Do you think you need a subwoofer?

Here's the official statement from REL on their "crossover" (called that for convenience since it is technically not a crossover as it does not have a highpass):

"The crossover is not a fixed low pass, but rather a more complex sloping rolloff. If you set the rolloff to 30 Hz, for example, it will play everything 30 Hz and below with no intentional rolloff. It will also play above 30 Hz, rolled off at 12dB per octave, until 80 Hz, where it will continue to play, but with an even steeper rolloff. This allows the REL to integrate as seamlessly as possible with your main speakers."

Thus with a 25dB crossover at 100Hz the signal is down at least 24dB, probably much more. However, the only way to know for sure what is going on is to measure which we are hopefully all doing.

I think Doug would be surprised at the benefit from a single REL Stentor III crossed at 25Hz, but only by listening would he know for sure.

Hello Doug,

Adding the REL is a quick solution that most likely would result in a nice improvement without any chance of hurting your sound.

Ideally, you would want an external crossover so that each driver would get just what it needs but that is not an option for most of us. I personally would not want a sub with a full crossover to fed a speaker with a full crossover. One could still come out ahead but it would not ideal.

Anyhow, no end of things to try and people telling you to try them!
