Beyerdynamic DT880 *closed-back* - Page 3

I just measured the port on my dt770's, it is 4mm in diameter. If that is 3/4" electrical tape then your hole is ~8x6mm. Something like 3-4 times more area. Agreed pads will probably affect the sound as well. Thanks.

Finally returned into to team "closed back". Here a pic of the interiority, as generally known, NoXter is too cool & lazy for ready-to-watch pics.



While I preferred the old 250Ω systems in a stock housing, I was not so content with my new 600Ω systems in such a vincinity, these were quick and warm, but lacked deep bass.

I must say, a DT880'2005 with 600Ω systems and closed back housing is a dream team, as it combines virtues of the DT880'600 (snappy, warm mids) with at least a slice of the DT770 deep bass authority.

Wow...

Has become my main can meanwhile. Wouldn't say it sounds overall better than my beloved big Alessandro, but it's at least on par, and much more comfortable to wear.

No worldclass allrounder, but it drags me constantly to the Drum & Bass kind of stuff.

it looks like all the housings on the models would interchange, any chance beyer would just sell the outside cover, heh & just swap to have a 770,990,880, heh

I wonder if someone already tried this mod on the T 1, this may give us an idea of what the rumored closed version would sound like ?

Nope, also the systems differ slightly.
I have my doubts. I can't imagine a more antithetic approach to things than tinkerers and highenders. Wait for a year or two, when real world people have put enough money aside for the T1.

In difference to the HD800, I am personally highly interested in the T1 though - folks describe them as a high res version of the DT880'600 with more bass authority. I was a bit discontent with the stock DT880'600 bass (but I can't live with the DT770/990 rumble), hence that "closed back" mod, which provides at least some of the T1 bass advantages.

Right, due to all the felt and tissue bestiary we have placed on the systems, they are much darker & warmer than the usual Beyer.

But if you just do the closed-back thing & pad exchange and leave everything else untouched, you end up with a nice mixture between DT880 (more bass) and DT770 (more mids, less bass), and a still overall very Beyer-like presentation.

Are you using felt? Also without the felt do you get the isolation?

The felt (or rather tissue) layers have nothing to do with isolation, nor are they inevitable components of the closed back mod. We just put some of them frontside on the system (under the stock foam circle thingy) in order to adjust the sound to our personal listening habits, which resides rather on the darker side of things.

nickchen what genres would you say these excel at? I've heard you mention D 'n' B and post-rock... What do you use these babies for.

Also, how did you get that all black beyer in the first picture. Can't even get the center part black with manufaktur.
