Gathering gear for this OB build.
Quick question about the DSP.
Are MiniDSP files compatible across the range. Ie. MiniDSP 2x4HD work with 4x10HD or 10x10Hd?
Or are they unit specific?

Sorry I don't know. I have bot 4x10HD and several 2x4HD units. Each has different configuration, so I haven't tried to upoad "wrong ones".
At least the software is a bit diffrent for 2x4 vs 4x10

Platform specific. I have 2X4's, my brother has a 4X10. Not the same plug in. The software is so cheap it shouldn't be an issue.
Thanks Perry.
I have another noob question in relation to your design, and multi channel Ob/dipole speakers in general. More so a question to amplification of these speakers.
Is it possible to run two different amps for the bi-amping? ie, not the same exact model/specs. One for the lower frequency, one for the upper?
Say someone wants to run a tube amp for the upper frequencies, and more powerful SS amp for the bigger woofers? Is that possible?
I presume there can be some hiccups like dealing with separate gain/volume issues exist, etc.
Whats it take to make this happen?

Thread split from the open baffle gallery thread.You certainly can! Depending on how you implement this it could be a superior solution. I do active 4-way today with a tube amp for tweeters, a tube amp for midrange, a class D for midbass, and plate amps for subs. I use Acourate software to develop the digital crossovers and correction filters. I much prefer this. It is not the only way to do it, of course, neither necessarily the "best" way for everyone. Works for me 🙂
Of course you can do this, as long as you match the levels by whatever means it will work fine.
You might find different results than you expect. Like for example I made a system which is *extremely* accurate to the point of being excessively analytical, see

They sound best with transistor amp on the tweeters and tube amp on the woofers (Yaqin 40W). I originally expected to use tubes on tweeters and Adcom amps on the woofers but it turns out tubes have too much audible distortion and the tweeters mercilessly reveal it. However with the woofers they soften the hard edges and make a more "round" pleasant sound, and you can't hear the distortion audibly as such.
(I'm under no illusion that tube amps are more accurate; they're not. But they have a different signature sound. Which sometimes is simply preferable. Cone materials - amps - DACs all have their own signature sound and you have to try stuff until you find combos that sound best.)

Hi Perry. I am glad i found this post. I was considering the beryllium dipoles you designed. I was planning on using the hypex fusion 3 channel plate amp with two channels bridged for the mid woofer and adding a sub for low frequencies.
Hearing your comment of over analytical gives me pause. The constant directivity aspect is intriguing. I haven't started collecting the drivers or making the baffle.
I am looking for a open baffle design not for supper analytical response, more along the lines of something that is great for long listening sessions. Any suggestions?
Perry's speaker has monopole tweeter in a waveguide. This means that the speaker has zero radiation on the backside of the baffle, unlike the woofer. This makes them to sound too analytical. I had this same issue...
Here is the article i read. Got me thinking i wanted to make these. When i read his comments her in those thread i took pause because it sounded like maybe these were not his dessert island two ways. You can see they're is a horn loaded compression driver on the back on the bottom of the brace. I planned on using these with a sub and passing at 60htz. I am now leaning twords doing something that's more kit style because i really have no experience with filter design. I really would like to do a active so though.
