What is the difference between this model (SUB-800), and the SUB-80, you ask? As of this writing, $10...and...the other model (SUB-80) you asked about has rear-firing dual ports that are not flared. This model (SUB-800) has a single downward-firing flared port. The new downward-firing flared port should mean you'll have slightly less port noise during loud passages of sound, even with a modest 80 watt RMS powering the 8" driver.Also the SUB-80 doesn't have feet, the SUB-800 does. If you intend to purchase, and place the SUB-80 enclosure on hard floors instead of carpet, you would probably want to purchase some footing for the footless enclosure. I suggest something like Dayton Audio's DSS2-BS Black Chrome Spike Set (Part #: 240-660). As of this writing, they are on sale for $8.95. That's a great price on those, Parts Express!Bass sound reproduction is much more wonderful if your subwoofer enclosure isn't vibrating against hard flooring during loud passages of sound, or even slowly vibrating to a new location in your room.Given the slightly bigger box size, added feet, and what appears to me to be a different, and possibly upgraded woofer design, this SUB-800 model will probably give cleaner deep bass than the SUB-80...ESPECIALLY if placement is on a hard surface and not carpeting. Let me note that if you intend to place the SUB-800 on carpeting, you may experience ever-so-slightly less bass volume, because a bit of sound from downward-firing port will be absorbed by the carpeting itself.That is my educated guess, given what I currently know about the two systems. I have no technical test data to back up that claim, but I do have over 40 years experience with equipment and enclosure designs in the professional music industry.Also, flared ports DO inherently exhibit LESS port noise than most non-flared designs, but I wouldn't let that new feature alone guide my choice if I were you. Port noise USUALLY isn't a big problem in lower powered systems like the two we're comparing here. However, when lots of power is being fed to a large, long-throw design woofer in a ported enclosure, port noise can and usually does become more of a serious factor, and a much bigger consideration during the enclosure design.I once heard a dual-ported sub enclosure (made by a very well-known, reputable name in the industry) that made terrible port noise, even at modest home theater levels, with only 150 watts RMS being fed to the 15" subwoofer. It seems the ports' pipes (plastic tubing) were resonating at certain frequencies when going beyond a certain volume threshold. The moral to that story? It's always best to listen to such things for yourself, before making a decision, especially with higher priced systems.That leads me to my next acknowledgment...Not to toot Parts Express's horn too much, but them allowing us customers to have the option to try-out and hear these systems for ourselves BEFORE committing to final purchases, is a HUGE plus that Parts Express gives us. With sound devices (where quality tends to be a subjective judgment call for listeners) it's important that we listen and determine for ourselves what sounds, "good".As the two previous members answering your question quite correctly pointed out...whether or not you'll hear noticeable better bass sound with this model (or the other), will probably depend on your application and placement of the enclosure. I'm just adding to their knowledgeable comments by adding that you should also consider the surface material the enclosure will be placed upon, given the two differing port placements, and configurations.Good luck!
