New?USD, 8260 monitors for under $6,000
Well, if you read Genelec's literature, the goal of LSE is to allow for an extremely long port. The fact that the air flow is optimal probably helps at high SPL, too.But the audible difference ports make is usually allowing air to move without chuffing, which the flared ports on the 8260 also does well. the LSE is more or less a streched out version of the ports that Genelec uses on their monitors, flared at both ends of the constricted space, but in the case of the LSE port, it's a larger surface area.
Didn't say lose. But it's obvious that vertical dispersion will suffer under and around 500 Hz, as the woofer isn't mounted coaxially. Quite visible in the measurements given: vertical is mostly smooth after 1.2 kHz.I'm curious what you mean about losing coaxial advantages. Are you talking about the dual woofers in the 83x1 range being acoustically coaxial and allowing the directivity to be controlled at lower frequencies?
Hmmm, comparing the 8351B and 8260, I see:The dispersion on the 8260 is similar to The Ones, as it's their progenitor, and measurements show the dispersion to be close. The 8361 seems to be a little closer to 45 degrees off axis before it's 3dB down, and the 8260 and 8351 are similarly close to the 30 degree mark.
* 45°: 8351: -6 dB, 8260: -3 dB
* 60°: 8351: -10 dB, 8260: -5 dB
Generally, it looks like it's more "omni".
The power response is way smoother on the 8351, though.
Wouldn't be surprised, but the max SPL of the M2 competes more with the 1237/8 than the 8260.I wish I had a plot for the JBL M2 dispersion. Wouldn't be surprised if Genelec beat them at their own game, and with 1/3 of the physical volume too.
Don't worry, I understand. The fact that a subwoofer is needer to even match the 8260 is quite a testimony by itself. While the boy inside me wants to see a 8260B, I know that it's worse than separate subs; unless you consider total volume, of course.Not bashing the Ones, as I think they are well engineered, but I think it's important to recognize where they are better (more controlled directivity in the larger models, and better vertical dispersion,) vs where they aren't quite as good, (bass extension, and dispersion in the models that are smaller than the 8260.)
Well, the specs of is the same for every model using their class D amps: 5 dB(A) at 1 m, which is very low.Also, hiss: I've heard the class D in the 8240, and they did a really good job getting rid of hiss. Anyone with "The Ones" know if they hiss even less? I should dig for the self noise measurements, as those might show it, but another concern with the newer 83x1a models is the larger, perhaps more efficient tweeter having a bit more hiss, which to me isn't worth it because the "advantage" of the larger tweeter is loudness, and I don't play any speakers at max volume or even close unless I unlock them to show off to friends.
