See what I posted above. RE is 3.5 ohm. Look at the blue line representing impedance on the link that you posted. Note the value in the range of interest 20-100hz assuming you are using it as a sub. It dips to right at 4ohms minimum as I guessed it would do in your enclosure. Set your amp for 6ohm operation for safety. If you haven't experienced any problems yet, I wouldn't worry about it.

RE and measured in box impedance curve, trumps some nominal impedance value always.

Peerless made both 4-ohm and 8-ohm versions of the XLS subwoofers. What do you mean you've been "using it at 8-ohms"? It is what it is...

Hi,

Peerless made both 4-ohm and 8-ohm versions of the XLS subwoofers. What do you mean you've been "using it at 8-ohms"? It is what it is...
I purchased the Peerless 830500 XLS 12" subwoofer from parts express. What I mean is that I have been using the 6-8Ohm setting on my amplifier and not the 4Ohm setting.

Im a bit confused really. I dont know which I should be using, and I dont know what the result of using the wrong Ohm setting. If it dips to 4Ohm, and ive set my sub to 6-8Ohm, what will be the result?
