Sorry! No WAF points there. Nice picture on that TV. Also I am really pretty darn sure that two 8ohm speakers in parallel is a 4ohm load.

No W, points not needed. I would think my setup would be worth major doghouse pounts if I were attached. The HTPC is in an old ATX case that I havn't bothered putting the sides back on, cables everywhere...
I will eventually clean things up, but until car sales pick up again (not this year!) things are tight.

Fred if your running two 8 ohm M2s in series wouldn't that be a 16 ohm load on the receiver, if you ran them in parallel that would be a 4 ohm load.
Just curious why you chose to wire them in series?

Rick, you could be right. I really do not understand that part of electronics very well. I put them in series becasue someone here said that was the better way to go (to avoid another 4ohm load I think).
Does it really matter?

Fred, from another site....
When adding two speakers in series it will increase the ohms. When adding two speakers in parallel it decreases the ohms.
In series, when increasing the ohms, your amp will not put out the power it is rated at. 100w at 8 ohms may only be 60w at 16 ohms.
Parallel. If you go below the ohms your amp is rated to run safe at, it will burn out your amp.
I thought most folks wired in parallel, that's how I did my two center channels, I believe wired in series the speakers can clip easier due to the amp not supplying the sufficient power. I believe we're talking about really putting the power to the speakers though, I don't know how high of dB's you like to listen.

Yes, when two speakers of the same impedance are connected in series the resulting impedance is the sum of their impedances; when connected in parallel the impedance is half of the individual speaker impedance(the calculation is more complex when more than two speakers, or those having different impedances are involved). Of course simply using the nominal rated impedances doesn't give a complete picture of the result, since the impedance can vary widely at different frequencies. For example, my M22s drop to about 3 ohms in one frequency range, which is lower than the M80s ever get.

John in your estimation is one preferred over the other, regarding series or parallel wiring of home speakers?

Sure, wiring in parallel makes the speakers easier to drive because of the lower resulting impedance. There's a limit to this in that if the higher current that results from the lower impedance causes overheating, the protective circuits will shut the amplifier down.

Since we all like photos...and since I always get confused as to which is which...AND before someone else asks.... how is this? (If it isn't 100% clear, offer suggestions and I'll replace it!)
