Audio Loudspeaker basics and what to look for

[balashome]

Everybody,

I found this guide invaluable. Thought I would share this with everybody here. Though I am sure most of the heavyweights here already know this beforehand, maybe it will be useful for somebody like me searching for the ideal speaker.

PSB Speakers - Guide to Speaker Specifications

Mostly a nice article but I disagree when they say that running a 4 or 6 ohm speaker can destroy some amplifiers in the long run. All solid state amps will run a 4 or 6 ohm speaker day in day out. How it sounds is a different issue. Tube might have issues.

so an audioengine a5 with sensitivity of 95db/w can churn out a loudness of ~110-112db (95+10log P2/P1,p2=50w,p1=1w) at continuous 45-50w per channel! That's loud! Pretty good guide...

^^Err where does it say that the drivers in the AE5 are 95dB sensitive?

 

[rPOk]

sorry my bad..I took their SNR no. here...Sensitivity is 88db...so there goes my wrongly assumed extra 7 db ...

Thats still very good sensitivity, rPOk - from whatever I have read. As I said I am looking forward to your feeback on the Audioengines.

According to this site here: Logitech | Z-5500 - 5.1 505 watts Computer Speaker | 970115-0403

The Z-5500s have 93.5db sensitivity on the satellites and 100db on the woofer. So that's not bad, although they have 8ohm impedance.

yeah but we shouldn't forget that this is only a measure of loudness (and actual power delivered)...it doesnt say anything abt sound quality...

I whole heartedly agree with that.hyeah:

Any one in Bangalore have the Audioengine 5. I would love to hear them some time.
