I did something that was fun for me and it turned out very nice. Depending on your room size. My goal was a under $500 system, all in. Amplifier, source, speakers, everything under $500. I wanted an efficient single driver, one for left and one for right. Used a class d amp with a bluetooth for source and amp. I used 6" full range from Dayton. How do you get the lower end frequency? I made a transmission line speaker with PVC plumbing pipe. The pipes go up against the wall to the left and right and then turn, go up a bit and are ported behind the listener. It could be argued, that won't work everything will be out of phase. It actually makes a smaller room seem larger. I have also found that orchestral music sounds wonderful. There is a huge weakness in the system as it does have a sweet spot for listening, that is about 4'x4'. For someone sitting at a desk, it could work. Not that it sounds bad, outside of this. It just sounds really good in the sweet spot. I also have another system and found that matching efficiencies of the speakers helps keep things in balance. I have some Altec Lansing A7, 500's that I use Blumenstein's for the rear and center. I tried some others but you really had to work the balance hard to make them sound correctly.
