Default Is this really possible?

I'm searching for a small woofer (4") to use in multiples to cover the approximate range of 60-300 hertz in a very slim tower. My goal is high efficiency. I stumbled upon this driver..

Fane International Studio Series 5" Professional Full Range Woofer - 50W RMS | STUDIO 5FRK | Fane International

FS=58hz, Sensitivity 92dB. Is that even possible for such a small driver? Seems too good to be true.

It is a 5", probably possible.

Hi,

I think there is no way you are going to get 92 dB with that single
driver. Personally IMO the more sensitive the speakers are, the
crappier they sound. If I were to build really sensitive speakers,
I'd do it with PA drivers.

For me this is a high efficiency midrange:
Fs 180 Hz
Re 7.2 Ohm
Qes 0.59
Qms 2.70
Qts 0.48
Vas 0.93 dm^3 (0.033 ft^3)
Sd 94.3 cm^2 (14.6 in^2)
Mms 8.4 g

perhaps this transducer is helpful:
SPH-75/8
or
SPH-75/4
or

But I wouldn't expect good results in a very slim multidriver tower in general and also inside the range between 60 and 300 hertz.
If your goal isn't special design and only high efficiency, use the Studio 12L from Fane Acoustics

Look at the datasheet, the 92dB rating is obviously a mis-print.

How many "multiples"?

As you parallel drivers the effective sensitivity goes UP.

Look at some line array speakers...
...and why to only 300Hz. and not higher?

The pdf says 90.1 db/spl
