| Speaker suggestions for an unusual room Imo the Cornscalas are in the right ballpark for this type of room.Ime for difficult or unusual rooms, you want speakers where the radiation pattern is not too wide - say 90 degrees over most of the spectrum - and where the off-axis response track... | |
| Let's talk Tweeters! Erik, I hope you don’t mind some feedback.While I’ve participated here a bit, I felt pressured to choose my topics and my wording carefully. My impression is that the majority of what I could theoretically contribute on the subject of tweeters and... | |
| Let's talk Tweeters! Eric, I understand your desire to focus on tweeters and not speaker brands, but realistically how is prof supposed to talk about omnidirectional tweeters and not mention MBL? Frankly I cannot think of any omnidirectional or quasi-omnidirectional t... | |
| Others experience re: subs and Magmepan 20 Thank you for your kind words, imdoc! I enjoyed talking with you very much. One thing I forgot to mention - you’ll probably have to EQ in a fair amount of low-end boost in your room. I suspect that the big opening behind the listening area is acti... | |
| Others experience re: subs and Magmepan 20 Thank you very much, Tim! Glad the Debra is working well for you! The only question mark in my mind regarding imdoc’s situation is, whether his room has something going on (large area and/or open floorplan perhaps?) that results in minimal boundar... | |
| Others experience re: subs and Magmepan 20 I designed the Swarm subwoofer system mentioned above, and worked with Jim Romeyn on his conceptually-similar Distributed Bass Array system.The Swarm was originally designed with dipole speakers in mind, specifically Maggies and Quads. Briefly, di... | |
| Let's talk Tweeters! Getting back to tweeters, I don't have a lot of experience with a lot of different current-generation domes and ribbon(-ish) drivers, but I've tried a fair number of different compression drivers and many different diaphragm types. My preferences... | |
| 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, ... |
