Crossover Setup

csnoff

Ok so after doing a lot of reading, I am still very confused about this. People have different opinions and I understand that audio is very subjective and how it sounds can be very different from one person to the next. So I have a question. Well first of I am running

Yamaha HTR 6190
Monitor 70 fronts
Klipsch RC 52 (soon to change to the CS2)
FXiA 4 Rear Surrounds
M20 Surrounds
PSW10 Sub

Ok so the Monitor 70
Overall Frequency Response 30Hz - 25kHz
Lower -3dB Limit 40Hz
Upper -3dB Limit 24kHz

My receiver is able to get down to 40Hz I think that is when I put them as small speakers, I have not checked what it would be if they were set to large.

So my question is this. What do I set the crossover on the sub to (all the way up to and then set the receiver crossover down to the lowest then adjust the volume on the sub??

How should I go about doing this.

Most people have said set the receiver to 80Hz and the sub all the way up but then you lose sound space or something along those lines. Help would be greatly appreciated.

From the PSW10 User Manual:

PSW10—
NOTE: The PSW10 subwoofer does not have an LFE input. Instead, use either the L or R Line input (another hookup option is to use a Y-split cable and connect both L and R Line inputs). After you make this Sub Out connection, turn the "Low Pass" filter fully clockwise. This will in effect create an LFE input.

You should start with the basic recommended configuration for your setup and then from there you can experiment to see what works best for you.

* Connect the PSW10 per the user manual from your AVR to the L/R inputs.
* Turn the Low Pass control on the back of the PSW10 full clockwise.
* Turn the PSW10 volume control to between 10-12 o'clock
* Re-run your AVR auto calibration routine.
* Check to see what settings the AVR set for your speakers - you'll find that it will have probably set all of your speakers to "Large". Set them to "Small"
* Set the AVR xover frequency to 80Hz.

Sit and enjoy for a bit - then you can experiment with the AVR xover frequency to see if you like a different setting better.

Thanks for the reply. Basically that is what I have been reading from alot of people but there have been the odd few that say otherwise, and that by setting it this way you end up with wasted sound space???

Is there a benefit to having the fronts set to large or small??

The argument goes as such:
For Home Theater use there is the potential for very deep and powerful "Low Frequency Effects" that your front speakers cannot reproduce accurately and that will put undo strain on your amp to provide power for.

So, by setting your speakers to small and the xover frequency on your AVR to 80Hz you 'offload' the LFE to the sub.

If all you have for a sub is the PSW10, I'd set them to large. @ 50w RMS, yor PSW10 is going to struggle taking all of the bass at a higher volume. Your Monitor 70s with a good amplifier (external, not your receiver) behind them and no PSW10 would probably supply a better amount of good clean bass. If you want the load off of your speakers completely, I'd look into a PSW505. They can be had for cheap these days. You should be able to recoup some cost by selling the PSW10 on Craigslist. I'm not necessarily a bass head, but I think you'll be happier with the vast amount of headroom and depth that a '505 has over a '10.
