Anyone know where I can get an Entech Number Cruncher 203.2?

Hey everyone, I am new to the audio scene. I have reviewed some products and am going to purchase the psb b25 and use just them for now and later I would like to get the psb t55 and center channel and sub. I am young (19) and this system will be for half music and half movies. I need advice on what time of amp to get? pre/power or integrated? Or to get a receiver? If a receiver is the pioneer VSX-80TXV or the Model 1070 A/V Receiver? I need help badly which type or amplification should I have to make the speakers sound the best witha budget of less than 1000 on the amp(s) or receiver.

It struck me last year when I was toying around with extending the sub bass frequency response when experimenting with carpet tubing placed over the (air duct port).

This time I used a different approach with a small piece of plastic tubing about 7

Hi all: I have a Kenwood KR-A5070 100 w x 2 channel home receiver now powering 2 Technics speakers SB-S409 8 ohm speakers (15" woofer). I had the same model speakers w/ 12" woofers until recently when I had the 15"-ers handed down. All equipment is mid-90's vintage.

Problem...doesn't seem like I have enough power to drive these speakers...sounded better w/ the 12's but I want to unlock the power of the 15's!

I can't seem to find home receiver over 120 w? All I want is 2 channel. Will the 120 w make a big difference?

Just a question out of curiousity. Some speaker designs are sealed & others are ported. Now granted, the designer had specific goals in mind for their performance by choising one of the two designs. What is the real difference between the two? Does a ported speaker provide more bass than a sealed speaker? Does one design perform better than the other, & if you were to stuff the port holes how would it effect the speakers performance? Could that possible harm the speaker? I think it's all about moving air inside the cabinet.

Ok, so my knowledge is quite limited, much like my funds for this project. But...

I was recently given a Pioneer Elite VSX-80TXV Receiver. Seems like a decent receiver, i have it working with my Plasma connecting a PS3, Wii, and cable box with no issues.

However, it's running crap speakers that my roomate had from a HTIB. So i want to begin to build my own system, but i need to do it one step at a time.
