Would the JBL LSR 310S be a suitable match for the Genelec M030's?

Hi,

We recommend to use Genelec subwoofers with our monitors. You could try for example your new and slim 7040A subwoofer.

Thanks for your reply. Wouldn't the M030's be limited by the 7040's lower max SPL?

Yes, it will limit the maximum SPL by 3 to 4 dB. My recommendation was based on your budget. You will get matching performance by getting the new 7360A model.

Understood, thanks.

For a room of about 240x300x225cm (w/l/h), would it be smarter to simply get the M040's and skip the sub altogether?

Well, it depends what kind of LF extension you require. I am sure M040's alone would sound extremely good and provide good extension down to 40 Hz. Of course there is always a possibility to add a subwoofer later.

I don't need crazy amounts of low end, just want to ensure I can reliably hear what's going on in the bottom octave.

The combination of M030's with a 7040 is actually more costly than a set of M040's, and since the 7040 has a single 6.5" woofer, I don't really understand how it produces deeper lows than an M040 with an identically sized woofer?

Even though the diameter of the woofer is the same, it is not the same type of driver. The 7040 driver is optimized for subwoofer use and the enclosure (with reflex port) is also tuned much lower which results in better LF performance.

Bottom octave is little bit vague because for some people it might mean 16...32 Hz or 20...40 Hz or 50...100 Hz etc :)
