This is really a side comment and doesn't apply to main speakers vs subwoofer. I have found that frequency response down to 20 Hz is not necessarily that important, especially for music. There are definitely recordings which you can get that do go down to 20 Hz, but they are a rare item. If you really look at how most people respond to bass in music, the most important area is the 40-70 Hz area. That is where we feel and perceive most of the visceral impact of bass. The low 20 Hz rumble is nice, but if you have a hole or bass null at 50-60 hz, you will feel a significant lack of bass.
Will I benefit from a subwoofer with 20Hz speakers?
My source is a minidsp shd studio with Dirac going into Denafrips Gaia DDC to Denafrips T+ DAC to McIntosh 601 Monoblocks to Cabasse Pacific 3 speakers. The speaker's published frequency response is 41-20,000Hz. I presume this is achieved in an anechoic chamber. In my room however, it goes down to 20Hz, at least according to the Dirac measurements. In fact, I needed to flatten the curve and reduce by 5-20 DBs between 20-100Hz due to the room effect.
So, considering I already go down to 20Hz, is there anything else 1 or 2 subwoofers will do for my system? Would it create a more consistent low frequency field? I see many people adding up to 6 subs, so I wonder what I'm missing.
Thank you for your insight!

Oh, one more note. I would be very careful about using Dirac to eq the response of these speakers flat down to 20 Hz. The Cabass is stated to having response down to 41 Hz, which is definitely possible with the right 6.5" drivers. However, past a certain point, the driver response is radically reduced the closer it gets to 20 Hz. While those drivers -could- be reproducing a 20 Hz signal, the actual sound level can be something like -20db or -30db. This means that Dirac is putting a +20db eq for the 20Hz point and will create a massive over-excursion of the speaker cone if you do actually hit a sound with this frequency. This will definitely cause the woofers to either peak and clip - and can damage your speakers. |
@bishop148, did you not read the thread? If you did you would have seen my short explanation and @atmasphere's clear and informative take on the virtues of multi-subs. Perhaps you do the OP and yourself a disservice with your ill-informed dismissive reply. |
@lanx0003, a constant directivity (CD) waveguide and a horn look about the same but behave differently. Generally speaking waveguides do not exhibit any of the annoying traits that gave horns a bad name. A CD waveguide in addition to allowing a wide sweet spot also has extremely low distortion and seemingly unlimited dynamics whilst also providing a believable stage. They are not bright if correctly implemented and I find superior to any dome tweeter. In a domestic situation they are virtually indestructible. As I've mentioned before: Pink Floyd don't play through dome tweeters 😎 |
