This topic is meant to share DSP Configuration Files we as users of the Orelino / Orelo MKII Loudspeakers found for certain "applications".
I can be concidered one of these users and of course I created a "best base" configuration the speakers will be shipped with. However, all this means is that the DSP firmware in the speaker is loaded with this base configuration, ready for you to change if you want. But wat you actually change is the configuration file by means of a PC program and you upload that configuration to the speaker (different per Left / Right channel if you want).Applications
First off, an application can *not* be about room corrections. That is, this is obviously nothing to share amongst us because if we apply room corrections this will be dedicated to our specific rooms and it won't work out in others.
Advice anyway : Try to avoid room corrections because only in very rare cases it will be necessary. But also : If we start trying the settings of others, it will not be convenient to
a. share any configuration because first the room corrections must be taken out;
b. load any shared configuration and try it because we would need to apply our own room correction first.
One of the applications could be the way the bass-mid crossover is set up; Imagine a "slope" coming down from the mid and how you can let ride the slope of the bass against that; officially there is one good way for that only, but with some experience more ways exist if first the slope of the mid has been made for that; Notice this is too detailed to work out in this post, but also notice that the forum board is OK for this when needed. Anyway, the one means to do this works better than the other, and all is about thevery best way the crossover works, which is as we know crucial.
A very different application would be about the balance between wanted SPL and the lowest frequency to support for that SPL. For example, while the Orelo MKII's standard configuration has been made to go deliver a straight to 19Hz (+/- 0.5dB) this is related to the reference level which is 88dBSPL. Now, 88dBSPL is more than enough for everybody with the larger room and normal usage and where talking will be difficult. Still, we audio freaks may want a crazy 100dBSPL with undistorted sound. Now if that freak also likes to play music containing those very low frequencies (because the music just contains that in the more rate cases), it can be a better solution to change the "straight to 19Hz" into e.g. "straight to 23Hz".
So just envision the downward going line at 19Hz to be at 23Hz and all further being the same. One difference : the speaker will now play (audibly) distortion-free at 100dBSPL (that assumed - I just took a figure).
While the example of "100dBSPL" possibly is not very realistic, the other way around can very well be : Create a response for e.g. 85dBSPL and let go the speaker straight to 17Hz.
This *is* realistic, because my tuned reference level of 88dBSPL the speaker is shipped with, is for my larger room - and any way smaller room will never utilize 88dBSPL (it will be too loud).
An application - though a strange one - in the same direction could be "movies"; Movies tend to show sub low, but what we will not be used to much is that this sub low actually is inaudible. So really, any 19Hz can not be heard. Still we are used to hearing it because our beautiful subwoofers distort so heavily that it just will be audible as distortion, never mind we don't notice that per se, and it is about the effect. And so, for example, the roll off could be made at 17Hz instead of the 19Hz as you see in the plot above and the movie putting out that 17Hz while say the level played is still 88dBSPL will now nicely "shake" the room. All what happens is that now maybe 1cm (peak peak) excursion occurs and while nothing will break yet, your 17Hz will be there (in distorted fashion and just like you are used to).
But of course we don't like this to happen with our music; there any 17Hz if present should pass by without even knowing that it's there (meaning : cut off at 19Hz when you play at 88dBSPL).
Another application is again in the XOver area, but now its "technical DSP". What I mean is that the offered various types of filters imply different (also cascaded) processing in the DSP (btw Digital Sound Processor). Now I don't like to turn it into XXHighEnd facilities, but in the end it is a kind of so;
We can well say that a more lean filter (less filtering means applied) sounds better. Also, the one type of filter just *is* more lean than the other, but obviously has a different target. Still it could do the job we hunt for, like "create that slope needed". And so as we say, more routes lead to Rome.
Lastly on this, people who obtain the Orelino will see that all said above sort of multiplies because the Orelino's specs on the low end are obviously somewhat less than the Orelo MKII. For example, I use the Orelino with a slow roll off from 25Hz so it turns up at -9dB at 18Hz with a reference level of 86dBSPL. In practice this means that there's now all kind of variations possible from letting it steeply roll of at 25Hz so a way higher SPL is allowed, via a slow roll of from 25Hz to e.g. 23Hz and let it steeply roll off from there and still allow for way higher SPL - through ... etc. etc. etc.
Of course, once you like to go working on your DSP filters you will need some ADC means, some (free) software and a measurement microphone; Once you have that (if at all) you will see that it needs quite some experience to get all where you want. But this too is what this forum board is for and I am there to help.
In the end, no worries; I too will be experimenting further and while I already have a few options ready for you, more are bound to come from my side already;
All together I'm sure that an already great speaker will be even more great just because of these software upgrades and because again your ear count will be more than mine alone. So what also is allowed
is that you just ask for something like "hey, I want more bass". Well, since I can do that fairly easy I can make you such a config and upload it to here and you can try it out. But meanwhile I will tell what I did, how it looks (plot of the DSP response) and you will learn leasily how to do such a thing yourself in a responsible way.
I will add the first base configuration(s) when the first speakers arrive at customers and this will be soon.
