The Great Big Audio Lie

Whatever you were told before about speakers is completely false. The new industry standard is defined in this video.

It's not a flex really, it's just very good choices

Yeah. His very basic speaker set up that he probably paid like 100 bucks for..........Because he still lives with his parents and he still needs help from daddy since he can't get a job

Thats whats insane in the audio hobby , people will spend 4k more for a miniscule difference, system synergy and room dampening is much more important than fancy cables and high dollar equipment

[@agony600]

Define system synergy

[@hugevibez]

@agony600 I mean, planars can sound awful on tube amplifiers. Though you are correct, that this is often overstated and mostly a scam told to get people to spend exorbitant amounts of money. You should mostly worry about room reflections and good speakers before worrying about things like amplifiers and especially dacs. Of course there is a minimum level you should reach in that these elements aren't introducing any noise, but that can be had for very low prices.

[@LynnXternal]

4:30 "larger driver doesn't move as fast" This is not correct. The acoustic output of a driver is dependent on its acceleration. You can work this out using simple newotonian mechanics: pressure = force / area; force = mass * acceleration; acceleration = second derivative of displacement. A large driver is not good at high frequencies because of cone breakups. The pistonic motion of the driver is severely compromised due to these breakups, and the resulting modal analysis will show you that those breakup modes will acoustically short circuit (essentially you have an array of dipoles rather than an ideal diaphragm following simple plate theory). Larger/multiple voicecoils and stiffer diaphragm materials can mitigate the problem, but a larger driver will also start to beamform at high frequencies. PA systems often use midrange (yes, midrange, as in playing at least up to 1 kHz) drive units that can be 10", 12", or even 15" or larger. It all boils down to the design parameters.

[@LynnXternal]

A bigger driver is more efficient than a smaller driver because of its hydrodynamic output (as opposed to acoustic output). It more easily moves a larger mass of air in the nearfield, which is where the majority of the system's energy is dissipated

This is further evidence in favor of tower speakers.

A tiny monitor crossed over to a big subwoofer for bass is more powerful than any tower speaker.

@@sebastianbaran9645 it's likely fine, but not necessarily optimal. The bass won't be as enveloping as that from a subwoofer

how about a sub with towers lol.

[@agony600]

W371A is *not* a subwoofer, it’s a woofer and is designed to provide greater output when combined with the ones and controlled dispersion down to around 63Hz. This, combined with carefully managed multiple subwoofers should essentially combat all major issues with the room i.e modes and SBIR.

Some time ago you said that stereo sub is not a thing when I pointed that out. I'm glad you changed idea. ❤

[@sharuraudio]

i mean, the subs playing in stereo vs mono still barely matters, but it matters more for higher crossover

[@niccster1061]

I agree with a good chunk of what u r saying but just a reminder 1. You arent the only person who knows what they are talking about 2. You havent heard what you havent heard. Still respect the effort

[@justino9042]

do you think with one subwoofer could be enough tho to not expend that much money?

[@sharuraudio]

yesh

[@hugevibez]

I mean you set the crossover usually at 70-80hz to make the sub disappear, at higher frequencies directionality comes in to play. You're not entirely wrong on driver size, the SPL you get from smaller drivers is just not enough to properly serve the sub bass regio. A lot of sub-bass immersion comes from physically feeling vibrations, rather than hearing them (especially sub 20 which we can't hear at all). This is where headphones fail because you don't feel the vibrations through your body, even if the frequency response is there. Wearable subwoofers exist to achieve this without upsetting the entire neighborhood. Though time-aligning such a huge driver through it's entire frequency response to a much smaller driver is no easy feat. You can do a lot with DSP, but the better solution would be to have 2 smaller subwoofers for bass-extension for your bookshelves, and a single larger driver with enough SPL to fill your room for the lower sub-bass region, since directionality doesn't matter at this frequency. You can add more subs for bass management to improve things further, since with sub bass the difference in oscilations at different frequencies can be quite large. You could also go for towers without bass extension subwoofers, but with towers you again have more directional awareness and thus not as good of a performance with imaging and again more drivers that can be misaligned, with potentially no way to fix it if it only has a single input and no crossover bypass. You are near-field, so these issues come less in to play. It's important to understand no universal solutions exist when it comes to types of speakers, placement, bass management, etc. It all depends on your room. With that in mind, Neumann headphones are aimed at the studio and not the home, so they are purely analytical tools. Bass immersion is not what is the goal here, rather to make sure there aren't any nasty sounds hidden in those lower regions for when the song is played back at a soundsystem that does support these frequencies.

[@sharuraudio]

70 Hz crossover is trash. Just have the subwoofers positioned for stereo

[@TantrumAudio]

It's all about the trade off between two things. SPL and extension.

[@thisrocks]

Just earlier today I finally got my 2 subs (SVS SB-2000) to complete my setup (got KH 120 ii and miniDSP flex a couple of months ago) and really want a tutorial on how to time and volume align + EQ everything. If there's anything you can offer to help I would greatly appreciate it.

[@fulltimeweaboo]

I got the kh150s because bigger number better number bigger better and lastly better bigger number but mostly it’s just me not wanting to get another two subs as I already have an elac I can’t get rid of and I don’t want another similar sub because it only goes down to 30hz 😢 it’s hard to sell off hifi in the third world

[@RJ-xj3ct]

I also think the cost of these "audiophile subs" like the Genelec and whatnot are complete waste of $$$ Brands like Perlisten, new SVS 17 series, PSA, HSU make phenomenal subs for the money and they measure extremely well too.
