Prepare to be blown away...
Packing a sound punch in pocket size, the M4 Mk2 is an incredible improvement on a popular favourite. As with all our new kits, the M4 has been re-vamped and overhauled by high-end loudspeaker designer, Stuart Graeme Ralston, Mr SGR himself. There's now a chance for everyone to own some SGR magic, at very affordable prices. Check out the StereoNET review of the M4 Mk2 kit here. The M4 is also the perfect tonal and efficiency match for our C4 when used in a surround sound setup (see the overlaid graph in the specifications).
We also offer a more complete package to really get you started. Check out the M4 bundle which includes a Dayton DTA-120 amp, speaker cable and RCA cable.
What's different about the Mk2 version of M4?
We've started with the existing box and shifted the port away from the tweeter to provide a smoother top end. The new drivers and crossover are the secret to a major step up in sound. This is a dramatic improvement. The previous drivers were very low cost and being built to a price, the crossover consisted of a cap to protect the tweeter and a resistor to pad down its level to match the mid. This is the minimum crossover to make as listenable speaker, but a more substantial crossover will nearly always improve the sound.
What needed to change?
We faced a dilemma with the M4. It was the biggest seller and a big part of this was the low asking price. Do we keep it the same and not mess with success? Or do we increase the cost and push up the performance? The existing M4 had some cone breakup that wasn't resolved in the crossover. All mids, especially budget ones, exhibit this problem when the cone no longer operates as a perfect piston, and you can see a peak in the frequency response. The original M4 ignored this issue and the result is a forwardness in the sound. This issue was unique to the M4 and reflects budget restraints rather than bad design. We decided in the Mk2 version we weren't happy to leave the issue unresolved. The new crossover is more substantial and results in a dramatically improved midrange performance.
M4 MK2 now features LSK branded drivers. The drivers we use have performance that matches or exceeds most of the DIY favourites, but we have them made for our kits in large quantities. This means we are able to use better drivers for a given price point, than if we were to use the drivers that DIYers expect in kits. In an entry level kit like M4, the result is a dramatic improvement.
If you're an M4 owner, now is a great time to try the new version. Even if you don't consider yourself a serious audiophile, you'll hear the improvement right away.
The applications the M4 best suits are:
Included in the M4 Mk2 speaker kit:
- These are the actual measured responses, without the doctoring or smoothing which commonly occurs in the audio industry. Frequency response measurements are gated, but not smoothed. Measured at 1m distance, on tweeter axis.
- Weights are without grills attached.
- Suggested amplifier power ratings are nominal only. There is a wide range of factors which impact the performance and suitability of any speaker/amplifier matchup. 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. In general, kits from M4 upward will suit most commonly available Home Theatre DD/DTS receivers.

Great fun, great product.By: Renata Apatu on 26 January 2015My son and I made up a pair of these for his school dorm. Great fun, very well made kitset, cabinet was easy to assemble, and well made. Good to have the crossover assembled, easy, just place in box. Sounds great, got a NAD D3020 amp to power it, this combo rocks!, certainly deserves better than a 'T amp' type amplifier.
M4 Mk2 monitors: awesomeBy: Rhys on 22 December 2014So I recently ordered a 5 channel bundle, which is a combo of M4s and a C4 centre channel. One word: awesome! The sound coming from these speakers is clear, rich and very well balanced. The bass has punch and is solid, especially given that these are a smaller sized speaker, but it's the clarity in the mid and high range frequencies that blew me away. My previous HT speakers were Pioneers, which cost about the same amount as these LSK's, but I can honestly say the sound of the LSK's is about 10 times better! They are such a bargain given how good they sound! And as others have said, the customer service received from LSK is A1. Daniel went out of his way to assist and offered great advice to help me decide that these were the right speakers I was looking for. He even sent me a pair of M4's on a try before you buy arrangement. I can't recommend their products and customer service highly enough!
Excellent ValueBy: Ross Tunney on 9 October 2014I bought one of the last sets of the original M4s, and while they sounded excellent, I felt they were a little too 'bright' and so was not quite happy with them. Not so with these new kits - the sound is really well balanced, and bass is excellent for such a small speaker. The kit itself is really well thought out, and thus very easy to assemble. I have covered mine with Tasmanian Blackwood veneer and they look fantastic. I also can't recommend this company's customer service highly enough: Daniel allowed me to exchange the mk1s for the mk2s with no questions asked, and has provided lots of helpful feedback. Shipping is fast and reliable. You can't go wrong!
LSK M4 MK2 Mini Monitor KitBy: Keith Connelly on 9 October 2014Look I found this kit extremly easy to assemlble.Honestly-I have speakers that I paid over $2000 dollars in 1998 they are still great-But seem to lack something.I have tried out many speakers since 19723 Speakers like KEF ,BOSE.JBL,NATIONAL. Honestly, without a shadow of a doubt,These two little small speakers,that I assembled my self would have to be the best sound I have heard from any speaker I have listen to.Without a doubt!
