1. Use only one set of crossovers. Usually, one uses the ones in the receiver and that means turning the sub's crossovers off.

2. The actually settings depend on the speakers and the setup but start with all of them set about 10Hz above your B&W's low frequency cutoff. That is, if the B&Ws are rated to 70Hz, set all the crossovers to 80Hz.

3. Once you have used that setting and know what it sounds like, feel free to adjust each to ear for the smoothest, most integrated sound.

By turning off the subwoofer`s lowpass and highpass crossover, do you mean to turn each respective knob to 0 (zero). I dont believe these options are on vs off, but rather 0 to 220HZ, or something like that.


I will try go into the receiver and try 80HZ for the subwoofer crossover and put 80HZ for the front receiver. I will then turn the subwoofer`s low crossover to zero and its high crossover to zero.



Thanks

BIG CORRECTION: Turn the LP as high as possible, to 220Hz and the HP as low as possible. That will mean they will have minimal effect on the system as your real crossovers will be far away.

(Unless 0=off which you can only determine from your manual. Otherwise, 0 makes no sense.)


Sorry for the slip of the mind.


Kal

 

Thanks for the info!!!!!!


I reexamined my subwoofer and have the following options -


1. Lowpass crossover - 40 to 120 HZ

2. High pass crossover - 100 vs 80 HZ (only two options)

3. I must choose one of the following INTERNAL CROSSOVER or DIRECT

4. Phase - 0 or 180.


In my receiver I chose 80hZ for crossover for the front speakers and 80HZ for the crossover for the subwoofer.


So, on my sub, what do you suggest? If I understand your post, I should choose

the following -


On sub -

Lowpass crossover 120HZ

high pass crossover 80hz

Internal vs Direct??? Which do I select?

Phase- 0 or 180? My sub is close to front speakers, so I chose 0. Correct?


I am glad you are helping me with this. I have read the manuals but nothing is very clear. I have invested a lot of money in my system and I think it is a shame if I have the wrong configuration, which I bet is pretty common with HT gear.

Thanks again.

Fine.

Choose DIRECT. It will bypass all the subs settings and let the AVR do its job correctly. Phase? 0 is a good start but you should try it both ways.

For phase, typically people say "pick the one that you obtain the fullest bass".


Otherwise, it seems like you have great advice from Mr. Rubinson.



If you have B&W 602s3 (large bookshelf), you might be able to have a better experience with the 60hz crossover on the receiver. Of course, this depends on your size room, and your ears.

I am glad to see someone with some credibility recommending this. I own a Monitor Audio GR10 system, and they have a low freq cutoff at 40 + or - 3dB. I really like the way they sound at 60hz crossover, but always feel guilty that they are not crossed over at 80hz, which seems to be the overwhelming recommendation (2x the low frequency crossover). Thanks Kal

Its pretty easy to see if you have err'd in your selection of crossover. Simply run some 40hz-100hz sine waves and take note of the crossover region. Many times, the room will add 10hz to the bass -3db point. If you have your speakers close to a wall or corner, the response could be even more skewed. That's why its not always good to use a "rule" in conjunction with specs.

Sure. To quote myself:

Right, i wasnt doubting your words. I was simply giving an example of how to tune the system to the room as best as possible.

 

Thxs Jono and Kal for your replies!

I do have B&W 602s3 large bookshelves as front speakers. My surrounds are dipole B&W.


I will try your suggestion of 60hz for crossover in my receiver. Thanks again for your help! Like many, I am always trying to get the best out of my system and proper configuration is important.

Kal - I had a question. I'm trying to find out what the low frequency cut off of my Klipsh R-B5 bookshelves would be. The closest I could find on the Klipsch website was this:


FREQUENCY RESPONSE:

48Hz-20kHz±3dB


Does that mean Klipsch rates my speakers as 48Hz, or am I reading that wrong?

Seems reasonable in the absence of a good frequency-response curve and assuming you trust the manufacturer.

If you have a Radio Shack SPL meter (or are able to purchase one for 45$), you will be able to see what your room frequency response is. 48hz might be the rating for anechoic chamber.


For example, in my room, my 49hz rated speakers are -3db at 38hz. If you are just using the receiver's high pass and low pass filters, then it doesn't really matter where you set the crossover (50hz-60hz). If you do not have bass management, then the subwoofer's crossover would have to be set lower around 30-35hz to prevent too much bass overlap.


In the end, the best way to ensure decent integration of subwoofer to the system is to measure the response somehow (RS SPL Meter or better) so that you know that you have not caused a hole or bump in the frequency response.

 

Hi forum members,


New member here. I have cut and pasted this from a forum I belong to in Melbourne, Australia and was hoping that someone may be able to help me with my set up.




So in my situation where I have a Denon AVR-2807 receiver, B & W 603 S3 mains, B & W 601 S3 rears and an LCR600 S3 centre, I would set the fronts and rears to small, now that I purchased a new sub today being a Velodyne CHT-12R??? Even though the fronts are floor standers??



Whilst on the calibration topic, I may eventually get an SPL but for now my receiver is a Denon AVR-2807 and I use the auto set-up. With this do I still need to set speaker distances or does the mic (set in the listening position) do that for you???



Further to this, with regards to the Velodyne working in conjunction with the Denon amp what settings on the receiver would I need to set the fronts and rears to?? I have heard 80hZ (default is 40hZ), the centre is defaulted at 200hZ ( have left that ) and the LFE (sub) is set to 80hZ.


On my sub I have "direct" activated, the high pass crossover is set to 80hZ (two options - 80 and 100hZ), how about the low pass????? And phasing?? Although I believe the phasing is a matter of preference and room set up.



Any assistance to this would be greatly appreciated. Am looking at getting an SPL soon so further fine tune my system but for now any assistance would be most welcome.



Kind regards.

Correct.

Auto setup does it for you.

All speakers set to small, all speakers crossed over at 80Hz and LFE crossover at 120Hz. Correct to these settings after running auto EQ.

I am not familiar with your sub, but what you want is to take the sub settings out of the picture and let the receiver handle as much of the bass management as possible. If you can not defeat the crossover on the sub, set it as high as possible.


Nick

 

Thanks Nick...


Yes was surprised that the default setting for the centre channel was 200hZ. The fronts and rears were defaulted to 40hZ.


As suggested I will reset the settings to those nominated and set-up the amp again using auto set-up.


Cheers and thanks for your help.

Bear in mind, each time you run auto setup, you will need to go in and correct the crossover settings and speaker sizes again. Here is a link to a thread on Aydyssey Auto EQ. Chris from Audyssey posted a FAQ at post 145.

Where can I download these sine waves?


And how do you determine proper crossover using them? I am juggling between a 60hz and 80hz crossover at the moment. If the SPL drops significantly with a 60hz crossover, then that means I should stick with 80hz?
