Jeg faldt forleden (igen) over en såkaldt effektiv højttaler, hvor specifikationerne ligner noget fra en fantasiverden. Typisk er de store to-vejs med en 8-10" bas mellemtone og en domediskant. Et fint koncept der blev gjort kendt af Snell med model E.
Ud over at priserne på disse typer har taget en himmelflugt, har specifikationerne fulgt med. Og ingen syntes at reagere på dette?
Eksempler:
Audio Note E ($19,950 pair)
Specifications: Two-way, reflex-loaded, stand-mounted loudspeaker. Drive-units: 1" fabric-dome tweeter, 8" paper-cone woofer. Frequency response: 17Hz–22kHz, –6dB. Impedance: 8 ohms. Sensitivity: 98dB/W/m.
Stereophile reviewer: “Qvortrup suggests that the woofer's theoretical maximum sensitivity is in the neighborhood of 100dB—and the overall system sensitivity is stated as a very high 98dB.”
”In my room, with the AN-Es out of the corners, it was possible to get a generally smooth response curve, flat down to 40Hz”
Stereophile measurement: ”I have measured, at an estimated 92.5dB(B)/2.83V/m”
DeVore Fidelity Orangutan O/96 ($12,000USD pair)
Specifications: Two-way, stand-mounted loudspeaker with reflex port. Drive-units: 1" silk-dome tweeter, 10" paper-cone woofer. Frequency range: 25Hz–28kHz. Sensitivity: 96dB/W/m. Impedance: 10 ohms nominal, 8.75 ohms minimum (at 200Hz).
Stereophile reviewer: “On the other hand, the DeVores, which are notably more sensitive than the AN-Es”
Stereophile measurement: “My estimate of the DeVore's sensitivity was somewhat lower, at 91dB(B)/2.83V/m..”
WLM Divas ($5,500 US)
Specifications: These loudspeakers have an efficiency rating of 97dB and a range from 27Hz to 30kHz
Det virker som om at i dette segment (folk med rørforstærkere med få watt), er høj effektivitet og fullrange væsentlige salgsparametre. Men i virkeligheden betyder der så mindre, for reelt leveres der jo ikke på dette?
