I’m using a full active horn speaker, the problem: you need a multi-way crossover with DSP as a preamp with different inputs for analogue and the different digital types.

My question is, which projects/devices can handle this job?

I only know: Trinnov, Accourate, Lyngdorf, miniDSP (not my taste),

Actually I’m using the „old“ Waf Audio DIY project.

Maybe you know some other devices?! Which multi-way DSP do you prefer?

DEQX would definitely be a contender if you are going for a DSP based solution.

Why don't you look into one of the pro loudspeaker management platforms. They certainly have the flexibility to get the job done. Such as BSS Audio. They use them to run the M2 as an example. Should be more than enough processing power.

You can use Prism Sound multi channel Dacs that allow you to use software( Pure Vinyl) that have AU plug in's to equalize each channel on the Prism Sound Dac.

Because these platforms are often not good for HiFi. For example, I need a remote control for volume, input, on/off, and so on.

They can be driven from your preamp/ processor like any other active crossover ao what you are saying doesn't make sense.

The DEQX units are very nice, particularly if you want integrated (digital) preamp functionality. They have three primary functions: (1) speaker driver correction, (2) crossover implementation (including time aligning drivers), and (3) parametric equalization. IME they were superb at the first two and just ok at #3. In the end I did not use #1, but did find the measurement that goes into creating correction filters for #1 very helpful in establishing crossover points and slopes.

Never heard one sound good. Stay passive, at least till 100 Hz with horns. For DSP best are cone speakers with subs

And what’s about time alignment? So my horn driver and Bass driver have a distance of perhaps 55cm.
DEQX units nail time alignment

IME neither active or passive is the “clear winner”. Bad passive is bad, bad active is bad, and good passive or active can be very good. When done ”right” they are more different than they are better/worse - and neither is even remotely easy to “do right”!

never heard a good active horn (only bass section below 100 seems to work). Not arguing there aren't badly done passive horns but there are good ones too

How were they configured?? I have done analog active with passive CD compensation and it sounded fine. Have never tried a full-up digital DSP compensation but I don't understand why it couldn't sound good?

Hello HornJunkie,

i use around 20 years DSP crossovers with magnetotatic speaker systems and will give you some information. Hope can help you little bit.

1. STANDALONE dsp-crossover with Master Volumecontrol 2x4 way

I think this new dspNexus from DANVILLE SIGNAL now the best Standalone product on the market.
Price around USD 3.000,-

https://danvillesignal.com/dspnexus-dsp-audio-processor

dedafb33138128052317f17cfb70a881-710px.png


This crossover using WEAVER AUDO software for programming all the crossover function like delay, high,low,bandpass- filters, etc, etc.
It is a very flexibel modul system, ..with realtime listening control if you change parameters.

Video how WEAVER AUDIO software work and programming



A other option for a good DSP Standalone crossover is maybe this from the Australia company ANALOG pRECISION. I personal not like this company because they are very unriendly to me if i ask some technical questions like, ....What are the real DSP process resolution? ...How many DAC Chips you use for the 8 output channels? ...i also asking critical questions about there technical specification they give on the homepage, etc. They don`t like my questions. But i will show you this product, maybe you like it, because have many analog Input option inkl. phono. I`m not sure how good the product from ANALOG PRECISION really is.





2. DSP CROSOVER using a PC for DSP processing + Windows crossover software + Multichannel Soundcard with master-volume-control

a) You need a fast Audio PC - optimized for Audio for Highend.

b) You install a player software like JRIVER etc. and a good multichannel crossover software on the PC like:

- DEPHONICA (great value for money) https://dephonica.comekio
or
- EKIO http://www.lupisoft.com/ekio/



c) You need a very good 8-cannel USB-DAC with master volume-control like one of this:

- OKTORESEARCH DAC 8 PRO (great value for the money) https://www.oktoresearch.com/dac8pro.htm

Review and measurements OKTO DAC 8 PRO: https://www.audiosciencereview.com/...d-measurements-of-okto-dac8-8ch-dac-amp.7064/

dac8pro_m.jpg

or

- EXASOUND E68
https://www.exasound.com/Products/e688-channelDAC.aspx

e68-Side-800.png

or

- ACKOLAPS ---- High quality 8-cannel DAC with I2S and USB Input.

taipan-8ch-combo_2_orig.png

dac-remote_1_orig.png


......there give much more like from Merging, RME, etc, etc, i show only some with good sounding and with master-volume-control.



3. Windows PC for DSP processing, with 8-channel I2S PCIe digital output card + 4 Stereo R2R DAC boards with I2S Input + master-volume-controls

This option is very nice and very good quality, if you have a little bit electronic DIY know how, ...or you have a friend who help you.

You need this parts:

a) fast good Audio optimized PC ( same like in point 2 )

b) this high quality PINK FAUN PCIe card, with 8 channel I2S digital outputs on 4 HDMI connectors.


c) Windows crossover software DEPHONICA or EKIO
(same like in point 2)

- DEPHONICA (great value for money) https://dephonica.comekio
or
- EKIO http://www.lupisoft.com/ekio/


d) 4 pieces of SOEKRIS DAM1021 Stereo R2R DAC boards with I2S Input

board_with_parts.jpg

Info: You can make master-volume-controls for all 4 DAC boards very easy, with using a 4-way 10k potentiometer, ...connect 1-way from the potentiometer with every board. The Audiosignal run NOT over the pot, Potentiometer is only the reference resistor for the digital output volume control on the board.

TB269racXXXXXakXpXXXXXXXXXX-17455497.jpg

Use a 4-way Potentiometer 10k without or with motor for remote control.. https://www.aaranis.com/index.php?main_page=product_info&products_id=395045

s-l300.jpg


In the next 2 infolinks you can see and find more information about, how to make a volume control with this Soekris R2R DAC board, ....what power supply this board need, etc., etc. ......

https://th.aliexpress.com/item/32911158189.html



Soundsample with using this SOEKRIS R2R DAC board only as a bridge for 2x4way active system. Good sounding system from a friend in Bangkok. He use for the high an mid tube amps and digital amps for the low and woofer. Open baffle speaker system for low price, but sound good with active crossover.




Best regards
Chris

PS: I`m not a friend from DEQX. Why? In my opinion the value for money is not the best and you lose to much dynamic with DEQX.
I listening one time system with DEQX. Sorry, i not like.

Add. Picture from my old system with "Fischer Antheus" speakers with 4 inside 12inch Iophon PLS320 subwoofer and FOSTEX Magnetostatic speakers. With 2x4 way active DSP crossover system from TACT AUDIO and a CD-Drive from AUDIOMECA. This system is from 2004.
Now i`m planning to make a new system.
