wilson watt puppy 7 help and suggestions

Hi,

I own wilson watt puppy 7 speakers and recently acquired the lamm 2.2 hybrid monoblock amps.

Two questions.....First, what does wilson mean when it says the impedance for the puppy 7 is a nominal 4 ohms? Is there a difference between 4 ohms and nominal 4 ohms?
I ask because the lamm amp has a switch for whether the speakers are above or below 6 ohms.

Second Question is whether anyone has switched the tuning ports of the puppy 7's when going from solid state to tube. Here, the amp is both solid state and tube albeit only 1 tube. Stay with the 100-400 ports which is factory setting or not?

Thanks

Michael,

Do not switch the ports over to the tube ports, those of for amps with low damnping factors (Lamm's don't have that problem). Run the Lamm's Switch at the below 6ohm switch. they are an average at 4ohms with a couple of dips below that.

If you are using single ended make sure to use the short plug on the other RCA for either inphase or out of phase depending on your preamp. Even with the XLR's I believe you must have the short plug on one of the RCA's Sets.

Enjoy!

Khrys: I agree but forgot to mention that I owned Lamms (M2.1 and M1.1's)before I switched to Theta Citadel and the solid state port sounded better. Your time will be better spent adjusting (adding and removing spacers on the Wilson footers will change the bass based on the room inteactions) Remember to change out to the correct Back spike on the Watt since you adjusting the height of the speaker. Of course always put the speaker in the Zone of Neutrality using the WASP positioning method first.

Changing the back spike on the Watt plays a huge role in the mid bass sound. Refer to you wilson manual for both of these adjustments.

Karmapolice: it's been awhile since I changed the shorting plug but thanks for the correction.
