Hello,
I was looking to build a speaker but to my surprise the Crossover parts have become really expensive (one Crossover would cost 75€).
Now I am seriously considering using a 2 way amplifiermodul with a DSP instead.
The speakers have a Seas DXT tweeter (55W RMS) and a wavecore 182 woofer (85W RMS).
While looking for amplifier modules I found that they all seems to have equally powerful channels. Is that a problem? Because I assume the tweeter channel will run at much lower power than the woofer channel.
would you recommend using a two way module for each speaker and integrate it or rather use an external amp?
Thanks 😊

Is that a Seas DXT H1499-06 27TBCD/GB-DXT ?
Yes - Amplifier module per speaker, this is a modern way of doing things, not the most cost effective but worth it, parameters are adjustable on the fly, lower distortion ect. it's all obvious gains. One point to mention is make sure the amplifiers are identical, you can tame the tweeter with gain control from the DSP.
I would advise you choose something better than a AD1701 the industry is flooded these 28/56-Bit Audio Processors and their average DAC outputs
suited more for subwoofers and mid tier soundbars.

Yes it is that one
Do you happen to have a specific "low-budget" but still some what decent recommendation?
The ICEpower 125ASX2 2 x 125 W seems to be a popular module, but way too expensive for my taste and probably too overpowered too (some headroom can't hurt, but 125W is probably a bit too much)
# DSP/DAC Solution.

Interim: Use the AD1938_CODEC comes with the kit. (Future Recommend: Roll out your own DAC pcb)
# Amplifier(s) + PSU.
Chat to member @Sous and use he's Class-D Ncore Amplifiers + PSU not sure of price x4 strike a bargain?, It's hard to recommend crap amplifier(s) given the driver solution.

The output signal level is limited by the DSP, i.e. it all depends on how you configure the DSP output that controls the amplifier output. In other words, there are no problems if you control the speaker through an amplifier connected to a properly configured DSP.
If you don't care about the analog input, then pay attention to this solution. Although it is designed for three channels, if any channel is not used, it automatically goes into hibernation and will not consume excess energy.

If you are afraid that the amp will blow up the tweeter, it's not going to be a problem. An amplifier will not "push" all its power into a driver forcibly.
As mentioned above, how much power gets to go through the tweeter, depends on your gain and how it's set in the dsp. If your tweeter is high impedance model, it will not draw full current from the amp. I would recommend using higher impedance tweeter than that of the woofer, because it also helps with matching levels.
Thank you all 🙂
@Reactance What do you mean by "Future Recommend: Roll out your own DAC pc"?
@uriy-ch: That looks interesting, I've written a message in your thread. Theoretically it would not be a big deal to Use a ADC (inversion of DAC 😀) to gain analog inputs, would it?
