Rel sub
Rel advises against using one sub with mono blocks. Any one tried it with success ?
I'm pretty sure Rel recommends using two sub woofers if at all possible They both eliminate so many room issues especially with a two channel stereo system I have two subs along with my tower speakers that have built-in powered sub woofers There is a really good series on YouTube called " Subwoofer 101" and it covers all aspects of sub woofer setup and he swears by having two sub woofers |
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.
