Product Reviews

  • "Great sound and value." by dickw1948 on 12/6/2014
    Overall: 4.5 out of 5
    Value:
    Quality:

    Wired 2 of these in series in a two-way with a GRS tweeter - all very inexpensive. Each woofer is in its own sealed box of 1.09 cu. ft. (3/4" MDF) and crossed over at 3000 Hz. Approx. .75-1.0 lb. fiberfill in each compartment. Powering them with Sony rcvr. (110W-145W per channel). They sound absolutely fabulous. I am very pleased and highly recommend.
