All user reviews for the Eminence APT:80

I bought a pair to replace Piezo in columns 2x38 KOOL SOUND (BBX 215)
Used primarily to techno in a 3-way soundsystème.
Filter matched 2-way cut to 3.5 kHz.
Tweeters hold up well and rendering power is light years away from a piezo, while remaining the same size which allowed me to avoid any modification on my speakers.

SOUNDS

The frequency curve is neutral.
The highs are fine and clean, burr-free!
Has a slight hollow of my setup because there is nothing between 38 and 80 APT but has a little catching up the equalizer and the sound is good!

OVERALL OPINION

I use it for almost 1 year and I am very satisfied! The difference with piezo well worth the 23.90 euros! Only for those who want to like me, do not forget to buy a passive filter suitable for low-end speakers like mine are not equipped!
What I like most: the price, the sound and the fact that they are the same size as the piezo '' bullet ''.
What I like least: For the moment I do not see ... can be a bit aggressive if you tend to push the treble!
Excellent value for money!
If I had to take small acute for single use without taking my head, or replacement piezo I would do this election recess.

Here are the CHARACTERISTICS of the tweeter

Impedance: 8 ohms
Power Rating (18dB/octave)
45Wrms@3.5kHz
85Wrms@5.0kHz
Resonance: 2.5kHz
Usable Frequency Range: 3.5Hz - 20kHz
Recommend Crossover: 3.5kHz
Sensitivity (1W @ 1m mounted to test horn): 105dB
Diaphragm Material: Phenolic
On: 0.15mH
Re: 6.3 ohms
Depth: 1.57 ", 40mm
Weight: 1.5lbs., 682 kg.
In my opinion the performance of a 105dB/w/m can inflate all the same.

SOUNDS

This tweeter replaces trs out any piezo tweeter grace these dimensions.

The sound is not great but still trs honnte although I find it a bit aggressive. The directivity is short.

OVERALL OPINION

Tweeter reasonably priced and convenient to rebuild low-end speakers. Or even to make Creations home.

For speakers of good powers board I use several.

A note that the replacement of membranes available in case you with the nags jou: p

- What technical specifications motivated your choice?
the case of an EMT 133 (attandant in the new membranes)

- For what purpose?
currently mounted in acute reinforcement in place of piezos in Cerwin Vega V32

- What amp / What configuration? ...
reinforce the tubes 2 inches in cerwin / also tried in a game of rythmic (too aggressive)
pousss crown by a DC-300A

SOUNDS

- The curve frequency drives is it neutral enough?
bench with a break-directional active and aggressive front is then mounted on liabilities (as amended) of cerwinV32 whispering that it's more broken ears

- Stereo image is good?
It depends on how the heads are placed when it is otherwise it's quite possible sympathoche

- The sound is clear and prcis across the spectrum?
yes in my config it's going to complete the ca 2 inches without being too aggressive

- The dynamic is it respect? ...
heuuu compared to the fire "emt-133" carrment .... no one feels the least when a half inch even as he announced a spl equivalent

OVERALL OPINION

- How long have you use it?

8 months now

- What is the particular feature you like best and least?
the + +: Cheap
...... Mounting threads can be screwed on quite a few other tubes (with adapter)
Ca ...... seems to be as strong as the EMT133 (we'll see over time)

Cons: bha ... the thread of the square flag plastoc can (I have glued with AUTOJOINT blue)

- Have you tried many other models before acqurir?
yes I have tried many

- With the exprience, you do again this choice? ...
bin for 34 with the pavilion's not ruin this remake so I choose reinforcements to complete a treble chateau low meduim and breaks cheap (when it breaks )

= characteristic impedance: 8 ohms
Power filter with 18dB/octave:
45Wrms to 3.5kHz and 5.0kHz to 85Wrms
minimumCrossover: 3.5kHz
Sensitivity: 100 dB +
Diaphragm: Phenolic

Very good little tweeters, barely more expensive than piezzos, and much better!
Mounted
1 / on Small Satellites / returns of 200W rms with Eminence Delta 10 inches
and well-filtered at 4 KHz / 18 dB 2 / mediums on facade 300w (PE32 12p B & C), in addition to cuts FCR 1p, filtered at 6 kHz / 12 dB
in 2 cases more than the correct result, even fabulous for the price.
This tweeter very advantageously replaces any piezo tweeter, thanks to its dimensions.
In addition, membranes replacements are readily available ...
should any feedback would have exploded!


SOUNDS

The sound is not comparable to the 1 inch or B & C
but is very honest (a little aggressive, high directivity).
Very nice on vocals. Well take power.
The frequency curve is sufficiently neutral.
The stereo image = all depends how the heads are placed,
when it is asked is pretty cool

- The sound is clear and precise across the spectrum? in my config YES
- The dynamics are respected? = Roughly YES


OVERALL OPINION

For how long have you been using it? 3 years

Have you tried many other models? yes

What thing do you like most/least about it?
the + +:
Cheap can be screwed on a lot of other horns (with adapter)
and AC looks to be pretty solid. For good speakers Powers
I advise to use several.

Least: none

- You do again this election? =
YES, treble reinforcement, without any hesitation excellent ratio Q / P
The ideal configuration for me:
in small two-way speakers with bass mid 10 "subwoofer and 15", you will have a very small system returns agréble ... and cheap.

Great tweeter considering its price. You don't have a big budget? Don't look any further! Almost as expensive as the piezo tweeters I formerly used but way better...

SOUNDS

Very pleasant sound for vocals, string instruments and even wind instruments (I used to hear a lot of symphonic music). Very good power handling. Can be mounted on 250-watt loudspeaker systems or even more with a well set crossover (cut-off frequency at 5 kHz if you use a 2nd order crossover).

OVERALL OPINION

Ideal for compact 2-way loudspeakers with a low-mid woofer plus a 15" subwoofer. This setup provides a very pleasant and affordable compact system.
