Mamged to squeeze in drilling the holes in the bracing and then fitted the deadsheet in the warmth of the lounge.  Driver fitting and temp hookup wiring tomorrow

Set about Installing the temporary wiring and drivers this morning, mounting the monitor on the LHS (older style) bass cabinet and removing the KEFs.  

All sorted now 😁

just loads of listening and testing with REW to do now but first impression is vv positive 

Of course I still have the new style bass cab to build fir the LHS and the the birch ply cladding fir all 4 cabinets too

Had time today after starting my report writing at 7am to connect up the laptop to the system and run some sweeps with REW.

First issue I found was I have a problem with the amp that runs the Fostex Supertweeters.....I’d noticed the RHS one was hardly operational....now both have stopped  🙁

I adjusted the DCX settings to allow the Scansoeak units in the new monitors to go up to 20KHz and did an initial sweep.  
 

I’ve thought since having both monitors in situ that there was more space around instruments and a better front to back soundstage too. ......the initial sweep showed a far smoother midrange curve and then with some tweaking to the dsp settings I could extend the flat portion of the midrange and interestingly the Scanspeak units were giving me far more High end response.

All good then ....and a tweak on the eq for the bass end - and increase of 5 dB aided the curve even more 😀

here is the before /after curve ....the before in this case (RED) being the KEF 104/2 speakers fir the mid bass/ midrange/HF and the purple the revised eq with the new monitors.  Even though it’s my kit/build/ ideas etc it’s a huge leap forward imho.

More to come I think as I refine things a bit more.

Started the ‘wrap’ of the monitors today ....a test build using wickes hardwood face ply 

18 mm clamped onto the 18mm mdf cabinet with m8 stainless steel cap heads

have got to do the front & rear baffles to do next which will give the edges of the ply.  Planned finish is with a cedar coloured danish oil then clear wax

Had some time today to fit some of the 18mm ply skin to the second monitor and mt ebony feet arrived today so I could test fit them

and the feet ...in a tripod config as the monitor is quite heavily loaded towards the Volt driver

Spent most of yesterday afternoon making the front baffle out of the 18mm hardwood ply and sorting the tee nut fixings for the mid bass and midrange drivers

six m8 bolts holding the front baffle

next step is a 45 deg chamfer in the edges of the front baffle
