However, the Gear4music extended warranty scheme provides an enhanced service, and is designed to offer a higher level of protection than many 'free' warranties offered by some retailers and manufacturers.

The highlights of this enhanced warranty service are:

  • Warranty is extended to 5 years from the date of delivery.
  • Our Money Back guarantee is extended from 30 days to 90 days (terms apply after 30 days)
  • Collection and delivery costs are included for the first two years
  • Claim 50% cash back on the cost of the policy after 5 years if it has not been used!
  • Warranty is transferable if the item is re-sold
  • Loan or replacement equipment will be provided if the product isn't repaired within 30 days
  • If an item can not be repaired, a similar alternative product or cash discount (as defined in this policy) will be offered
  • The policy can be cancelled within 30 days, and at any time after that for a pro-rata discount

Please note that this extended warranty is currently only available on products sold within the EU or EEA, and is subject to the terms and conditions as detailed on the extended warranty certificate provided.

For customers in outlying areas of the country, the price of the Extended Warranty may be marginally higher, due to the potential for higher collection and redelivery transport costs.

This enhanced warranty is in addition to the standard Gear4music and manufacturer warranty policies, and the Gear4music terms and conditions of trade. No statement or condition of sale contained within these terms affects or restricts your statutory rights as defined under the Consumer Contracts Regulation 2014.

Now the KRK12s provides a larger low-frequency driver for enhanced performance that is within the budget of even the most modest home or project studio but packs the performance that leaders in the industry, like Martin Harrington writer and producer for artists including Celine Dion, Stevie Wonder, Kylie Minogue and Natalie Imbruglia, can appreciate.

The KRK12s features a specially designed curved baffle front plate that virtually eliminates diffraction distortion, enhancing pure bass reproduction down to 34Hz from the 12-inch, Kevlar woven high excursion driver cone.

The internally mounted power amplifier yields a 225W RMS power rating that delivers 110dB music and 113dB peak sound pressure levels. The line out, high-pass crossover is fixed at 80Hz with a subwoofer low-pass filter variable from 50Hz to 130Hz.

This frequency performance range makes the KRK12s the ideal choice for most existing monitoring systems. The cabinet features XLR, 1/4-inch TRS and RCA inputs, and XLR and RCA outputs, a system volume control with a range of -30dB to + 6dB, subwoofer/line out bypass, phase reverse switch and ground lift switch.

  • Kevlar 12": Driver - High Excursion woven Kevlar driver cone
