Warranty Policy

Product Warranty 

All LSK speaker kits are covered under a 3 year warranty. Warranty coverage includes manufacturers’ defects on all components such as woofers, tweeters and crossover circuits. Damage to speakers is usually caused by an underpowered amp which is clipping due to being driven too hard. Damage to speaker drivers and kit components caused by over-driving the amplifier or the speaker is not covered by warranties*.

Satisfaction Guarantee

If you purchase a kit from us and are not absolutely satisfied with the sound quality then you can return it to us within 14 days for your money back (this applies to kits only). All you pay is the freight cost back to us provided the components are in as-new condition and you have kept the original packaging. You must return the cabinets as well even if these have been partly or completely assembled.

The Box Build Warranty 

We are certain that you will find the cabinets that are supplied with our kits easy to build and of an excellent fit and finish. If, however, you are not absolutely happy with the finish you have obtained, you can return the cabinet to us and we will supply you with a replacement cabinet at a nominal price.

* Suggested amplifier power ratings in our specifications are nominal only. There is a wide range of factors which impact the performance and suitability of any speaker/amplifier matchup. In general, kits from M4 upward will suit most commonly available Home Theatre DD/DTS receivers.
