Hello people. 

I trust you are enjoying your weekend.

I picked up a pair of RL 7000's in showroom condition with stands off an old chap who has had them sitting in his garage covered & unused for years.  His bossy wife wanted them OUT - too big apparently (ol' bossy britches running the household).

On this website the specs are as follows regarding power -

RMS power handling capacity 140 W
Music power handling capacity 200 W

The BIG question is as follows -

Can I run these with an amplifier that is 200 watts a channel (@8 ohms - Cambridge Audio Azur 840W).

I am worried that I will fry them, but then again, if you do not put enough power or quality amplification through these types passive speakers, they sound very ordinary.

I had a set of RL 6000's that I sold a while ago, and my beocenter 9500 was not powerful enough to run them / make them sing - even at low volumes, in my opinion.  The specs say 80 watts per channel for the 9500.  When I have used the 9500 with passives, it seemed more like 30).

I hooked the RL 6000's up to a Musical Fidelity amplifier (100watt per channel) and they sounded like a totally different speaker.  Quite brilliant in fact.  I would say comparable to all the powered speakers I have had (excluding the lab 3's which have an extremely crisp top end). 

This may be a debatable topic indeed!!  Grrrrrrrrrrrr!!! 

So I was thinking these big 90's beasts may be the same - needing decent power to make them sound great.  I was thinking about using a BS 3000 as a pre amp / CD player and hiding the big power amp out of view.

I haven't bought the Cambridge Audio amp yet, it is on auction on ebay now.  I have used their amplifiers in the past and was impressed by quality for the price.

Any advice would be much appreciated if you have had any experience with these speakers or have heard of anything relevant.

Many thanks in advance!!  Danke!!

G'day Rex,

How are things.

Some years ago I used my Beocenter 9000 as the pre amp for a Quad 405 (100wpc DIN into any load was the advertising blurb!)) to power my RL140 (same as RL7000) and the sound was incredible.

If I had the space I would go back to this system!

Go For It!!!

Regards Graham

I am well thanks Graham. Hope you have been as well. 

Good to hear that it was a great set up! Do you think the amp is too much though?

The BV 7000s are much more efficient than the BV 6000s - using your comparison, the BC 9500 would seemingly have 100W +

As long as the speakers don't sound "forced / stressed" you won't damage them - use common sense when choosing the volume Big Smile

Not if you are sensible!

That's what I am worried about!  I have had friends here before, and after a few bottles of vino I have had a beolab 8000 blown, and $800 worth of damage done to some Amphion floor standers.  Argh!!  Have to be more careful in the future.  I guess it's best to have a little power in reserve.

Hi Marc, I sold them, great speaker, but too big for the room I was using them in. 

 

They would look great in an open space like a converted warehouse etc.
