Who are we?

We are a small business specialising in DIY home audio speakers, full range speaker kits, speaker cabinet flat packs and custom speaker design. We are the official UK/EU Markaudio and Hypex distributor. 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

  • Stereo to mono Hypex Nilai 500 conversion kit cables and adapter plate

    Hypex Nilai Stereo to dual mono adapter kit (£75.00 UK VAT added in cart)

    Thank you very much for this adaptor kit. I received it promptly together with an additional power supply. It was no problem fitting the plate with the power supplies and connecting the cable kit included with the adaptor plate. The job took less than 1 hour. The difference in sound was immediately obvious. A bigger soundstage and better separation of sounds. The sound is now more relaxed and plays better at low volumes. This kit makes that change from stereo to dual mono very easy and the change is at least in my case worthwhile.

  • Pluvia 7 PHD markaudio

    Pluvia 7 PHD (pair) (£75.00 UK VAT added in cart)

    Bought as drop in replacements for some 7ms transmission lines that had unfortunately been poked by children, these suit my taste much more. I guess the slight reduction in high treble makes them sound richer. I was worried by the drop but wanted paper cones, I really shouldn't have been there's still plenty of highs

  • Markaudio CHP 90

    CHP 90 (Pair) (£100.00 UK VAT added in cart)

    This is one of my favorite drivers from Markaudio.
    I have built the Bluebuck box which I think gives a good base.
    Lots of detail from these drivers. Paper cone with "Mica".
    Very nice sound of midrange and treble. You can see the "music" in front of you.
    Everything fades out even outside the speakers.
    The scenario is wide, high and deep.
    I recommend the Bluebuck box for these drivers.
    Good luck!

  • CHN-110 (single driver) (£45.83 UK VAT added in cart)

    SUMMARY:
    Very good reasonable priced driver, easy implementation and good sensitivity, covers almost all audio range.
    Good for replacing of old speakers or DIY build.

    DETAILED:
    Here is my implementation of CHN-110 drivers into the cabinets from Seas Loki DIY speakers kit.

    The Seas Loki kit based on 6.5" Seas coaxial driver in 12L vented box, old design but still available today.
    Since my kit was purchased about 15 years ago, it's drivers were worn out a bit and suspension glue started detach.
    But cabinets by itself are still looks as new (except grill cloth), so I decided not to repair/replace drivers but to try something other like full-ranges.
    They should be suitable to my box volume and fit to existing baffle opening.
    That's why CHN-110 by MarkAudio.
    It fit very good in my baffle opening.
    Actually, I was need only to make a new sealing gasket and remove crossover. Zero woodworking!

    After a short burn-in, about 10 hours or so, did some first measurements.
    In lack of a specialized acoustic tools, I just used my portable recorder Zoom H1 to capture played noise then puts it to software analyze.
    Got results with very good mating to what I can hear by my own ears, or can calculate for my small working room.
    Will continue burn-in together with background listening, then will re-take graphs and compare.
    Also need to find new cloth for grilles. On photo, the grill got some violet tint, but in reality it is black, just lost it's initial look.

    First sonic impressions - good-positive.
    Speakers was placed on table close to the wall and corner, directed to listen point.
    Room was small, busy of various things and no acoustic treatment at all.
    So, no chances for perfect sound. But.
    Lows are surprisingly full but not booming.
    Mids are smooth.
    High area is not annoying at all.
    Good impact, details.
    Excellent imaging, sounds don't come "from the box".
    Don't feel wishes to switch off after a 1-2 hours of listening at low-to-moderate levels. (For me, bad speaker can take 10-15 min max of my time)

    Can't find a way to attach photos...

  • CHR 90 Group 800x600

    CHR 90 - Gold/Grey (Pair) (£100.00 UK VAT added in cart)

    I have just completed a home build with a 14 litre cabinet, ported with 35mm ports and the CHR 90's supplied by KJF. First impressions are quite simply superb. As I hoped, home building with care and taking your time to research the best materials (in this case, heavily braced 12mm ply, but factoring in the bracing volume first to maintain that 14 litre cabinet volume) seems to have worked wonders. So looking forward to breaking them in properly and just enjoying the life-like reproduction. Many thanks Markaudio and Stefan at KJF.

