Another vote for some form of protective cover Mark. Although being permanently broke, my vote doesn't exactly count for much. Nevertheless, I suspect it'd be an option worth having. IIRC, you can create polls on the forum, so perhaps one could be set up for this. Quick & easy way to establish over the course of, say, a month, what the consensus if any would be.

Would you have any images of the protective cover you had designed?

Remember to be gentle when touching the cap with the nossle.


Neo: Hope we can get together for the shows in Singapore! I'm gradully getting my strength back and providing I get an "all clear" (no returning cancer) from medical tests this July, I should be OK to work outside HK/South China.
Hi Mark,

I am glad you are turning better. Hope to see you in Singapore.

Will try out your vacuum cleaner method.

And YES from me for the protector grill.

Hi Mark,
I'd be down for probably several pairs for CHR70, one pair for A7s, one pair for A10.2 and possibly a pair for A12P (if I ever get around to building the A12P Pencil)......would love to see these covers offered!

Put me down for 8 covers for the A7.3. With magnets, covering and uncovering the drivers is quick and easy, and would give me peace of mind.... Would love to see them brought back..

Hi Mark,

Personally, I would prefer a protector that we can still play the speakers when it is installed and take it off for serious listening when the house is quiet. For such an option, you could count me. If the speaker has to be off with the protection, not much interest since the drivers play almost all day for radio, tv, etc.

While clearly not capable of the same degree of physical protection as mesh / perfed metal, a fabric grill on light (1/4") MDF frame can certainly conceal the drivers from the inquisitive. Out of sight, etc..

I hate building a pair of finished speakers without them - flush mounted neo bar magnets in the cabinet face and grille frame make for a quick and auto-aligning attachment. Just don't use the grilles as handholds.

Some of us have taken advantage of the sale to snag enough for HT use including dual driver L/R.

With the new modular architecture which I think we'll first see in the A8, could a light mesh grille be incorporated into optional extra bezel ring?

I certainly agree that with very low production volume drivers such as the MAOPs, one can't be too careful. I won't reveal the landed cost on my 7s, but suffice to say that with airfreight, duty, brokerage and "consumption taxes" it was more than 3 times the going retail for Alpair7.3 .

BTW, if not already mentioned, note that Madisound is currently clearing remaining stock of A7.3 ( ie. minus the drive train arrestors) for $65 ea - their site's not clear on inventory level, but they might not last long at that price.
I was so much older then, I'm younger than that now.
