    I'm sure the RSS390 would work to 350Hz as a woofer. Someone on here actually built a setup using the RSS390, a pair of RS180 and the RS28.

    The 8 Ohm version gave me the option for an easier load, and a bit more leeway in dialing in a match to the mids. But the motors in all of them are of the same design, good performers, good cones, and good suspensions.

      Hi Pete,
      I noticed that in the end you made a couple cuts to the mid level, with that in mind do you feel the 4Ω woofer could be used instead for an overall increase in sensitivity?

        Possibly.

        One might be able to keep the transfer functions for the mid and tweet while adding 3dB, but it wouldn't be easy. It looks like there might be just enough room to do it, but there's no margin for error.

        Moving to the RS28F might help as well.

          Hi Pete.
          I was looking for the actual measurements of this monster. Can you point me to them? Dumb me can't find the darn thing.
          Thanks, R.

            They're back on page 8. Those PCD plots were from measured data.

            We also got these plots of the system, before the final adjustments to the crossover using the individual plots in PCD.
