New Markaudio Drivers

Im more into far field listening on a recliner 😊

Im thinking of ways were i can avoid woodwork. Thats how this lxminis came to my mind.

But now its clear for baffle less none of the FR drivers can do that

Neither can anything else in the dynamic driver world for that matter. Not without major EQ. That's the problem with the laws of physics -they have a nasty habit of getting in the way.

I hear you. Thanks for clarification. 🙂

The thing that attracted me to lxminis are the simplicity.
My design aims were that all frequencies above 80hz should be from single driver. But now its clear for baffle less none of the FR drivers can do that

As the LX mini is a system that relies on custom EQ - either via proprietary miniDSP or the Nelson Pass analog crossover/EQ -four channels of amplification, and specific drivers, I’m not so sure I’d use “simplicity” as a descriptor.

Was this a basket issue with the alpair6s or just bad luck. A pair of a6,s we purchased a few years ago but never used seem to have fractures in the 3 legs of the basket. The haven't completely separated but may compromise the integrity of the driver.

Yikes! How did that happen?
Did it suffer a fall, or did the cracks just appear suddenly?

 

[paul burchell]

They have been in the box since new stored in the closet.

 

[planet10]

I have never seen that. epoxy time.

[paul burchell]

That's what I was thinking Dave.

 

[Scottmoose]

Not something I've seen before either, so I suspect bad luck I'm afraid. Some epoxy should sort it though.

 

[paul burchell]

After a close look at the second driver there seems to be similar fractures in one of the 3 piece legs.

J B Weld is an epoxy brand favored by many. They have "5 minute" and "24 hour" formulas. The 24 hour version is quite strong but the 5 minute version would probably do OK here.

Hopefully, none of the suspension is affected by this. I would guess damage during shipping? We used to do "shock and vibe" testing; some of which was to simulate shipping handling and damage. Knowing many of my buddies that worked for UPS, FedEx and other shippers; if it said fragile; they threw the boxes even harder!

 

[paul burchell]

I hear ya about the shipping and I do have jb weld around, I recently used it to re-attach a dust cap that dropped off. They came in a case of 24 and were the only pair of 6s in the box.

There's even a picture for the illiterate monkeys.

That is what i use.

At the factory this is called 2-pack glue.

I'am about to build a WAW with P7HD + A12PW with XO between 250 hz and 350 hz
Before I make my Madisound order, somebody know something about the performance of new Driver CHR-120 vs A12PW considering it cost 33% less and share the same basket and bass oriented?

 

[planet10]

An interesting thot.

Sims show CHR-120 will reach about a hz lower in 40 litre (vrs 35 for the A12pw), and has a bit more swept volume. About a dB more sensitive. Metal cone might make for a better blend than A12pw’s paper.

On the other hand, Alpairs are usually more finessed, CHN are in the cheap metal baskets and CHR are the low end line. But you are only using it for bass.

CHN-110 goes as low as A12pw in the same volume, not quite as much swept volume.

And $66/90/$135.

You could buy 2 CHN-110 for less than an A12pw. That wins the swept volume race :^)

[audiomovil]

Excellent!
What happen if I use the A12PW Nanotyrannus MLTL and XO for the CHR-120?

 

[planet10]

You’d need a slighly different TL and teh XO would likely change as well.

[audiomovil]

it seems my best bet is to stay with the alpairs.
