SET MY SUB TO WHAT? | CROSSOVERS - A Break Down | @Aperion Audio | DISCUSSION

[@pastaman6099]

I found that for my Yamaha TSR 7850 the fronts are the ONLY ones that don't cut off the subwoofers when set to large, which is quite strange. Still, for movies I prefer them set to 80 hz even though they're towers. Music tho.. I REALLY love how it sounds when they're set to large! They only go down to 45 hz but still, my music listening levels are moderate at best, so no power issues here!

[@ben23a31]

Another work around regardless of speaker size is too connect your sub/s to the receiver front prehours. This way you can manually set the crossover (which I think is better) at the sub level. With multiple subs a single male to 2 female splitter does the trick. But again, the hobby is all about experimenting and having fun.

[@TylerStout]

Hmmm I'm trying to understand what setting AVR to 80hz and subwoofer plate amp to 60hz would accomplish. My guess is either the subwoofer's built in crossover has a different slope (I believe most AVRs are a 24db/octave LPF and 12db/octave HPF) or by changing the LPF your effecting the phase fixing some issues indirectly. Personally I didn't choose my crossover, it chose me. I used REW's time alignment tool to find the correct delay (ie distance/phase) and with specific crossovers and chose the one that had the best output before diminishing returns which happened to be 90hz over 80hz for my 5" bookshelf with a f3 of 57hz. I have an imgur link showing before/after but I don't know if YT allows external links.

As an owner of Def Tech ST towers, I HIGHLY recommend them. Very good bass that is able to fill the room with just the towers. Add another sub and run all 3 together, you got yourself some loud explosions and good bass. Also, they don't take up much floor space, so great for if you have a smaller room and don't have floor space for multiple subs.

[@elmerbais]

Still didnt get the answer that Ealan asked the first time. I think his question was “ how do you crossover the sub with different crossover of the speakers.”? Correct me if im wrong.

[@hometheaterjoe9489]

Love this interview, great video!! I need to see the whole thing!!

[@kadiummusic]

If you can get hold of a frequency graph of your woofers/tops and see where the bottom end starts to drop. Then gradually bring up the crossover point on your sub from just below that drop off until the transition between tops and sub sounds smooth. Adjust volume to taste. 😎

[@PerfectorZY]

This was wonderful!

[@frankeezee]

This is a topic that I thought I had covered. Yet, I was able to learn a few new things on this video.

[@ealanosborne]

Yay! Me too. Happy to have conversations like this, since it’s never a bad thing to learn more about something! 🙌

[@ShaileshPatel-le8cq]

If all 5 speakers have different frequencies. As all r Bookshelf speakers. I do not adjust each speaker's wise frequency than how to calculate C.O. frequency.

[@jasonwatkins4277]

Great video....now I have to go back and change all my settings!! :)

[@ealanosborne]

Such is home theater! 😄

[@thecarrotmonster8827]

I watched an Audioholics video and the dude said THX chose 80hz because it was also the best frequency to stop any localisation

[@wisdomb4086]

Wydm localisation

[@Noldy34]

Will you do a walk through video regarding the line/LFE crossover hookup being discussed here?

[@ealanosborne]

Good idea! 🙌

[@2KRICHKID]

I have a question! When I increase speakers level on my reciver. Does plus means increased volume and - means decrease volume?

[@ealanosborne]

That is correct.

[@felixlaboy1453]

Hi guys. Great info. I have a room that’s 12 X 26. Can you guys recommend a subwoofer. I would like to eventually get two.

[@ealanosborne]

Well, Aperion themselves have the Bravus 12D that could pressurize that size of a room fairly well. Although yes, 2 of them would fair better in the long term. 🤘

Hey in denon 1600h as they said there s small r large in settings! N where is the crossover frequency setting! And by seeing this i need to set 80hz as default in surround LCR and wht ll b the frequency for sub woofer!!? And if the surround is louder than LcR i need to increase the frequency of the surround is it so!?

[@ealanosborne]

No matter the size of the speaker, set it to “small” in the receiver, since that activates the crossover setting. 80 Hz is good for your bed layer speakers as well as your sub, but like they were saying, maybe try setting the sub’s crossover to 60 Hz and see how that sounds. The Aperion A5 height speakers, for example, only go down to 120 Hz, so setting its crossover to 80 Hz is silly, since it can’t reproduce sound that low. So set it to 140 or 150 Hz, whatever your receiver will allow. It all depends on the speakers’ rated frequency response and how it sounds to you in the end.

