Application notes on miniDSP 2x4 Kit

In this application note, we will show you how to design an active 2-way loudspeaker. 3-way and 4-way speakers are an extension of the approach described here.

In this application note, we show you how to use miniDSP to properly integrate a subwoofer into your system.

In this application note, we show you how to use Room EQ Wizard (REW) and its integration with miniDSP to equalize your subwoofer.

I build high quality mobile loudspeakers.
So i use the mini DSP as an active crossover.
It work verry well.
I think its an amazing product.
The wide voltage range is perfect!
Now i have 5pieces in use and no issues!
Good job, go ahead this way.
Allways 5 stars!

Shipping was about a week to the USA. Installed in a car audio system. Don't worry about clipping due to only 2volts. I have an Eclipse head unit with 8volt out and don't have any clipping issues. Also don't worry about low output voltage, it drives my amp loud and clear with my gains between 1/4 and 1/2. It is a 75wattsx4 channel amp. I am running the 2way advanced plugin. I think it sounds spectacular after it is setup! and by the way I am running a two way front stage with no rear fill. I would by this again and again!

I received it at 1:00 PM and by 4:00 PM I had built a crossover and equalized a dipole speaker. I could have used this thing many times in the past, and will many times in the future.
