prv dsp

[jamescarter1982]

hi i noticed this cheap little dsp and watching a YouTube video it seemed to offer quick adjustments of crossover frequency and level . I wondered if something like this would be worth the small outlay for developing a crossover for active speakers which could then be made permanent using something higher quality ? does anyone use something like this for speaker design ?https://amzn.eu/d/hjCj52u

Tried one for a cheap car audio setup before.

Crossover + time alignment functionality is good.

PEQ is limited, single band on input and each output. Remainder of EQ is fixed band.

Programming is annoying. No digital input, knob + button only.

thankyou . my idea was to use this device to decide on crossover frequencies then use an analogue fixed frequency crossover like one from xkitz for the final speaker . the only thing I can't see is how I could put any delay in an analogue electronic crossover

Delay is essential for car audio. You should include it in the system one way or another.

thankyou . I was actually thinking about using this as a quick way to try out crossover frequencies for home diy speakers then putting a better quality fixed crossover in place . I just wondered if anybody else uses a dsp like this for that purpose

You can do crossover development with a just a computer. If you have a 2-way you can use any stereo jack together with DSP software such as EqualizerAPO, CamillaDSP, Voicemeter, etc. Sound cards with 6 and 8 channels are readily available too.

thabkyou . do you do any speaker development in this way ?

There are also "pro" active crossovers. They aren't designed to be built-into multi-way speakers (or car stereos).

If you need delay it should be digital. There were analog delays in the analog days (usually analog tape) but digital is far more practical.

Yeah, I do a little tinkering. I usually don't make analog crossovers, instead running PC-based active systems. I don't really want to make 3-way 4th order passive crossovers. I think digital is the way to go for stereo systems, but if you want surround sound you start running out of channels.
