    Great Woofer - Excitement!

    Overall: 5 out of 5

    This is a great Woofer! I built my first pair of Speakers back in the 80's with JBL LE-14A - LE-20 . After 10 years upgraded them to 3 way with LE-5 and TI-35 titanium tweeter - Lancer cases. I loved these speakers, but dismantled them because the case size was too big for the condo. I have been used to the 14” LE-14 with thundering lows, no sub woofer needed! I had my cousin, who used to work for Paragon Acoustics in the 80's build me a knock off of the Regent cases. I modified the innards a bit because this woofer is different. Paragon used 2-6" woofers. This little 8" punches the sound out! I tuned the internal port to resonate at about 30HZ. Deep low clear bass, smooth clear midrange from this woofer much like the 14” JBL’s. I am impressed! I Used 4.5khz 12db / octave crossover. Using no tone controls with Crown SL-1 / PL-1 playing off cell phone. I am listening just to one! Getting the components mounted in case #2 , cannot wait to hear them as Stereo! More later.

    8 in Carbon Fiber Woofer

    Overall: 5 out of 5

    Purchased this speaker for my 19 year old Boston Acoustic cabinets and wow the new technology is impressive.They match perfectly with the tweeter with slightly better base response than the previous speaker. Rebuilding my old speakers was a great move, and quite affordable.
