Bandor 50mm Project

inrank · 25th October 2007, 11:00 AM

just recieved a pair of Bandor 50mm Full range drivers, put them in some quick, small, cardboard 1.5L sealed boxes with some 'egg' diffusers for a cheap Omni-directional project.

does not sound bad for £30

i like the open spacious and relaxed sound, certainly very different to my Silver Iris coaxials

does anyone have any info on these? they have a sticker with the following-
DW 802
25w RMS
.75 912

along with a sticker with just '802' on it

Did you think about looking on their website? http://www.bandor.com/products_frame.htm

inrank · 25th October 2007, 11:28 AM

yes

but i assume these are older, they have the inverted surround (like the jordans) and the model numbers are different.

i assume they will have similar specs, but i was just asking if anyone knew if they were different

Little difference AFAIK regarding the box specs at least. Try emailing them for the definitve answer -as a small concern run by Ted Jordan's ex wife I believe, I imagine they'll be happy to help out.

The telephone number dates them.

As does .75 - inch diameter voice coil.

I used a 0.5" dia. voice coil unit as a TV speaker for many years, before this new-fangled NICAM stereo was dreamt up. It is now the first speaker connected to a newly built amp.

I assume you have visited http://www.bandor.co.uk?

Mrs Jordan(Ms Doreen Bance) has been selling these for many years. I wonder just how different they now are from E J Jordan units.

Edit
Ooops - late as usual!

hi, thanks for the quick reply, yes i have visited the site and emailed them aswell.

they seem to be very inneficient (as they should do compared to my 94dB silver Iris's )

i am really liking the Omni directional sound

voices seem to hang in the 'air'

DW stands for "double Wound" voice coil, Bandor also sells SW's or single wounds. The type you have got seems to be the "50ADW8"

nice drivers, still have a pair of them too. For fun you should try them just lying bare naked on the table for fun (well the drivers that is, not you) and sit close in front of them, doesn't go low but this way you will get a soundstage to die for, a bit on the small side but absolutely gorgiously 3 dimensional.

thanks, not sure where this idea is going really, was thinking of mabye using the Omni directional 'module' with some sort of passive bass part below.

iirc, the Wharfdale Linton's were about 86dB, which i have the bass drivers for (the enclosures underneath the Bandor boxes), could it be possible just to add a simple 6dB low pass on them at around 120Hz?
