    Fantastic product!
    Very simple installation,and easy to use software to manage all of its functions.
    I was able to fix all of my multi sub installation issues (delay,xover frequency,peaks and dips) with it.
    Higly recommended for all the home teather lovers.

    It's a cheap and good solution for splitting frequencies.

    Dit is volgens mij wat Donald Jones bedoelde, dat ie het liefste in een doosje wilde doen. Kon toen niet, nu dus wel. Aanrader.

    Brilliant bit of kit. Very satisfied. I like to keep the audio chain clean. Purchased to add a wee bit of EQ between pre and power amp due to lightweight bass. ( no EQ on pre amp) This was necessary after moving speakers onto solid floor.

    works just like its supposed I bought it for the lpf and hpf and they work brilliantly +small size

    Excellent little "Gizmo" that just has the whole package. Endless possibilities of tweaking your active speaker system, which in the end gives a significant better result! I have used the miniDSP 2x4 numerous times, and every time has it impressed me with how cheap all these features can be obtained.

    De miniDSP, doet waar hij voor is!
    Ik heb het gebruikt om de pieken en dalen van mijn dual subwoofer opstelling uit te vlakken. In combinatie met de Umik-1 microfoon en REW software is dit een eitje.
    En wat een verschil! Room response nagenoeg vlak!

    En nog 2 kanalen over voor eventuele uitbreiding van mijn systeem!

    The product has great value for the money. For only €120,- you get an DSP that can be used for many applications.
    I used my MiniDSP for filtering a 2 way speaker. After i set up the 4 channel amplifier it took me only 5 minutes to let the speakers work very nicely. It will take a lot of time to improve the sound of my speakers, but with the MiniDSP being interactive it was possible to try out filter changes while the music is playing.

    I will in the near future try out the MiniDSP 2X4 HD to find out if you will hear the higher sampling rates and the higher Vrms of the 2x4HD

    The MiniDSP is a great product. Every sound-Guy should have one! You can EQ a location in just minutes! together with the REW software (open source). Fast shipping and great support! Swapping from a 2x4 to a 2x4HD was no problem and solved smoothly!
    if I may suggest: MiniDSP should be also available in an assymmetric XLR version... Even now there is not an real issue, for bands on the road it would be a bit easier to implement in the sound chain...
