We can supply range of loud speaker kits using these Markaudio point source speaker drivers, along side the other speaker components we retail like Jordan, Cube, Neutrik, Hypex and more traditional multi way speaker kits. We also offer our own line of amplifiers that offer a high performance to cost ratio.

As speaker cabinet builders, we are particularly pleased to be able to offer some of the best DIY speakers available, using the best loudspeaker drive units, as an alternative to commercial speakers and electronics that genuinely compete on sound quality at a fraction of the cost, whilst maintaining the manufacture of these products in the United Kingdom wherever possible.

“The single-driver performance is certainly rather different from the far more widespread ‘speakers with bass’ approach. After the last couple of months experience I’ve come to the conclusion that it’s not only entirely valid, but actually a superior approach…” Paul Messenger

  • Black MA-01 full 3/4 perspective

    MA-01 Flexible amplifier ()

    I backed Stefan in his kickstarter campaign, and ordered a 6 channel tiered amp for active speaker duties. It comprises of 2x500wpc, 2x250 and 2x125 . I have owned it for 3 months now, so think I can safely say it is the best amp I have ever owned. It is neutral, and has a very clean sound, but with great authority, and the most glorious bass. As has been stated above it has some extras, for speaker protection, and if you are worried about the fans, mine have still yet to come on. It has performed faultlessly so far, and I cannot praise it enough.

    Alpair 11 MS- Gold/Grey (single driver) (£115.00 inc VAT)

    It was much fun to build the frugel horn xl kit from KJFAudio. So I thought It could be interesting to build a pair of Pensil 11 speakers with Alpair 11MS drivers from KJF Audio. Again, building the speakers was a pleasure and I was even more pleased when I listened to them. Stefan didn't exaggerate when he recommended these new drivers. They deliver great, neutral sound. The soundstage is wide and imaging is truly three dimensional. The Pensils work surprisingly well with rock music and they are just fantastic when it comes to jazz. And they look good. Although breaking-in time is supposed to be no more than 10 hours of playing light music at moderate levels, I find that the Alpair 11MS need much more time to show all their qualities. I felt that they reached another level of performance after roughly 200 hours of listening. Especially when it comes to vocal music. After the positive experience with this excellent driver in the Pensils, I grew curiosity to listen to them in a large horn enclosure. So I bought a second pair of the Alpair 11MS and Scott Lindgren's plan set for the Brodgar Horns.
    Although building Pensils and Frugel Horns from kits was quite easy, I decided to take the plan set to my carpenter friend who built the speakers with me. Lacking space, tools and skills, I know now that this was a wise decision. My respect for carpenters grew constantly during the building process of a truly beautiful pair of huge, elegant looking horns.
    I wish I could include a photo.
    Their sound is just spectacular. Compared to the Pensils, the Brodgar Horns sound more dynamic with a bigger soundstage and they give even more precise imaging along with impressive bass reproduction. Instruments as well as voices appear larger, actually they seem to be as large as live.
    The Alpair 11MS are brilliant drivers that offer tremendous value for money and work extremely well in different types of enclosures. Highly recommended!

  • Markaudio Sota Viotti white oak main product shot

    Viotti One with stands (pair) (£1,495.20 inc VAT)

    I purchased a pair of Viotti Towers from KJF Audio and I am overjoyed with my purchase. They sound sublime as well as having great WAF (very important as these are for my lounge and not the mancave :-) )
    I also had specific requirements for date and time of delivery and these were met with great precision.
    I recommend KJF Audio wholeheartedly!!!

  • Black MA-01 full 3/4 perspective

    MA-01 Flexible amplifier ()

    I ordered the MA-01 with 2 x NC250MP boards at the start of the Kickstarter campaign. Communication was excellent and it arrived safely and is exactly as described. Build quality is very good, especially for an amp at this relatively low price.
    Yes there are other companies offering a similar build with these Hypex cards but if you read the description you will see several features such as overheat protection with built in fans (no noise) and clipping indication.
    Sound quality is excellent and I have no hesitation in recommending this purchase.

