Calibration needed? Small vs Large auto-set up questions

[Timothy E Smith]

I have just completed all the components of my apartment based 5.1 HT featuring Klipsch Fronts, center, R12 SW sub and SS-.5 surrounds driven by a Sony DH550 AVR for 5.2 set ups.

My question is that I have identified the RB61ii Front Left and Right as well as the RC-52 center as 'LARGE' in the speaker settings menu based on NO Prior knowledge of what constitutes a LARGE vs SMALL Speaker. Since with the DH550 this affects what is sent to Front Left, Center and Right in terms of Low end I wish to get this right. Any guidance of what qualifies a speaker to LARGE or SMALL is heartily welcomed. Thanks To all who have helped me through the formative process, the system sounds AWESOME (I knew it would) Fronts are stand mounted, tweeters at ear level, Center is below screen and aimed upward at where the ear should be, surrounds are stand mounted above listeners, aimed inward and bi-pole design 2 horns and 4" woofer.

The large/small setting should not really be based on the size of your speaker even though that would appare to make sense. If you don't have a sub then all speakers that are the largest and have the best low bass extension should be large. Normally this is your front 2 speakers unless your rears are identical.

Finally if you have a sub then all speakers should be small with nearly no exception. Only if you have speakers that can match the same low bass extention of the sub should they be large which is unlikely unless they have some massive dimentions or your sub is tiny.

Modern and high end AVR units have adjustable crossover frequency per channel so you can always have all speakers set to small and each speaker gets a different low range frequency split off to the sub depending on its bass extention which is ideal. But the thx recommendatuon which can be a good start is set all to 80 hz. Some receivers only have one crossover setting and there may be reasons with this restriction to prefer some speakers large to allow that speaker to go down lower.

What poster above me said is applicable and true, but for more in-depth info, you're best to start reading articles on AH main site - like this one:

One other tip is that the settings you change for this apply live straight away as you toggle through the options and frequencies in the onscreen menu. So put on some bass heavy music you know and love well and then adjust all these settings so you get to also hear how it effects your system live. If your speakers were meant to be large then when adjusting the crossover frequency between 40hz and 200hz it should sound just as bass responsive. Note that most music doesn't go down to the limit of many subs so be aware of this. This test above is also a good way to test sub to speaker speaker volume balance.

When one removes the stand alone sub(s) from the setup and if it does not affect the 10-100 Hz frequency response, the speakers are Large. If not, they are Small.

Thank you all for your input, I am going out to the LR to try your ideas now! Tim

Just curious where in your profile do you note your current system components, ie

"TV: TC-P55ST30 , AVR: TX-SR805. The Speaker Company 2x TST2, TC2, 2x TSB ,PA-120 Sub, FreeNAS PLEX ->OpenElec, URC RFS200, PC->Toslink-> Audioengine D1->JBL LSR2325P/AKG-K712 Pro"

It goes in your 'Signature'. Just click on your name in the top right and select signature.

Latent, I must qualify for 'dumb blonde' status as I followed your instructions explicitly and came up with :

sorry you may have to hover over your name in the top right corner and select signature from the pop up menu. If you go to any of the options to change your setting though there is also a signature option on the left.
