JA Perspecitve Stereophile review
Atkinson's said his measurement indicated that "the Perspective's tweeter is balanced a little hotter than the Pulsar's, though its response is even overall."

Yep, the tweeter level and even the shape of it's output is controlled by the crossover, and ultimately the speaker designer. I could easily adjust that on any of the 3 different models I listen to at home. The overall balance also matters a great deal. It's not just what the tweeter is doing but what the bass is doing, as well as the crossover point and therefore radiation pattern, so it is important to hear speakers for yourself, in an environment similar to your own. This may have been JA's failing in the case of the Diamond's. He set them up with poor bass, and he attributed it to excess mid/treble energy. Best, E |
I should also point out, treble balance can be affected by room acoustics. including what’s on the floor between and behind the speakers. Most audiophiles are into first reflections, but try throwing some blankets around. :) Between the drivers, crossover and room is where most of this balance is achieved. Best, E |
Most audiophiles are into first reflections, but try throwing some blankets around. :) On that subject... I enjoy playing with acoustics, generally speaking. Always have. I remember in my late teens taking some really cheap small speakers and loading them into room corners, augmenting this by actually putting them in a type of box/shelf. It turned the tiny speakers in to monsters that cast a huge sound with the impression of big bass. It never failed to blow away my pals. When I go on vacation and all I have is my iPhone for music, I’ll play around with putting it on different surfaces. Throw it on a bed and the sound becomes smooth and mellow, less tiny and electronic. Or I may place it into the well of a desk, turning it into an acoustic amplifier for a bigger louder sound. In my current listening room, which was designed with the help of an acoustician, I can play to some degree with the liveness or deadness of the room, by shifting around some thick curtains - e.g. over first refection points, or off, or over other points (my curtain track allows the curtains to slide or be bunched anywhere along the full side walls and back walls). I recently purchased one of these: https://www.acousticgeometry.com/products/curve-diffusor/ And first placed it at the first reflection point near my left speaker (which is close to the fireplace, over which I usually pull a thick curtain that kills the reflection hash). I didn’t care for it at the first reflection point - made things a bit harder sounding than I liked (though it was technically speaking closer to the speaker than you normally want a diffusor). However, playing with it around the room was really interesting! I found one spot actually just to the rear of the left speaker which seems to both lock in the focus of the images, especially centered images, and give a bit more solidity and liveness to the sound without giving up the organic timbre I’m used to. So now it’s become a permanent part of the system. |
