  • "Better than expected" by vbb1964 on 9/5/2013
    Overall: 5 out of 5

    You get what you pay for and sometimes you get even more. The magnet us the full diameter. The depth was less than the original. I used these in a 2001 Optimus PRO LX5. They fit perfectly. The hole pattern matches but the original speaker had a square face stamped steel frame. Since this was round the holes don't match. I simply added washers to hole the rim down and it was as solid as the original. I am not a audiophile and a ex-Marine so my hearing is somewhat shot. Regardless. It was able to repair something that would have otherwise been thrown out. I also saved the $100 to $200 each to replace these. These sound better than my POLK 35B. I wouldn't try using these to create a woofer or sub-woofer. These are not going to handle the sub sonic frequency with sufficient force however they will play it.

  • "Not what I expected from the specifications" by drguitar on 2/22/2012
    Overall: 2 out of 5

    I used 8 of these drivers for a line array cabinet, hoping to use this in a small, low powered (300w RMS) portable PA system. I should have bought a few to test before designing/building the cabinet for these drivers. The cabinet turned out exceptional, but the drivers, no so much. They put out lots of audible distortion with any frequencies below 200hz, even at very low wattage. Unfortunately, they were unusable for me. These drivers would probably work best as mid-range drivers for a 3 or 4 way system. Anyone want 8 drivers cheap?

    I bought a pair of these 5 inchers to upgrade an old set of speakers I built when I was a kid in the 70's. I originally had (very sought-after) polydax woofers but they bottomed out with the dynamic range used today. These little drivers ROCK. My upgraded speakers sound excellent and I use them in my car. Highly recommended.

  • "Great little driver !" by speakergeek on 6/11/2011
    Overall: 5 out of 5

    I have used this driver in many designes with great result. Very good for the money. It can be fussy in the midrange, but with a well designed crossover can play smoothly into the upper register. Great for automotive use. You can't go wrong with this little brute.

  • "Cost to performance ratio is unheard of" by bucksnort on 3/12/2009
    Overall: 5 out of 5

    One of the first small bookshelf speakers that I ever built utilyzed these woofers. I studied loudspeaker design for many years, hoping to get into the business, but a different job came up. Anyway, I spent a lot of time tweeking this speaker and came up with this. I used a 10.86 liter box that measured: I.D.= 6"w. X 8.5"d. X 13"h. with a 1 1/2" dia. X 3 1/4" long port tube for an F3 of 51 Hz. I used a thin batting on inside "side walls" only to dampen cabinet. I then crossed it over at 3,000 Hz to a quality 1" soft dome tweeter with a 12 dB per octave filter. Seriously, the sound quality, from the midrange to the bass response, rivaled many top commercial name-brands with the exception of the power handling capability. I would not put more than 75 watts per channel into them and would be careful of the volume level. But with my old Toshiba 35 watt per channel receiver they sounded incredible with any type of music!!! The midrange is sweet and natural and the bass is warm and full. An excellent woofer for a s
