Interesting comment, Lars.  I took a good listen to tracks with good sub bass ("I'm So Lonesome I could Cry" form the Cowboy Junkies Trinity Session is particularly good), and I did not perceive any diminishing sub bass.  Again, only a cleaner sound, and perhaps better imaging/soundstage.  I did do the full mod, and really don't have the appetite to undue part of it.  Out of curiosity, is that half, in sections or how did you determine how much blu-tack on the circumference?

 

My setup may be different, too, as I've done the grill mod and the bass lens with a 3mm wool felt glue-sticked to the cup directly, which prevents the use of smaller pads/rings or sticky-taped to the cup.  (see picture).  I'm using the Alpha pads right now, stretched over the cups, but may try the Audeze versions later.  But, they are sounding the best I've heard so far right now.

LOL! Hello neighbor!

 

Wanted to add to my J2 experience, the bass and soundstage is A LOT better than the M11 once I keep the J2 on for a couple of hours. The warmth really opens up the sound, and boy does it get warm! Wish I could keep it on all the time. 2 hour heads up for a listening session is too long haha. 

 

 

Now I need to get speakers! The journey never ends

After checking your mod, I think that might explain why you don't hear a loss in sub bass as I (and others like ohhgourami) did.

 

Since you have felt where I and many others seal the pads to the cup with double sided tape, you will won't be able to seal the gap between cup and pad. This in itself looses sub bass because the space between driver and ear isn't airtight (that's my theory at least). This could be why you don't hear any difference. This is a possible explanation.

 

Another possible / additional explanation could be that you are using a leather pad, while I (at the time I tried the full blu-tack mod) used the Audeze "vegan" pads, which are physically softer and delivers a softer sub bass than leather / pleather pads.

 

I get a significantly thighter sub bass with the HM5 pleather pads, than with the "vegan" pads, so I might not hear the same difference with the present pads I use where I to do a complete blu-tack mod.

I've never seen this "bass lens" mod before. Anyone have any more intel on it?

On my end, I haven't done any of the mods yet, but I did pick up both flat and angled pairs of the sheepskin HM5 earpads during a recent visit to Canada.

I don't know when I'll get to install them, but just from the look and feel so far I'm a big fan. I'll try to report in when I have a listen.

Literally all i did was take felt from my Mr Speakers Primes, and put them infront of the Alpha Pad on my 6 to lower the treble, which would filter highs, and let bass pop out better. That was my so calles Bass Lense. At the end of the day, i thought Vegans sounded a butt load better.

I have done a bass lens mod and reported about it in this thread quite a while ago. However, the felt disc didn't cover the cup-pad assemply area - just the driver leaving a hole for treble and mids.

 

Depending on the thickness, a bass lens will filter away treble and upper mids or everything above sub bass if it's practically solid (for instance thick foam).

 

The advantage of the HM5 pleather (and most likely real leather) pads is bass quality and dynamics. Drawback is slightly reduced resolution in the mids and slightly more treble. However, the drawbacks can be fixed if you add some felt or other fabric to the inside of the pads (in order to prevent reflections from the leather).

That's a pretty cool mod you got in there! We'll have to give this one a go with Pro iCan presto!
