  1. Interesting - not sure I have seen, but where are your subs positioned? Along with the Kii's facing forward, or somewhere else? Kii noted in one of the discussions that they prefer x-over at 30Hz and with subs facing forward alongside Kii's so they notionally contribute to the Cardiod distribution and don;t drive refelections off rear/side walls etc. (not sure that stands up in practice - but is what they suggested) At risk of getting off topic, the SHD Studio is, as picked up here, multiple devices in one. Powerful DSP, Digital Preamp and Dirac Live processor with overlay o
  2. Thats pretty close. After reading through as much as I could find on the Kii's I took the approach (right or wrong) of trying to protect the Kii cardiod distribution while shifting some of the low frequency load from Kii to Sub to free up the Kii's bottom end SPL limit. Free from the @Snoopy8 constraint of protecting DSD, it was easy to use the miniDSP for preset x-overs at 30, 50 and 80 Hz using LPF for sub and matching HPF for Kii's. For normal listening I use 30Hz with a Dirac curve that just irons out the bottom end bumps (below 200Hz). For a louder, heavier bass fix I use 50Hz with 2d
  3. Interested to know if MSO calculated the delay from scratch, you did it through measurements, of you set 90ms and let MSO tidy up? I did my best to measure it using REW, set that in OpenDRC, and left Dirac to tidy up (if it actually does?). But have read lots on why measuring sub delay is full of problems given the low wavelength and difficulty in seeing an impulse response.
  4. With the Kii's and Dirac I found no value / upside in optimising above 200Hz - if anything going higher made things worse. Great work @Snoopy8 - maintaining DSD a good outcome. MSO looks interesting, and the Behringer DCX2496 is something I hadn't found. One of the few devices with a delay big enough to handle the Kii's latency - can you fix/bypass its volume so it can't be changed? Good alternative to the no longer supported miniDSP OpenDRC.
  5. Just noticed a new firmware release for Kii Control as of 19 March - anyone tried it? Seems to be mainly about simplifying the Menu structure, but I haven;t tried it or got my head around the changes outlined. Gibbo
  6. I didn't get through the full Youtube video but he may well touch on this. Unfortunately there are so many pressings of Rumours that it becomes really hard to ensure you secure a good pressing. When I went looking for a 'good' 45 RPM pressing to update from my well worn original it seemed the Pallas pressed, Hoffman/Grey version is well regarded. But it is damn hard to work out you have the right copy. The labels on the vinyl itself and the cover artwork say Pressed in EU - so nothing useful in distinguishing. After much reading it seems the Pallas version is forensically determined by:

  8. Good idea. To me Dirac is complicated enough when done well so perhaps keep focussed. Quite a bit in one of the NAD discussions as well from what I recall. Here we will keep trying to understand where 'punch' comes from!
  9. Very useful reminder and graphic It is pretty well documented that the combination of small, sealed cabinet and 4 long throw drivers partially out of phase really chews power in the Kii's and they will begin to power limit around 85db despite 250 W per driver. In DSP mode it is also about how they manage impulse response rather than steady frequency reproduction, plus the whole cardiod theory. Will do some testing around the 150Hz 'punch' theory. I do remember when setting up sub at 80 Hz crossover or lower, I ran Dirac boost of 4db up to around 300Hz to get a soun
  10. Looks like a pair would be a great stands on which to put <insert Kii, D&D, Bucahrdt etc. . . . . >
  11. Point taken - but not quite what I was getting at. @Ray H touched on the issue above. What is the source of the 'punch'? Why might one be 'dry'? Does a 75db 25Hz transient signal sound the same if coming from multiple smaller drivers facing different ways, versus a single large driver? Can one have 'punch' and not the other given sound waves at that frequency aren't directional? Or is the 'punch' coming from a higher SPL / more bass tilted frequency response (set in design of passives, in theory under control of the DSP in actives)?
  12. We are touching on it - so lets draw out the impact of the chosen 'house' or standard curve the active speaker manufacturers set as their default, what we hear as differences, and what are the limitations to changing it? Some thoughts from my playing. Kii's out the box measure pretty much flat down to 25Hz but certainly don't have the punch / gravitas / air movement my old 15 inch Tannoy's had. So I set up a Dirac curve that mirrored this 'house' Kii curve but extended flat to 15Hz, and applied that with no sub, and with sub crossover at 30, 50 and 80Hz. I guess I mentally expec
  13. My intent with this thread was to drive some constructive, thoughtful and hopefully hands on comparisons that can help us all make better informed decisions for our needs. Genelec's sound very competent - but WAF wouldn't let them through the front door here!! All views welcome, but please give us a little more on the basis for your comments. For example, not sure there is much doubt that some of the Genelecs peak at higher SPL than many of the home audio oriented speakers. Some may value that. Equally, the specs of some of these speakers in terms of frequency response don't seem to a
