    Low distortion drivers for sub-bass in shallow sealed cabinets

    I would also add that - at least according to my experience - the room will actually play a bigger role in terms of distortion than your speaker drivers.... I have seen rooms where a null-point induced distortion reached 5-10% in the range of 40-80Hz I fully agree with @sigbergaudio that you...

    Fail with Maop 11.2 matched pair

    To be honest I would struggle to provide the 'best' answer since there are so many variables here... One thing is for sure: getting all your speakers on a separate channel (any of these shall work for that purpose) and measuring/setting correct delay values (along with proper lowpass and...

    Low distortion drivers for sub-bass in shallow sealed cabinets

    I was trying to find the T/S parameters for the Redcatt SW10.4 PC but could not find them Can you please share where you managed to find them? While I was browsing their driver portfolio I noticed that they publish peak-to-peak xmax values - be careful with that, you actually have to divide...

    Low distortion drivers for sub-bass in shallow sealed cabinets

    You are welcome :) I love this brand, for my last three sub projects I used their drivers and they are superb!

    Low distortion drivers for sub-bass in shallow sealed cabinets

    Yes, typical PA woofer but I dared recommend it since you said you would use heavy DSP - and with that I guess it should work fine Cost is similar, 227 EUR. The safe(r) bet would be the SB though I am not aware of any distortion measurements for these drivers :(

    Actually not that expensive: This is from toutlehautparleur.com (I order all my drivers from them)

    Passive system using the 15” SB42FHCL75-6 Bass driver

    Just for fun I played around with simulating this driver If you put it in a sealed box of 46 liters you can drive it to xmax with 750Wand that will give you 103.4dB at 20Hz at 1 meter This will cost you about 400 EUR Alternatively you can buy two Lavoce SSF153.00 drivers and put both of...

    Dirac Live Exclamation Mark issue

    I have had some time to play around with the UMIK-2, you can see my general experience described here: https://audiosciencereview.com/forum/index.php?threads/using-four-bass-guitar-drivers-to-build-a-dual-opposed-subwoofer-project.56479/ When it comes to using it with Dirac Live 3.10.3...

    Setting subwoofer delay

    So finally today I got my UMIK-2: Visually, the difference vs UMIK-1 is the colour and the capsule that looks totally different It is no longer fully Plug & Play (at least in Windows), meaning that you have to install a driver for it to work properly. Also there is a firmware update...

    Adding a third sub to cancel "Deep Mid-Bass Null"

    I am really curious to see if this will work out well I have tried it in the past but for me there was a constant clock drift issue (i.e. the delay kept changing all the time) even when using two identical DACs Hence I have an RME Digiface in my home office system and a miniDSP UDIO-8 in my main...

    Fail with Maop 11.2 matched pair

    Unfortunately I have no experience whatsoever with macOS (I use Win11) so I will let the more experienced fellow members here comment on the DSP front But it sounds like a good way forward to me!

    Dirac Live Exclamation Mark issue

    Some fresh updates: - I just got an email today from Dirac that in 1-2 months' time there shall be an update released that will solve all the remaining issues (they have promised that like 4 times already but let's be optimistic). They have a new CEO so things might indeed take a turn for...

    Adding a third sub to cancel "Deep Mid-Bass Null"

    You are right @Keith_W I was also playing around with it and came to this conclusion: I don't think there is a need for a 3rd sub here
