    Again yours look superb!
    Completely understand, Greg. I'm more than happy for you to audition the LXmini (and LX521.4) at my place, but realise it is a long trek from London.

    There is an "Official LXmini Seeking Auditions" thread on the OPLUG forum where owners can offer auditions or people who would like to hear them can ask if there is anyone in their area that has LXminis.

    They look really neat Gordon, even better than you described to me, looking forward to hearing them soon.

    I was originally going to build them from scratch, but found that getting the US size Schedule40 pipe was quite expensive in the UK due to minimum length requirements. Buying the kit from MagicLX in Germany was almost the same price so I opted for that. It's a nice kit with everything cut very precisely. I decided to go with a modern hi-tech look and wrapped the white plastic with 3M carbon fibre vinyl, mimicking the woven upper driver. 3M carbon fibre vinyl is pressure sensitive, so fairly easy to position before fastening down. Micro holes help to ensure that any bubbles are easy to remove. MagicLX's spacers hold the upper drive in place, rather than the screws used in Siegfried Linkwitz's original plans and make for a neater build. They also groove the base so all driver wires are hidden. A single Neutrik SpeakON connector fits neatly into the base. Like all Linkwitz's speakers they are active so I use Canare 4S11 star quad cable.

    So, how do they sound - like all of Linkwitz's designs they major on imaging. They're an interesting design with a polar pattern that starts off in the lower frequencies as an omni, becoming cardioid through the crossover region and dipole at the top end. Useful output down to 45Hz. They can also be used with the bass modules from my LX521s to become LX Mini Studios. This frees up the small upward firing woofer, increasing dynamics and enabling them to play much louder. They are very similar tonally to the LX521.

    What Siegfried Linkwitz has done with a pair of inexpensive drivers and a couple of pieces of plastic tube is amazing. They are quite special.







    Wow

    My system may be in for a forced change soon as I've been borrowing my friends Open Baffle speakers for some time and he may want them back. Both the LX mini+2, and LX 521.4 system are options at the moment. I like the fact that numerous people have built them all over the world and the OPlug forum is full of knowledgeable people so if I get stuck I feel help would be on hand. The relative complexity i.e number of channels of amplification, wiring, dsp configuration does not appeal however and I do wonder if a simple passive Open Baffle design may get quite close on some forms of music.
    The DSP/ASP, power amp options are giving me a headache especially as I'm a bit of a tight arse. I've built some scale mock ups of the LX521.4 and they look OK in the room just about, and have partial approval from the misses but I do like the less complicated build/cost benefits of the LX minis+subs option. If I choose certain DSP /poweramp combinations I can see there is a possible upgrade path allowing to move on from the Minis to the 521's but may I ask, and I appreciate this is your subjective view, if you scored the 521's as 10/10 what would you score the LxMinis and the the Lx Minis + Subs i.e what doe the 521's bring to the party, just additional volume?
    Cheers
    Paul
