What would be a good woofer (6" or so) pairing to 2 of these on a sealed enclosure separate from the woofer enclosure on a tower set up?...
Just about every woofer we have will work in this application. Please contact our tech support for more help with this question, firstname.lastname@example.org or 800-338-0531 x1.

I have 4 of these drivers and i want to build 2 towers with them. Each side will have 2 4" drivers and a Vifa tweeter on a ported box right over a long box where a 6.5" woofer will be. What volume should I accomodate the 2 4"?
The recommended sealed box for a pair would be 0.16 cubic feet, but if they will be acting as dedicated midranges the box volume won't matter with them crossed at ~250 or higher.

If I were to put one of these drivers in a 0.28 ft.3 MTM box with a 1.5" x 2" port, would it perform well? What tweeter, crossover and how much fiberfill would you recommend?
These will work fine in that volume, but that port size will tune too high in my opinion. If you can fit it, a 1.5" diameter, 8" long port will provide a better tuning frequency. If 8" is too long, a 1" diameter, 3" long port will give you the same tuning frequency. Tweeter choices are very open, just about every tweeter we sell will work with this woofer one way or another. A very popular option would be the Dayton ND20FA-6 crossed at about 3,500 Hz. A couple handfulls of fill will work well, usually we recommend a half pound per cubic foot of airspace.

My bad... 0.28 cubic feet, not 0.028.

Hello, I own a pair of RtR 1530 and I have already upgraded the tweeters with DC28F-8 and noticed a big improvement. Would these Mid speakers work well as replacement for the stock speakers? I am going for sound quality, not huge power handling.
The only thing that might be a problem is the overall sensitivity. The HiVi is quite a bit lower than the woofer and tweeter so if may be slightly drowned out. You may consider something from FaitaPRO instead.
