managing subwoofer and main speaker cut-off? how you would like it done???

[TonyJZX]

i dont know where to put this except here

i generally am not a huge fan off 2.1 systems but realise that this is likely going to be popular but its clear that its not managed correctly by companies, nor is it well documented, nor is it well understood by the consumer

now let me refer to you a device that does this quite well IMO... not the best but better than most

the Arylic B50/BP50 is a well known pile of shit as seen here

Arylic BP50 Preamp with HDMI ARC Review

This is a review and detailed measurements of Arylic BP50 preamp with internal DAC, phono stage, HDMI ARC and Bluetooth. It was kindly drop shipped to me by a member and costs US $99. Front panel doesn't hint at the immense amount of functionality BP50 provides. You get that from the back...

when it was reviewed it had an excreble system where you could set the sub in 50hz increments

so 50-100-150-200 up to 300 i think

everyone hated this - but it did work as documented

so if you set it to 100 it sent <100hz to your sub and and > 100hz to your mains

people complained to arylic and to their credit they went overboard and now it does something like 50 - 300hz... in 1hz increments... which is way too much granularity... but they delivered I guess

it seems that manufactuers are just slapping in a sub 50hz filter on their amps and they reckon that's good enough?? is it though? I dont think it is

and that's before you get onto box placement and room acoutics but thats a problem for the likes of minidsp

Variable crossover frequency selection is an important feature, the filter slope is even more important (>24dB/oct is good), make the slope selectable is even better.

Subwoofer management is MUCH, MUCH more than a simple crossover. And the best place to implement subwoofer management is not on the sub itself. It is ideally implemented upstream of the sub. If you do it this way, then the sub does not need a crossover, phase controls, and the like. All it needs is a volume control.

For me, a proper AV processor was the obvious choice (Anthem AVM70).

THe DSPeaker X2 is an affordable DAC with subwoofer management and dsp room equalization.

I could do it better by putting out dual stereo to both sub and speakers. But I can tune well enough using the LPF on the sub. The sub can hpf at 80hz out to the speakers but I don’t like it for some reason (on both speakers I’ve tried).

I was going to start a similar thread as moving from 2.1 to almost 2 full range speakers gives me some room issues. 80hz is so consistently low on 1 speaker that I felt compelled to check the SPL on both speakers (using my phone).

Unlike previous reflections/nulls I’ve heard, it seems to be relating more to where the speaker is than I am. I can almost have my head at the speaker and it doesn’t get louder.

I have had good results using miniDSP products to manage the subwoofer/speaker integration, first with a SHD, then with a HTx when I went all active.

If music was my only use case, I might have swapped my AV processor for a HTx. But I do watch movies, so handling video and various audio codecs is needed.
