Which setup would be louder?

[Juniorkimbrough]

1. Peavey Nitrobass head pushing 350 watts @ 4 ohms
w/ 210 Peavey cab (4 ohms)


OR


2. Peavey Nitrobass head pushing 170 watts @ 8 ohms
w/ 410 Eden cab (8 ohms)



Thanks, sorry for asking so many questions lately. I'll be getting the Eden cab tommorrow so hopefully I won't have anymore questions.

The head with the Eden cab.

Almost identical, but with the 410 rig you have room to upgrade your amp and get more sound.

Doubling speaker area yields +3db.

Doubling power yields +3db.

Actually you have to multiply the power by 10 get get a 3 DB increase I believe.

No, you have to go 10x on power to get double the sound pressure level. 2x on power is 3db (just noticeable).

1) ashdown mag300 -> ashdown mag 410T deep cab, 185w@8ohms

or

2) nemesis NC-210, 2x10 internal speaker cab, 250w@4ohms

which one's louder? which one's better for on-stage monitoring?

May I ask. Why not get a 4ohm Eden 410?

Yep that's right. Presuming efficiency stays constant, doubling the wattage yields a 3dB increase. People can hear 1dB increases if they are expecting it and it's reasonably free of masking noises, so 3dB is more noticable than people give it credit for.

To double your SPL, you need to increase it by 10dB. Where efficiency stays constant, this requires 10 times the wattage.

If you doubt this, it can be shown mathematically using the formula:-

SPL = (10 x (LOG Wattage)) + Sensitivity in dB.

Go the Eden cab. You may need help carrying it around though. They're not light.

Because I'm buying it used.

Just got home with the 410 Eden cab and man does it sound good!

I hooked up both the 210 and the 410 and it does seem like the 210 is a bit louder but it's really hard to tell, regardless it sounds amazing.

The Eden has a nice punchy sound compared to the Peavey, but it might be because it is rear ported where the Peavey is front ported.

A big step up from the Peavey TNT combo I was using.

My Eden isn't read ported. It has a couple of shelf ports on the front, both above and below the speakers.

 

[Juniorkimbrough]

Mine is used and probably several years old, your's might be the newer version.....

 

[pickles]

Yours must be a 410T, which in many ways is a better sounding cab than a front ported 410XLT. The 410T is like an old SWR Goliath with an eden twist. One of the best sounding cabs of all time IMO. The only problem is when you gig with it, be careful about putting it somewhere that the rear port is going to fire into a big echoey void ... or you'll get boom. Try to keep the back of the cab within a few feet from a wall (but not all the way against it).

Save up your pennies and pick up a second hand WT-800 to go with it some time

 

[Juniorkimbrough]

yes, it is the 410T....

btw, here's a picture of my new rig in case anyone is interested.