[@gowthamk5392]

@@ealanosborne hey what is the phase turner in the sub war? Like 0, 90, 270 like that..?

[@ealanosborne]

@@gowthamk5392 That Just has to do with time alignment between your other speakers and another sub, if you have more than one. If you have a calibration mic and REW, then turning the knob would help align the graphs better if they happen to be way off from the start. But then again, you might not even need to mess with it, since software like Audyssey will account for time alignment, and will apply delay to all speakers so that they hit the main listening position at the same time. 👍

@@ealanosborne oh cool! Thnk u

[@Dooguy]

so what about the arguement that with the deftech 8020's that have hard wire and LFE rca jacks......that you should turn off your LFE plus main and just use LFE so your subs do all the work. ? Some say leave the lfe plusmain on so u can take advantage of the 8020 self powered bass speakers in them.

[@ealanosborne]

Yeah, usually doing LFE+Main is more for movie/music hybrid purposes, so that the subs kick in even when the system pairs down to a 2-channel stereo PCM source. 🤘

[@Foreverjazzfan]

I have a couple questions. First, my center channel can only go down to 89 HZ. Is there a reason I’d set the crossover to 80 on that speaker or should I just set it to 90? Then my marantz avr wont allow me to set my sub crossover below 80. I can set it on the subs to 60 but the avr is going to set it at 80. What should I set the avr to on the subs?

[@ealanosborne]

Hmmm…well typically you want to set your crossover to 10-20 Hz above the lowest frequency it can handle. Since your center channel is rated to only go down to 89 Hz, you might want to try to set your sub’s crossover to 120 Hz, which is typical for an LFE channel. I’d try that first, then make any adjustments as needed.

[@terrata1]

Hi what would you recommend the crossover for a 2.1 stereo music only set up, my speakers frequency response is 40Hz - 20Khz My sub is a SVS sb1000 Thanks

[@ealanosborne]

Hi! If it's possible, I'd try and go for a crossover of 50-60 Hz, since it's best to set the crossover about 10-20 Hz higher than the lowest number your speakers can handle.

[@terrata1]

@@ealanosborne Thanks for the reply 👍

[@Sc2God724]

Seen this comment svs has a subwoofer tool that will tell you what to set your speakers crossover if they haven't tested it

[@hawkmoon369]

i have focal sopra 2 with dual rel ss12 so whats the best crossover for these speakers, on paper

[@ealanosborne]

On paper it says they can handle down to 34 Hz, so I’d say a crossover somewhere around 50 Hz should be good. 👍

[@hawkmoon369]

@Ealan Osborne just another question do you need the crossover frequency on dual subs set at the same frequency or can I set different on each sub? For 2 channel listening.

[@ealanosborne]

@@hawkmoon369 Oh you can set them to whatever is best for your room. Especially if you have 2 different subs. But even if they’re identical subs, one might need a slightly different crossover with its position in the room and how close it is to furniture or a wall, etc. 👍

[@hawkmoon369]

@Ealan Osborne excellent thanks I have 2 rel S812 only setting them up.

[@ealanosborne]

@@hawkmoon369 Hmmm…you might want to set that crossover a tad higher, since it has more room to travel 🤷‍♂️ Something to experiment with, since every room is different

[@lauriecabbage29]

I have an OLDER Denon (AVR-487) I have Old Fisher 15 inch BIG box speakers ...for a year, I tried everything to get more Sub bass...Then....Aaaahhhhh....I set my Receiver to LFE plus Main...all speakers set to small...and even though you'll say: Hes probly just a kid with some Junk...this System will rival anybodys stuff...My surrounds are AR

[@tristandesade8635]

THX is 80Hz not to protect components, but because it is two standard deviations below localizable frequencies. However, even that is theory, where subs have steep rolloff and low harmonic distortions. In reality a trained ear can easily localize sub even at 80Hz.🤓

[@khurrammalik5865]

If I set front channel as Big My brand new Yamaha RX-A6A Aventage does not send signal to the Sub and sounds terrible if I set it to surround Auto mode once I have selected the front channel as small problem solved and Subwoofer turns on 👍👍👍
