Alright everyone, I've got another short amateur impression on the LCD-5 bass / dynamics vs the LCD-MX4 bass / dynamics.
I know many of you LCD-4/Z owners are curious to hear if the LCD-5 lives up to the LCD-4 bass and dynamics, and while I no longer own the LCD-4, I hope my impression can be somewhat useful.
So, do the LCD-5s measure up to the MX4 in terms of bass and dynamics? In a short answer, certainly! I'll go into detail now, starting with an explanation of my test setup.
For the source setup, I'm going from the RME Adi 2 FS XLR out to the topping A90 to power the MX4, and RCA out to the IHA-6 for the LCD-5. Using my trusty SPL meter, I volume matched both cans at 200hz and 300hz, to make the comparison as fair as possible. Since the MX4 is lacking in mid energy compared to the LCD-5, the 5 would sound a bit louder in comparison. So to even the playing field, I used EQ profiles for both cans such that when playing music, the average and max SPL from each headphone would be very similar. This, in theory, should reduce how much the mids interfer with the perception of the bass.
Once I was satisfied with my test setup, I started to listen to several different albums and tracks renowned for their drum and bass lines. I started with Fleetwood Mack - Chains, then listened to several Red Hot Chili Peppers tracks (including pretty much the entirety of SA-Jupiter!), Nirvana, Pantera, and various other rock tracks.
At first, it was difficult to tell which headphone presented bass "best". For dynamics, it was an obvious win for the LCD-5. Even with a purposefully lowered volume, the LCD-5 had more noticable punch to the drums and percussion. That being said, "best" in headphone lingo is extremely subjective, but I'll try my best to explain what I think "good" bass to be.
In my opinion, good bass in a headphone is like having your own personal kick drum, right next to your ear. Not in terms of loudness, but in terms of tactility. I had never heard this in a headphone, and never knew it could even exist until I heard my first LCD-4; it was a 2019 version, and it presented bass in the most incredible fashion. It could go deep into the sub bass, and it created it's own sound separate from the rest of the music. I found this same technical performance in the MX4, which is why I thought it would be a good idea to hold on to them until I could compare it to the LCD-5.
So, the million dollar question is, does the LCD-5 have this same quality in bass as the LCD-4 and MX4? In my opinion, yes. It stacks up quite well against the MX4. Let me explain:
As I stated in the beginning, I've matched SPLs of both headphones at the bass frequencies. This is important, because if you're the kind of listener who dials in their volume to a certain loudness level by ear, then you very well might be listening to the bass frequencies at a lower volume compared to the previous LCD cans. This would give the impression that sub bass is not as "present" in the LCD-5, but in reality it's because the LCD-5 has more mid energy. While this isn't a problem for people who plan on using EQ, I can see it being a draw back for people who don't.
That being said, I'll go deeper into the bass comparison. The MX4 has good, powerful bass when it comes to drum kicks. However, compared to the LCD-5, the sound blooms ever so slightly more, and doesn't punch as hard. This gives the impression that the MX4 has a deeper sound on bass drum kicks compared to the 5, and many listeners might find this as a more pleasing sound in certain songs/passages. The LCD-5, in comparison, will present the bass kick as a harder hit, with less bloom from the kick. In busy passages where the bass kicks might get lost in the MX4, the LCD-5 is ever willing to keep pushing those drums hits to your ears.
When it comes to sub bass performance, I had a harder time figuring out which can was "best", so I think I'll just give it a draw. Both headphones dug deep into the sub bass, and presented music with the same head-filling sound.
Before I got the LCD-5, my biggest point of contention was that it wouldn't have the bass texture and power I loved in the MX4 and 4. Upon my first listening with the LCD-5, I had the impression that it certainly did have the bass I was hoping it would. Now that I've done a direct comparison, I'm personally very pleased.
Alright, I'm done rambling with my subjective account. I hope someone was able to get something out of this!
Also, I've posted some images below of the LCD-5 driver and the LCD-R driver in comparison. The LCD-5 driver trace looks to be wider, and has a much finer finish. The LCD-R looks less mirror-y, and a bit more jagged.
