The Traducers

The traducers in both the LSr305 and the LSr308 have been improved for optimized damping. You can experience a better transient response, excellent deep bass and lower distortion. In terms of numbers, the two studio monitors have a trim control of +2dB, 0dB, -2dB. This provides perfect control of treble and bass.

Patented Image Control Waveguide

This newly designed waveguide accurately controls the sound that the speaker emits both in the vertical and horizontal positions. When you are listening, you can appreciate a neutral and accurate sound. This is room friendly and gives you more depth when recording. You will notice even the tiniest detail in dense mixing.

Connectivity

Regardless of whether you choose the LSr305 or the LSr308, you will be able to connect the audio monitor to a range of inputs. First, there is a balanced XLR. There are also 1/4 inch TRS inputs and a +4dBu/-10dBV input sensitivity switch.

Boundary EQ

This is another feature that has been upgraded. The new boundary EQ restores a neutral low frequency for different monitor positions. You can place these monitors on work surfaces and next to walls without affecting the sound. This new design also allows you to use the studio monitors new magnetically sensitive equipment.

Frequency Port

JBL’s Patented Slipstream low-frequency port works in conjunction with the woofer for abetter deep bass response. The shape is double-flared and is designed for better low-frequency extension and less turbulence.

The differences between the LSr305 and the LSr308 are very much based on the size of the studio monitors. We will start with the design.

Differences Between LSr305 and LSr308

Appearance

JBL LSr308 comparison

It’s obvious that you are looking at studio speakers, although the waveguide makes them look unique from others.

LSr305

The studio monitor is black. The matte finish on the front is a nice touch, adding to the design. There is a 5-inch transducer and a 1-inch dome tweeter made of damped woven Neodymium composite. Overall, the monitor is 14 x 12.2 x 13.9 inches and weighs 10.12 pounds.

LSr308

Similarly, it is black with a matte finish. The transducer is now 8 inches, but the dome tweeter and materials are the same. It measures 14.6 x 12.8 x 18.6 inches and weighs 18.9 pounds.

Frequencies

JBL LSr305 comparison

We have looked at the frequency range (the actual frequencies a monitor can reproduce) and the frequency response (the frequency range versus the amplitude).

LSr 305

This monitor has a frequency range of between 43Hz to 24KHz. Its frequency response is from 49Hz to 20KHz.

LSr 308

Being larger, you can expect a greater range and response, although it’s not that much more. The frequency range is 37Hz to 24KHz and the frequency response is 45Hz to 20Kh.

The Winner Is- The LSr 305

Maximum SPL

JBL LSr305 review

The SPL is the Sound Pressure Level. It is the highest level of sound pressure a monitor can handle before you notice the distortion.

LSr305

The peak SPL is 108dB, a little bit less than the sound of an aircraft taking off.

LSr308

The maximum SPL is 112dB, slightly more than an aircraft taking off.

Power

JBL LSr308 review

It is estimated that 60 watts are a good amount of power for an average-sized room in your home. The power of both of these studio monitors makes them suitable for home use or professional use.

LSr305

The dual integrated, custom Class-D amplifiers produce a total of 82 watts.

LSr308

While it also has dual integrated, custom Class-D amplifiers, the total watts is now 112.

Pros and Cons

The following pros and cons will help to give a clearer picture of the audio monitors before we offer the final verdict.

LSr 305

JBL LSr305

Pros:

  • This is good for entry-level monitor
  • Incredibly responsive bass
  • Amazing value for money

Cons:

  • Some people have heard a hissing sound from the amplifier

LSr 308

JBL LSr308

Pros:

  • Great sound detail compared with other brands of 8” monitors
  • Excellent dynamic range
  • No distortion at very loud volumes

Cons:

  • They are massive, so you need to make sure you have the space in your work area

The Final Verdict

Today, we are choosing the LSr308. That being said, if you don’t want to spend the extra money or you don’t feel you have space at home, the LSr305 is a perfect little studio monitor.

Overall, we felt the extra money was worth it because even then, the LSr308 is still an excellent buy compared with similar monitors. The monitor has the right amount of power and frequency range to produce a perfectly clear sound across a great array of music types. It looks smart, it has impressive technology and as well as being able to use it at home, it is a much better choice for professionals.
