Subwoofer Comparison

Very cool,

What are the room dimensions these beasts are located in?

Odd shapped room width varies from 11 to 14 ft. Length is 23 ft ceiling varies from 8 to 9 ft. I have speakers in one end with LP 6.5 ft away so mid field which seems to help a lot. I

Looks like Brent Butterworth updated his spreadsheet in February:

Edifier T5s is at least one new addition. Performance (scaled to 2m) seems quite nice for the footprint & cost (only 110€ on amazon.de). Would make for a cheap compact MSO desk setup for example

Does T5s have a high pass filter for RCA outputs?
Manual says: "This adjustment determines the crossover point inputting to the subwoofer. Bass signal below the crossover point will be “handed over” to the subwoofer for playing."
It doesn't clarify if RCA outputs full frequency signal or only the frequencies above the crossover point...

There is no high-pass filtering for the satellites in the subwoofer; the looped-through signal remains unchanged, deliberately leaving the responsibility for separation to the user or the connected speakers.

The table on that page says the info is from the manual, but the later teardown page shows the ADC and integrated DSP/amp so there's nothing to apply a matching high pass to the RCA outs. Perhaps it's a bit much to expect at this price point?

I would assume the omission is due to their cheap newer app controlled DSP speakers (MR3, MR5) already having adjustable high pass filters

Ok, there is a lot of data here which I appreciate, but where are the recommendations or scoring? E.g. Spinorama is ranked by tone score. All the columns under hz mean output level at various tones? How much dropoff and variation is acceptable? Sorry if I have to ask, but there is a lot of good data on ASR presented without any conclusions.

Not sure what you're expecting? Someone collecting this data on their spare time is also expected to interpret it for you? If you want some assistance in making a purchasing decision there are plenty of forum-goers willing to help with that. You'll need to provide some basic information about your circumstances, though: room, budget, aesthetic/space considerations, how many subs you're looking at, the rest of your system, any DSP/room correction you have available, etc.
