Standby mode on ULS-15—why use it?

I have owned my four ULS-15 subs for at least five years and am still very pleased with their performance. Lately, I have noticed that one of the subs requires a stronger signal than the other three...

Whether or not rear surround speakers add significant value or not is purely subjective. I have a 7.1 configuration but am rarely aware of a significant contribution from the rear surrounds.

It is important to gain match your components. If you are a REW user, you can output a 50Hz sine wave to the sub channel at -3dBFS with the AVR MV set to unity and the sub channel trim to zero. ...

My ULS-15's are all gain-matched to 90dB output, which occurs at approximately the 9 O'clock position on the gain control, or about 25% gain. This is carefully calculated to result in a combined...

I use an unbalanced MiniDSP 2x4 as well. I take care that the input voltage doesn't exceed .9V, which on my AVR occurs at a trim of -4.5. So, with some trial-and-error, and by gain-matching my four...

Question Acceptable input voltage range for ULS-15?

Using a voltmeter, I can vary the subwoofer output channel trim on my AVR from .2VRMS to 5.1VRMS, with the trim at -12 and +12, respectively. This is while the AVR is outputting a 60Hz sine wave at...

If your priorities are music, and accuracy, choose the ULS-15. If you want volume, punch, and prefer movies, choose the VTF.

The gain controls on my ULS-15's are pretty sensitive as well. If the sub is working otherwise, I suspect this is normal.

The Onkyo PR-SC5509 has balanced outputs, Audyssey XT32 with Sub EQ HT. It is a pre-pro, so you will need five channels of amplification. Emotiva power amps have balanced inputs.
