hi wayne, could you tell me which is better suited for surround duties?

i really like the footprint of the 1pi for my small room, but how much better is the 2pi with the 10" woofer?

looking at the specs, they have the same sensitivity, watt, and spl. i supposed the 2pi digs a little deeper with the 10" woofer?

can i comfortably crossed the 1pi at 80hz? or do i need to crossed them higher (100hz, 120hz)?

thanks much!

The one π and two π models are equally competent as surrounds. But you're right, the two π has a little more in the ~60Hz range. In most cases, you can consider them to be equivalent when used as surrounds but there are a few situations where I'd probably lean a little more one way or the other.

If the speaker will be placed in a bookshelf that tends to provide too much reinforcement in the lower vocal range already, then I'd go with the one π model. Notice I said "in" - not "on" - if the speaker is used on top of shelves it usually isn't an issue but I've heard speakers placed in shelves that emphasized the lower midrange. The one π speaker won't suffer as much in this situation, and is easier to fit into the shelves anyway.

On the other hand, if the speaker will be used on stands or otherwise away from boundary reinforcement, I'd probably lean towards the two π model speaker. It has a little more down low, which is welcome when used with little boundary reinforcement. I also like this speaker when mounted back against the wall, although the one π model is just as good in this configuration.

thanks wayne.

since they will be on stands in my room, i guess the 2pi is the better choice.

a few questions.

1) does the 2pi kit has everything i need (crossovers, drivers, etc.) besides the box?

2) finally, may i have the 2pi plan?

thanks!

You've got mail!

Kits include the drivers, assembled crossover, hook-up wires and terminal plate, a "π" decal logo and a printed copy of the plans.

Thanks I am happy with how they look but even happier with how they sound. I feel like I have a real home theatre now.
