| High Sensitivity Speakers that work best with SS If we take the words "high sensitivity" to mean "high voltage sensitivity", then here is my suggestion: Look for "high sensitivity" combined with a low rated impedance, like 4 ohms or less, and preferably with a nasty-looking impedance curve (a de... | |
| Speaker choice: impedance, sensitivity, and tubes Bifwynne poses some excellent questions. Bifwynne: When a speaker manufacturer publishes frequency response specs, how can they possibly apply to BOTH tube and SS amps at the same time?Duke: If the impedance curve is fairly smooth, then there will... | |
| Sealed, Ported, or Passive Radiators? I'd be more interested in using multiple distributed subs covering the whole bass spectrum than in using different subs for different portions of the spectrum. The reason is, if you spread multiple low frequency sources around the room, each one w... | |

If designers such as John DeVore and Alan Yun (Silverline Audio) understand this quite well, why don't others?"Because most... | |
| 12' x 14' room; $10k budget for speakers; help Maxh, it sounds like you are quite familiar with live music, and there are two areas in particular where most speaker systems fall short. Neither is obvious from published specs.Dynamic contrast is one area where most speaker systems fall well sho... | |
| Which loudspeakers work best close to back wall? If a rear-ported speaker is tuned specifically for placement close to the walls(s), it works just fine in such a location. That's one of AudioNote's secret weapons - a low-tuned rear-ported box whose basss response relies on generous boundary rein... | |
| Audiophile Speakers with 25 yr + Longevity Quite a few older speakers with prosound-style drivers still work and work well. Vintage Klipschorns, Altec VOT, Valencia, Model 14, Model 19, JBL Paragon, Hartsfield, Model 4430, to name just a few. These range from 30 to 60 years old ballpark. D... | |
| Sealed vs. Ported Speakers Several years ago I experimented with sealed and ported versions of a monitor speaker designed to be used with a sub. In other words, I was focusing on the midrange performance only; the low end didn't matter. I arranged a simple blind listening t... | |
| The most dynamic speaker you've heard... "Has anyone heard Casta Acoustics? Would the model "A" specs fall into the realm of great dynamics compared to my Paradigm Signature S2's(V3)?"The 93 dB efficiency of the Casta Model A bodes well for good dynamics, though I'm a bit nervous about w... | |
| How to get the impact of a live concert? Thanks, Mapman.The actual situation with regard to dynamic compression is more complex than what I described above, but I don't fully understand all the mechanisms at play. The I've seen measurements which indicate that the advantages of high-effi... | |
| The most dynamic speaker you've heard... Mapman, I haven't heard a field-coil version of the CAR Hartsfield, but it would probably surpass the "regular" version that I've heard several times over the years. Dukedealer/manufacturer | |
| How to get the impact of a live concert? One thing to look at is minimizing thermal compression.As a ballpark rule of thumb, a driver will exhibit about 1 dB of thermal compression at 10% of its rated power. Now this "rated power" would be according to some engineering standard. Usually ... | |
| Building new house need advice on a dedicated room I agree with Soix's recommendation of the Geddes book. Don't let the title put you off - the chapters dealing with acoustics and room construction are totally applicable to two-channel. If you'd like to engage a top-tier professional who is still ... | |
| The most dynamic speaker you've heard... Most dynamic home audio speakers I've heard were the Classic Audio Reproductions Hartsfields. Duke | |
| What component is responsible for dynamics ? "Duke and John;You two build with two different driver designs , is there an opinion on the type of drivers that work best for dynamics ? I don't want to start a battle here, just personal opinions."Ha! If JohnK and I get into a battle, it'll prob... |