  • alpair11_group shot-6508

    Alpair 11 MS- Gold/Grey (single driver) (£115.00 inc VAT)

    I really, really am digging the ms11's... they are a blast.

    They destroy many, many 2 way's with a 6,5" driver, for 80-90% of the music genre.

    They do bass really good, quick dry, with a good thump. I really don't miss a tweeter and they have a much broader soundstage then my XTZ 99.26 speakers with fully upgraded filters.

    And that is just from a 1971 speaker case with a radio shack wire as thin as my hair. Can't wait to hear them in good enclosures from a proper designer and builder :D

    Can't wait to receive the Notromo's cases, build by you!

  • soft-chrome-and-vintage-gold-pluvia-7

    Pluvia 7 – Soft Chrome/Vintage Gold (pair) (£87.50 inc VAT)

    Really nice drivers. I wasn't sure what to expect from a full range driver but I was very pleasantly surprised at the results from these.

    I used these drivers in a set of compact, sealed box speakers . The drivers are easy to install as the cut-out size is pretty close to a standard hole-saw (102mm). Rebating is optional because they are so shallow.

    During run-in the I found the sound to be quite thin, but after a couple of weeks they really improved. The bass extension is much better than I expected from a compact driver in a sealed cabinet.
    Imaging is spot on, bass is taught and fast, mids are fantastic. If I had one criticism, it would be that they can be a tiny bit harsh at the top end, although this is still improving with time and I do have some very ropey recordings. For most music, especially acoustic, they sound wonderful. I've even tried them out on some thrash metal, and while the scale isn't there, the speed and detail is spot on with just enough bass.

    These have now displaced my Quad 11L speakers in the living room. Not bad for £80 drivers, a little bit of hardware and some scrap plywood. Although I veneered them to keep the wife happy.

    I put some pictures of the build and finished speakers up here:

    I will certainly be back to try out a larger set soon...

  • Alpair 7.3 Grey/Gold (Pair) (£102.00 inc VAT)

    So normally I don't write reviews, but I have to in this particular occasion.
    First off, amazing service by Stefan from KJF audio, the delivery took bit longer than expected, but the issue was with courier and thanks a lot to Stefan for following it up.

    Anyways, about the these little Markaudio drivers. I've built a simple bookshelf enclosure for them using a design from the Markaudio site. They're placed in a close range desktop configuration, small room.

    I have been listening to them for ~10 days already and have to say - WOW ! I am no audiophile and it is my first full-range speaker, but I was blown away with how detailed these drivers can reproduce the sound across the whole range. I am actually hearing sounds in the song I was not aware of before.

    Someone in the reviews already mentioned, these little speakers especially shine in mids. Turn on some instrumental music with deep vocals. Seems like the singer is actually in front of you, just amazing. The bass is also there, bit less impressive than mids/highs, but still able to push very low taking into account speaker size.

    Tried not to overdrive them with high volume to get proper break-in. Now as I turn the volume a bit higher the sound just keep getting better.

    I give 5 stars in any case, but with a slight caveat as future customers might be interested. I believe it might be common with all full-range speakers - the drivers struggle a tiny bit with more complex music. E.g. some more intense rock songs, classical or even electronics. Could be just my opinion though.

    Overall - very happy with the purchase. Totally recommend to anyone thinking on the first DIY build, it is lot of fun and the results don't disappoint.

