| Let's talk Tweeters! Thank you for that information and for digging up those examples, Erik! Interesting that the less expensive speaker beats the more expensive one not only in deviation from linearity, but also in radiation pattern smoothness - look at the 45-60-75 ... | |
| Let's talk Tweeters! My understanding is that there are two general areas of thermal compression effects. The one that has been studied and documented the best is what we might call long-term compression, which arises from both voice coil heating and magnet heating, t... | |

| What are the smallest speakers that are clean and flat down to 20hz? One implication of the Fletcher-Munson curves is that the ear is quite sensitive to changes in SPL at low frequencies (recall that the curves bunch up in the bass region). Thus a 5 dB change at 40 Hz or so is subjectively comparable to a 10 dB cha... | |
| Vandersteeen 2wq (or any sub) in small room Smooth bass = "fast" bass, because frequency response peaks in the bass region literally decay more slowly. It doesn't matter whether these peaks originated with the subwoofer or with the room - the effect is the same. But the room is almost alw... | |
| Corner loading/left louder ? The early reflections off the nearby walls on the corner-loaded speaker have the effect of increasing the loudness of that speaker.Not much you can do about it in the bass region, but it is possible that aggressive use of absorption on those wall ... | |
| Speakers with external parts, gimmicks or serious? Most of my home audio speakers include an external "resistor in a cup" that is wired in parallel with a resistor on the crossover board (which is inside the speaker). This external resistor functions as a "tilt" control for the tweeter; that is, ... | |
| Dynamics In A Speaker Ime preserving dynamics has to do with minimizing those things that cause compression, namely voice coil heating, subsequent magnet heating, flux modulation, and mechanical system non-linearities. Voice coil heating causes rapid-onset thermal modu... | |
| When speakers duplicate drivers Using two woofer to cover the same frequency range is neither inherently good nor bad, it just depends on what the designer is trying to do.Compared to using a single woofer, using two of that woofer to cover the same frequency range lowers the di... | |
| What are the best subwoofers to use with Magnepan 20.1s? James Kates published a paper in the Journal of the Audio Engineering Society years ago that showed dipoles to have smoother in-room bass than monopoles. Since getting smooth in-room bass at low frequencies is difficult at best, getting in-room ... | |
| Speakers VERY close to wall - Cork board useful? Willy Wonka’s cowl increased the effective port length and lowered the tuning frequency, which is the direction you want to go to compensate for the increased boundary reinforcement from placement near the wall. I incorporate variable port tuning... | |
| Speakers VERY close to wall - Cork board useful? Four inches should be plenty of clearance for the ports. Even a bit less is still functionally fine - as the port gets closer to the wall the effective tuning frequency moves lower, which is the direction you'd want it to go. I assume that the co... | |
| Help pricing a set of horns DIY speakers don't have much resale value unless the buyer has heard them and likes them.You might be better off selling the individual component parts piecemeal. | |
| Concert Experience for $5k? The bass impact and naturalness you are seeking call for a speaker system that does a good job of taking the room’s effects into account, otherwise the room will impose unacceptably large peaks and dips on the bass region. This is a problem inhere... |
