| Bass at your ears? (Bass imaging) The bassline on that recording is a form of "wobble bass", which in and of itself does not explain the "claustrophobic" sensation. The size of the acoustic space is conveyed by the reverberation. A small space is conveyed by rapid onset and rapid ... | |
| Bass at your ears? (Bass imaging) My guess is that it’s part of the recording, and is probably deliberate. If the bass was the only instrument recorded with little or no reverb then it would be the only instrument which would tend to sound "proximate", or close to one’s ears. Sort... | |

| Stuck at home? Make a kit!! I agree with Eric that there is enormous satisfaction in DIY audio. My second pair of speakers used the drivers and crossover from a kit that KEF offered back in the late 1970’s, and performance-wise they killed my first pair of store-bought, maga... | |
| Super tweeter for FullRange Driver mijostyn wrote: "Duke, I think the L pad or resistor goes in series in front of the capacitor and driver. No?" If the input power levels are low then you can probably get away with placing the L-pad in front of the capacitor, but you LOSE the L-pa... | |
| Super tweeter for FullRange Driver Alexberger wrote: " Back of ceiling firing tweeters sound horrible!!! It completely destroys focus and sound-stage." I disagree. Quite the contrary in fact when done right, and I can go into detail if you’d like. The reason for keeping the supertw... | |
| Super tweeter for FullRange Driver Your plan makes a lot of sense to me, and imo the T90A is a good choice. My first commercial effort used a fullrange driver augmented by a rear-firing T90A. In a case like this, where you don’t have the benefit of measurements, you find the capaci... | |
| You could work for any manufacturer, past or present... Irving Fried and Earl Geddes. I worked with the latter for a little while. Might be fun to do a controlled-pattern constant-directivity speaker system with a transmission-line woofer and a first-order series crossover. Duke | |

| Speakers that can reveal orchestral instruments' positions Mozartfan wrote: "Tyler, now defunct..." Tyler Acoustics is still in business. I just exchanged e-mails with Ty Lashbrook less than five minutes ago. Tyler Acoustics is not only very much still in business, they are among the few high-end home aud... | |
| Classic Audio T1 and T3 field coil loudspeakers "Does the Hartsfield project a bigger image/soundscape due to its width?" Do you mean, because corner placement would put the Hartsfields further apart? Soundstage width is related to setup geometry. The T-3’s would not be in the corners so if the... | |
| Speaker sensitivity, impedance, and calculating amp power Thank you very much, Tvad. Hilde45, at the moment the best place to see my home audio designs is actually the James Romeyn Music and Audio website. My own website is under revision. But my feelings would not be hurt if you ended up with something ... | |
| Speaker sensitivity, impedance, and calculating amp power Hilde45 quoting the great Jim Salk: " While the RMS meter registered 5 - 8 watts, the peak-reading meters hit peaks of 200 - 250 watts during instantaneous transients (drum hits and the like). " This is very interesting information. The implicati... | |
| Importance of phase and timing optimization when incorporating sub woofers ? Mijostyn wrote: " Yes Duke but FR, Phase and Time interact." Agreed! Of course they do. And I bet that when you get the phase and time right, the frequency response is also right. Duke | |
| Importance of phase and timing optimization when incorporating sub woofers ? At low frequencies, speakers + room = a "minimum phase" system. In English, this means that the frequency response tracks the time-domain response. So if you have an in-room bass peak in the subwoofer region, you will also have modal ringing at t... |
