miniDSP 2x4 HD Boxed USB DAC Digital Signal Processor

I needed to integrate a subwoofer with what are generally regarded as some of the fastest speakers on the planet; Fuijitus Ten Eclipse TD712Z’s on moving to a new house that was far too bright compared to my old house. No easy feat and after much deliberation I chose to try the minidsp 2 x 4 HD. A 70hz low pass filter worked well on the crossover in the subwoofer so I programmed in 48dB/octave 70hz low pass and high pass filters on the 2 x 4 HD, which was straightforward and worked perfectly first time. So the 2 x 4 HD is now functioning as an active crossover between a Naim pre and power amp, and the Naim pre and the subwoofers digital amp. How does it sound, given that it’s undertaking AtoD, applying the crossover filter then DtoA conversion? Utterly fabulous. The subwoofer integrates perfectly with the TD712’s in terms of impulse response and timing, and when DIRAC room correction is applied it really sounds stunning! An absolute bargain if you need something like this.

Helps to sort out bass and speaker settings once you follow through the instructions. It can be money well spent

Very pleased with the flexibility this has added to my setup. Running dual subs it's helped me achieve a nice integration with these which I was struggling to do manually before. I am forever tweaking the system and the dsp box gives plenty of flexibility, measuring with REW as an example and then importing filters is fairly simple, there are many guides knocking around if some pointers are required.

Great bit of kit, has made a massive difference with my 2 subs.

This has been one of the best upgrades to my system for years, forget about upgrading your speaker cables, for the price you paid for them the miniDSP 2x4 HD would make an enormous difference in comparison.
