I started out with the same speakers when i purchase the yamaha in dec 2008, same placement, no obstruction to the ventilation but why the problem started only now...i agree -30db is not that loud to begin with..

my amp just warm to touch now after I use 120mm fan at the side to blow air away from amp. before this can hardly touch it for more than 5 seconds for certain part.

if ur amp shut off everytime u reach -30db even its still cold, then I think ur amp is clipping.

Actually I think the volume db level is different as I have Yamana AVR back in 03 (6XX but I can't remember the model ) and my listening volume is about -30db to -19db but now I'm using Yamaha 1900 and the db level is from -23db to -4db with same speakers, so I think the db level is various for different models...

Look at the back of you Amp.

Are there any bare wire that is touching both the red speaker jack and the black speaker jack?

a word of precaution, you must quickily sought it out, whether its the speakers or amp.

bad and costly experience, my sunfire power driving the chario italy speakers, had similar problem, me unluckily same scenerio as yours, sunfire amp cut then very hot, stupid me that time no experience, still continue use,
later it blew my speaker (one side only) gave me a fright.

hmm.... woofer gone and also sunfire gone also, sent to one shop in Tun Dr Ismail, the Sharp dealer (yeap remembered JV concept) cost me RM1500 seems the whole row of transistors blew, and also the chario cast me 1k

Am looking for some advise from Bros. Thinking of getting an AVR to connect ps3 and dl content from pc to lcd tv, was looking at a RXV463 and Yammy NS-8390 (front) SPK 5/60 (centre & back) as am on tight budget and live in condo. Any thoughts? Thanks!

NS8390 - 3-way speakers should be fine for condo .what woofer you using?

I went to the dealer AVE in Chai Leng Park and run tests and turn out the left surround got problem maybe the electronic inside the receiver for the left surround speaker is damaged, the receiver still under warranty just 7 months old...the dealer sending it to Yamaha service to sort out and mean while i got a receiver for temporary replacement...

Think you refering to center NS-P60

wou... really think NS-8390 too big for condo ( individual preference thou'')
maybe can consider NS-125/210/310 series,.... looks kida cute for condo


how much the NS-8390 and NS-P60 ???

HHmm..have got history of complaints if you know wat i mean... ...Harvey Norman in the curve was offering the set (AVR + Speakers) RM3.1k at 3 yrs warranty...RM2.7k for 1 year warranty...i tot quite bang for the buck..

Added on July 11, 2009, 1:31 amActually was planning not to use woofer for the time being...as own preference is that front speakers should be able to handle...if bei tahan only get the subwoofer..any good budget ones to recommend??

well 5.1 spk package for 1k+ is a very good deal,
nope, haven't tested this spk series but i think yammy shouldn't be a problem at that price bracket, since all is yammy,go for the yammy sub too.
you'll certainly miss the extra oomph!!! w/o the sub
enjoy

ps .....have you tried mission 33i range and the likes of warfedale within the price range
