Audtioning, Bypass and "small" speaker setting
Will be going to a shop to audition speakers. That's why I need to go prepared so I know what settings to tinker with.
Small even to bookshelves with 6.5" drivers?
"Bypass" meaning direct mode or without signal processing. Something like DVD/CD AUDIO SIGNAL > AVR > SPEAKERS.
For surround speakers, should I go with small or large setting? P162s have a 6.5" driver + tweeter. Specs indicate lower bound frequency of 49hz.
First, try to get the set-up in the store as close to what you will have in your home as possible: speaker distance, speakers size, sound level, AVR?
Take the music you like. I would also take some with voice and instrumental, especially brass. You want good voice for HT and brass brings out the speaker clarity.
Also take a note pad and write-down the differences when you hear them.
As you narrow down your speakers to 2-3 do a back to back listening ti the speakers you like then an A-B-C-A-B-C comparison works best.
Here is one of the best auditoning recommendations I have seen

When someone says bypass, bascially they are saying without and sound enhancements, treble, bass, no signal processing. Some AVRs actually have a button that says "bypass' and alow you to retain all you settings. If the AVR doesn't have that you just manually remove all signal processing.
As far as bookshelf speakers being set to "small", that is because most, but not all, bookshelf speakers do not have large speakers and can not effectively handle bass and lower frequencies without distortion. The "small" setting can restrict the sepaker to only hthe high and mod frequencies by having a crossover to the sub output for lower frequencies. Most of the time the cross-over frequency can be set between 50 hz and 200Hz; if is cannot be set then it is usually around 150 Hz. So the typically bookshelf speaker setup is small and a subwoofer is used for the lower frequencies.
The "small" or "large" setting however, really doesn't apply to the speaker size. It is determined by the low-end frequncy range a speaker can handle. If a speaker isn't designed to handle a 100 Hz frequency, then it woun't sound good if you send a 100 Hz frequency to it.
==========================
Some other things to consider:
(1) mose speakers have a nominal impedance of 8 ohms and most AVRs are rated fro 8 ohms. If you get a speaker with 6 ohm or 4ohm nominal impedance, the speakers will require more power. A 4 ohm speaker requires twice as much power as an 8 ohm speaker.
(2) Also look at the speaker sensitivity. This is a measurement in dB ( logrithmic) and determines how effciently the speaker will produce sound for a given amount of power. 80db is low effciency and will require a lot of power, 90 dB is average and 100 dB is very high efficiency and will produce loud sound with minimal power.
Good Luck!
