    Any way of telling them apart?
    The 4645 I have been offered comes with reconed 2245H's, but I would like the 25 Hz ones, of course!

    4645 (2245) have 3 bass ports and slightly different Dimensions than the others (and I thought it was tuned to 35 hz and not 30, but I may be wrong)
    4645B (2242) have 2 bass ports (25 hz)
    4645C (2242) have 1 bass port (25 hz), otherwise the same as 4645B

    It is a pair of the 25Hz 4645 with 2245H, so it should be the best possible option for HT, I'm a lucky guy!
    The seller wants to sell both at once, and while the price is very reasonable, I did not intent to buy two, and did not plan on putting two of those in our living room...

    I could sell one on, or keep both, but what to do?

    Keep both if you can squeeze them in. You may need a few to help eliminate room nodes.

    This ought to be moved from DIY... Well...

    I should be able to, the wall is 22' by 10.5'... (675x322cm)

    Although the WAF-factor might not be the best on the 4645, two have been approved...!

    I made a Cad drawing of how I plan on making the shelves and place the speakers:

    Should be no shortage of bass with both those 18s corner-loaded like that.

    True! But that's the recommendation of a true professional here in DK (and the seller), he sets up theaters and have been doing it for decades.
    You should see what he has at home!!!

    (I would love to put up a link or pic, but I would never do that without concent from the owner of the pictures...)

    Talking

    Just a little update:

    The two 4645 (the one's with 2245H!) have arrived and I love them!

    But I needed something to drive them, something worthy.............
    So a JBL UREI 6260 have been purchased, I couldn't be more pleased!

    congratulations!

    I think at you did make the right decision to buy 4645 with 2245h
    I donīt think at you will blow the 2245h before the front speaker you are using with them

    are the surround good on the 2245h woofers?

    If you run into sub amp headroom problems, another 6260 will likely cure the problem
    (one amp bridged per 2245). An impressive setup!

    Hi Ari

    Both 2245H have been serviced recently, surrounds are mint!

    Grumpy, I don't think that will be necessary, That would mean upgrading everything else in the system, and downgrading on the personal front from family man to single again ;-)

    I must say that I love the setup!

    Although many will not classify a set of 4645 with a 6260 in the living room as a "subwoofer", I am fortunate enough to be able to do so.
    I am not a seasoned audiophile, nor do I possess the skills and ears to give you a qualified review, but I can share my personal experience:

    I hear a lot of different sounding deep bass compaired to conventional sealed subs.
    I am used to the sealed design, and had never really considered the "one note wonders" critique, but I am astonished that the sound guys actually put that much work in to the LF and ULF sound...
    The whole setup (4645 + 6260) seems to have a feeling of effortlessness about it (it bloody well should, I know!!) again compaired to classical small volume sealed subs.
    Compaired to the 4645, most small sealed subs are like having an illtempered bulldog laying in the corner growling, whereas the 4645 setup opens up the very bottom end without compromising quality.

    I try to have the system balanced, and I don't turn the sub voulme up, just because I can, and they do provide that extra dimension even at very low volume and I love it!
