    It could simply be the challenge to use this combination of speakers and get the maximum of each.

      I've always though that the term FAST is really an odd acronym. There are just some methods that don't need a goofy name. I would say this speaker would better be labeled as a 1.5 way myself. I'd say it looks like an ok build if you don't mind the sound of a full range driver. I don't like the massive rise in the top end. It's only a 4 ft tall speaker and the full range drivers center is about 35.5" which should be pretty much on axis and ear level when sitting on a couch. That will make that rising top end even worse. If it were me I would try to tame that driver's top end some.

      If I wanted serious volume I would probably go with a bigger full range driver that can take the power. He says it is crossed near 400hz, so a bigger full range driver in the same enclosure volume likely won't be a problem. Even better might be to use a coaxial and convert it to a 2.5/3 way. If one were going to go through the trouble of taming the rising response or changing the filter for a bigger driver.... it wouldn't be much more work to change it to a 2.5 way. It is a neat looking design, but I think it could be improved quite a bit and keep the theme imho.

      I like full range drivers, but mainly when augmented with an extra bass speaker and a super tweeter, essentially making a 3-way with the full range covering the majority of the spectrum.

        haha
        I had not heard that term before today and thought the same thing.
        He says it is crossed near 400hz,
        I didn't see that that on the Emil Attlid webpage.
        If so the 600mm separation between drivers is excessive *
        ( not very attractive either - but that's just aesthetic opinion )

        * This could explain the statement
        Vertically is a bit troubled due to the distance between the drivers

              Well I want to I just don't want to build something that's like one of those stories like on undefinition of first time builds http://www.parts-express.com/peerles...ofer--264-1098 http://www.parts-express.com/peerles...-ohm--264-1381 What about this woofer and this tweeter in a 2.5 way with my w4 TB? Now I'm back to breaking the rules about first builds again. Sent from my iPhone using Tapatalk

                That would be more of a 3way.

                  The tweeter will want to be crossed at 3.5K Hz or above. You will have a hard time crossing the woofer much above 1K Hz. That leaves a pretty big gap.

                    You know maybe I'll still just use this as a learning experience and build it. If someone would like to help me correct the the xo design for a w4 version of that driver great. If not I'll build it as is. If it doesn't live long term in my living room it will get paired with a Sansui which I think is rated at 22 or 25 watts. Is that even worth adding the w4s? I do like to play things loud at times. Sent from my iPhone using Tapatalk

                      Note this bit from the link you provided:
                      The low end is a bit hard to drive with a min. impedance of 3 Ohms. I recommend a beefy amplifier for these, preferably above 150 watts per channel and a good power supply.
                      His Impedance/Phase Graph would support this.

                        Well then I'm clearly out of my element. I'll build them and experiment. Figure out how full of **** I am. Sent from my iPhone using Tapatalk

                          Looks like a great speaker for single men.

                            Nah, the enclosures I just built are 48x11.25x12.75" and I am married. I also have a 4.5 cu ft and 12 cu ft subwoofer too. I have to admit I have a pretty cool wife though

                              25 watts? Look at these. I built them for a 17 wpc tube amp, very happy.