  • Hypex Nilai500DIY Mono Kit - Front View

    Hypex Nilai500DIY 500W Mono Kit (£690.00 UK VAT added in cart)

    I’ve had my Nilai monos for just over a year now so I thought perhaps time to give some feedback. First, the buying experience. If you feel nervous about dealing with a small business like KJF, don’t be. Stefan was a pleasure to deal with (and he has a dry sense of humour!). He very readily got back to Hypex on a small post-sale issue, which was in fact caused by my home crafted power lead. Now, making the kits. It really was easy. Just take it steady, follow the visual instructions and you get there. No soldering required. It helps to slacken off the casing screws slightly when sliding the lid panel into place, but that’s all I can really add here. The casework is a series of panels which fit precisely - very precisely! - together. Serviceable rather than beautiful, the finished unit has a distinct sense of solidity. How does they sound? I would use terms like ‘quick', ‘detailed’, ‘open’, ‘non-fatiguing’. But I’m not sure how much that helps anyone else. The fact is I don’t really notice them now. I just listen to the music. So if these Hypex Nilai500s have a ‘sound’, I really, really like it. Any criticisms? The standby button is tiny, invisible on the casework and I have to locate it by feel. A circular, edge illuminated switch like my RME DAC would have been preferable. That’s it. Otherwise, these are really great pieces of kit.

  • SA-01-out of stock

    SA-01 Stereo Power amplifier (250W) (£590.00 UK VAT added in cart)

    I was sceptical that a class D amp would suit my system and musical preferences so to cut to the chase - SA-01 amp installed and running with some speakers that had sat unused for at least 12 yrs !! Unsurprisingly it took a good couple of hours for the the speakers to ' wake up ' and the new amp and cables to get their mojo going ,
    This is without doubt the quietest amp I have experienced -absolutely ink black nothingness and absolutely neutral in character , this made low level listening a real pleasure and captured a lot of musical nuances I had missed ! The speakers still need a bit more of a workout and final positioning etc - the SA-01 so far has been a total delight , great value for money and strongly recommended .
    I cannot fault Stefan and his level of service ,

    Thanks Stefan

  • Markaudio Sota Tozzi 2 - silver

    Tozzi Two (pair) ( £352.45 UK VAT added in cart)

    The Tozzi Two are a fantastic pair of speakers with a neutral transparent sound that is musical, engaging and tonally accurate. These were selected for their flat frequency response and low mass single-driver-single-suspension concept and do not disappoint. The shallow cone profile and symmetrical waveguide allow natural imaging and a wide sound dispersion. The aluminium-ABS enclosure is high quality, very rigid and has reassuring weight to it. Gold-plated banana plug contacts at the back is great, along with a bass port to slightly increase bass extension. Bass extension is respectable but limited. However, these could be blended with a pair of bass woofers such as the CHR-120 (which have a similar cone profile) with simple crossovers to produce an incredible full-bandwidth system.

    My pair cost £410 altogether; I was so impressed that I bought a second pair. Applicable for both musical enjoyment and critical listening; I use Graham Slee Proprius monoblocks for speaker amplification and the result is professional studio-standard sound for nearfield desktop listening, in my opinion. Thank you Mark Fenlon for producing this product at an affordable price point.

  • Hypex Nilai500DIY Mono Kit - Front View

    Hypex Nilai500DIY 500W Mono Kit (£690.00 UK VAT added in cart)

    The kit is very simple, anyone with some common sense can put these kits together! It is a few months now since I put mine together and I have to say I'm very happy with the mono-blocks. Initially I had a slight hum problem because I was running the pre-amp section of my integrated valve amp, using unbalanced adaptor cables. The Nilai's still sounded excellent and didn't take too long to "run in". I then managed to get a valve pre-amp with balanced outputs; hum problem solved but the pre-amp now had to be run in. The combination now sounds pretty stunning I think. Plenty of power on tap, black backgrounds and sweet (But not sugary!)highs, clean and well defined low end. Midrange is detailed, acurate (Timbre) and agile. Brass sounds like brass and strings - cello, violin and guitar - are pure and realistic (If the recording is up to it!). These kits are not cheap, but I think they still represent a clear bargain. The rest of the system is; Auralic Aries G1, Oppo udp 205 (Mainly used as a DAC, but also for disc spinning.) Pro-Ject Pre-amp RS (New old stock), Hypex Nilai 500's and Audiophysic Spark III speakers. All power is routed through a Puritan psm156 (DC blocker). Thoroughly recommended. KJF audio was spot on for service and a pleasure to deal with!
