Getting to know 3-way speaker and it’s benefits

When shopping for speakers online, you may have come across the term 3-way design. What are they and how do they differ from conventional speakers? Here, we take a closer look at 3-way speakers and the advantages they offer in home theatre systems.

A three-way audio speaker produces sound from three separate drivers or transducers. The three speakers i.e the woofer, mid-range and tweeter are optimized to deliver the greatest efficiency in their respective range of frequencies. In technical specifications or drawings, they may be denoted as LF (low frequency), MF (mid frequency), and HF (high frequency).

As the speaker drivers are optimized to work in a set frequency range, together they deliver clearer, more accurate sound along with reduced amplification requirements. To put things in perspective, most portable Bluetooth speakers usually have a coaxial or a full-range driver while many bookshelf speakers are 2-way and use only two drivers i.e. a mid-bass and tweeter driver.

How are 3-way speakers designed?
To optimize the speaker’s sound, an assemblage of electronic circuits called crossovers are integrated into the design. The crossover feeds each driver with a filtered frequency range of the audio signal from the amplifier or AV receiver. The crossover circuit feeds the woofer, midrange, and tweeter driver with only the low, mid and high-frequency signals respectively. This electronic wizardry is what ultimately forms the basis for a three-way speaker. In home theatre speakers, the crossover is usually placed inside the cabinet.

In professional audio, however, rack-mounted active electronic crossovers are used to distribute the frequency in either 2-way, 3-way or even 4-way configurations. The same principle is used in bi-amping or tri-amping. However, the amplification process happens after the frequencies are segregated via a crossover.

A look at the speaker drivers
So, do the three drivers differ in size and performance? Yes, they do. Let’s have a look at what sets them apart.

Woofer or Low-Frequency Driver
The woofer is the largest driver in the speaker, usually measuring between 5 to 12 inches in diameter. It generates low-frequency sounds in the bass range, such as drums, bass guitars, explosions and thunder etc. Most woofers have a cone either made of paper or plastic, a strong permanent magnet and a wire roll known as the voice coil. The same components are are used for the other transducer as well. However, they differ is terms of size, voice coil and cone material selection. From all the three driver variants, the woofer emanates the strongest sound thereby requiring relatively high amounts of power.

Mid-Range or Mid-Frequency Driver
In comparison to LF drivers, the mid-range driver is typically smaller ranging between 6 to 8 inches in diameter. It takes up the task reproducing mid-frequencies in which sonic elements like vocals, speech, and most musical instruments are nested comfortably. When heard in isolation, it will produce a reasonable sound. However, it will lack bass punch and treble brightness. Given how important the mid-frequencies are for the listening experience, many speakers often deploy more than one mid-range driver for added power, clarity and definition.

Tweeter or HF Driver
The tweeter is the smallest driver in the speaker. It usually measures no more than a few inches across. The drivers are typically made from highly conductive metals such as aluminium, titanium, magnesium, or even copper. It operates at the treble end of the audio spectrum, producing high-frequency sounds such as hi-hats, cymbals, percussions, flutes and others. Without a tweeter, the sound emanating from a speaker will lack brightness, clarity, and deliver a dull, muted and lacklustre sound.

The takeaway
Three-way speakers are preferred by audiophiles because of the clarity, tone and efficiency they deliver. Typically, most floorstanding speakers are 3-way design. However, there are 3-way bookshelf speakers available especially from high-end, audiophile-grade brands. If budget is not a constraint, we would definitely suggest buying a 3-way speaker for your home theatre system in India.

How to use Agile & Scrum to develop software efficiently?

Life has eventually become easier and better. Appropriate software should be developed for best results. The software is a program that is run on a computer. It instructs the computer to perform specific tasks. This article will give you an insight of how to carry out the activity by the use of Agile & Scrum.

AGILE

Agile development refers to classifying procedures that are depending on their iterative growth to enhance software development. Agile development processes should be within the set Manifesto. The solutions and necessities develop if the self-organizing team collaborate with the cross functional team. The methods advocate for a management process that aid in the following;

• Frequent examination and adaptation.
• A qualified and well-supported teamwork by the leaders.
• Accountability and self-planning.
• Best engineering practices with the aim of delivering quality software.
• A business model capable of fulfilling the customers’ needs and the goals of the organization.

SCRUM

It is a set procedure that is used in the development of software. The framework involves a lightweight process that is used in development. A particular set of tasks is done as directed to have consistency with the framework. Development cycles known as Sprints are required in the context process while pair programming requires XP framework. The process involves little work. It saves a lot of time.

Specific notions and tasks such as time boxes, responsibility, and artifacts differentiate it from other procedures. Complicated software and product growth use it for management by practicing increment and iteration. Time is saved, and productivity is increased remarkably. Organizations can smoothly adjust to the ever changing demands. This creates a product that helps in accomplishing the actual business goals.

Advantages to the firm
• Deliverables increase in quality.
• Adapt well to change.
• Estimates provided are better and less time is used to create them.
• More control of the project program and state.

You must comprehend the following significant terms used for you to understand how to develop software efficiently;

1. Team.

This consists of database people, developers, product owner, support people, master, and a tester. They work together relatively and at intervals to create and apply the features.

2. Sprint.

The duration in which the work should be completed and presented for review or deployment is called Sprint. It lies between 2-4 weeks in most cases.

3. Product Owner.

The primary stakeholder of the developed application is the product owner. He or she is responsible for customer clarification. The team should be able to access the product owner whenever they need him.

4. Master.

The master coordinates the team and ensures that they produce and progress efficiently.

5. User Story.

The necessities implemented are called user story. They appear in the form of a short paragraph.

6. Epics.

The unspecified user stories reserved for the future are called Epics.

7. Product Backlog.

User stories get stored in a place called Product Backlog that is managed by the owner.

8. Sprint Backlog.

All the collected user stories that are worked on by the team at a particular sprint are known as Sprint Backlog.

9. Story Points.

Story points quantify and show the complication in the user story. The complexity gets presented as small, medium, or high.

10. Burn Down Chart.

It tracks the everyday work of the team to determine whether the progress towards completion of the user stories is achievable within a particular sprint.

11. Velocity.

The total of all story points stored by the team within a particular sprint is known as speed. It helps in judging the team’s efforts.

METHODOLOGY.

Software development is as follows:

a) Plan for a meeting
The team gathers for a meeting. The product owner chooses a user story according to priority. They size the story based on its complexity after discussing it.

b) Implementing of Sprint Tasks
The team works on the user story until it is finished.

c) Daily Meetings.
The team should meet daily for at least 15 minutes to articulate on what each member did yesterday, plans for today, and any barriers available.

d) Meeting to Review.
The team member should come together to demonstrate the applied user stories to the owner after every sprint.

e) Retrospective Meeting.
The meeting is held by the team after every sprint to brainstorm on what went on smoothly, the rough times, learned lessons, and actions to take on specific items.

CONCLUSION:

The above methodologies may be difficult for some people at the beginning. Your application will start growing if you have enough practice and sufficient resources. Allocating the team members for self-study and presenting their findings every day offers an excellent platform for knowledge and skill enhancement on this development.
