Dali Kupid speakers on my Pioneer a-c5?

[Jonah_Lake]

I just had a listen to the new Dali kupid. WOW! I tried it next to the Oberon 1 and 3 but prefered the Kupid. My problem is that it's 4ohm speakers and I have an old Pioneer a-c5.
What problems could appear if I combine these two? Thanks

The A-c5 has these specs:

Power output: 40 watts per channel into 8Ω (stereo)

Frequency response: 2Hz to 160kHz

Total harmonic distortion: 0.07%

Input sensitivity: 2.8mV (MM), 200mV (line)

Signal to noise ratio: 85dB (MM), 105dB (line)

Output: 200mV (line)

Speaker load impedance: 4Ω (minimum)

And the Dali speaker:

83 dB @ 1m for 2.83 V

4 Ohm

103 dB

2,100 Hz

2-way

40 – 120 Watt

Do you listen at high volumes? If not, you should be fine - if you do, the amp looks as though it might not be ideal. Too little power with high volumes can be far worse than too much power.

the sensitivety is the problem, old speakers were all above 100db´s, and not meaning they were good, but at least sounded as better as they could, buy some cheap 80´s or 90´s Pioneer and you´ll see, CS reference, to 40watts the 140 watts DIN or 190 watts DIN

He's not asking for advice about buying old speakers...

I just had a listen to the new Dali kupid. WOW!

Take your Pioneer to the shop and try with the speakers . Should be Okay

 

[Al ears]

He's wrong about all old speakers being over 100dB as well......
The Kupids should be fine with the Pioneer however only an audition will tell.

Just buy a pair and return them if you don't like them

I know Acoustics energy ae 100.2 cost exactly the same in denmark, a little less in uk

I would def take a listen to them to

Both can be had here

AE 100.2 has higher sensitivity, bigger woofer and are 6 ohm

Good call. The Kupid look cute but that is a very low sensitivity and 4ohm rating, so even less sensitive relative to 8ohms nominal.

Those AE look better suited to price appropriate electronics.

I had a further look on the Pioneer specs and it does state speaker minimum load impedance: 4Ω. It should be OK!

And 40W into 8Ω will be roughly 80W into 4Ω, way beyond what you can play in a living room.

Indeed

80 watt is okay and you can play that do to the low sensitivity

Kupid replaces dali spektor, spektor 1 same size woofer

The amp is not 80 watt in 4 ohm, just about no amp can double the power in 4 ohm, even high end amps doesn't do it but very close, wiim amp pro 59 watt and and 117 watt

The old spektor 1 is 82 dB (2,83 V / 1m; 500-5.000 Hz)

50 watt at 2 meter distance is okay but not super loud (my speaker are no more then 85db ish) but should be okay, with 100 watt pr channel is loud but not party level or in any way close to a live rock concert or techno part

40 watt pr channel and 87db is louder then 82db sensitivity + 80 watt

Spektor 2 is measured to be 84db senstive

if wanting to connect both 4ohms and 8ohms at the same time with a pioneer amplifier or any other impedance but with a 4ohms speakers ,

first you´ll be happy with the sound,

after both amplifier and speakers will be damaged no matter if you listen loud or low,

i think i know a thing or two about Pioneer amplifier, my first was a 60´s receiver with turntable, both work today and i´ve seen better amplifiers gone bad because impedance wasn´t respected,


i´m still using a , well two pioneer amplifiers from 89 and 94 allthough both came out in 89 but sold till 97,

one of them at least, the A-757mk II, 120 watts a channel(i think it´s 90 each) they say, i do not know in other way i put there some 120 watts speakers from JBL and they can´t handle not even half the volume power,

for those who know them and think they are all the same, try to open a A-717mk II and then tell me if they are badly built compared to new good amplifiers between 1.000 and 2.000€ or if it´s equal to the A-717,

have some 5 amplifiers 600´s and 700´s all MK II , not the same as the mk I and not all released in the same year or built the same way ,

try a A-676 the last that came out and compare with any other from the same series,

or even this, being a fan of naim amplifiers , this last built with a diferent size all black and all say it´s good, well if it´s good i have the best amplifiers ever built, i have some in reality

80´s in sensitivity is a very low value but you´re right 86db will sound louder than a 82´s db, only the amplifier also matters,

when speakers say from 10 watts to 150 watts amplifier, doesn´t mean all in-between sound the same,

some might sound really bad, but i think the manual knows better , as the amplifier referred from pioneer in my country weren´t that good,

but also had a Sony ES that came out in 93 and said in hi-fi engine manual, different from mine, "this manual is for all sony xxxES amplifiers except U.K. and Portugal"

some are different for the better in a few countries, in the past i remember also from Sony ,only in U.K. had the specifications that were prized ,the same happens to different cassette decks in different European countries or after the limit of what´s considered Europe , a lower reference has top quality. A example,

To end, i would respect values limited by the brand, i´ve seen a lot of problems related with that, i am using a A-91D and it´s 6ohms minimum speakers, some younger men told me, "no problem you can use 4 ohms speakers" but i follow the brand´s advice as from the same year with a bit less power and sound quality,

i have them able for 4ohms speakers . they will work just fine with one set of 4 ohms speakers if not and added some 8ohms speakers at the same time, will sound amazing better but one day,it will happen both amplifier and speakers will Kaput,

just my opinion and some experience, i´ve seen it happen in different ways when not respecting values the brand as in it´s manual .

As in the catalog says 150 watts a channel , total 300 watts at 8 ohms, loud , but it´s about home amplifiers in a party in a big room will burn after many hours giving sound,
some have security systems that will cut off the sound when too hot, but i´ve seen also they still working just fine and already on fire, as professional material is totally different,
also find not correct amplifiers and speakers each informs the buyer in different measures or scales, not being possible a correct information to the buyer