  • Alpair 7.3 Grey/Gold (Pair) (£102.00 inc VAT)

    A little single drive unit...
    Open the box and you might think, going to sound like a cheap transistor radio or at best a budget “hifi”
    WRONG!
    The Mark Audio Alpair 7.3’s were mounted into a FH3 enclosure and gently played in for about 160 hours. Sounding good so far...
    Now for some critical listening.
    WOW, just wow.
    I can qualify this by saying over the years, I’ve had the pleasure of sitting in front of the best. By that I mean speakers in the £3k plus bracket. I might also add, I’m a bass player, electric and double bass (I’m all about the bass).
    These drivers DO bass, effortlessly and naturally. It’s not trouser flapping bass, remember this is a sub 4 inch driver not a 15 inch sub! Nor is it booming or indistinct. Every bass line presented was sure footed, firm and articulate. No complaints here. Kicks, toms and timpani thundered too.
    And it doesn’t stop there...
    The highs are something else. Cymbals splish, splash, shimmer and sizzle, triangles tingle.
    But... they excel in the mids. These units set up a totally immersive 3D sound stage beyond the confines of the box, with depth and space you would expect from a single point source.
    And front and centre we have, well, whatever is front and centre. Nothing gets lost in the mix. The delivery and detail is astounding.
    They do voice extremely well. Vocals, piano, acoustic guitar, violin or clarinet all laid bare.
    I’ve played many benchmark reference tracks from every genre through these and nothing came up short or left me disappointed. Toes were tapping, there were smiles, goosebumps and even tears. That, is the mark of a great speaker.
    These little single drivers are up there in the all time greats!

    p.s. The 7.3’s do work exceptionally well in the FH3 cabinets. I went down the self build road but these cabinets are available in flat-pack kits. CNC machined from 18mm birch ply, they not only look gorgeous but having watched the online build tutorials, seem like a cinch to complete. A classic match.

  • Alpair 10.3 gen3 grey

    Alpair 10.3 - Grey/Gold (single driver) (£92.50 inc VAT)

    Excuse me for my English first, i’am self learner. I bought pair of this drivers 4months ago, now i decide to wrote my personal opion. After ten years of having same system, 2 and half way french stand speakers powered by classic AB class amp. I realise it’s time to make a change. First i search for options on internet, make so many price calculations, simulations in cad programs and realize when you have budget under 1000eur to build up something you can call it "high-end" and stay rock solid for this "conviction" .....it’s nearly impossible. Because under this price you must do a compromises, on crossover, on driver’s, enclosure, interconect’s etc. So after some time i told myself i must buy some audio monitor’s from recent company and forgot about DIY. Simple there is no way to do corectly for this price. I got break for a month and bug in my head just drill my brain again. I had idea, going to audio forum’s and doing research again. Find this little company called MarkAudio. At first I was worried, got only one experience with fullrange driver’s and it was not a good experience, midrange was good, but the rest of the spectrum was horrible, sound like someone put HF and LF filter on the end’s. But i was attracted to completly get out crossover, becasue you know when you mean with crossover seriously and build it up with some not so cheap foil-oil caps...it get very expensive. And it’s other factors to like loss some energy, phase shifting etc. I order pair...now i say wonderful driver’s Alpair M10 and decide to build Erich's Hartmann's bookshelf box. Second i search for amplifier, i choose Hypex AS2.100d. I apologise for tube guy’s,who like this drivers for pure analog, but my system ist all the way digital..... After saturday "merge" of amp, speaker’s and enclosure, play first song....and sit in the couch until 5am on monday. So many naunces, information, so clear and realy deep bass come flat to 30Hz ! I was shocked ! High its good enough after first hearing, but after burn up past few weeks come more birghter. It’s really complicated to wrote about sound, but for me when some one ask me for really good speakers on budget now i know what i tell. MarkAudio roll’s over everything at this price point ! So many gosebumps every day listen to new song hear it like never before :)

  • A finished Pensil 11 flat pack speaker kit

    Pensil 11 DIY speaker kit (From: £480.00 inc VAT)

    Well about 5 months ago I purchased a pair of pencil 11 full range speaker kit from Stefan, I have always wanted a pair of full range but worried that you don't get much bottom end until I got these, WOW. The kit is easy to assemble. It took about 80 to 100 hrs to run in. You can tune them to your own taste it took me about a month. The bass that comes from these drivers is amazing, the sound stage is lovely, cymbals sound like cymbals. Awesome sound. well done kjf audio....and a big thanks to Stefan for your help and advice.
