Any interest in a budget ($100-200) subwoofer “shootout”?

May I suggest you change to column db/ft3 to db/L? Or just to add a column with this metric.

... or, given that the majority of members here came from outside the US, switch to IS and for "domestic" purposes put between brackets their equivalent in that middle age measurements system

Anyway I appreciate your job , and what I am suggesting here would be important only if you consider weighting in room size.

Yes.


I have started porting my data from Klippel over to the google sheet. I am including the following data:

• Max SPL CEA-2010B results
• FR (normalized at 100Hz, 100dB) (because max SPL is per a given frequency, but the linearity is of concern as well)
• Group Delay

Now, I'm only 5 subwoofers in and I can already tell this is going to be messy in a year's time if I keep this up. But, luckily, one can filter the results and the plots will change dynamically. So weeding through results should be less daunting if someone has a specific size, budget, SPL, etc they want to achieve.


Here's a sneak peak.

Cool!

Are you able to add the 1 & 1.5 cycle curves?

Those subs you measured seem to have pretty good group delay, which I find odd.

I could, but I'd have to output them in to REW and then export the data. Which means additional work and I'm not sure I see the merit, to be honest.

Done.

I have spent some time this morning attempting to get the data/images embedded to my site. And while I can do it, I think I still prefer to have the excel sheet be the "go to" source. So, I have decided to simply use my site as a redirect in case someone clicks through my site.

I'm going to ask the mods to close this thread so I can start a new one with a more official post.

Thanks for the feedback, everyone.
