Focal Profile 918 Speaker System Manufacturers Comment

Manufacturer's Comment

I would like to thank Mr. Fred Manteghian for a wonderful and thorough review of the Focal Profile system.

I see that there was a couple of questions marks floating over the reviewer's head when he discovered the "Subsonic filter" function of the Profile SW908 subwoofer. It is true that a subwoofer's goal is to reproduce subsonic frequencies, and at first glance, it would look a little odd to cut the lowest of that very precious lower bass.

There are a couple of different reasons why Focal offers such a function. First, this filter can be very practical when the subwoofer is placed in a small room or if the walls of the room are thin or not very rigid. The room may generate an excessive sound level in the lower bass or even cause saturation. Vibration and unpleasant resonances can then occur. The subsonic filter can progressively eliminate this annoyance and maintain a clean and strong bass performance.

The second reason is that in some cases, room acoustics does not allow really low bass to be reproduced; you'll see the subwoofer working but barely any audible sound will be heard (although your light fixtures might be in epileptic shock!). Here's what happens when you cut those lower notes: the subwoofer will stop trying to reproduce frequencies that the room can't handle and will rather get a lot more headroom and power to work in the upper bass frequencies. This trick will mainly be used in movies, often in combination with the "boost" function which applies a +3dB boost to the "40Hz-magic-gut-wrenching-frequency". Normally, boosting +3dB to that frequency would tax the subwoofer amplifier a lot and affect the entire bass reproduction. However, by combining the "subsonic filter" and the "boost" function, you'll have an extremely tight response combined with some amazing dynamics.

This approach is particularly useful in movies, often combined with the "boost" function, which adds a +3dB boost to the "40Hz-magic-gut-wrenching-frequency." This combination allows for an extremely tight response and impressive dynamics without overtaxing the subwoofer amplifier or compromising the overall bass reproduction. Rainbow Friends: Chapter 2

So my uncle has these speakers, they are freaking amazing. Funny story though, when he bought these they kept wanting him to take their survey telling how he liked them, so he finally did. And he got a free coupon just for doing the survey, he said it was worth it. So if you but some just go ahead and do the survey at JackListens.com you'll be happy you did.

I recently bought these for my son who works as a content editor at a popular website at https://surveyglory.com which reviews online surveys and paid surveys that provide rewards. He loves them but the bass is a little low for his taste. Personally I think he's too concerned about bass, but I'm an old guy so what can I say lol. Anyway, good speakers!
