;Why do I hear a Noise/Hiss in the IEM system?

<td></td>
−
The most common hiss that is referred to is caused by RF interference. An important step in setting up a system is to tune the equipment properly to ensure that external RF signals are avoided and hence interference is avoided.

The other hiss that is sometimes noticed is the internal workings of the unit itself. The body back receiver has inherent noise from the components especially when there is a low input signal. This phenomenon is not unique to Sennheiser but occurs across all manufacturers.  
+
; Two Sub1s or Sub2
 +
Two Sub1s have approximately the same membrane surface area as the Sub2, (180 square inches).
  
−
This internal noise is made more apparent when in a very quiet environment (like a recording studio) or when more sensitive earbuds (such as custom in-ear molds). From a practical standpoint once you have audio through the IEM system it will overshadow the noise from the internal components and most people will not even realize the noise is there.

The power difference is negligible (960 watts RMS compared to 1000 watts RMS).

Two Sub1s tightly coupled (stacked or side-by-side) should provide up to +6 dB SPL<ref> +3 dB from doubling the power and +3 dB from [https://blogs.qsc.com/live-sound/what-does-subwoofers-mutual-coupling-mean/ mutual coupling]. </ref> over a single Sub1 (118 + 6 = 124). The Sub 2 is 123 dB SPL. The SPL performance of two Sub1s should be similar to a single Sub2.
 +
 
 +
The Sub1 goes down to 40 Hz. The Sub2 goes down to 37 Hz (-3 dB). The difference is due to the larger physical volume of the Sub2 enclosure. Running two Sub1s does not change the frequency response.

Two Sub1s or Sub2

Two Sub1s have approximately the same membrane surface area as the Sub2, (180 square inches).

The power difference is negligible (960 watts RMS compared to 1000 watts RMS).

Two Sub1s tightly coupled (stacked or side-by-side) should provide up to +6 dB SPL[1] over a single Sub1 (118 + 6 = 124). The Sub 2 is 123 dB SPL. The SPL performance of two Sub1s should be similar to a single Sub2.

The Sub1 goes down to 40 Hz. The Sub2 goes down to 37 Hz (-3 dB). The difference is due to the larger physical volume of the Sub2 enclosure. Running two Sub1s does not change the frequency response.

L1 Pro16

The SPL output of the L1 Pro16 is 118 db SPL (124 peak). The output is similar to the Sub1.

Technical Data for standalone units
  1. ↑ +3 dB from doubling the power and +3 dB from mutual coupling.
