Huge !

[Madmike2]

Man this is the biggest tweeter i have ever had it weights 2 pounds easy and as you can see it bigger then the CD case. I think i am in love. Till the 4 10's show up.

What are these and what project are you putting them into?

 

[Chaucer]

Is that a Hi-Vi? If so, which?

TWEETER?

That's no tweeter! Here's a tweeter, all 12 pounds!

that is a cool tweeter. Do you know if the back plate can be removed ?
The purpose of this could be either:
- make it operate as a dipole
- place it a bigger designed enclosure to getter a wider frequency range (in the lower region). The f3 of this thing is rather high 1-2kHZ as I recall.

Unfortunately i dont think it will even be x-over anywhere near that. I had a couple suggestions and i think ill let it live above 3k. The morel runs up that far.

Nice ! too bad i cant afford it

Can you have a look and check if the back plate can be removed ? If crossing over as high as 3kHZ, you might be better of with a smaller planar or ribbon. Judging from the size of it your tweeter, it looks more like a midrange, thus beeming at higher frequences might be an issue, it might also lack a little in the very top end.

It is a mid/tweet. Beaming in a ribbon i have never heard of and ya the plate comes off, i am not going to take it off though

I am only crossing over so high to avoid the verboden region where no crossover is supposed to go. Kinda like space.

By the frequency response curves given i think the roll off near 18k wont bother me much. I wanted fast to match a fast woofer which matches my fast subs. Pretty low moving mass on the 10's i bought. If it all falls to peices and after a few months i cant get it sounding right ill rebuild it or buy a super tweeter and play with it that way.

 

[cph2000]

Because of the width and height of the ribbon, you will likely experience that the sound level will fall off as you move horizontally or vertically away from the the direct listening axis, this effect will be pronounsed at high frequencies. This is also refered to as beaming, e.g. the sound dispersion acts like a flashlight.

The old and very well sounding inifity Renaisance speakers had a mid panel much like the one you have, they however operated at frequences from 500Hz to something in the range of 3kHz, i.e. like a midrange. The infinity planar was a dipole device loaded by folded transmission line.
The planar midrange was IMHO the star of the show!

(sorry for my english)
hi all,
cph2000 I agree 99% with you. Maybe a BG Neo8 is more similar to the ENIM and a Neo3pdr for the EMIT. I have this drivers but the problem is crossing at 3Khz: the vertical off-axis is not the best, the same "problem" of the Infinity . And the neo3pdr do not like this "low" crossover point ( mine have no baffle and have a rear absorbing "line") despite a 24db/oct.
I like the "planars" but they have also limitations !
regards

 

[cph2000]

The HiVI planar looks VERY much like the infinity planar.

I actualy have the neo3pdr playing with a single 3.3uf cap, it sounds pretty ok. A second order xover did not sound good to my ears.

 

[inertial]

hi cph2000,
I have no doubt about your choice of 3.3micro ,it is respectable,
but the "cross" is high
About the HI-VI planar I think it is impossible (for it) to cover the range of the infinity REN (500-3000 Hz) ................
With the Neo8 it is possible, maybe not for very high SPL, but possible.
regards

This hi-vi will not go near 500 it is lucky to play at 1500 but it shows it running up into 18k plus so i should be ok. If it is a problem that is annoying or really noticable i will buy a super tweeter and re config the crossovers and use the hi vi as an upper mid. I already bought and paid for it so i think i will have to make it work. Unless Dave the Solen dealer wants to buy it off me


For what i paid LOL not gonna happen
