Ceasar did you get a chance to give the software a go?
So anyways I have the impedance of the enclosure with the two woofers hooked up in series to get an 8ohm load. So far the enclosure looks good and free of crazy resonances. I still have very little direction as to the use of vituix but I’m getting ready to take some FRD measurements on rew to design a crossover. I’ll be making one in xsim and vituix to see what’s up.
My biggest desire about using vituix is that someone told me that the acoustic offset was to be calculated and implemented by the software without me doing anything, I also imagined that with the use of all of those other measurements at different angles that one could make a better x-over. But alas nothing from this forum yet, to reddit I go.
What sort of amplifier would you use ? more importantly how would you wire things up and set it up to split up the signal to have 3 channels ? I have no idea how to do such a thing, lmk if you find out how to.
So I have them built, sanded, primed, painted, and gloss finish applied. Also have fitted the interior with denim sheets for standing wave insulation. I have to actually change one of the TCP115 drivers because upon inspection of its ts parameters with DATSv3 the TCP in question is vastly different than the other. But for now this is where I’m at team.
Any news of the use of vituix cad anyone ? @Toids_DIY_Audio ? Could be a worthy vid on YT… Maybe a lil tutorial
Thank you Ceasar, I really hope this gets attention… The community needs to release a tutorial If not I will try to make one but the only problem is I don’t know how to use it at all.
These are speakers I’m currently building to test out VituixCAD2 for myself. They are a set of 2 way speakers using an MTM configuration with TCP115-4 in series to get 8ohm load with a ND25W-4. They are ported with dual PVC ports (flared on both ends). Yes I have accounted for all the volume the ports and speakers and bracing takes up.
How does one even do baffle step compensation ? And you’re probably correct, these were the first speakers I made, though its a shame they were not aligned properly, I really did try to match the curves in xsim when I was adding offset to the drivers to align them with the parallel wired measurement.
That’s very interesting, I would have guessed it was multiple ports… Do you have any explanation as to why the bracing doesn’t end up creating multiple ports ? I guess, how can we call it 1 when it was sectioned off by the bracing ? Because now I wont know when to say a rectangular port is just braced or if its multiple next to one another
Yea I forgot to post the final measurements. They were very much spot on, they’ll be attached here. But yes I haven’t delved into doing doing crazy complicated corrections, when I design my speakers I actually use these excel spreadsheets created by Marius from AudioJudgement on youtube, I believe one of them does correction for the nearfield measurements but I haven’t done else, there aren’t enough tutorials easy to follow (as a video) that I have found yet.
One thing I’m a little worried about is designing for speakers with multiple drivers of the same type. Say a center channel with two woofers or a regular bookshelf with 2 woofers or even two ports. Finding the offset I know how to do, is the process the same when it comes to multiple woofers? Just add or subtract offset until the system FRD matches the FRD of the drivers in parallel ? What about when creating a full frequency response when there’s 2 ports or more ? I personally planned on having to ports for the center channel. I don’t have any designs as of this moment though.
Is this considered to have 1 port or 4? When measuring it, do we measure each port individually or just measure one and add 6db for every port ?
