Rel sub
Rel advises against using one sub with mono blocks. Any one tried it with success ?
Why is a single powered subwoofer getting involved with the mono amplifiers? I have a single powered sub and simply Connect the rca cable to the back of it. My sub has volume and crossover settings on the back. It's a b&w asw 2000. Newer subs require Wi-Fi access to adjust them which is troubling but it's the modern age I guess. I use the sub output from the processor I have. My main speakers when I use my preamp for two channel listening don't use a subwoofer. Not really needed. |
@fertguy One sub NEVER works well. You wind up with a disturbing modal pattern in almost any room, bass here, none there. Creating accurate bass below 60 Hz Also requires a lot of acoustic power which requires surface area (big drivers) and long excursions. Mono amps for the main speakers has nothing to do with it. The same situation results with a stereo amp. Read my Building Resonance Free Subwoofer thread below. The fact is you are better off with no subwoofer than a poorly implemented one. Aside from at least two subwoofers you also need a complete two way crossover. The low pass filter most subwoofers come with is inadequate. 1/2 the advantage of using a subwoofer is relieving the main speakers from having to produce low bass resulting in lower distortion levels. If cost is a factor you can always stage your subwoofer system. Subwoofers done right are the difference between a live performance and just another stereo. |

I'll take your word for it but I can't understand why just one sub could cause this: What does modal mean in music?
Modal music: what it is and how it works. Modal music is less sophisticated than tonal music, modal music is in fact based on a scale and uses the notes of that scale without any particular complications. Within a given scale (or mode) the notes are all the same, they have no particular roles.

Just get a second REL sub, I have monoblocks and researched the issue of a single sub, not good for REL subs or any subs for that matter. My present setup with the two REL subs provides me with most coherent low bass I've yet experienced. This vs. various single subs setups via low level outputs and DSP.
