  • Thank you Matt, for helping me to finally get The Passive Agressives I've always wanted!

    They sound great, look amazing, and wifey is very pleased that I found speakers that can go anywhere...though I'm still working on finding the perfect placement for them.

    Stay tuned!

        You are very welcome, I am glad we could make that happen. It was nice to meet you!

        • Would a larger Sub (perhaps a 10”) mesh ok with these crossed a little higher?

          • Out of curiosity, do you really hit those notes around the 50-60hz mark with these? Being this small, could one use this in a portable BT setup as the 0.1 ch, obviously without the tweeter? Getting good bass out of something this small makes my mind tick in mysterious ways.......

            I'm thinking PE 2.1 class D amp, 3 chambers, this in the middle, driver facing upwards, PR's front and rear and in there own little chambers maybe a 2-2.5" Full range? I still want to find a use for the 2.1 amp chip....

              Just for you I found an online tone generator and hooked up my PAs. Sound is present until 60hz, fades fast and is mostly gone by 55hz. Unscientific test by a non designer.

                Interesting, thanks. Could that be a limitation of the enclosure size and pr weighting? I have always failed to model a PR in Winisd and abandoned these projects but always wanted to try. One driver I thought would be good in this size box is the peerless as it talks about half space sensitivity on other websites.

                Anyway food for thought coupled with the matched peerless PR.

                  It is a combination of a lot of things. Placement, room, nearfield or not etc. Nearfield they have a surprising bottom end but in a larger room from a distance may lack a little below 60. For their size 60 is nothing to shake a stick at really.

                  I never paired mine with a sub for use in my kitchen or at my computer but adding a sub is never a bad idea for any small system.

                    interesting matt, yeah after getting a ND65 with 2x90 PR's to get around the same F3, i think that is a good amount of bass for sitting at a computer enjoying yourself. I think to use mine in a similar fashion i would need a tweeter. I really want to try these after reading through all the comments, just not liking the exchange rate, additional tax i would need to pay and shipping :( Maybe one day, fingers crossed.

                    • rutu, I realize that part of you looking into the PAs is to do a(nother) PR design, but PRs DO add to the co$t.
                      I can tell you that sometimes I can't duplicate a vented box rolloff using (existing) PRs, but I've never seen a PR design that couldn't be matched (or bettered) using ports (they have fewer design constraints w/out the PRs).

                      I'd think that (aside from a box vol. increase) if you did a non-PR vers. of the PAs (esp. w/your printing abilities) w/a (folded) slot, that you'd be happy w/them.

                        that they do Chris, even my crazy attempt at the 2inch variant comes close to the PA's in cost and i even had the kit in the cart ready to buy last week, but pulled the pin after i couldnt get the right model happening right, but to be honest i've only ever been able to get a PR to model nicely once, the rest has been failures. I will tell you one thing, i wont be using the knock down box if i ever get this kit, 3d printing most likely.. At the moment i'm trying to learn how to do a cross over so might go that ported option still yet.

                        • Here is my setup with these little guys. I run them with the Tang Band sub.

                          • Nice. How do you like them?

                            • The setup sounds great up close. PA's are not going to fill a room with sound. Have them placed about 2 feet from my ears. Same with the mini sub. Sub in the middle, PA'a spread to the left and right for separation. Picture is not actual placement. Build an enclosure 4"x4"x4" from 1/2" MDF(external dimensions) for this Tang Band W3-1876S 3" Mini Subwoofer. Sealed enclosure for tight crisp bass.

                              • I feel like the PA's could easily pump more bass than that tiny sub. Also, if you had a larger sub, perhaps the classic TB 5 or 6" Voxel style and a proper high pass on the PA's you could very easily fill a room.

                                Not that you should change anything, that's great for near field PC use so if you're happy that's awesome.

                                  Yeah, the PA's need a sub. I am happy with my setup. The mini sub provides the bass that the PA's are missing. I'm sure the PA's are fine as a stand alone full range speaker but the mini sub really helps them. My 6.5 inch tang band sub is a bit too much bass for a PC setup with the PA's. My setup sounds better than the Harman/Kardon 2.1 system I purchased many years ago.

                                  The 3" sub provides much more bass than the PA's! Its not an "I feel". Its an I built and hear it. Thanks for the feedback.
