I have just seen on Artcoustics FB page www.facebook.com/artcousticspeakers that they have launched a new speaker with the text: "If you have a project in a large room, club, commercial venue, or just a client that likes to party..then you need to see and hear these!"

Hi all

i think I am going to sell the bowers and Wilkins CM9 which I have blown a woofer again and go for a set of beolab penta 3

they have four woofers per speaker and also the technology to stop clipping and distortion which should keep the room looking smart and give great sound.

now the hunt begins and then possibly amp repairs and reforming.

all good fun

I had 6 penta´s playing at once before. My neighbour never complained, couldn´t hear the knocking on the door or the doorbell ;)

A wise decision to go for the Penta's. I have a set in my Bar/danceroom. Not the Lab's - but the Beovox Penta's hooked up to a Beomaster 6500 (with a new set of caps).
I had a party this weekend - and they were playing LOUD.
Some of the guests, who can be considered 'audiophiles' and usually a bit critical about B&O were really impressed. They tried to turn it up at full volume to see if they could hear any distortion or 'clipping'. None of that happened. The amp played loud for 5-6 hours with no problems.

One of the very popular tracks that night was this one - by a Danish artist called 'Lykke Li'. Good for testing the bass 😁 

My personal bet is that you'll either destroy those too, or not be happy. What you want to do is not what home audio is designed to do, unless you go with a pro audio solution I suspect this will be an endless loop.

I totally agree with you Jeff and that's what I said in my first post! Penta's are old, old, old - it would be like dressing Prince Charles in skinny jeans and Converse and expecting him to out do the b-boys. Just ain't gonna happen. You NEED pro/club/broadcast speakers for your environment!

With all respect,Jeff. I don't see why he should destroy those too...

This is what he wrote:

 The music room is basically my own personal nightclub with disco lights smoke machine and very loud music. I don't want big disco speakers I still want warm quality. Sound but the ability to turn it up loud. Without the speakers telling me off. Any thoughts?

Of course, I don't know if Seanie's 'personal nightclub' is open every night of the week...
If so - Then he would certainly need some Pro equipment...

But - if it's a room only used now and then (perhaps even every weekend) - then the Penta's would do fine.
Yes - B&O is home audio - but it is build to last.
As we see here on Beoworld, people have audio equipment 40-50 years old -or more. With some TLC (and some new components now and then) they will go on for many years.
Seems like Seanie knows what to do, if he finds a set of Penta's. If they are playing now, after 20+ years - then some new caps will probably make them play the next 20 years or more.

Go back and read his posts, how many drivers has he destroyed? How many times has he forced a system into thermal shutdown? He's been farting around with inappropriate equipment for what he wants to do performance wise for quite a while, and still hasn't found anything he can't either blow or make shutdown. You think Pentas with 4 5 inch woofers each are going to handle the SPL he seems to require?

It's his room, he can do what he wants of course, but the only thing that's going to survive that kind of abuse is pro audio gear, stuff you can turn up to 11. It's like saying I really don't want a truck, but I'm going to use a succession of sports cars to try and haul a huge trailer. Just because you don't want a truck doesn't mean you'll ever find a two seater that will do the job. Reality can be a harsh mistress. And it doesn't matter how often in a week he does this, it only takes a short period of time to stress a home audio component acting as a pro level system beyond its limits. I've seen it done in less than 5 sec with the right kind of abuse.

I have read the posts Again... Did he destroy any B&O speakers..???

First of all I had some lab9's which sound perfect but cut our with today's modern music which is full of bass and due to the height have to be turned up loud to compensate for the low listening height, these ended up in my lounge as prt of my cinema setup.

I then built some fake insulated walls and bought some lab 12-3 which looked amazing but did not quite cut it for me and the volume did not make it high enough before protection mode and the bass would cause them to turn themselves down.

Next I decided to try something else, I purchased a rotel amp and some bowers and Wilkins speakers Cm9's these speakers sound very good and suit the room, i also make a cable that enabled the amp to switch on from the beosound triggar, but I have replaced the woofer in them three times when music and the bass making the speakers unhappy.

All in all the lab9's sound the best in terms of quality but cannon take the volume.

The lab 12's were amazing lookin.

The CM9 speakers sound excellent but not as deep as the lab9's nd have no built in protection to avoid overdoing it.

What I read is, that Seanie has not destroyed any B&O speakers. Some of them turned themselves down for protection...

He did destroy the CM 9's hooked up to a Rotel amp - because there was no protection...

And here is his latest comment:

How many drivers has he destroyed? The ones in the B&W CM9's...
None of the B&O's - as I read his postings...(correct me if I'm  wrong)
Distortion and clipping kills drivers... - not high volume alone.
A 2 x 25 watts amp can kill a set of 150 watts speakers under the right (or wrong) conditions. (I am not saying that his Rotel is only 25 W - just an example)

I hate to repeat myself - so please read my post above again. This is my experience with Pentas.
I guess I could have killed the Penta's - if they were hooked up to an amp without any protection circuit  - but they're not!
They can play really loud - for years and years - and they have done it. Believe it or not.
Seems like Seanie want to give it a try... Why not..? 

Pedantic aren't we? Thermal shut down on B&O products, did you miss that? He's been given plenty of good advice on how to actually solve his problem, but I doubt he will take it. And woofers are not killed by too small an amp. I've seen plenty of dead ones and none of them were killed by small amps. B&O makes high fidelity home gear, they smartly provide a myriad of protection strategies to protect the speakers from the users, but they are not nor ever will be pro audio designed for long, high volume abuse as opposed to sensible home audio use. 

The OP kind of wants his cake and to eat it too...something that rarely happens in the real world no matter how much you wish it were true.
