LOL

Well, except for the day that nobody else is home and you decide to crank WOTW to bask in the LFE glory. Then that other 999 watts becomes useful, at least for a fleeting moment...

From what I understand of amp ratings and design, a 1000w amp is not designed to output the whole 1000w continuously for hours on end. That is not what music content demands and that is not what engineers design to.

When was the last time you guys mentioned the VP160?

Chris, I've emailed that post to myself so I can read it carefully when I have more time.

In the meantime, though, THANKS!

You're welcome. Please ask for clarifications where needed.

Club Neon,

Great analogy; I've used it myself at times. I think you got the voltage/current thing reversed, however.

Voltage provides the "push" or pressure behind the flow of water; current, in amperes, is like the diameter of the pipe. A big pipe, like a firehose, enables a big flow of current. A narrow pipe restricts the flow of the water.

Big fat wires like jumper cables carry tons of current "pushed" by a low voltage (12 volts in a car).

Cheers,
Alan

Hi Jay, Micah and all,

quote:

"If in fact a ported design holds an advantage in the area of bass extension, then I'm curious why they would take what seems like 'the harder road' to getting the EP800 to hit those awesome low bass notes that it does. And why it doesn't require gobbs more power than it does to perform the way it performs."

In chatting with Ian during the development of the EP800, the main reason he mentioned in using a sealed box was because if it were ported with the super low frequencies involved, it would be impossible to control port "chuffing" and noise.

So he went the sealed box route. In doing so, sensitivity is lost because you're essentially throwing away all the back-wave energy, so to get the sensitivity back up, he used two big drivers with dual voice-coils on each, wired in parallel. By doing that, he was able to extract the maximum amount of power from the amplifier because the impedance of the two drivers' dual voice coils was around 1 ohm. So we didn't lose out in sensitivity.

Regards,
Alan

Thanks for the information Alan.

Good info about the reason for the sealed design. I keep forgetting about port noise, as I never encounter it with my system nor at Mojo's.

Alan, I always really appreciate how concise and informative your posts are. Thank you.

How come no one has posted something like this to one of MY posts?
