      Awsome speaker for the price. Dropped right in my pioneer boxes. A bit tight but will loosen up after they break in. Pushing them with a Harmon Kardon av520 reciever. Big magnet. NIce size voice coil. Pretty good xmax. They jam for sure better made than the GRS woofers ive used in the past. Well worth the money even at double the cost. I give them a 5 out of 5 . Well done MCM

      I own ohm's "I" series that is a 4-way setup that can be bi-amped sub/ highs. They use a 12"sub, 8" mid-bass, 5 1/4" midrange and 2 dome tweeters. The 12" and 1 tweet face forward and the 8" mid-bass, 5 1/4" midrange and other tweet face up. They screem like club speakers! My cats use to sit on the 8" mid-bass and they tore the old paper cones. I replaced the 8" mid-bass with the 55-2950's and they sound as good as the ohms , that cost 140$ each to replace. Good mid-bass

      I used two of these to replace the original OEM woofers in a pair of ancient two-way bookshelf speakers. Even though these woofers are supposed to be best in ported cabs, they punch really well in the old sealed cabs. Fed with a 200w Pioneer surround receiver, they are clean as a whistle and punchy even at living room "party" volumes in stereo mode. They are responsive at lower levels in surround mode for movies and the cabs sound great for an 8" with separate dome tweeter two way sealed system. The speakers were well-boxed and arrived in perfect shape. I wouldn't hesitate to use these again if another project comes up needing 8" woofers. Good job, MCM.

      Bought two small guitar amps from a garage sale for my two sons to practice with. Both worked but had severely damaged woofers. Dropped one of these in each, I'm amazed. They sound great, seem to handle all we throw at them , and look fine. I can't imaging doing any better than this for the money. Highly recommend.

      ok for the money but dont expect miracles I bought these for a bass cabinet , they fart out and dont handle the freq range they boast but for the money hey I cant afford eminence they seem to be built well though. I dont think I would use these for pro audio cabs

      Good bass definition. Some woofers are rather bright in the midrange frequencies making them well suited to 3-way systems. This is not one of those woofers. The mids aren't overly bright or honky. Just right for classical, blues or jazz. It would do okay for country or rock if you add a midrange driver to punch up guitars and keys. Pair it with a nice silk dome or ribbon tweeter and you'll have a 2-way system that is easy on the ears. Almost a velvety, smooth quality. I ordered these intending to use them as a mid in a 3-way professional audio system but decided to use them for a 2-way with a planar tweeter instead. The woofers I was using with the planars are a lot bright and therefore much better suited to the pro audio application. Seems you need a number of different speakers for different uses and these are great for general, casual listening when you don't want the listening fatigue to set in from being exposed to hours of music in a day. The mellow quality of the sound produced above 1khz makes this a good choice.

      Needed cheap and dirty replacement drivers for 8 plastic cabinet speakers located throughout a large recreational facility that had been vandalized. Each are a two way speaker with a port, and simple cap/coil crossover. While I have no way to measure the response or any of the other specs, these speakers all sound fantastic, far better than expected. And some are driven very hard. My customer was just looking to get buy for now, but he is totally happy and I am a hero. For the money, I don't know how I could do any better.

    • "Very Poor Quality and Sound" by davisbass on 9/30/2011

      First off, the dust covers were not glued on all of the way. Fixing that I see the magnet was fractured / cracked throught on 1 of the drivers. Installing them in a sealed and also a ported enclosure the drivers were a far cry from the (94dB w/m ) through a T-calss amplifier and also a 1000 watt Carvin power amp, the driver never put out enough volume to even have to yeel over . A loud talking voice and you could be heard over this speaker at the point the speaker is starting to pop & distort. I don't know how anybody can review this as a quality speaker.

      This Speaker is an excellent value for the money ---- in fact I have carefully compared it to other 8" Speakers costing up to 4X the price of this one. I am a musician and electronics guy. Capacitors in Crossovers were changed out to try to get other similar 8" Woofers to sound as good or better and I could not. I am just a customer of MCM -- not an employee. I have also had a similar experience with MCM's Professional 8" Woofer, Model # 55-2960. Paper Cone, 2" Voice Coil, SPL numbers at 94dB/Watt/meter are great specs for a Speaker costing many times this price. Two thumbs up!

      I have been building ext. cabs for the last year. I use this speaker in a solid pine, dove tailed cab. I sell them at a local music store. I tested many different speakers using the guitar teachers and the customers. This is the one that beat the "NAME" brands. Buy the sound not the name!

      With two decades as an engineer with " the most repected name in sound" - rhymes with "toes". This woofer is an unbelievable deal. Whopping output, whopping value. Great for the novice and professional alike. Built like a tank, drives like a Ferrari.
