There are 3 methods of implementing a 'High Pass Filter' (aka HPF). (See below for explanation).ДЄlso known as 'low-cut filter'. But some listed 'USA-only' warranties, so I used those links where possible. Most mfg websites just listed the one warranty (usually for all countries). For some, I added alternate name or product #s for subs. I classified subwoofers with extra classifications, like 'sphere' or 'cylinder' or 'PA sub' or 'low profile (<8in) (aka pancake subs)'. See tab 'Bassaholic' to understand how I calculated this. My Calculated Audioholics' Bassaholic Rank

For Canadian and US market, I know the market well, so it was easy to find reliable price data. I specifically ignored website that sell 2nd-hand, like ebay, etc. If 'n/a' it means I couldnt find any reliable sellers that sell that item. If non-bold, price was taken from 3rd party website. If bold, price was taken from mfg website. Link to pdf, to save you time having to hunt down the links I look at the mfg website to see if there's any indication this was discontinued Inside the spreadsheet, can you explain the 'Table Legend'? Note: Erin also tests CEA-2010-B standard, but since he's the only one, there's no point including this data.yet. Since Erin's format (2m Peak SPL) matches my table, nothing needs to be done with this data. I have to add 3dB to ' data' in order for it to be equal to what i'm showing (which is 2m Peak SPL).

I have to add 3dB to 'Audioholics data' in order for it to be equal to what i'm showing (which is 2m Peak SPL). NOTE: this will change over time, as AH uploads a new spreadsheet I have to subtract 6dB from 'Brent's data' in order for it to be equal to what i'm showing (which is 2m Peak SPL). Here's the latest CEA-2010-A data from Brent Butterworth:
