miniDSP flex and flex eight is about as "affordable" as it gets for DSP multi-ways atm. Mines been awesome.
multiple driver might take a while, these drivers aint cheap.
lars any hints on the tweeter , im like a cat on a hot tin roof

I just want a DSP plate amp that's, like, $100. It doesn't have to be great! It just has to be better than hiding a topping amp inside or making my own out of a raspberry pi and an ICEpower module. I really don't want to put an SD card in my nearfield monitors, guys.
Equalised sealed is easy as 1, 2, 3 since 1993.
Phase/group delay corrected, down to the lowest possible frequencies, on the other jand, needs some computational horsepower.
Any modern PC can do it but until someone cracks the code for easy-to-use it will have a limited audience.
I have a miniDSP Flex 8 + 6 channel NC400 + 3 way active system. It might seem expensive.
That is, until you visit a dealer and the top of the line speaker is almost 6 figures. We’re talking serious cabinet jewellery from Sonus Faber or B&W or KEF or (insert other loudspeaker model whose cabinet looks like its a 2 man lift, has been through a wind tunnel for design and has endangered timbers polished to a deep lustre)
For $100 options I see are: A couple of TPA3116 or TPA3255 based stereo amps, and using your recently retired/refurbished PC/laptop, a multichannel audio interface and software.
Or what about the Arylic Up2Stream 2.1?
Is the speaker designer/maker market is far too small for a plate amp with programmable DSP for $100?

surely hypex fusions are due for an update with the new ncorex - and with that a DSP upgrade too
Is it only me thinking hypex will never again venture into that space again? Dsp/software specifically. Remember the thread about the then new plate amps and what a mess it was. At least to me it seemed like it 🙂.
Think it would be best if Lars and minidsp sat down and discussed some cooperation 🙂.
Purifi since they have amps should offer a dsp with streamer make a bundle and better integration. basically something better than a bluesoud note but in a diy way so OEM can also adopt
I feel like, for all the reasons stated on this page, Hypex doesn't need to revamp the FA line. If they can keep selling the top of the line all-in-one at a steadily increasing price, why stop? I can only see them getting bigger, whereas I'm hoping for an FA52 with a tweeter amp that can't tear a voicecoil. I once tried asking Platin for a sample of their hardware-- the company that provides hardware for Buchardt's active lineup. They don't have a software interface for the likes of us.
Edit: For the record, there was a minidsp ICEpower plate amp that performed less than stellar according to third parties. Supposedly no headroom and high distortion, which is a shame. I'm tempted to build a set with their 2x50 bridgeable amp and a minidsp DIY kit. Still comes out to $450 plus headache. And I only get to make a pair of two-ways!

Better than Hypex? Choice of kimmosto for Taipuu actives

They’re OEM only unfortunately.
You can PM me for pricing.
Lars has a background in all digital amp. I think he will roll his own. A Purifi all-in-one, programmable DSP front end, multichannel purifi class-d backend, with all signals in digital domain, and driving a stack of Purifi tweeter/mid/woofer speaker.
OMG, world domination.
What is an “all digital amp” and what does “all signals in digital domain” mean?
Never mind, I just found this over at Audio Science Review”:
”Conclusions
The pedigree of the company and very nice industrial design got me in a very positive mood for this review. The initial DAC measurements brought my excitement level down a notch but I still held on hope for a positive outcome.
Then came the power amplifier and all of that went out the window. Tons of ultrasonic noise makes a mockery of trying to play any high-resolution content with levels of noise that would dwarf anything real music would have. Frequency response variations as early as 20 Hz show very high speaker load dependency. There is a reason every engineer designing a switching amplifier tries to get the frequency up as much as they can. We have designs from a few hundred kilohertz to even a megahertz or two.Yet it appears that Lyngdorf has opted for something close to 50 kHz. That is just too low.
EDIT: as noted in the review now, the extra noise below 100 kHz is from noise shaping. The actually switching frequency is indeed much higher and competitive with other designs.
Yes, from pure audibility point of view, the huge amount of power will be a more audible benefit than ultrasonic noise takes away. Here though, we like to see excellence in design and I don't see that in Equibit amplifier technology. It may have been fine decades back when Lyngdorf first designed it but it simply is not competitive today. You can't have an amplifier that has so much noise that it can't properly be even measured with industry standard analyzer!”
What a missed opportunity to impress with one-of-a-kind device with ideal feature list.

@mainframe99 another one to add to the DIY list on the front page.

https://sites.google.com/site/undefinition/bookshelf-speakers/virageHi I’m new to diy and looking into some ideas
I currently have a pair of active 2 ways using a sb acoustics 6” mid and tw29 tweeter
Was thinking of diying something active for myself and the Purifi amps and drivers look great
Has anyone got a design or idea for a Purifi 8” 2way with something like the sb tw29bnwg tweeter ?

Another one of Paul Carmody's designs without a single off axis measurement. Maybe good enough for 1990, but obsolete approach in 2023.
You can find off axis measurements of the non-B version of the tweeter @ hificompas:
https://hificompass.com/en/speakers/measurements/satori/satori-tw29r
As you can see, it performs on part with other ring-style tweeters. That is to say, a significant fall-off trough in the upper treble, that moves to lower with an increase in off axis measurements.
It would be nice to see a power and DI plot for this speaker. One hopes that he took into account these parameters. I like some of his earlier designs... well balanced, smooth.
If I was going to offer a public domain open-source design, I would make available both the simulations and the final measured results.
You are on the right track, this is a concept that has some potential. I recently made some measurements of my TW29BNWG, and I estimate it could be used down to ~ 1.5k. I think to get the most out of the Purifi 8" driver, you should be looking at a 1.2 k crossover. I think the Satori waveguide is a bit on the small side to match up with a high end 8" driver. I would look into an 8" waveguide using either the Satori TW29BN or the Bliesma T34B. Or wait for @augerpro to finalize the waveguide designs for the TW29TXN-B tweeter. Overall, I think the Purifi 8" driver is just perfect for mating up with a larger 8" waveguide.
