First off the bad news. We looked at the cabinet dimensions for the 4pi theater series and its 9cuft!!! That is way to big. Can we construct smaller cabinets maybe around 5cuft at a hit in bass response? Mitch already has a subwoofer, so bass isnt all that important.

Also, the good news is, Mitch is 90% sure he will build the 4pi's. He needs a good reciever with LOTS of power to drive the 4pi's though. Do you know of any recievers under 300 dollars that are a good value, and actually put out their rated power? Thanks!

Under 300? That's quite a stretch. You can find some decent power amps for that price, but not a fully integrated receiver/amplifier that is good at all.

I'm not sure exactly what you are looking for but I got a old dynaco tube amp with a matching AM/FM reciever for $120 off of ebay. It only has twelve watts of power but I've never felt a lack of power when listening to my pi 3's. With just a little bit of work the dynaco sound pretty nice.... I like it at least...

I would not bother with a new reciever for under three hundred, you wont get very much, but I would agree that if you look at audigon or ebay you will be able to find something decent for 300 bucks. Try one of the bigger Sansui, Pioneer or Marantz recievers. Some models need a little cleaning now and then to keep them from making some noise. But that is one thing you have to deal with.

If you need smaller size, I suggest the Stage, Premium or Profesional Series four π Speakers. The woofers in them work just fine in cabinets from 2 to 5 cubic feet.

Well of course you don't need lots of power with Pi's but then you already know that. So perhaps you do need the power. If so, a '70's reciever is just the thing if it works. Here's a 75 watt Marantz chosen more or less at random. Audiogon has been good to me but you MUST speak to the seller by phone to get the vibes.

I have no conection to the seller and this is not a recommendation, just an example.

Well, the problem with tubes is that they severly limit the max SPL. He wants high output, with decent sound quality too. Tubes just wont work. Ideally he would get a Crown Macrotech like Wayne has, but they cost a thousand dollars or more. He likes his music very loud, and needs a semipowerful amplifier.

Hmm, this could be a problem then. He is already stretching his pocketbook already, I think most of his first paycheck is going into these speakers! Remeber we are only college students! :-) The funny thing is, we were discussing the box size the other day, and he said they are way too big, but he would probably build them anyways! So, he might go for it, but Im not sure.

I still think he wouldnt be that bad off with a pair of 2pi's but of course he wants compression drivers.

Is there any way he can go with a sealed enclosure for the 4pi's theater series? I know you arent a big fan, since it sacrifices some output, but since the Bass isnt as much of an issue, will it still be a problem?

Also, why does putting the woofer in too small make it too underdamped? I thought a smaller enclosure would make the impedence peaks less magnitude. Or does the underdamping cause more peaking? Thanks.

With speakers as effecient as the pi's are I cann't see the need for more than fifteen or twenty watts unless you are using them to put on concerts. I never turn mine past the half-way point with twelve watts, at which point conversation is pretty much gone, and if I did have neighbors I'm sure I would be getting complaints.
