Active crossover recommendations

[rgpit]

I see folks here frequently recommending using a crossover between stand mounted loudspeakers and sub woofer. I've been running my Harbeth Compact 7es-3's full range along with various sub woofers using only low pass filters. I hear the Harbeths straining at higher volumes and now I'd like to try using a high pass filter with the Harbeths. My electronics are Benchmark DAC2HGC and AHB2. I'm looking for recommendations for a high quality, low noise active crossover between the Harbeths and 2 subs.

Possible with HSU High Pass Filter.
Costs US$100.
Manual
You choose 2 crossovers, starting from 30hz to 150hz, in 10hz increments.
Uses 2nd order (12 dB/Oct) high pass filter.

Otherwise, MiniDSP of course.

Price range?

I used an inexpensive dbx223 for years. It's an analog pro unit with balanced I/O. https://www.sweetwater.com/store/detail/223XS--dbx-223xs

You could try a miniDSP if you want a flexible DSP-based solution although I am not sure it measured all that great per Amir. But it is the "go-to" sub crossover for many folk.

This is a good DIY option https://sound-au.com/project09.htm

There's plenty of options in the pro gear world. However finding anything that gets close to the level of performance of benchmark stuff is unlikely.

When in doubt, there is always Accuphase:

If you want to keep the Benchmark DAC, MiniDSP SHD Studio. I think you need a second DAC for the subs, something inexpensive like Topping E30 should do.

If you're OK selling the DAC2, MiniDSP SHD. Amir's measurements show it has a good DAC, I wouldn't expect audible differences in regards to the DA-conversion itself.

Third option would be to do the crossover in Roon, JRiver etc. and just use a multi-channel DAC such as the Okto Research DAC8 Pro.
