    Those look great! Wonder when they will be available to us here in the USA.

      Oooooo, my heart was set on an EM1308 but this looks interesting and potentially can dig a little deeper. Will need to look into this a bit more.

      You wait for years for a 3” dome (other than the ATC and VM752/3 at mega bucks) and then two come along at one (well actually five if you count all four versions of the Bliesma).

        Nice!

        Sign me up for a pair - can cross-over at 350 Hz . . .

          I wonder if they'll come in yellow.

            Furthermore, HiVi has some other new drivers listed on the website as "Hi-end". There is a new pair of D6.8 style woofers and a pair of grilled tweeters with huge diameter faces (116mm, 130mm) that weren't there before.

            djg- I would go for a 3" Kevlar dome! Wonder if an 'eye-slit' doping applied would damp resonances....

            Later,

              Why is HiVi selling drivers that are shielded? They mention use in video applications, but who what video systems require shielding now? Maybe they sell to countries that still have a large number of old TVs still in use, but still seems odd to me that any firm would produce a shielded, modern driver.

              I'm guessing that, using a neodymium magnet, the shielding almost comes for free as you design the magnetic circuit.

                But I don't see neo magnets being used in the other ones I checked that have a shield. According to the description "...the shielded magnet structure allows the F5 to be incorporated easily into audio/video applications." for example. Shields were used for close proximity to tube TVs. That one appears to likely be a ceramic magnet. Maybe the shield covers ugly magnets, maybe they're double magnets to increase the magnetic field at the coil for increased sensitivity, but that F5 is only 86db. Why do they claim A/V application benefit? Seems moot at this point, even if it's just continuation of existing fabrication production lines. Shielded A/V drivers went out of need a loooong time ago, or so I thought.

                I see that the new 6.8B does say "A specially shaped, CNC machined steel cup completes the magnetic structure from the outside, creating a shielded magnet system with symmetrical flux density distribution along the gap.". But at least they don't make any claims about A/V use.

                  from the front they look like those Peerless GBS series drivers
