    I'm well aware of edge diffraction. But I like posing challenging points of view.

    1) the WAF solution is not to have any speakers or hi-fi on display at all. It's no good saying 'But darling, these speakers have very narrow baffles.' She doesn't want speakers in her living room, end of.

    For the WAF theory to be true the entire narrow baffle design would have to be aimed at that tiny sub-section of people who have a wife who will object to wide speakers but not to narrow ones. Whilst there must be some I would suggest it is hardly a demographic at all.

    2) There is plenty of research, mostly available on line, that looks closely into the effect the cabinet design has on the sound waves propagating from it. It is generally concluded that, all else being equal, narrow baffles image better than wide baffles.

    3) You can buy speakers that are absolute monsters and cost a fortune but still use a narrow baffle design. These speakers are clearly way beyond any WAF - pandering yet still use a narrow baffle. Why would they do that?

    As for Tannoys, the baffle needs to be that wide to accommodate a 15 inch driver, the fixings and the thickness of the side walls. I would be interested to see if anyone can produce any evidence that the baffle was deliberately made wide in order to improve sound quality. I'll bet there is none because I reckon they never even considered it. But happy to be proven wrong.
    No worries and noted. However, two things:

    In terms of the "WAF solution", I'm referring to the types of customers decent hi-fi dealers around the country have (such as hi-fi dave), and also abroad, with female partners who are happy to have proper speakers in the lounge, but nothing too obtrusive, and so tall, slim floorstanders of some description, often fit the bill.

    And I'd imagine if you totalled up those customers, worldwide, wherever there are such hi-fi dealerships, it'd amount to a decent-sized demographic - and trust me, manufacturers know that, and so cater for the demand

    Secondly, I won't dispute the imaging thing, but as Geoff points out, it certainly doesn't hold back big Tannoy DCs in that respect, as they image beautifully. However, I'm more of a scale/slam kinda guy, than an imaging freak, and I'm still convinced that baffle width has a key part to play in that, as well as obviously driver size.

    You should listen to a pair of these Hecos, in comparison with a quality slim floorstander, of overall similar dimensions, but with an array of smaller drivers, and you might 'get' where I'm coming from with wide baffles and one big (or bigger than normal) driver at the front, instead of multiple arrays of smaller drivers:



    The slam and scale those are capable of is much superior to the latter, although I don't know about imaging! Personally, I'd love to hear these babies:




    Do you think that Heco have bucked the popular 'slim' floorstanding trend for no good reason? I think not.

    Nice big, fat and wide... You can't beat it!

    How do you distinguish between the big driver providing the slam and the wide baffle providing the slam? All speakers with big drivers have wide baffles out of necessity, you can't fit a fifteen on a narrow baffle.

    So we can never listen to a big driver on a narrow baffle to test if it still has as much slam. We could put a small driver on a wide baffle and see if it slams more than it does on a narrow one, I suppose. I guess somewhere that the research has been done, pretty much everything about speakers has been researched and tested to infinity. So I'm not saying that a wide baffle does not add to the slam, I simply don't know and I'm wary of jumping to conclusions about it without doing the required reading.

    I'm not sure!

    I was just looking for a good pic of a large side mounted woofer to show that you could have your cake and eat it.

    Audio Physik do similar speakers.
    And my MBLs have an 8 incher mounted on either side of the cab.

    Never mind reading, it's LISTENING to them that matters most...!

    I understand where you're coming from. However, I'm just talking about as an overall 'package' - and in that respect, in terms of large floorstanding speakers, I'd always take a good wide, single bass-driver big 'un, over a good slim, multiple smaller bass-driver big 'un

    I have an aversion to speakers that have side or rear drivers or ports. To me it's just not right.
