The magnetic depth can not be 16mm

kind regards

i wouldn't trust a single word on that spec sheet.

if you've already got them, go for it, they're going to be shit whatever you put them in, and at least you have some scoops :)

if you've not got them yet, save yourself the headache and get some used PDs or fanes.

Then go for it. Order some, measure tsps, then you will know. The fact that no one on this forum has bothered to try, and one of the most prolific scoop men of the forum is dissuading you should tell you something.......

Then they know nothing.....

if you on a budget loads of  new drivers around the 230/250 mark that will stomp it dead !! used  you can get pd186s/fane xb/beyma g550  for 300 a pair that will demolish those 

i will say tho in the flesh and when you pick them up etc they do look the business  

Ive got 2 super scoopers loaded with bishop sound bdp18 drivers and im very happy with them,

It may be that they wont last, only time will tell 

  The only Bishopsound drivers I have any experience of are some 21's that seemed to be an 18sound replica, they were well made but were also very power hungry, I seem to recall that for what they cost you could have bought a very good quality s/h 18", which is what I would have done...

  Have you a/b'ed your bishopsound drivers against say a PD1850 or Fane 18xb in the same cab?

Oh so students have been providing the results?

So you don't request the drivers to be made to your spec?

I'd expect them to be supervised by a member of staff. 

Universities often hire out their facilities to manufacturers. As well as providing a useful service it gives the students some real-world experience.

A lot of speaker manufacturers build their systems around available drive units.

It's usually better from the users' point of view because they aren't tied to buying spares from the manufacturer, with their extra mark-ups. And years later when the product is "no longer supported" you have more chance of getting a recone.

Problem is, tell tale sign of cheap chinese units are, huge qts or huge qes, with minuscule BL, which more resembles woofers for car speakers, as opposed to pro audio.

It's good they have a market I suppose but it's just Chinese drivers with union jack. Not my cuppa tea!. They had some unpainted unloaded cabs on the stand stand. Kind of looked like shuttering ply.  

There was a market for soundlab speakers and carlsbro so definitely bishopsound has a market

If you would would like to try some of our drivers please call Victoria in the office.

Best - Andrew

Maybe that's why there are a few discrepancies. Are the tools calibrated there?

We are very impressed with all of the students. They are working really hard and carefully which is lovely to witness... Andrew
