2009年1月24日 · But keep in mind, the even at -6db, the actual sound you hear hasn't fallen that much. So, either -3db or -6db, represents the full functional range of the speakers. Below the low frequency, the sound doesn't just stop, it continues to fade until the …

2025年1月9日 · There's a number of things that make this not quite true, impedance of the speaker will affect the output, your losses and gains won't be exactly 6dB as you move away from the speaker, or you double the input power. But that should be close enough to explain why a 50w amp can do as well as a more powerful amp - purely in terms of power in -> SPL.

2008年2月14日 · The FAT -6DB Attenuators does exactly what it says attenuates by 6 dB. This will be needed to give you the correct signal level at the back of your STB. Too much or too little signal and you will get problems. The Isolator should be the 1st component as it enters your premises, the attenuator can be connected to the back of your STB. Hope this ...

2014年8月28日 · the speed of the rolloff & the magnitude of the phase shift increases as the order of the rolloff increases (1st order = 6dB/octave, 2nd = 12dB/octave, 3rd = 18dB/octave and so on) so the higher order rolloff switches output from sub to mains more quickly (in a shorter frequency range) than a lower order rolloff

2013年2月21日 · -3dB is essentially Flat Frequency response. -3dB is just the slightest noticeable change in volume. -6dB is a slightly more noticeable change in volume but still represent the proper working range of speaker.-6dB is NOT half the volume. It is two slightly noticeable changes down ward in the volume.

2023年8月18日 · Btw, I like around + 6db of bass shelf. But as @Paul7777x mentioned, this is a matter of personal taste and is just adjusted accordingly. KEF R3 Meta + Powernode N330

2020年5月14日 · So had a quick look at the settings on my Sony Strdn1080 and the sub setting is at - 6db is this normal the settings on the back of the sub are crossover max and volume at about 11 oclock thanks

2015年5月31日 · I add around 6db 70-10hz dropping to 2-3 by 5Hz Cinema - Carada masked 134",Modded UB 9000 & Lumagen 4242, Epson LS10500, Naim 32.5 x 4,Supercap, 135x9, Sonus Faber Extrema, Cremona, Elipsa, Amator, 3xCremona subs,2x18"+amps,10x10HD

2024年12月9日 · Minx X300 is 6db down at 33Hz and due to passive radiator design this acts similar to ported sub so it will drop like a rock, but in this case the drop will be from much higher. It`s going to be struggling below 40Hz when pushed where as typically you would want strong clean output down to 20Hz.

2015年11月30日 · What exactly does it do - you can 'fine-tune' between -6db to +6db - how is this any different to setting the level normally? Is it there just to add/reduce bass to taste? Yamaha's marketing of it claims that it helps give a better image to the front speakers drawing the bass away from being perceived to be from the subwoofer.
