4 chanel and transparent casing

in the post above the vandal amok once again

Fortunately, there are interesting things for using the new surround sound in Windows

A transmission line loudspeaker may, for example, be transparent
A transmission line loudspeaker is a loudspeaker enclosure design which uses the topology of an acoustic transmission line within the cabinet, compared to the simpler enclosures used by sealed (closed) or ported (bass reflex) designs. Instead of reverberating in a fairly simple damped enclosure, sound from the back of the bass speaker is directed into a long (generally folded) damped pathway within the speaker enclosure, which allows far greater control and use of speaker energy and the resulting sound.https://en.wikipedia.org/wiki/Transmiss ... oudspeaker

Audiophiles don't have to limit the PC to a standard form

The transmission line loudspeaker enclosure can also be cast concrete like the Rauna Leira from the early 1980s but it is expensive and bass reflex is now offered with this brand https://rauna.squarespace.com/about-rauna

Many Japanese built their own transmission line loudspeakers, also known as back-loaded horns. In the 1970s, they were a good alternative to the offer of audio salons with quadraphonics. Four such speakers have been optimally placed in the room so that all drivers are at ear level. It still matters when playing music from stereo recordings, and in the case of 4 speakers and surround sound, it is even more important to take care of it.

Fostex now offers slim 145(W) x 343(H) x 216(D) mm TL cabinets with the 4" coaxial FE103En, which does not require a powerful amplifier. Thanks to them and traditional amplifiers from the RTV offer, you can comfortably arrange a room for playing music from 4 speakers https://www.fostexinternational.com/doc ... 0-BH.shtml

The active Tannoy speakers with bass-reflex are also very interesting. See more: British proposals for new 4-ch-surround https://audiophilepc.blogspot.com/2022/ ... round.html

The reference are active APS Coax loudspeakers with closed-box enclosures, which are produced in Poland with 6 1/2"transducers from the Norwegian company SEAS https://www.aps-company.com/coax2-en/

2x50W served as 4x100 at home

4 small active speakers do not need much power to ensure full relaxation with music in many homes

3-inch full-range driver with back-loaded horn and built-in 2x50 W amplifier, which, when bridged, will give 100 from each speaker at home and will not be a terror for the neighbors. https://www.instructables.com/Kissing-t ... Speaker-F/

The Japanese Fostex has legendary offerings with a back-loaded horn https://www.fostexinternational.com/doc ... ures.shtml
Being one of the systems where sound radiated from the back of drivers is utilized to enhance bass, including bass-reflex and double bass-reflex types, back loaded horn type enclosures make the most efficient use of such back sound. Back-loaded horn system enclosures work in such a manner that, as bass comes out of a horn mounted on the back of a driver, the rest of sound spectrum, e.g. mid- and high-frequency ranges, is radiated directly from the driver. Enclosures of this system are highly efficient by actively utilizing sound output from drivers, and respond well to the subtlest componentsof music signals.
Obrazek

The Japanese are the most active with such projects and widely present their concepts and relevant descriptionshttp://telavox.web.fc2.com/backload.html

ObrazekObrazek
The design points for backloaded horn enclosure are the cubic capacity of an air chamber, the cross-sectional area of its throat,
the horn flare rate, the horn length and the horn-opening area. Fold up the horn and crate it.

One of the things it is highly-efficient system. In other words, it has a high output sound pressure level; the backloaded horn system is an energy-efficient design. So it allows the driving by low-power amplifier, too. Low-power amplifier is good from the point of view of sensitive sound.

It plays the fine sounds because the driver diaphragm can move easily by backward opening of the speaker driver, like open back type cabinet. So, it plays the realistic sound with overwhelming high quality if its sound source is good, but that's not how it works if its sound
source is poor. Therefore, you may have trouble finding a good sound source.

You might hate the backloaded horn sound, but everyone will be surprised at the difference between the sound of backloaded horn and others. Furthermore, you will never believe the magnificent bass, the powerful sound and the instantaneous force for small-diameter driver.

Fostex offers a DIY kit with a small back-loaded horn housing https://www.fostexinternational.com/doc ... 0-BH.shtml

A loudspeaker from a 3D printer gives more possibilities

For listening to music from 4 channels, a tiny $1 bluetooth module is useless and there is no better alternative.

