The pair of speakers causes a 3dB increase, the room typically adds 6dB, but the change in distance from 1 meter to 4 meters results in a 12dB drop. But, for the sake of determining how these speakers perform at the higher end of music listening, let’s assume the following: 1) you are in your room and about 4 meters (~ 13 feet) from the speakers and 2) you listen to these speakers at about 90dB at the listening position. I’ve often found people tend to overestimate their listening levels by a fair bit. Few people realize just how loud 90dB is. However, based on a poll I conducted, most people’s in-room listening distance is between 3 to 4 meters from their speakers at a volume of about 85dB to 90dB. Those numbers are pretty good on their own. Namely, near the speaker’s roll off point. As you’d expect, the distortion increases as volume increases. Distortion at this output is under 0.50% above 200Hz and hits the 3% mark at about 40Hz. At 2.83vRMS the mean SPL is about 85dB at 1 meter (over 300-3kHz). What you see below is first the Total Harmonic Distortion at varying output levels. With that in mind, what you see below is first the Total Harmonic Distortion at varying output levels. When a crossover is used the compression near the speaker’s Fs is attenuated and overall the compression effects are mitigated. Generally speaking, higher sensitivity speakers (like pro-audio speakers with 100dBSPL 2.83v/1m spec) suffer relatively no compression while lower sensitivity speakers (low 80’s dBSPL 2.83v/1m) suffer more compression. The reason I chose this speaker for review is simple: I was hoping to find nice performance on a relatively small sized tower speaker that is typically 2dB). Companies should easily be able to provide better response “out of the box” than this and you can then tailor to your needs. People are paying for something they are not getting. Aside from having terrible linearity, the box claims a +/-3dB response window that just is not accurate. ![]() People seem to miss the point that while these are indeed “cheap” speakers, you should expect more. Update: Over the past month since this review was posted I’ve gotten a lot of people saying “what did you expect for $280”. First off, I’ll just save you a lot of trouble if you’re a casual reader or someone wanting to know if they should buy these speakers for budget friendly hi-fi stereo use: Do not buy these speakers.
