Z9 and speaker issues (help)

[Sinister]

Howdy!

I have a bit of a problem folks and I wonder if I could get some assistance. I am (have) installed the following system;

Sony VLP20 (awesome with the Z9!!)
138 inch Screen
Yamaha Z9
Yamaha Progressive scan DVD
Mirage 300W Sub
4 rear channel speakers - Boston Accustics VRi 585's (150 watts)

Here comes the problems

3 front Boston Accoustics VRi 595's (8 ohm's), 1 week ........Blown!
So I then tried
3 Sonance Virtuoso 833DR (pivoting array, 175 watts, 6 ohm's) 2 days...Blown!


The Z9 is AMAZING when it comes to power! The problem that I have is that I MUST have in ceiling speakers. There is no other way as the wall where the screen comes down in front of is all windows facing the lake. Is there anyone who makes a front set of speakers that can handle this kind of power? I have a drop ceiling and about 14 inches to play with between the trusses and was thinking of angling some box speakers behind a fake cloth tile....any other suggestions??

Sinister;

You shouldn't be blowing speakers like this unless you are really cranking the volume to very loud listening levels in a large room. I suggest setting all speakers to small with about 80-100Hz crossover setting. It is possible you are blowing these inwall speakers by having them attempt to play bass.

I always recommend people consider small bookshelf type speakers or as you suggest hide box speakers behind cloth to match a room decor as they usually outperform inwalls for obvious reasons (having a structural cabinet as opposed to drywall.

Thanks for the fast reply Gene!

I am cranking it up and in a large room

My room measures 30'x26'. The system was professionally installed and the guys who installed the system knew what they were doing and were very correct in reccomending the Z9 (I think I had one of the very first ones here in North America). I blew out both sets of speakers at approx the 5-7 DB setting on volume.

The Z9 has amazing power, but I always intended to use this power an that's why I went the big reciver route. What's better than sitting down with a few cool ones with the boys and blowing their socks off <*>.

Any suggestions on speaker setups that might be decent with the Z9?

p.s. I certainly am enjoying my Z9, before the official review, are you seeing the same thing?

p.s.s

It's the tweeters-mids that are blowing.

Well I am certainly not blowing speakers on it But yes it is a fine receiver despite a few things I am not crazy about which I will elaborate more in my review.

A 5-7dB setting on the volume is certainly cranking. I recommend looking into speakers that can better handle this power and again check your bass management settings to ensure all speakers are set to small. Realize too that driving a receiver to its limits can cause clipping which will also damage speakers. However, I don't believe this is happening in your case. I think your speakers are running out of gas before the Z9 even has a chance to clip.

It is difficult to make speaker recommendations when one doesn't know your budget and dimensional constraints.

Thanks again.


I don't really have much budgetary concerns, besides getting stupid and chasing the last little bit of performance that I don't care that much about (this is not my only hobby nor am I a fanatic, just want a real decent setup that I can crank loud when needs be). I think I'm into my HT system for probably 25-30 USD already, so that should give you a good reference point.

I have lateral floor trusses running perpendicular (left to right) to the sitting area wth 2'x2' ceiling tiles and about 3 inches of space between the botton of the truss and the tile. The trusses are 14' apart, Hope that's enough info

The system was not clipping at all when the blowouts happened, as a matter of fact it was sounding excellent. Just a particularily loud part of the movie came on (Underworld) and this seems to have done the trick.

Thanks again

p.s. It does suck that the voume control is not always visable on screen (I have my reciver installed in my back room).

Please check your bass management settings

I have the Underworld DVD and its full of deep loud bass passages. I strngly suspect that you're blowing your speakers because you are trying to play bass thru them. Most inwalls from what I've read cannot handle bass, especially the bass found in Underworld.

Here's a suggestion for some inwalls but as you see, they cannot handle deep bass nor alot of power.

I found where I blew the speakers is right after they jumped though the back of the subway train window (during the initial chase scene) and the first transformation to a werewolf that you see. It was right when he roared as he was changing that the speakers blew out.

I'm about 16 feet back from the speakers, I wonder if I put some boxes up there and angled them at 45% if they would image well enough?
