I've been given a pair of Linaeum diapole tweeters by a very generous forum member, and wondered if anyone had any experiences of them ?

They used to use them on Genexxa bookshelf speakers, sold either under their own name or under the "Realistic" brand sold by Tandy, in the mid to late 80s.
Apparently they were fab sounding tweeters that showed the dome tweeters of the day, what treble reproduction was all about.
Here is a link to some on sale.
Have a look before it becomes broken

#3 Linaeum tweeters
I have a pair taken from the LX5 speakers mentioned above. The speakers were £30 in a Tandy sale, not long before their demise. The main issue with Linaeums is very low sensitivity - Noel keywood tested them in HiFIWorld many years ago as part of a ribbon group test (though they are not really ribbons) and came up with ~82dB/W IIRC.
I tried them in a home built speaker using Audax Ap100 as the midbass (the ones that were £5 each clearance fom Maplins years ago and about 85dB/W) and found the tweeters just too quiet. Not wanting to pad down the Audax I went with a dome tweeter- the Lins are on the shelf.
I see two pairs in the pic - if they're all yours parallelling them up to get a mini treble line source with 6db more output would def be worth a go...

#5 active HF solution
Give them their own amplifier, then the efficiency does not matter. Great amps are not that expensive and with the standard distribution of acoustical energy, the tweeter does not need to get 115dB loud.pre65 wrote:Sadly I only have the one pair.

#6 Re: active HF solution
I can try it with the 3 way active crossover. I might have a spare amp somewhere.rowuk wrote:Give them their own amplifier, then the efficiency does not matter.

#8 Phase align
Try and set them up physically so that they are acoustically in phase with your midrange BEFORE applying anything else. It is amazing how a fraction of an inch can screw everything up - it is even more amazing how much messing around with frequency response could be avoided simply by setting up the drivers properly.
