I'm looking for a very simple DSP crossover. I have found trigaudio and I am negotiating with them. They normally sell in MOQ 300, and I need maximum 20 (for reselling in my small DIY shop).
Are there any other alternatives. I'm not looking for a MiniDSP competitor, but just a very basic board.

best option is a board with ADAU1701. depending on other options like power-on click supppression, wide range supply input regulation, connectors, monitoring , volume control, cost will go up. cost of real time parameter change is 80$, or off line programming using an arduino. checkout freedsp board...
the cost problem is in the software. Analog devices does not allow the sale of their products and freeware software and have the end-user reprogram the DSP. That's why minidsp had to develop their own software . I estimate the board material cost below $30 in quantities. you have to sell a lot of units to earn back the software development.
right now I'm asking some questions about this board
FREE SHIPPING DSP, processing module, car amplifier processor, modified car amplifier processor, effects processing-in Other Electronic Components from Electronic Components & Supplies on Aliexpress.com | Alibaba Group
I can't see if the RS232 interface is part of the board or not.

interesting find ! seems to be developed by:
DA3024B|¹ãÖݾ§ÈñÐÅÏ¢¼¼ÊõÓÐÏÞ¹«Ë¾
my guess is that's a 1701 plus a micro. I see 2 crystals
could not see any control SW download at kingray, but my chinese is a bit rusty ... or non-existent

the DA3066 seems to have an ADAU1461 as the Mclk is driven at pin 2 from the 12.288 oscillator. the rsr232 is on uart level RXD/TXD, so need a USB to rs232 RXDTXD converter, a few bucks on aliexpress. also these guys circumvent the EULA agreement by having theyr own SW control the dsp instead of using the sigmastudio.
$18 DSP module + $12 programming dongle:
2, 4, or 6 Channel In and Out DSP Module for integration into amplifiers » UBUY Industrial Inc
These UBUY modules have AKM ADC on board with better SNR.

Then how about XMOS Startkit + Audio Slice:

There is no software ready software available yet, just XMOS example code and free development tools.
