    Not been ale to give a full power test yet but during a simple check at “ home volume” these speaker sound both full and crisp in my Peavey 1x12 and horn cabs. Chassis look good and solid and cone quality and installation appear top notch. Obviously only time will reveal the longevity of the drivers but initial impressions are good meaning these units offer superb value for money.

    What is not covered with the guarantee?

    If we find a genuine fault or defect in your item that shouldn’t be there based on normal use, then we’ll repair or replace it for free– no questions asked. But, if that speaker has been unloved or beaten to within an inch of its life, then it might be time to buy a new one! In any case, we’ll review each case and will let you know if we can fix or replace it.

    The warranty stated above is the sole and exclusive remedy and BishopSound Limited’s performance shall constitute full and final satisfaction of all obligations, liabilities and claims with respect to the Product.
