112 bass cab 4ohm?

[itu]

I see the same question everywhere.

 

The big problem is that all we are advertised are watts, and impedances. But not:

- sensitivity (dB / 1 W @ 1 m distance) 

- loudness (dB)

- f response (say ±9 dB)

 

Yes, I know, this way cabs would be comparable. I suppose marketing departments hate that.

Even when they do spec the fr, I don't believe it

There is no real benefit in using a 4 ohm cabinet, and they are not that common. A good single 10 will more than suffice as long as it is sensitive enough,

I guess my main point and question is, if any amp is underpowering the cab, which i guess the elf running a 300w 8hm cab will be, then surely it will give more power and lows to a 300w 4ohm cab?

2dB more

...or less, depending on the sensitivity etc.

Ampeg is one of the more honest companies, and the 58Hz f3 is accurate, as is the 40Hz f10. They're playing a bit fast and loose when they say 'The Infinite Baffle design of these sealed enclosures produces vast amounts of tightly focused bass.', but nobody's perfect. 😒

Really? Those drivers must be something special, it's hard to model anything that small (per driver) with that response in winisd. Not doubting you, I know you worked with Ampeg.

Which reminds me... the sensitivity of an SVT 8x10 is 3dB less than a GRBass 2x12. It's real... I've tried them side by side.
