    When you say "2 tweeters", you mean 1 per cab, right?

    Also, "X-Over Pro" can't be accurate 'cause it doesn't use FR and impedance files (.frd and .zma).

      Yes 1tweet per box. Also I'm using fibglass r13, how much should I put in each box, don't want to overdo it.

        None, home insulation glass isn't a good damping material. Polyfill is much better.

      Also I've been running these speakers uncrossed, just the woofers, trying to break the woofers in playing loud heavy rapp, I live in a mobile home, I turn it up,full volume,go outside, and the trailer is vibrating from the front all the way to the back, like a black dudes car!

          Here's my "stab" at an XO for your 3-way. It should have a "moderate" amount of baffle-step (around +3dB?).
          Cross points are near 400Hz and 2.5kHz. Runs about 86dB.
          HP - 2nd order w/an "L-pad" for attenuation: 6uF series cap, then a 0.50mH "shunt" coil (to ground - a #20 is fine here). "L" (series & parallel resistors): SR = 4n(ohms) / PR = 4n
          BandPass (for 6") - also 2nd order w/"L": 0.50mH series coil, 68uF series cap (npe?), 3.0mH shunt coil (iron-core good here), 15uF shunt cap, L-pad: SR = 3n / PR = 2n
          LP (woofer) - 2nd order: 6.0mH (iron core) series coil, and a 120uF npe shunt cap (to gnd).

          A "solid" 4ohm design. Z-min maintains 4.0n @ 50Hz, 2nd lowest is 4.5n around 1.5kHz.

          This SHOULD get you into the "tuning range". Had files for the woof & mid, and FRD was given for the (GR-supplied) tweeter. I simulated the .zma data from specs.

          If the mid/tweets end up too quiet, there's plenty of room to "de-pad" them.

            Also, I will be using a felt doughnut around the TWEETER.

                Do you have any pictures you can share as you're building?

            • #24
              I can't seem to atach pics,tells me I have exeeeded max size, makes no sense, it's just 1 pic at a time.

                It means that the individual photos are too large. Scale them down.

            • #25
              I will gladly share some pics, I don't think they look that bad really, think they turned out better than I thought they would, considering I'm not a pro carpenter 🪚 or cabinet builder, I'm just a lowly house painter,or was, disabled now.

                  I do it with the photo editing software on my PC.

                  The Windows Photo app will let you resize too.

                    I recommend against using these.
