Home Speaker Asylum

General speaker questions for audio and home theater.

RE: Those darn measurements !

85dB - 1 watt
88dB - 2 watt
91dB - 4 watt
94dB - 8 watt
97dB - 16 watt
100dB - 32 watt
103db - 64 watt
106db - 128 watt (speaker maxes out thus speaker is now under its own clipping called distortion/compression)

A 100 watt amp provides 3dB more level than a 50 watt amplifier at the maximum end of the volume level spectrum ONLY. SO unless one has cranked their volume knob to 10 you ain't getting zilch f-all by throwing money on a 200 watt amp. Except more negative feedback which sounds WORSE.

The KEF is designed for a small room thus 70dB at the listening chair is likely the baseline average - very few and usually only classica recordings of the pedal organ variety have dynamic swings of 30dB most recordings are in the under 20dB variety.

So even with the LS-50 you will rarely use 5 watts - I know I measure them and have meters on my now ex LM 219IA. With Tube amps that clip inaudibly compared to SS it never clipped and it rarely got into the red zone maybe once for one second in 3 years. And the amp can go beyond continuous rating by at least 50% anyway.

I always laugh at this - Audio Note wins so many of those best of audio shows even when they are supposedly clipping to the hilt - AN sounds better when it is clipping and in disaster mode than all the SS rooms when operating properly! Bwahahahahaha

I had to laugh in 2010 when I auditioned Sander Sound with his 1000 watt amp and hi res music recordings and him explaining that you need 1000 watts of power to have dynamics - listen to his system - no dynamics - not much bass and poor treble response (the thin lifeless sterile quality). 4 rooms down the hall Peter Qvortrup with his 18 watt Jinro amplifier cranks up Nightwish, Slipknott, Noisia Split the Atom and the concrete walls felt like they were moving - probably my eyeballs rattling in my head. Dave Cope had to leave the room it was so deafening with bass the would cause a bowel movement - glad I hadn't eaten anything - pin drop speed and clarity into the treble and all the way down to 20s hertz range. The poor demonstrator left the room in pain.

Had Sanders bothered to close his door for 15 minutes and walk 4-5 rooms down the hall to hear dynamic uncompressed recording on an 18 watt amp he would know what dynamics really are all about. And it's not even like the AN E is a king of this particular hill - Trenner and Freidl RA hit considerably harder with about the same power. Maybe 10 watts more. And a very good horn speaker would do better than both of these - but they're usually not domestically feasible or affordable.
