It is likely going to be way worse boosted, so let it be a smooth degradation ever so slightly lower. Ultra Low Subwoofer Test Tone Frequency Generator. The worst thing you can do is go by ear and boost the bass because you think it will be flatter. Go by ear, and for your sub you should probably set the volume so it appears to drop off in volume. In a room with reflections they will be all sorts of way off. they are generally used as a rough way to determine the listening level and make sure you won't go deaf quickly or in anechoic environments to measure absolute volume. Call it good, stop fiddling, listen, and revisit the issue when you get some treatment.Įdit- those radioshack testers don't work well, its hard to aim them properly. below 30 and its the feeling, not the sound.īe happy it sounds pretty flat, there are usually tons of dips and whatnot without treatment.
The tone generator can play four different waveforms: Sine, Square, Sawtooth and Triangle. The tone will continue until the stop button is pushed. You will hear a pure tone sine wave sampled at a rate of 44.1kHz. Don't expect to hear much below 30 anyway, theres so much energy lost in the room without treatment (or if it has a loud computer in it, etc.) that its really shouldn't be a big deal unless you listen to your music like those people with crazy subs in their cars and just listen to the rattling of the car around it. Simply enter your desired frequency and press play. You are correct in raising the sub xover, the mmgs clearly roll off quickly. Has anyone ever tried using a tone generator to set their sub crossovers? I made sure that the volume was fairly low so I wouldn't fry the speakers, it was set at about -20db. So I'm not really getting much frequency response below 35hz. Unfortunately, although the Outlaws are advertised as going down to 30hz, the volume starts dropping off around 35hz and by 32hz the response is almost nill. There are a couple of tones that seem to reverberate more than others but that can most likely be corrected with room treatments. I have a Radio Shack sound pressure meter that I plan to break out and test the actual decibels, but by ear it sounds pretty consistent. So after changing the crossover frequency and adjusting the volume, I now have a fairly consistent volume from 35hz up through 150hz and beyond. This led to the conclusion/discovery that my MMGs aren't really kicking in until around 56hz. When I first ran a slow sweep from 30hz to 80hz, I noticed a big drop-out around 50 - 55hz, mainly due to the fact that my sub crossover freq was set at 50hz, per Magnepan's suggestion.
I downloaded a tone generator to my PC and I discovered that I could use it to help nail down the sub-woofer settings. I've been having trouble getting the subs' crossover frequency and volume set properly. I have Magnepan's MMG speakers, and also a pair of Outlaw subs. I use my PC and an outboard DAC - Motu 828mk3 - to listen to CDs.
