    • "Sharp definition,for a center channel speaker." by Bradon on 8/5/2013
      Overall: 5 out of 5
      Value:
      Quality:

      I used two of these in a center channel speaker wired in series (16 ohm) with a 2.0mH coil.Voices in movies that were muddy became well defined.I boosted the bass 6dbl for this speaker and received sufficiant response from these units.I am very pleased with the well defined sound and the build quailty of these speekers.Best of all is the price.

    • "Fantastic mids!" by PantherAudio on 6/30/2013
      Overall: 5 out of 5
      Value:
      Quality:

      I designed a 3-way using this great little driver as the midrange. The system uses a Dayton da-215 8" aluminum on the bottom, this fantastic little driver in the middle and the Hi-Vi K1 tweeter on top (I also have a yet to be built version with the Vifa BC25 tweeter.) X-over is about 275hz and 2.5khz. Smooth, clear and detailed. This driver is what really makes this system shine. I highly recommend this mid-woofer in a two-way combined with a subwoofer or as the mid in a three-way system.

      Have used these with a couple of different tweeters, the latest was the MCM 53-1055, each with a pair of these woofers in an MTM arrangement. I simply cannot express my satisfaction with these drivers. They sound as great as look, and they look great. Smooth low end extension not expected from a 5" woofer, simple 12dB crossover at 3K, I am absolutely amazed. If charged double the price I paid, I would still be happy. You will not find a better value in 5" drivers, ANYWHERE.

    • "ZMV5" by msnow47 on 4/8/2010

      Built the ZMV5 2 way (Zaph Audio). I am extremely pleased in the value and the quality of the speakers. I checked them with WT3 woofer tester and both tested after burn in as advertised indicating high quality control. These speakers are keepers! My son wants to build a set now.

    • "Used in the Zaph ZMV5" by jcandy on 11/19/2009
      Overall: 5 out of 5

      Quality:

      An extremely capable woofer for the price. I've built the ZMV5, and am so happy with the 55-3870 that I am designing a larger MTM version. According to Zaph, "The build quality of this woofer is phenomenal for it's price, with a well ventilated cast frame." See also http://www.zaphaudio.com/5.5test/

    • "An absolute diamond in the rough!" by bucksnort on 5/27/2009
      Overall: 5 out of 5
      Value:
      Quality:

      For a period in the 1990's I purchased many drivers from MCM for experimentation in my then hobby loudspeaker business. This little woofer is perfect for a moderate-powered system. The bass is tremendous for its' size! I used an 11.76 liter box that measured: I.D.= 6"w. X 8.5"d. X 14 1/8"h. with a 1 1/2"dia. X 3 3/16"long port for an F3 of 44 Hz.; that's right...44 Hz! You'd be hard-pressed to find ANY 5" woofer that will go that low! Midrange is very neutral to about 2,500 Hz and becomes a little shrill above that point, however.
