What size room are the JBL Stage A135C and JBL Stage A170 speakers good for?

The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:

Listening Environment* JBL Stage A135C JBL Stage A170
Near-field Poor Bad
Small Room Average Poor
Mid-size Room Good Good
Large Room Average Good
Very Large Room Poor Poor

(* Approximate Room sizes: Small < 100sq. ft / 9 m2, Mid-size: 100-220 sq. ft / 9-20 m2, Large 220-400 sq. ft / 20-36 m2, Very Large: > 400 sq. ft / 36 m2. Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual listening experience changes depending on floor height, room shape, surface materials, listening position, speaker locations, etc.)

In the following sections, we will get into more detail in order to better understand how the JBL Stage A135C and JBL Stage A170 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Power Range

Power range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.

A135C can handle a max power of 200 watts RMS from the amp the whereas A135C has a max power handling value of 150 watts RMS , 50 watts less than the A170.

Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters such as Impedance, sensitivity and system efficiencies.

Input Type and Bi-Amping / Bi-Wiring

A170 features 5-Way post posts which make bi-amping or bi-wiring possible. A135C has a 5-way post which doesn't feature bi-amping/bi-wiring.

Physical Specs

Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare JBL Stage A135C's and JBL Stage A170's external dimensions. JBL Stage A135C has external dimensions of 105.0 x 747.0 x 186.0mm ( 4-1/8 x 29-3/8 x 7-5/16inch) whereas JBL Stage A170 has external dimensions of 977.0 x 267.0 x 331.0mm ( 38-7/16 x 10-1/2 x 13inch) .

JBL Stage A135C is 872mm shorter and 145mm less deeper than JBL Stage A170 but it is also 480mm wider.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited. The base surface area of the JBL Stage A135C is approximately 1389.4cm2 / 215.4inch2 and base area of the JBL Stage A170 is approximately 883.8cm2 / 137.0inch2. The A135C requires 57% more surface area than the A170 which gives it a small disadvantage on placement in tight spaces.
