Leak Sandwich 150 Loudspeakers

The Leak Sandwich 150 and 250 are the pinnacle of innovation that commenced in 1961 with the original Leak Sandwich.

Those technological advancements are implemented with the utmost regard for tradition, as well as the continual aspiration to forge sound reproduction equipment of the highest quality, accessible to every discerning audiophile.

A major loudspeaker invention

Throughout the history of broadcasting and recording, certain exceptional developments have become milstones in the progress of sound reproduction.

One such milestone was the world’s very first low distortion amplifier – the famous original Leak Point One, in 1945.

Another was the pioneering major breakthrough with the invention of the fantastically rigid Leak sandwich cone diaphragm – which was demonstrably of great strength and many times stiffer than all conventional forms of cone, of its time.


To understand the impact of this innovation, one must remember that to obtain low distortion, the movement of a loudspeaker diaphragm, or cone, should follow as accurately as possible the waveform of the signals applied to its voice coil.

The ability of the current to follow these impulses accurately depends upon the lightness and stiffness of the cone assembly.

Many conventional cones: paper, impregnated fabric, plastics, aluminium etc all generally suffer from low stiffness.

This results in significantly larger areas of the cone vibrating in motion, uncontrolled by the voice coil.

These uncontrolled emotions produce transit “hangover”, amplitude distortion (peaks and troughs in the frequency response) and intermodulation distortion (lack of clarity of spurious tones).

Those shortcomings are inherent in almost all direct radiator loudspeaker systems using conventional cones, irrespective of cost.

Axial pressure response of Sandwich 150 Loudspeaker


All of these shortcomings are overcome by the Leak Sandwich construction.

Originally presented in 1961, the Sandwich used engineering and design principles applied to airframe construction.

Now, reintroduced and re-engineered with modern-day learnings, the new Leak Sandwich cone comprises of a stiff aluminium skin for the outer surfaces (where the stresses are greatest) bonded to a thick core of a polymethacrylimide (PMI) based structural foam, often used aerospace and the automotive industries.

This applied, precision-engineered use of the most suitable materials in optimum proportions and dispositions gives immense rigidity.

This means the Leak Sandwich cone reproduces the signal applied to the voice coil, totally free from mechanical break-up and its associated distortions. The result is a remarkably smooth frequency response, free from violent peaks or troughs over a very broad frequency range, indicative of an excellent, transient response.


It is not often sufficiently realised how profound the influence of the loudspeaker housing (the cabinet) is on the overall acoustic performance.

Its design requires a great degree of electroacoustic knowledge as a design of the motor units themselves.

The new Leak Sandwich cabinet benefits from 60 years of technological development since the original.

The structure consists of a composition of MDF and composite board, thus creating a second ‘sandwich’ reference, with the boards layered for optimum cabinet strength.

While the new cabinet fuses intelligent bracing with this ‘sandwich’ of materials, it also maintains a specific front-rear bracing, with the distinct, visible countersunk screw on the rear – a famous trait of the original.



With the Leak Sandwich 150 and 250, the high-frequency driver has been developed, incorporating a rear chamber damped to absorb the output from the back of the dome.

This innovation not only isolates the HF unit from the rest of the loudspeaker, it has the added benefit of reducing the resonant frequency of the treble unit.

Taking the resonant frequency below the crossover region means the audible spectrum of the bass, mid and high frequencies can be sewn together with an added dimension of detail and harmonics, eliminating the requirement to harshly adjust the definition of the high-frequencies.

And that very sewing is conducted by a crossover of the highest order, developed over thousands of hours of listening, not just simulation as is the tendency in modern loudspeaker design.



The Leak Sandwich 150 comes in the format of a 2-way standmount loudspeaker with a combination of 6.5” (170mm) low-frequency ‘Sandwich’ driver and a 1.2” (30mm) coated textile dome high-frequency driver.

Nice Suit - Light Gray Color OF Suit IS Not A Solid Light Gray, It Has Linear Designs
Size: 12, Color: Light Grey, Size: 12, Color: Light Grey
I had purchased this polyester and linen blend suit for my son, in size 12Y for him in the color light gray. The color of the suit depicted in the advertisement arrived to be a bit different upon arrival. It's not a solid color light gray, it actually has small black liner lines dispersed all over the suit. The coat features a single button in the center, and there are two side pockets fairly decent sized. Unfortunately right above the pockets are red colored lineal horizontal lines. I don't think those lines are part of the coat's design, there definitely is some printing malfunction. It is hard to see in the pictures advertised, you can see it in the pictures and video I have posted clearly. The material of the suit is fairly acceptable, actually better than expected. The child can actually wear it multiple times for various occasions. The suit emits grace along with acceptable stitching in every apparel along with the bowtie. The suit did arrive in a slide bag all folded up, so there were a number of wrinkles especially on the coat, its as if it had lost its shape. I will definitely need to steam iron it before it will be worn. Just like the coat has pockets the tailored pants also have two side pockets, and belt loops in case need of belt if the pants are loose. I'm actually glad I had ordered two sizes up because compared to his current measurements the suit is big on, especially the pants waist and length. I had measured the suit myself and below are the measurements. Pants Waist - 15.25 Inches Pants Length - 35.75 Inches Pant's Inseam 25 Inches Coat's Length - 24.5 Inches Coat's Shoulders - About 14.5 Inches Coat's Sleeve Length - 22 Inches Coat's Chest - 15.5 Inches In addition to the suit, I also received a solid colored light gray, bowtie. The bowtie has an adjustable strap, so you can set the bowtie to your comfort in the collar. You can wear it along the suit or without it if needed to match with something and still manage to look a show topper!. The coat has nice shoulder padding therefore it sits across the shoulders nicely having it hold its shape and style. Overall it's not a bad purchase, suits like these always come in handy for a unexpected or expected events. I'm glad I had purchased this suit I'm sure it'll come to use one day.

GQ KIDS...For the love of being FLY!
Size: 8, Color: Sky Blue
I am highly suggesting this suit for purchase because the color alone is a standout and will have people asking where did you get the suit from? The length of the bowtie is adjustable, the color is bright and lively, the fabric is pure quality. You can run a hot iron over it or a steamer to get the fold lines out of it from how it was packaged, but it seems that even if you just hung it up in the bathroom while running a hot shower, the wrinkling would drop. I think the purchase price is good for all that you get which is a quality blazer, great slacks and a bowtie. It's a one stop shop for a graduation event, dinner, a formal party or even a photoshoot. My nephew wears a size 7 or 6-8, so I ordered a size 8 to be safe and it fits nicely.

Cute sky blue linen suit for toddler!
Size: 3, Color: Sky Blue, Size: 3, Color: Sky Blue
I got this Trasign Kids Linen Suit in sky blue for my 2 year old, thinking my wife said “blue” (turns out she meant navy or something darker 😅). I actually really like the light, airy sky blue. It’s fresh, summery, and looks adorable on him for photos or special occasions. My wife? Not so much. She immediately said “baby blue ugly” 😅😅 On the plus side: • Soft fabric – linen blend feels gentle and breathable on little skin, no itchiness or stiffness. • Nicely packaged – arrived with very little wrinkling (barely needed steaming), which is a win for linen. • Good fit for a toddler – true to size, easy to button, and the shorts/pants have adjustable waist for growing kids. • Looks sharp once on – the set gives that classic little gentleman vibe without feeling over the top. It’s a quality piece overall, just a classic case of “what one spouse loves, the other doesn’t” on the color. If sky blue works for your family (or you’re shopping solo like me 🤣), it’s a solid buy.
