Philips AD1050/M7

[afroaudio]

Hi all!

Plenty info on the popular 9710/M8 available, but not much for this 10 inch cousin the Philips AD1050/M7 which I just picked up a pair of.

I am tempted give open baffles a go and have also read of a build someone did with a distributed port design by Briggs.

Hoping that someone here has had experience with these particular drivers or can suggest an enclosure that would work well for these.

Did find some measurements online also below which I think were made by member DrBoar from Sweden...

No experience, but the specs dictate either an OB or TL tuned to Fs/Qts' [Qts + any series resistance], which is functionally nearly the same WRT performance as Briggs cab and easier to build/tune.

I imagine DrBoar has some design details already worked out.

i have a ad4000m

same, for the most part.

these will sing.

paper voice coil former, so u might want to keep the power low.

less than 5 watts.

open baffle is good.

It's unfortunately hard to avoid relatively large enclosures or open baffles with most Philips FR units.

agreed .

Thanks gents!

Good to know that the AD4000M is basically the same driver.. at least there are others experiences here with this driver that I can read about. The 1050/M7 seems like a rarity.

I have been reading further but still find the options overwhelming:

Aperiodic
Large sealed enclosure
Interpolating between the Philips Monitor 8 and Monitor 12 to come up with a BR Monitor 10
Open baffle
TQWT

I am hoping that I can get away with a fairly simple build that can show off what these drivers are capable of. I also prefer a small footprint, space is at a premium here!

Amp will be EL84 push pull which should work nicely.

I really do not have any ready and measured stuff at hand. The driver at least does not have the sharp on axis rise at the high range as does the 9710 so a large closed box, or resistive vents or open baffle is what I would aim for.
