    You're telling me.
    Check your lips at the door woman. Shake your hips like battleships. Yeah, all the white girls trip when I sing at Sunday service.

    Before heightened security guidelines and photo badges everywhere, you could get pretty far into many research laboratories with a lab coat, a clipboard, slightly nerdy clothing and a bit of smooth talking.

    The "fluid" is air and the "coupling" is the increase in air pressure when playing sound by putting an active driver on the wall of the same sealed volume as the passive radiator. Polk's advertising puffery ("Welcome to Marketing! Two Drink Minimum!") usually started with a grain of truth, and then reached for the special long-words thesaurus... :)

    So then a vented cabinet employs a Fluid Pump?

    In the case of PR's yes, in the case of a port, no. You were originally quoting my post and I left it alone because, in this case, you don't know what you are talking about. Joell is correct the air is the "fluid" so to speak (remember chemistry) and the PR's are "coupled" to the mid-bass drivers (remember physics) as they can't react w/o the mid-bass drivers reacting. I'm done trying to explain the basics here. Duanage you claim to have all this practical experience building speakers, yet you don't grasp this very basic principle. :rolleyes: .

    It's a knock out by H9 in the second round.

    Duaneage might also have just been continuing the marketing joke... :)

    Though "Fluid Pump" sounds a bit... off-color. I'm sure that's why they chose PowerPort (tm) instead. It's got alliteration, and the word "power" in it, and it's easy for salespeople to pronounce... winner! :D

    Duanage... I'm very much looking forward to your finished product, or at least the testing phase of the M10 redesigned, and of course, your audition testing. Any chance you're anywhere within a 100 mile radius of Greenville SC?

    Duanage... perhaps you could explain 'Baffle Step Compensation' differences alluded to in an earlier post in this thread... a designer said it could be a problem if a narrow MTM cabinet width were used, suggesting I make the front baffle an inch or two wider (assuming he meant narrow to mean the front baffle wouldn't be much wider than the 6.5 drivers as many MTM designs tend to be configured similarly.) My plan was to use the following approximate dimensions: 33.5" H x 9" W x 16.7" D The RTA8's design is 9" wide already which might be enough to compensate for whatever the "baffle step" issue is really addressing. I'm also curious about the internal cabinet architecture, and whether or not any chambering will be necessary.

    Certainly for any company marketing pushes the envelope of truth vs. hype. But I'd like to think Polk is closer to the truth than some others. PowerPort is definetly a marketing term, but when they explain it, it seems feasible it's a more powerful port than someone else's. I've always thought Polk has walked the line between marketing hype and reality pretty well. The old terminology "fluid coupled" is not only technically correct but sounds pretty cool also. Of course eveyone else's PR system is the same way ;)

    Too bad most consumers won't give things a 2nd look unless it has some sort of buzz word attatched to it. Thankfully there are companies out there that can use buzz words and still deliver with the product. Polk is one of them.

    Also to throw one more thing in here. If said buzz word describes something that is patented then it had to demonstrate it worked above and beyond whatever the normal product already does in the marketplace. Meaning it has to be significantly different or a significant improvement on what already exists. (not saying fluid coupled or powerport are patented) Just throwing it out there. :)

    Polk's Power Port (tm) is positively patented... are you ready to poke a hole in your piggybank yet? :D

    I just looked in the "Education" section of the main website. Power Port wasn't quite enough, they have another technology buzzword for subwoofers with two ports and some internal chambering, named... wait for it...

    Power Port Plus :eek:

    (Bartender, as long as we're on the expense account, I'll have another martini... thanks...)
