Hi Folks,

Would it be wise to get Norge 2060 or Gold 1000 along with Jamo s718

Heard that 718's have good bass in low end (looking for 2.0 floor-standing config in < 40k ).

Read reviews about it and made my mind.

What do you think, Please suggest if there is any other option in that range.

2060 may not do justice to Jamo s718,even 1000 I doubt as power req for this spk is 200w.

Greetings,

I used to own a pair of Jamo s718's. Yes they do indeed have nice lows, However they blatently lack certain vocal characteristics. The novelty of the low range will wear off very fast when you realise youre missing out on certain things in the sound. But I had a warm amp so- the norge might deliver far better since it's stereo.

The s718's FULLness of sound is something few towers in it's pricerange ( 24k ) can match - that is if youre looking for fullness of sound to fill a space without critical details in sound.

The norge will easily drive the s718's, they are over 91db sensitivity.

Glad to hear that, Thanks for the details :)

Thats what made me come up with this config.
NAD's have good vocals and punchy bass. Can they fill the gap ;) ?

I m not sure abt it.Even though sensitivity is higher,it can be due to more drivers as its only sound pressure.
It is 200w spk & may not sound detailed with Norge amp.
 
I'm afraid I do not understand what you mean by sensitivity is due to more drivers. The s718's have 2 midrange drivers which have very low excursion as med ranges should. Low ranges normally react in way more excursion and produce spl and lf. The s718's low's didnt produce much spl I noticed from the pair I had however they were quite efficient with lower tones and midbass.

As far as I know the sensitivity of a speaker paired with ohms calculate dynamically. Since the norge can pull off 4ohms and the s718's being 6ohms - I've tried them on 8ohm's system of 60w and they were easily able to deliver. Also some of the research which I did on the s718's led me to charts which pointed their sensitivity to be beyond their noted specifications, they went almost upto 94db which is very- VERY efficient. meaning even played on a 60w 6ohms amp will allow it to be driven easier than say something like lower wattage bookshelves with lower sensitivity.

Also their noted low range is at 40hz but they deliver down to 35hz from my own tests.

The problem they face is the med range drivers lack detail due to their massive 6.5 size, however the speakers were meant to be highly efficient "loud"speakers literally so it's great for events and big rooms. But not so much for critical listening.

How about the HK 3390 or Onkyo A-9355 ?

I had bought Marantz PM5003 for driving Jamo C405 last month. The 50wpc amp cost me 17.5k and I think does a decent job of driving a 89db sensitivity/140wpc C405. In my 12'x12' room, the amp can deliver an unbearable volume level without reaching its threshold. Marantz PM5003 could be one option for you.
 
@corElement-

Sesitivity is sound pressure produced by spk.If you use single driver,sensitivity will be relatively less than spk using similar 2 drivers.
 
Hmm..I still don't get the connection youre trying to draw between sound pressure ( spl ) and number of drivers being relational to sensitivity. If the sensitivity of a speaker was relevant to the number of drivers in an enclosure producing spl then how do subwoofers with 1 driver demonstrate a wide range of sensitivities across different brands and models.

Sensitivity is decibels, sound pressure is spl.
Each driver is individually sensitive.
Each driver produces unique spl. To produce spl a driver must travel, the motion/distance travelled by a driver is it's excursion.

Good midrange drivers will have minimal excursion as it shouldn't produce Low range frequencies. If a midrange produces high SPL it's a bad midrange driver.

Low range drivers are specialized in LF and SPL production. To do so they have high excursion to produce a tactile sound pressure as best as they can and pressurize a x b x c dimension of a room.

Sensitivity which is an electrical/electronic/phsycal property has nothing to do with a physical motion/excursion of a driver other than "standardize" the decibel rating for individual drivers.

for example take a amp, connect these speakers -

1000w speaker rated 94db = 124dB/1m
500w speaker rated 98db = 125dB/1m

Why does the 1000w have 1 db lesser volume than the 500w?
Because the 1000w speaker (94db) is 50% less efficient than the efficiency of the 500w (98db)

So effectively take the jamo s718 which is 91db avg on paper and 93-94db dynamic ( since each driver varies in application )...
Taking 90db as the reference point the s718's use less than 37% of the total 100% power required to drive a 150w tower rated 88db.

We havnt even taken ohms into consideration here because thats another thing all together, but what matters is that he's talking about 4ohm driving amp. If he were talking about 8ohms then it'd again be a different story.

SPL is relevant to a driver construction/design more than it is to the overall electrical efficiency. Has minimal to do with sensitivity or number of drivers.

He honestly dosnt have anything to worry about with a norge+s718 combo. Will never even be able to push it beyond 30%ish heck I wouldnt be surprised if he wouldnt even be able to push it beyong 10%

Thanks for info,

I was trying to compare single/same driver to multi/similar.
So 2 similar drivers will creat more pressure,than single.To do that it may need more power sometimes.
eg.

Spk driver with sensitivity (say 86db) if combined with another similar driver can improve sensitivity as whole spk.(upto 89db)
Again SW has larger drivers ,so cannot be compared with smaller drivers.

Speaker sensitivity - diyAudio

Again some spk with sensitivity(say 90db) may need 30w to drive & still some spk with simlar sensitivity need more power like JamoS718.

Ahhh,

yes full range drivers are different thing from multi range when it comes to amplification.

I believe it was suri or cranky or another someone... cant remember..
who explained to me that if done right, 1watt at 90db if completely efficient is all the sound the human ear needs.

You are right here & I was saying regarding Jamo s718 which need upto 200w
for higher sensitivity.
They havnt stated lower power reqd.

When I tested Tannoy F1 which need 25w as lowest,100w max, with Norge, I found 2060 was not sounding better even though it was compatible.:sad:
 
... the amp can deliver an unbearable volume level without reaching its threshold.

Unbearable in real terms :rolleyes:.
What do they cost

Glad to hear interesting discussions from Audiophiles
Keep them coming..

Yes, unbearable in real sense. If I try to turn the volume up further, I'm asking for trouble. Either I have to go see an ENT especialist or there is a an angry guy from the neighbourhood going to bang my door! :D

Jokes apart, I've tried my level best to pump up the volume to know as how much sound can this thing produce but I could never find enough courage to go beyond halfway past the 10'o clock knob position.

The amp cost me 17.5k and Jamo C405 31.5k, all b&w stuff, from Viola in Andheri.

By the way, not trying to poke my nose but you could give a serious thought to Jamo C405 as well. At 31.5k, it should be around 5-6k costlier than S718 but it's well worth it. You can go to Viola, D N Nagar, Andheri (W) and he will make you audition my combo.

I was watching Transformers 2 (given by a friend, normal DIVX 700mb movie) the other day and I was amazed at the kind of bass the speakers were producing. I haven't listened to serious HT setups yet but the bass my system produced was the best I ever listened before. And the good part is the bass wasn't coming at the cost of voice clarity. B-)

Thanks for your opinions. Will definitely visit the audition.
