And moreover, the distorted sound they produce is harmful to your hearing as well, over time. All my claim is based on is the logic that, if given a choice between two compromises-lower rated-but moderately overpowered speakers, and higher rated speakers that are underpowered and clipping-I'll bet you every time that the clipping speakers will become toast first. I don't have a resource, that I know of off hand, that I can reference at this time. I thought this was supposed to be common knowledge. Assuming customary installation and use, with volume-set sound levels kept within SPL safe for hearing, there should be no problem." "For speaker and hearing, high volume settings can be dangerous driving a speaker rated 40 W with audio amplifier power capable of 100 W. So, I'm really at a loss to understand why I'd be incorrect by saying that speaker driven by audio power about 8 dB higher wouldn't be even more capable of damage to hearing (and the speaker too, driven above the maximum power it's rated to dissipate). Point I made to Sean SL relates to a speaker installed in a Miata that achieves more SPL at ears than is safe for hearing when driven by head unit power. I might guess there's confusion concerning a speaker's de-rated power capability when it's driven by audio lacking purity in its audio signal (i.e., increased signal pulse duration in audio cycles) So, please check your resources and please provide reference to maker's support of inaccuracy of the information I replied to Sean SL.Īlso, what's a reference for a speaker, and maker, that supports your claim "Good quality speakers are generally not effected by being powered by good clean power, even if it's more than what they're rated for". I'm unaware of any maker's specified 40 W speaker limit indicating capability of being driven by 100 W audio power. A good clean system, on the other hand, can be listened to for much longer, and at higher volume levels, safely, w/ no danger (or discomfort) to you, or the speakers.
The discomfort you feel after listening to distorting speakers over time, is your ears telling you that they are not happy. Conversely, speakers that are under driven, resulting in distortion, will damage the speakers AND eventually your hearing, reguardless of their quality or power rating. Good quality speakers are generally not effected by being powered by good clean power, even if it's more than what they're rated for. I'm sorry to disagree w/ you again, but the opposite is true. Its increased 1.4 dB audio power is just above the threshold of hearing-detectable, and of little consequence. That low power A/D/S 22 W is so low power that I'd not expect it to especially be a problem. A bigger sound system step increase comes from a properly operating HR speaker system.įor protection of hearing and speakers, I recommend that any HR speaker so close to ears in a Miata, be driven only by head unit power. Increased power for door speakers can help some.
Assuming customary installation and use, with volume-set sound levels kept within SPL safe for hearing, there should be no problem. FYI- its comparable operating power is greater than other Miata radios rated 25 W/channel.įor speaker and hearing, high volume settings can be dangerous driving a speaker rated 40 W with audio amplifier power capable of 100 W. It's RMS rating I think is 8 to 10? I was using it to drive 4 KEF automotive plate speakers long ago and far away.Ĥ-ohm loaded is 16 W/channel (achieved, for the Miata radio serviced).
I was thinking instead that I might bring an old A/D/S PQ8 4-channel amp out of the closet and drive the front and the HR speakers. The amp is about 70 Watts RMS, while the speakers have a power rating of something like 40 watts. I was going to install cut the leads and run my old Polk DB's as component coaxials together with an old A/D/S passive crossover and Lanzar Opti 2 channel amp. Does anyone know the RMS output of the stock radio/casette player? Hello Jeff, are you there?
