8250A vs 8260A

Hi,

I auditioned 8250A's and 8260A's... They both sounded great, but...

1) I found the 8260A's sounded more 'relaxed' at the same SPL (80 dB at the listening postion). It seemed to me the 8250A's needed to work harder. Is this subjective or is there a technical explanation for this?

2) 80 dB with the 8250A's was just fine, 80 dB with the 8260A's seemed louder, a bit too loud actually. Subjective too?

Thanks in advance,

Serge

Hi,

1) That is perfectly correct assessment and there is a technical explanation for that. 8260A is a 3-way speaker with more powerful amplifiers and larger cabinet which all lead to higher maximum SPL, higher dynamic capability, lower distortion and therefore, more 'relaxed' sound.

2) May I ask how did you measure the SPL? There shouldn't be much difference between these models, only a little bit due to different directivity behaviour.

Hello Ilkka,

1) Good explanation! I suppose, for the same reasons, the 8260A will sound 'fuller' at very low SPL (55 dB). Is this correct? This is important for me because we are talking about a home Hifi solution and I mostly listen in the late evening when my wife is sleeping.

2) I used a simple analogue SPL meter (C weighted and 'slow'). Although the meter showed the same SPL level (80 dB as I adjusted the volume on the power amp) it seemed louder. I probably have an explanation for this difference. I was listening in a room which was not finished yet, with hard surfaces in front, back and ceiling. There was no acoustic treatment yet. Because the 8260A's were not in the same position as the 8250A's I could have suffered from more reflections than with the 8250A's. Especially in the mid range. therefore they sounded louder and more tiring. Could I be correct?

Thanks,

Serge

Hi,

1) Correct, a speaker with better bass extension will typically sound 'fuller' at low listening levels.

2) It is very difficult to compare multiple speakers placed around the listening room because the room will have different effect to speakers due to room reflections and standing waves. Especially if the room isn't acoustically treated.
