This woofer upgrade kit allows customers who have the original M4 speakers (kits or finished) to upgrade to our new LSK drivers featured on the M4 Mk2 kits. It's a simple drop-in replacement that requires no modification to the original cabinets or crossover.

The new driver has a larger magnet and voice coil for increased power handling. It also has under spider venting and an aluminium shorting ring that result in a massive reduction in distortion and compression!

We gaurantee you will hear significant improvements:

  • Increased dynamics
  • Better bass
  • Lower distortion
  • Smoother midrange
  • More detail

The best $99.00 upgrade you'll ever buy. A serious M4 transformation.

Original M4 Upgrade Kit : Apparently the M4 can st

By: on 1 February 2016
I own x5 original M4's as review samples, which I purchased outright from back in the day, when Marcus ran LSK from Keilor. They haven't been used since those days, however the need for a more discreet system in the living room saw these seeing the light of day again. With the old x5 VAF DC-X and x2 HSU VTF3 setup with Rotel seperates being put into storage. I setup the old MK1 M4's with a mid-range Yamaha RX-V10165 receiver & LSK S100 sub for a nice discreet setup. The original MK1 M4 is a pretty decent kit however it felt a little wanting after a few days of listening. The basic design is sound however they're let down by the cheap Response drivers. Bought this upgrade kit to see if I could improve the front stage of the 5.1 setup. After a brief run-in of the drivers, the verdict : the upgraded woofers deliver as promised:Increased dynamics, More Detail, Lower distortion, Smoother midrange, Better bass. A better loudspeaker now indeed. Now that the woofer has been changed the tweeter is definitely lacking.....can you see where this is headed? The LSK M4 MK2's indeed look tempting now. Well done to the new custodians of LSK.
