SR60-Mod - Page 171  

post #2551 of 5003

Are you using it with an amp? The amp battery could be low. Happens all the time with my PA2v2

What kind of felt did you use to damp the driver ? Instead of a large, siver blob in the centre of your headphone, you should now have a large, ugly blob with something furry growing on it :)

Nah my ears are pretty big, they also stick out a little bit. Still more comfortable. You must have HUGE ears lol, or you're just wearing them wrong.

I imagine that some would think differently, but what I find is that soundstage increases and bass decreases as you go up in pad size.  That is a blanket statement, but that is what I hear.  By using the mods in this thread, you can offset the loss of bass as you go up in pad size - to an extent.

 

With east indian rosewood, and 10 holes, I find the quarter modded comfies bassalicous, but lacking soundstage - fun, but not for serious listening.

 

With the bowls, I get the best bass, with a good soundstage.

 

With the jumbos, I get the best soundstage, with good bass.

 

When I go back and forth between the bowls, I wish I could have that bass, but the soundstage of the jumbos has me.

 

I use the jumbo's all the time now, and never miss the bass of the bowls, until I listen back to back - so I stopped doing that!


You're right.  It's a tradeoff between soundstage and bass.  The bowls win the "happy medium" compromise for me, but the price and the concave top irritate me.  The soft sidewalls leak bass like a sieve, which is why bass fanatics love the flats and those who want an airier, more spacious presentation go for the jumbos.  It's also why people apply electrical tape to the bowls to get better bass.  It's an inelegant solution.  I'm looking into making a circumaural pad that uses leather to trap the bass so the ear can be further removed from the driver without shifting the tonal balance toward sibilance.

You must have big ears, too - it seems that several of our comrades prefer the bowls for comfort. Weirdos :)

Have you got a buzzing yet?  Vented drivers, particularly on plastic Grados, get a buzzing during heavy bass.  It gets worse when you move to aluminum shells, where the effect is even more distressing.  It's the center of the driver, where the magnet and voice coil sit, getting hammered by drivers that now have plenty of airflow.  I fixed my issues by slapping on plenty of Dynamat.  I doubled down on the stuff and got sweet relief.  Much as I discovered on my loudspeaker system when I augmented by 15" woofers with a pair of 15" subwoofers and a pair of 500 watt  subwoofer amps, the jump to a more dynamic experience brings out the weak links in the system.  In a truly dynamic system, you can't have any such weak links.  This is one reason to felt the drivers in the first place as doing so covers up the inherent issues with plastic air chambers.  Of course, the price of doing so is a much more limited bass, but as bass is what makes you want to throw plastic down a stairwell, it's a tradeoff.  When I upgraded the bass on my loudspeaker system, my speaker cabinets went crazy.  I failed to secure a subwoofer and watched it shoot out of the cabinet.  Even when I resecured the driver, the cabinets had to be reinforced to keep them from creaking as if the world were coming to an end.  These cabinets are six feet tall, so I had to go out and get a wall full of MDF to turn them into sound castles.

 

If anybody has an SR325, please contact me if you want to help me get objective feedback about the effect of lining the aluminum with tonewood.

Here's an idea I came up with for semi-open Grados.  Let's say you need more isolation but you don't want to go closed entirely.

Saturday Night Special.jpg

I'm tentatively calling it the Saturday Night Special because it looks like the cylinder on a 38 and you can sneak it into the rear chamber of a plastic Grado.  It ought to be illegal because it converts your plastic Grado into a snub-nosed woodie.

Load the Cannon.jpg

It's just the right size to act as a plug, filling the cavity of the air chamber, though its sound holes are obviously designed to vent as much HF as possible.

After trying this out, I'd definitely say it blocks out a certain amount of sound without making everything canny.  For absolute isolation, you'll still want to dive deep with veritable runway clappers but short of that, these make an effective compromise.
