    • "VERY IMPRESSED!" by on 7/9/2014
      Overall: 5 out of 5

      I ordered a couple of these to replace some sealed back mids in some old 80s style "monkey coffin" stereo towers.. These exceeded my expectations, I actually had to pad them down just a little to match the lower efficiency of the old woofers... I measured these mids using a very accurate reference microphone capsule along with TrueRTA software and the graph that was generated was almost perfectly identical to the curve that MCM makes available.. Ideally these are probably best used with at least a second order crossover in order to protect the driver and increase power handling, but since i was using these padded down in a low powered system i used a simple 1st order high pass (series poly cap) and they sound great... I also do believe that these could make fun & low-cost miniature midrange line arrays for PA use if you place 4 of them vertically as close together as possible and wire them in series-parallel, it would get you a respectable 99db @1w efficiency levels with 200w rms power handling, and great vertical pattern control.. Not bad at all for barely over 20 dollars!

    • "Midrange Driver" by johns3620 on 1/30/2012
      Overall: 5 out of 5

      This makes a nice replacement, Just make sure you have room for the plate that surrounds the driver it is all one piece. Nice tone and good power handling.

    • "excellent replacement" by vacantmind on 12/16/2011
      Overall: 5 out of 5

      looked for a long time for replacements for my Fisher stv-722 &stv-420 speakers. these are a perfect fit and sound just like orginals if not better.

    • "High output midrange, sounds great!" by brkohl on 2/20/2011
      Overall: 4.5 out of 5

      This midrange does have excelent features. It does have 94 dB SPL as advertized. I used a 12 dB xover at 900 Hz to be clear of nonlinearities close to the 700 Hz resonance. I will buy more. Be careful of the paper cone as this is very delicate, protect it!
