    going with these for the bass section of my line arrays. Filtering via MiniDSP and the amp hasn't been decided on but with their high efficiency, shouldn't be an issue. I will post all measured data on the all tho far field measurements are not expected. My measurement baffle takes up to 12" drivers.

    Are you planning sealed with some boost or are you going bass reflex?

    Those should do a great job and look to be a good value compared to the other Italian made 18" pro sub/woofer offerings. What is the rest of the line array? I've always liked the idea of line arrays for their dynamics and for the more direct pseudo-nearfield presentation.

      Wow, those are going to need a HUGE vented box if you really want to use them as a subwoofer. Did you notice that Vas is 12 cubic feet? With Fs around 30Hz, you can't afford to put these in a box that is relatively small unless you apply a serious amount of LF boost using an LT. That would have to be very carefully done using the MiniDSP by the way.

      If you indeed can put them in a rather large vented box, then these will be great. Get creative...

        The arrays are Fountek/Jordan that are towering on the background of a few pictures on the DIY-NY site (check the link and scroll to the annual competition photos)
        I'd like to go with the ported design for these but let's see what the actual motors are. There isn't much information on the use of these drivers so a set of measurements will go a long way. I'll be posting info as the build starts. Who knows, may be they are terrible and I'll be sending them back.

        Large box is not and issue , Charlie. I was thinking 6ft^3 to 8ft^3 but again, we'll see what the actual motor will show. I never really like to start the build based only on manufacturer's specified data. At this point we don't even know what the distortions of the driver are, how low it can be pushed realistically.

        In addition, I am not looking to get ultra low bass out of this. Large pro parer woofers always mesmerized me with the life like reproduction of the low end. Every time I tried to use a dedicated sub-woofer driver like Dayton RS or Peerless XXLS or even higher performance Scans, I ended up somewhat disappointed.
        The woofers in the array (Jordan jx-92) are reaching in to 100hz in a sealed alignment before they start rolling off, so the Faitals will probably run 100hz and below but I'll have to look at actual slopes.

            Man does not live by measurements alone, a little music helps.

                Between 6 and 8 cubic feet is just about right for that beast. Mid 30s cutoff and 117dB at 30Hz with rated power and excursion using a 33Hz tune and 7 cubic feet.

                      not with this particular woofer. AE has a dedicated OB 18". .9Qts and large x-max

                        Drivers came in today. Packed well and no damages.
                        First surprise. They are very lite weight. Each driver weight around as much as a 10" woofer.
                        Second surprise. TS are spot on to the published. I am so use to have drivers not been anywhere near the TS of the manufacturer that I rechecked both woofers a couple of times. Qts .35 and FS at 29.9hz. I cannot believe it. Well, alright, I'll take it.
                        Quick measurements showed that even a frequency response matches manufacturer's fairly well.
                        I will post acoustic data on these in a couple of days. Need to situate them in the box of fiberglass for cleaner distortion readings. As a teas of the day, I will say that they are very good /excellent to 500hz.

                          Mount them backwards, those are awesome looking baskets.

                          If only if only.

                            Hard to see from the pictures, but it looks like there isn't any under spider venting?

                              no, there's no spider venting. The motor is neodymium slug. I am not intimately familiar with this type of magnet/motor structure. May be pro guys can chime in and shed some light on the specifics.

                              actually, scratch that. There's venting but it's behind the sleeve that seats around the magnet. I'll have to flip the driver upside down to take a meaningful picture.