Obrazek

The power supply is external - plug for 220 V with transformer and appropriate electronics. This provides the amplifier with 12 V DC to drive the electro-acoustic transducer and it is not worth saving too much on VA here

Obrazek

In music stores, the cheapest Fostex offer for 4 channels at home is the PM04.c https://www.fostexinternational.com/doc ... 0.4c.shtml

Obrazek

However, these are not active speakers. This is an offer of an amplifier and a pair of traditional 2-way speakers.

Obrazek

They were active in the earlier PM04.d version, which was more expensive and is still on offer for the Japanese market https://www.fostex.jp/products/pm04d/

Obrazek

The most interesting version is no longer available. They had amplifiers operating in class AB. Basreflex opening in the front makes it easy to set up at home.

The Polish manufacturer has introduced a new solution to the market to complement active studio monitors with a coaxial electro-acoustic transducer from the Norwegian SEAS. https://www.aps-company.com/coax-2-bass-extender-en/

Obrazek
COAX 2 is first and foremost – a point sound source, full control, naturalness, precise localization of vocals and instruments. It is a reliable device for the realization of sound in the near field. Coax 2 is an extreme precision, universal tool that significantly facilitates the work of experienced sound engineers.
Audio Pro Solutions bass extender and 5 active monitors Coax create a reference set for 5.1 sound

Obrazek
The bass multichannel extender of the Coax 2 studio monitor – as the name suggests, it complements the Coax 2 active studio monitor in reproducing low frequencies. The bass from the extender is fast, dynamic, detailed, clean, transparent, and multi-channel

The manufacturer has already considered the use of active subwoofers and has to offer 10" (105 dB) and 12" (110 dB)

Obrazek

They are very powerful, but they do not have a Closed-box enclosures and and therefore are not as fast, dynamic and detailed.

6.1.7601.17514 - new surround

Post autor: BienSoundPC »

Obrazek

New speaker settings at home have been done for years.

Obrazek Obrazek

The first tests were already with Windows XP sv SP3 and Microsoft system driver 6.1.7601.17514 from November 19, 2010 for the sound processor built into the motherboard. There was also support for Windows Audio Session Application Programming Interface and Room Correction

Obrazek

Tests with this configuration on the laptop are still performed with a Samsung TV, which serves only as a monitor, although according to the manufacturer it has an acoustic power of 40W (left - 10W; right - 10W; Woofer - 20W)

4 center channel speakers in a Microsoft surround system

Post autor: BienSoundPC »

Obrazek

This loudspeaker can be purchased for less than PLN 300

Obrazek

IIt's a closed-enclosure speaker that's offered under $100 as center speakers for home theater amplifiers. Three of them placed vertically at the front and one horizontally at the back can create a very practical Microsof surround set. They are easy to match at home because they are small and come in different colors: white, white and black, black, walnut, wenge.

Obrazek

For this, you also need a 4-channel power amplifier and you can buy one quite cheaply, but you also need to provide it with optimal power supply, which may be a bigger challenge. It is worth remembering the basic laws of physics. A 12V power supply for an amplifier with a specific wattage requires a specific amount of amps. The advertised amp power suggests that a lot of ampears needed. In practice, less is enough, but at the same time you cannot skimp on them in the power supply. In this case, it can be estimated that 4 x 40 W. will be enough to freely drive these speakers and a 20 amp power supply will work quite well, i.e. with a declared 240 W or VA.

All in one PC and iMac

Post autor: BienSoundPC »

Obrazek

A Swedish magazine with a 70-year tradition in the field of image and sound recently tested the new iMac with a 24-inch screen. This review makes frequent references to working with sound, but these are general statements that should please Apple fans who plan to invest in new equipment. It is clearly indicated that there is an Atmos function, but active studio monitors will provide better listening. This means that this offer does not focus on the number of functions, but on their quality.

Neumann, the most famous brand of studio microphones, may be interesting here. The suite from this iconic brand in the world of music production allows you to perfectly calibrate music playback in a specific room and can be used with an all-in-one PC or iMac.

Obrazek

However, an all-in-one PC gives greater opportunities to ensure that the money invested gives optimal results with the help of software. https://audiophilepc.blogspot.com/2024/ ... -imac.html

An even more interesting alternative is a desktop PC and 4 active Tannoy monitors. https://audiophilepc.blogspot.com/2022/ ... round.html
