STAX SR-009S (new flagship)

Multilayer fixed electrode MLER (Multi-Layer-Elect-Rords) established with SR-009 has evolved to MLER 2. The finish and etching process that smoothes the edge of the electrode opening reduces air resistance and further improves sound permeability. Also, the electrodes themselves are gold plated with high specific gravity to minimize the resonance of the ultra-thin electrode. At the same time, due to the effect of reducing the electric resistance of the electrode itself by gold plating, we have opened up a new ground for high speed, clarity, silky details, and powerful texture.

SR-009S adopts a diaphragm made of ultra-thin super engineering plastic film. The light mass has realized a high transient characteristic throughout the entire audio spectrum.

The main body was redesigned to further reduce resonance as to provide a consistent sound.

ENCLOSURE:
Aluminum is a metal good for sound and suitable material for audio equipment. It is abundantly used, e.g. at the frame supporting the appearance and sound element, to realize high-quality sound, rigidity and lightweight. Almost every part of the SR-009 is manufactured through precise machine processing.

CABLE:
The high-purity copper developed from the necessity of wiring large-scale integration circuits is also known as high-quality audio cables. High-purity copper wire of 99.9999% (6Nines) purity adopted for the cable is further silver-coated and finished with the most suitable structure to drive the earspeaker.

EARPAD:
The earpad of a new design is carefully made by a craftsman's hand and features both the real leather with good humidity environment and the cushion material with moderate elasticity.

The new earpad enables hours of comfortable listening to music.

ARC (head band):
The arc is equipped with a position adjustment mechanism of 10-step slider and corresponds to the wide range of cranial form with individual difference.

NICE for soups!
Style: 34 Ounces, Size: 34 Count
We try to keep these in the house. They are REALLY nicely sized and work great for soups. They are AWESOME for soups and the only disposable plates I feel comfy using for large stews and such. Makes cleaning easy because I don't HAVE TO CLEAN! They are a bit more expensive than otherd disposable plates, but they are worth it. Pretty heavy duty plates that are thick and great for heavier foods. <3

Favorite compostable plates ever!
Style: 34 Ounces, Size: 34 Count, Style: 34 Ounces, Size: 34 Count
I’ve been using the Dixie Ultra Extra Large Compostable Paper Bowls, and I can honestly say I absolutely love them! They’re sturdy, deep, and hold generous portions, perfect for everything from hearty soups and pasta to big salads or even snacks for movie night. Unlike other paper bowls, they don’t get soggy or collapse, even with hot or liquid-heavy foods. Another huge plus for me is that they’re compostable, so I can enjoy the convenience of disposables without the guilt. They’re strong, reliable, and environmentally friendly, which is a rare combo! If you’re looking for durable, eco-conscious paper bowls that can handle anything you throw in them, these are a must-have. Highly recommend!

No more washing pozole/menudo bowls for me
Style: 34 Ounces, Size: 34 Count
Very sturdy for a paper plate. Used these for pozole at a party and saved me the hassle of washing plates. Good size, bigger than you think. When serving it does get hot so use something underneath so you don’t get burned.

Extra large paper bowls are sturdy, affordable, and make clean up a breeze.
Style: 34 Ounces, Size: 34 Count
I like the convenience of paper plates and these large 34 oz. bowls are perfect for microwave cooking. They are deep enough to handle soup, pasta, stuffing and vegetable sides with no problems and without any leaking, and are a good value for the price. They look stylish and make clean up less of a chore. You can't go wrong with Dixie paper products. They're sturdy, fun, and last through the meal.
