So... Which is which..???
Ok, time's up (and jayjo wants to know the answer). The blue graph is the S8R plot. It shows a better midrange response (200Hz to 1kHz), but the A8X is far smoother from thereon up, due to its Ribbon tweeter. Also noticeable is high frequency drop-off starting below 15kHz for the S8R. The uneveness in the low ƒ response is due to the room modes.
Thats what I expected... thanks alot!
Hi Richard, i have a pair of a8x... but i feel a hole on the 100 hz.... below at 90 hz is ok... and above...150 too(sometimes loud)... i don´t know.. what is...
how can i solve this???
At frequencies below the Schroeder frequency room modes come into play. The room dimensions cause standing waves that will give cancellations and reinforcement at bass frequencies . This will be why you have a dip at 100Hz, and a peak at 150Hz. Solutions are: use a room with acoustically designed dimensions, choose a different room (you might get lucky), move the position of the speakers (again you may get lucky), or install bass traps (usually in the corners) to attenuate the boomy frequencies.
There is another approach too: a crude way to fix the problem is to use a 1/3 octave graphic equaliser.
Tks Richard... i´ve already email adam audio and seems they have the same opinion.... problems with room acoustics....
Hi... Have you some problema with a8x mid range freq in the mix??
Manu reviews talk about this...
