[QUOTE="BrianChia, post: 4041361, member: 576132"] The linked driver is a HiVi 3" full range. You would not need to mate it with a tweeter or a crossover. It's just my suggestion to use a full range and fire it in bipole or dipole configuration. This will help you save some money and simplify design and construction. In a bipole configuration, there are two drivers firing in separate axes but firing in the same phase. Typically you would build a tower speaker with one driver facing the front and one facing the rear. This is suitable for front speakers and will give a broad and open sound stage and also eliminate the need for a baffle step compensation circuit. In a dipole configuration, there are two drivers firing in separate axes but firing out of phase. One is pushing while the other is pulling. A majority of higher end surround speakers for HT use this configuration. Movie studios also tend to use dipolar surrounds to simulate the effects of a movie theater surround sound system. Proper wall placement of dipolar speakers can create a rear fill effect for the surrounds that minimizes "locatability" of the surround speakers for a more realistic effect. Using bipolar and/or dipolar configurations also helps to compensate for the full-range driver's poorer off-axis response at higher frequencies. It will also essentially double your power handling potential and output. And at $10 a pop, it would mean $20 a speaker, with no crossover components needed. [/QUOTE]
