    I currently use a Be4016 Truextent in a Radian 951PB (1,4" version of the 950PB) on a modified H9800 together with one 1400ND. Network design wasn't too easy but now, I can tell ya. I'll not go back to the 3" drivers (2435, 435)
    I prefer the Radian as Truextent core as it has a 5 slit phase plug and is clearly superior above 12kHz to the JBL cores. But well..... this is a JBL forum.

I wouldn't rule it out as I am certain that it would be a worthy upgrade, but the 435AL sounds very good in the system already!

    Yep. That's all they could fit in the motor assembly. I'll stick with the fours. They're more expensive but they're worth it.

    I'm basically disgusted with their build quality. I've had a half dozen break at this point. They definitely are not robust like the legacy JBL compression drivers.

    They do sound really nice when they are 100%.

    Like JBL said though, they were designed to bolt into a loudspeaker at the factory and not take any kind of abuse outside of the system. Apparently that abuse would include simply carrying them across a large room.

    Hello 4313B

    Are you talking about a comparison between the TAD vs Coherent Wave phase plugs ??

    The merits of going with a five slit phase plug.

    OK I thought the Coherent Phase has 4 and the equivalent TAD has 5 slits. Didn't they look at this at one time or another. I figured TAD was the competition back in 2006.

    Looking at the Radian site, I can't find any info on the 951PB or any 4" diaphragmed driver that isn't a 2" exit.

    App. 100l tuned very low around 28Hz. Quite similar to the lower M9500 cab. Gives tremendous bass in smaller rooms.

    It's not on the website. The 951PB is the 1.4" version of the 950PB.

    Thanks Guido,

    Basically , I could reduce the size by 30 % compared to my BLS Reference SE ( Somerville Edition)
    That would be great . Maybe time to tidy them up and sell these . Call you soon !

    Rich

    BTW .... congrats on the new Pass and your Cabs are breathtakingly beautiful ... Love them German craftsmen !

    The guy from work who was with me in Japan to hear the E2, K2, 4338, S4600, etc is at CES today and sent this pic at my request. Said they sound good but couldn't turn them up loud enough to compare to treated, closed listening room in Japan.

    Superficially that looks similar to a K2 S9900 from the front, but it's a clever misdirection. The S4700 is a right angle box, not the voluptuous roundness of the K2. The drivers in the horns are smaller and of lesser materials. The woofer is less robust. The networks are not charge-coupled. The port and speaker connection unit are not a cast Al unit. The impressive cleavage of the K2 enclosure and horns is missing.

    I'm not disparaging it; I'm just making the obvious comparisons. I posted over on AVS that it's 55% of the K2 at 45% of the price, which in my book makes it a pretty good deal. A few forumites disagreed, writing it was less than 55% of the K2, but I do really think it gives at least 55% of what the K2 excels at.

    I posted these easily searchable component pics: two from the K2 and the last one from the S4700.

    FWIW, the mid compression driver is the same one in the 800 Array, and I don't recognize that tweeter.
