes, it seems strange, but it's me. I builded the SW some year ago,
when the speakers were still good. Since some months I'm compulsed to
keep it off (because of the LF issue), but last week I borrowed
another pair of speakers (the celestion kr1) and with these the SW
works fine. I always had the issue with the SW knob range, and I
thought I could fix it with a resistor I got from a broken walkman.

It's a complex world... :-))

The SW is not factory made, I builded it adding a (powerful!) class D
amp to an old acoustic SW. Some days ago I thought that I could fix
the knob range problem with a resistor on the signal cable (and it
worked), but I feared it could harm the amp.

The resistor works fine, now I can use the whole control range to find
the right level, before it started to sound too loud even at 1/4
knob...

thank you

If the resistor is on the input side of the sub, and it is an amplified sub
using line level input, there is no way that any harm can come.

Yes, it's that way. I was concerned that the resistor could damage the
main amplifier (from which the signal cable comes), but everyone here
told me it won't. And actually it doesn't! :-)

thank you
