Hi there,
My 21 month old daughter turned my amp up ALL-THE-WAY, and partially blew my 170s. So, I've decided to replace them with Sierras (yeah, baby!). The amp is a Marantz PM7001, 70 watts/channel into 8 ohms.
Now, I'm worried that she might crank the amp with the Sierras, and blow them too. I can handle accidents with $300 speakers.......but not $900 speakers.
From what I've found I have, basically, two approaches I can take.
1. running fuses in-line to the speakers
2. installing a relay circuit that blocks DC from the speaker
Regarding 1: Does anyone know if installing fuses will provide adequate protection? Will they blow quickly in time to save the speakers from overload?
Regarding 2: Is a DC blocking, passive circuit really going to help in case of overload?
Do either of these approaches degrade sound quality?
Any other recommendations?
Thanks folks,
Jim
Does any
