Hi!
I consider buying a subwoofer, but I'm not sure if it will do what I hope it will.
Let me try to explain what I'm looking for. Many years ago, I helped my parents buy speakers. Final choice was between their then current old square boxes from the early 70's (Radio Corp), and 2 others. The Radio Corp had about 11 inch woofer, and 2 maybe 3 inch tweeter. They lacked high frequency, were boomy, bad stereo image, but were pleasant to hear with an unconstrained feeling to the sound. A contender had great everything, punchy, but felt constrained, and was rejected. They finally bought B&W DM3000 speakers that had everything for themselves, apart from the price...
Fast forward today, I own B&W 683S2s. I'm quite happy with those, but when I visited my parents, I helped them with fixing a problem with their TV. I had my head close to the speaker and it struck me. Their speakers seem to sing effortlessly, (or breath easily or unconstrained), while mine don't!
Since I now have the old Radio Corp, and since the DM3000 are quite bigger than my 683, I tought: easy, that must be because they have better bass response! Let's add a sub to fix this!
I'm not sure after taking a look at the specs: -6dB at 30Hz for the 683 and -6dB at 35Hz optimized to give flat 3rd-octave response down to 20 Hz for the DM3000.
I know for sure the FR of the DM3000 is better. I had the measurement and it was roughly +/1 dB, while the 683 seems to have weird bumps in it, maybe a bit worst than +/- 3dB. THD are the same.
What does the optimized... means?
What can cause that constrained feeling, what measurement is linked to this?
Can a sub help with this?
Thanks!
