You are a hero!!! I would never touch my speakers!!! I'm afraid of damaging them!!! :bluezoned: :scareboo:

Nice. The 703 isn't that bad to take apart. I've had mine apart simply for the sake of curiosity.

The odd thing is trying to get the first of those two screws started while holding the driver.

I removed a driver on my 800's for a small repair and it was difficult. The wires are short and soldered to the driver and the driver is very heavy. It was nerve wrecking.

What happened to your original bass driver that you needed to replace it?

[scanido]

Why did you need to replace the driver?

[Race Car Driver]

I did the same thing in my N802s and for curiosity ASW855. Ill have to dig up the 802 pics.

I still find it amazing that something as simple as a raw driver can look so cool.

I dig the metal used on the motor and the basket.

I didn't find that too bad actually, but I have a track car I mess with all the time so i'm quite handy with tools!

They are pretty basic inside alright, I guess you pay for the workmanship and design etc. Dead easy to do though. I would say it's more difficult on the 800 series ones though. Also I wouldn't like to remove the midrange driver on mine, I wouldn't know where to start with that one....

[PewterTA]

The black plastic surround turns (counter clockwise I think) or maybe it just prys up (can't remember now) and it exposes the screws to remove the midrange on your speakers Lewisimo.

Incase you want to look inside. :T

I guess with a screw driver it would be pretty easy.

But, when I did mine my tools were at work and I was just screwing around with a Gerber multi-tool. ops:

Thanks fro posting!
May you volunteer how the driver was damaged?
One of my 703 bass drivers is rattling and I'll need to order a new one
Oh well - I love these to death otherwise

I am on my third set of B&W's (now 703's) I am running them with a NAD370 amp and am considering an amp upgrade.. any recommendations would be greatly appreciated (my budget is A$2,000 to $3,000) ..thanks simon k

You'll probably get more mileage by starting your own thread.

However, Rotel amps pair very well with the 703 and might be worth considering.

Thanks for posting this up! It's good to have this info in case I ever need to perform surgery on my 703's!

Sell your amp and get a NAD M3 if you like the NAD sound. You may need to look second hand to meet your budget...only you are in the US so the price is about right.

Whats your room like?. You may get better bang for the buck if you have the ability to tweek your acoustic space,

Good work Lewisimo!

thanks for advice brizvegas (BTW I live in SYD and work midweek in brizvegas..!) I would love a NAD M3 but looks like I would be up for $4 to $5k...ouch.. maybe a NAD 375 would be a cheaper alternative... I am also interesed in Rotel or Cambridge audio... I need to spend some time auditioing to sort it out...anyway, any advise or comments is appreciated..thanks simon
