Well no such luck on the impedance option in my avr, I'm assuming it auto detects weather a speaker is 8 ohm or 4 ohm? Another question came to mind, how far do you recomend sitting from the speakers? I just measured the living room area and it's about 27 feet long and 10 1/2 feet wide and 7 1/2 foot ceiling with a doorway opening to the kitchen area.

Nah, no way to auto detect. It's there somewhere unless it's a physical switch on the back panel.. How did you switch it to 4 ohm in the first place?

If you want to estimate amp needs/capabilites this might help http://myhometheater.homestead.com/splcalculator.html

I never changed it, I bought the reciever used from a private seller so I was wondering if maybe they set it 4 ohm and I've just never realized it.
Okay, no, believe the default setting is the higher one. Did you do a full reset on the receiver to remove the previous user's settings, though?

No I did not do that, and I've ran audyssey several times since I purchased the receiver. Do you recomend I still do a reset?

Re-running Audyssey should reset the things it affects. I'd just do a factory/full reset on receipt of a used unit (instructions in the manual) as a first step.

Could also check if there are any firmware updates to be installed.

On my Marantz, impedance selection is done through a non-intuitive sequence of button pushing on the ‘hidden’ front panel.
All for doing a factory reset, too. Start fresh! (Even though Audyssey should reset everything it has control over to the latest calibration, still I like the idea of resetting everything manually if you choose not to do a full reset. I am uncertain if the impedance selection will reset, though: def double check that.)

Pretty sure they come from the factory in the higher impedance setting so the reset should work for that....

I agree with the factory reset thing, but there is clear instructions on page 42 if the OP wants to just do a quick check to satisfy his, and our curiosity, prior to re-running Audyssey.

owner's manual page 42:

As Ryan pointed out earlier, the UF5 has quite low sensitivity, and 4 ohm nominal, the combined effect can be seen below:

1557232716771.png


So there is no way the OP can hit reference level with the system he has, but if he's happy with 78-80 dB average and 20 dB on top of that, the system should be able to deliver, given that it is only a 2.1 system.

Aside from the system being limited by the output capability of those speakers, the main culprit appears to be the relatively low output from his cable box (is there a volume control button on the remote?) as he seems happier with other sources such as the X Box.

I would suggest the following:

1. Sitting closer if possible, say 9 ft instead of 10.7 ft.
2. Check the impedance setting, better still re-run Audyssey as suggested, to make sure it is set to 8 ohm.
3. Set crossover to 100 Hz, the sub has f3 at 148 Hz, so take advantage of that.
4. Angle (toe-in) the UF5 to make sure they are pointing to the main mic position
5. Turn Dynamic EQ on, use ref 0 for blue-ray movies, ref 5 or 10 for cable box, or music listening..
6. Make sure "ECO" is "Off".

Re-run Audyssey will take care of 2 and 3. It should be quick and easy to do for a 2.1 system. 5 is important for movies if listening at 5 to 10 dB below reference level. It is better than bumping up the sub level by 4 dB. As HD said, how much to bump up is a matter of taste, but any such bump is applied across the board regardless of the volume position and frequency, whereas DEQ is dynamically done to restore the balance to that intended by the mix.

Edit: I added item 6, that needs to be checked too.

Thank you, your information is very helpful and am going to try all you have suggested, it gives me a reason to play around with my gear which I love to do lol. I am off work tomorrow, so I will be measuring and testing and moving things around and hopefully dial it in a little better. Thank you guys
