Nice, thank you! *If* you were willing to take the extra effort, a “driver count” column for each driver size would be helpful for some future readers, even though it doesn’t relate to your initial question. (E.g. the knowledge that Level is a stereo pair, or “how could BL18 possibly sound any good with just a 4-inch woofer” would be answered by your spreadsheet too.) Again thanks.

Just for you trackbeo… Updated with Driver detail.

Also added Total Power, and Total number of Drivers to create a new column of Average Power per Driver.

£ for £ the A9 is the bargain of the current range!

Also Edge for raw power is so underrated for what it is now being sold for.

As a pure expanding my knowledge exercise, I have put the on sale range and older loudspeaker’s technical data into a table. I was seeking to understand whether there is a sweet spot in driver size &/or whether new products steal from the parts bin and repurpose with new software.

What this has become has enabled me to play a game of B&O ‘Top Trumps’.

I was surprised at the grouping around certain sizes and power, plus how certain designs use full range instead of mids.

Enjoy, and I hope this is of use to others.

Just a small comment about the nomenclature…

Once-upon-a-time I wrote a blog posting about names like “midrange”, “full-range”, and “squawker”.

If you’re interested, you can find it here. However, the whole posting can be summed up in this excerpt:

If we’re going to be really pedantic – there’s really no such thing as a tweeter, woofer, or anything else with those kinds of names. Any loudspeaker driver can produce sound at any frequency. The only difference between them is the relative ease with which the driver plays a signal at a given frequency. You can get 20 Hz to come out of a “tweeter” – it will just be naturally a LOT quieter than the signals at around 5 kHz. Similarly, a woofer can play signals at 20 kHz, but it will be a lot quieter and/or take a lot more power than signals at 50 Hz.
