planar or ribbon midrange

[back]

hi everybody i am new to this.
i am looking for a midrange driver 250-4500HZ
do you have any suggestion?

[Chris Daly]

I would go straight for Quad 57 ESL's , properly
running,- it ( still !!) has the best midrange delivery for a
speaker which was readily available 1957-1982.

It won the best hifi product of all time award by Hi Fi News
and Record Review and is acknowledged worldwide
for its amazing breathtaking midrange ability.

However don't expect extremely low bass from it, but
it is never the less surprisingly good when positioned
in a room on a support which raises each speaker
about 50 cm. Also try removing cloth battons from rear of
the Quad , however will require some added space
positioning the speaker away from the rear wall if
cloth is removed

If its a midrange specific driver to fit in an existing
cabinet you might find Heils Air Motion Transformer
could provide a interesting result.

Cheers / Chris

hi chris i have a pair of infinity`s and i like the treble very much
but i would like to like to to add a midrange.

infinity on bigger models was using the emim midrange but it`s
hard to find (used)are expensive so i thought maybe
somebody here can make a suggestion.

i have heard good things about heil do you know the price range about their drivers?

[Chris Daly]

Hi back
It looks like Heil made a few models that I can see
namely the Heil Air Motion Transformer which appears to
do some midrange frequencies, they also did a model 5a
which was a tweeter from 1500Hz up.

Here is a URL to their site:

With all precautions of buying on Ebay - particularly
if you have not done this before have a look at
available items on Ebays site. You can get a very
good idea of what is available there and you might
want to buy as well... however as I have mentioned Ebay
read on please particularly if you are new to Ebay


Here is some general Ebay help:
Look carefully at payment terms - Paypal is recommended
Don't enter into bidding on an item where Bank Deposit is
involved in a foreign country the bank will charge you and
the seller for accepting that money - what do you think
will occur ? - he/she will ask you to pay that fee too. Now how
do you pay for a fee without incurring fee(s) again - see
the problem with Bank Deposit its never ending Bank fees
leaving your wallet !! Negotiate Paypal before bidding ends
with such sellers ( only offering Bank Deposit ) if they dont accept Paypal dont bid !!

Carefully check the sellers history , and what they are currently
selling - does it look **** or are they concerned describing
the item accurately ?? Don't go to sites asking to contact at
such and such a email address they are invariably frauds
- there is legitimate procedure for members contacting
other Ebay members. so follow that procedure. If you are
happy contacting that seller do so and ask and confirm
their postage costs before bidding.

Read as much as you can ,if you are new to Ebay- info such as Help with Buying items on Ebay's site it is all there to help you

thanks chris i am not new to ebay.

it seems that there are no midrange to fit to an
existing box other than heils.

only big ones like the b&g but they require a knew box.

[Chris Daly]

Yes difficult even with the Heils to perfectly fit
to a box designed for conventional drivers.
The Peerless midrange speaker used in the Gale 401
was a very low distortion device despite being
a cone driver. If you are forced to use a cone
midrange Kefs B110 was very good indeed.
I have built Kefs 1989 L/S 3 5a crossover from
a schematic on the internet and can say that
carefully constructing a crossover network to
match a driver as this design calls for , provides
a well researched and great sounding midrange device.

There is a huge interest in the L/S 3 5a -one of the
best sounding cone speakers available.

Janzen also made an Electrostatic driver that looks
as though it is a midrange device. You might want
to externally mount perhaps raising either the Heil
or other ribbon or electrostatic midrange above your
existing cabinet, you would lessen any resonances
that could interfere eminating from bass frequencies
( B&W DM7 was an example of a tweeter mounted
above a cabinet which worked very well ).
All depends on how far you want to go. cheers / Chris

Hi Back,
The size of the BG Neo 8 is similar to the EMIM . It can go sealed, dipole or what you want . Not 250 Hz of course but 500-700Hz
is possible. ( like the infinity sigma for example or REN series)
Cheers,

Cheers,

wow thanks i checked it out.
i can modify the xo al little to go for 500-700 hz
i have double 8"

do you think it would sound as good as the emit tweeter ? (i bed it will sound better than my current cone midrange)
if it does i mght use it for mid - tweeter to make it
a 2 way.

last question the sensivity 93db is real?

[inertial]

The response of the Neo 8 is not the most flat of the world, but it can be adapted with a pair of LCR trap ,IMO.
Sure, the sound is good.
Two way is possible if you can live with a narrow vertical dispersion.
I think 93 is optimistic, expecially post passive-eq/filtering maybe 90.
Cheers,
