Decware 94+ db @ 1 watt WTF

[Ruby_Rose]

so decware came out with a set of monitors THAT RUN 94+ db @ 1 WATT.

 

OPINIONS PLZ

[The Official Czex]

>inb4 95dB @ 1kW

[EndlessOyster]

There a bit expensive for what they are.

[KaminKevCrew]

They're hardly the least sensitive speakers ever made.

[SSL]

Um.

 

94dB/W seems pretty sensitive, actually.

[t0wer]

not the most efficient, but it's on the higher end.

I thought I remember hearing about a 99db speaker using a tang band driver, but I'm not seeing it now.

From that page, I want to get a sound system like this for my bike:

If it could handle 1kW (which it can't) you'd get an output of 134dB. Pretty impressive, sadly speakers suffer from all kinds of thermal and mechanical limits

A lot of those sensitivity ratings aren't strictly true; they pick peak sensitivity and give bass extension to -10dB instead of the industry standard -3dB.

The numbers often get manipulated to seem as big as possible without really lying.

 

You can't get more output than input, because nothing in this world is 100% efficient.

So with 1W electrical in, you can't get more than 1W acoustic out, which is 114dB in half space IIRC.

And all moving coil drivers (>99% of the drivers on the market) behave as described in Hoffman's Iron Law:

It describes the relationship between bass extension, airspace and efficiency. If you want bookshelf speakers that are efficient you will have to sacrifice some bass.

 

The most efficient speakers I've seen are made by Danley Sound Labs, approaching 40% efficiency. Can't remember which model, but it wasn't small for sure

I hope you're kidding ;p

i have them working on custom monitors for my studio that will be 2000 watts per driver and would be close to the same wattage to db ratio

Euh can you share some details. This breaks a lot of phsyics laws, I think there's something wrong here

i asked them to build some monitors that would be 2000 watts peak running as close to 96 db @ 1 watt as possible i dont know how close they will get it but they said they will try.

[Lutkeveld]

Oh gosh, I feel kind of sorry for you. You don't know what you're saying and they don't know what they're doing. Or even worse: they know what they're doing and are trying to scam you. 

 

It feels like a newbie going to a car dealership saying 'I want a car with 1000hp and 0-100km/h in as quick as possible'. The first is not possible, the second is too vague. They end up selling you something that's too expensive for what it is anyway.

 

Do you have some more details for me, I'm interested in the whole story.

[Lauen]

Yeah, and? my Phonar Micro 2 does 91 dB at 1 watt. 

[Lutkeveld]

94dB is more than double that.....

 

But in the end it's all a compromise. You can't get around hoffman's law.

If you want high efficiency in a small enclosure you sacrifice bass.

i do know what i am doing i've ran live sound for several different venues including edc, installed av equipment through audio midwest, and have a home studio, i asked them to have the CLOSEST possible specs to the monitors i posted about but in a larger top cab (horn, mid) for live events while being able to run as close to 1500 watts rms and 2000 watts peak as possible i would be running seperate subs, i would be running this in my live room at my home studio.

@Ruby_Rose 94db sensitivity == 1.5% efficiency. Which means 1970 Watt has to be dissipated in the voice coil of a 4 to 6 inch woofer. A 1970W radiator could easily heat a complete room, you don't want such heat coming out of your speakers. That's not even your primary concern, because your speaker will be way past its mechanical limit with those numbers. Are you also under the impression that more watts is better? Because more watts only means it'll be louder, since you'll only be providing (not for a complete audience) I don't see why you'd want 2000W here.

 

It may very well be that you're very good at the practical stuff, I don't know you personally. But it sounds like you could use some help on the technical part, which a forum is perfectly suited for Which company is building them for you? Why do you think something like a JBL LSR305 doesn't suit your needs?
