I measured 10 subwoofers.

[Nuyes]

Is the data measured using CTA-2010-A or CTA-2010-B standard?
If it's CTA-2010-A, then i can add it onto my main spreadsheet, since all of my data comes from -A standard measurements.
If it's CTA-2010-B, then i need to create a 2nd spreadsheet, and add your data there, since -A standard is different from -B standard.

I used 2010-B.
Thank you for your hard work.

What an Herculean task! Great work !

Now on to the Augean stables !!!

@amirm
Surely this belongs on the home page. Great work which will take some time to digest.

Makes it obvious how badly behaved rooms are below 200 hz.

That's a lot of work, and you got some nice subs there! The Arenal's and KH750 look pretty good, and the DIY. I wish you could have done the 1723 too!

The picture in the 1st post takes me back to the days @Ilkka Rissanen made same kind of open field sub tests in Finland, must have been about... 20 years ago.

He made a lot of measurements of the TC Sounds LMS Ultra subwoofer, which I have attached for comparison

Wow, that`s such a mountain of work, one gets tired from just looking at it

CEA-2010 is a surprisingly hard standard to measure consistently, but it seems you have done a pretty good job. Checking the two Arendal subs against the tests done by Audioholics (who has got quite a lot of experience with this), it seems reasonably consistent. But it's 1-2dB off here and there, which is normal to see when comparing subwoofer reviews and CEA-2010 measurements of the same sub from different reviewers.

So looking at CEA2010 measurements from various reviewers one can't expect more than +/-2dB actual precision in the data.

Great job on doing so many detailed measurements!

Incredible effort. Thank you!

Amir just put it on the top of the Review page.

Yes, it was said earlier, based on comments from
Buchardt maker about recommending its clients
NOT to buy A700 if to be placed in a small room "..as they will get not benefit of having a speaker like the A700 that goes straight down to 17 Hz...." (Said @46:30)

Why do subwoofers have better bass than large speakers?

dts demo cd disc goes well below 20Hz for music effects and digital dts surround , goes extremely dynamic below 20Hz use with caution ! titanic dts cd music is also wow

Nice work!

 

[Ron Texas]

Good job!

 

[098765]

Phenomenal work! It indeed helps me to compare those subs.

 

[Huang Jerry]

Tremendous effort with the copious amount of detailed measurements!
Very unhelpful in quenching my desire to buy a KH750 though

 

[Svensson]

The data is just brilliant thank you. Combined with data presented by @sweetchaos I can consider and decide my personal best financial compromise. This is exactly what most members here need.

 

[DJBonoBobo]

Thank you very much!
I feel i don't know enough about comparing the graphs, though. Could someone help dumbing it down a little? Is it possible to make a general "ranking" of the subs, or are there "disciplines" in which some models are better or worse than others?
I thought, for subs more or less only one measure was important: how much output they can provide until distortion becomes too high. (in relation to size and prize). But here is so much different data i don't know what to do with really.

This is the table you're looking for:


It shows at different frequencies the maximum SPL before distortion becomes too high, acc. to CTA-2010-B.
The standard is explained here and can be downloaded here.

Edit: Nuyes also plotted that data in a graph:

I also struggled / still struggle a bit with this. My low capacity brain works on the following.

1. What frequency range do I need covered? In my case its 65hz and lower
2. What dB levels do I need to match my speakers and listening levels? Can the sub produce that range of hz at a matching dB level but not maxed out into or too close to distortion
3. Is distortion going to be an issue
4. How much money

 

[Joachim Herbert]

Amazing work. Glad I had no choice than to buy the KH750 to go with the KH120.

The diy sub looks great, though.
