Crossovers... (1 Viewer)

Legendary70 · Mar 26, 2015

Hi.
I have 2 TSI 400's, TSx center, 2 PSW 110's, 2 polk surrounds and 2 Onkyo rears. All running on a Sony str-dn1040. I need recommendations for the crossover on all my speakers. I have them all on small and I have the subs on 80, the fronts on 80, center on 80 or 100, and the the four surrounds on 80 i think. what should they be on?

Whatever sounds best, to you, to 5-10hz* higher than the -3 on your speakers.

*Like if a pair reaches 65 hz. Your choices are 60 and 80. Choose 80, cause it is your next higher choice.

You didn't give a model number for the surrounds and rears, but I'm going to guess that they should be higher, say 100.

Also, the sub shouldn't have a crossover set; either set it to "off" or "maximum".

I would rather set the x over on the sub to off and then let the AVR handle the x over for the sub. What does the auto setup tell you for the x over levels when you run it? That could be a good guide for you to at least start with. With towers you could probably set the fronts lower much than 80...I have seen small books that would do 80. I'm thinking you could do 70 or less across the front with no problems and probably less on the towers. The rears are anyone's guess without model numbers to reference.

The model of the surrounds is a polk TSi 100's. The rear Onkyos honestly I do not know. So the surrounds should be at around 100?

The subs are setup in the AVR in the LFE settings....they are set to 80. Another theatre forum said to put them on 120? What would be the difference if any having them on 80 or 120? thx. One of the subs is on phase 0 and the other on phase 160 ( think it is). I was told to have them set to opposite as far as phase is concerned. thx.

The 100's go down to 61, based on those (and ignoring the rears) I withdrawal my reco, leave it at 80.

You're already splitting the signal on the mains at [something, say 80], that tells the receiver to send everything* above 80 to the mains and everything below to the sub. So it's just not a good idea to set another filter for the sub, send it everything you're not sending to the mains. *And to compound the issue, it's not really a hard split at 80, its a slope defined by the receiver circuitry; that said ...

The subs are setup in the AVR in the LFE settings

I though you meant that you were setting the crossover on the sub; if you're using the receiver it should be smart enouhg to not screw up it's own signal processing.

ok. the model number for the surrounds are TSi 100's. The Onkyo rears I honestly do not know off hand.

I am setting the crossover for the speakers and the sub from the AVR. I have the subs at 80. I was told on another site to put them on 120. so i am a little confused on what I should put them on and why?

I initially did the audyssey set up when I first bought the AVR but I do not remember the settings it gave me. since then I have put the fronts on 80 and the levels at +8.0. center at 80 and level at +8.5. the surrounds at 80 and levels at +9.5. same for the rears. the subs are at 80 and level at +6.0. Ideas?

i was also told to try to put the fronts on 70. thx.

Sony doesn't use Audyssey. They have their own proprietary.

You only mess with sub phase...never. Leave them 0, unless for some reason you have them on the same wall...turned opposite each other.

thx anderson. so i should have the fronts more or less on 70 or 80? The center on 80? and the surrounds on 100? Yes I set the crossover for all the speakers through the AVR including the subs.

here is a pic of the subs location.....

So the TSi 100 -3 are listed at 61Hz so you should be able to cross them at 70 to 80 no problem. My Sony allows +\- 10 Hz increments vs the 20 on my Denon so 70 should work just fine.

I would keep the sub at 80 and not go to 120. Anything above 80 makes the sub more localized which if you can avoid you want to. That way the sub blends in with the other speakers as the lower bass is not as directional. With the speakers that you have listed you should not have issues keeping the x over set low so the sub can do what is was meant to do...produce low tones.

Sam is right Sony doesn't use Audyssey but they do have their own flavor so it might be worth it to run the auto setup again. This might help with your levels and distance numbers too. I'm not sure why your levels are all set to +6 or greater. You would think you would set the lowest levels to 0 and then only use a +4 or less for the others that differ from that.

If you can you should move one of the subs to the rear of the room cross corner from the current one for better blending if I remember correctly. RobertJ is the expert you should ask...he might chime in you never know.

thx arm. I will use those crossovers. Now I can tell you the Onkyos are actually bookshelf speakers. they came with a HTIB several years ago.

When it comes to levels.... I need some help. I have those levels high because i figured the higher the better....lolol. Newbie!!!!

Lamens.....pls.

Yes, two subs in different locations can smooth out the in-room response but this is the next step in calibration. You need Room EQ Wizard, a PC and a calibrated mic. At minimum, an analog Radio Shack SPL meter, test tones and MS Excel. That way you can get the best bass response at your seat.

I have never tried this because my room doesn't lend itself to moving subs around. I'm just using the brute force method with large, high excursion drivers and a lot of power.

k. let me see what i can do. thx.

That is why I have tower speakers....everywhere.
