Technics SB-G90M2 Floorstanders


Kronos AV 5 Year Warranty 

Kronos AV offer a FREE 5 year warranty with all products they sell (unless otherwise stated here). If you item is faulty during this time, you simply need to contact one of our staff and they will arrange everything for you. 

How does the warranty procedure work? 

Once you have contacted us to arrange a warranty repair, we will supply you with an RMA number which will allow us to allocate the order to your account when we receive it. We will then have the manufacture repair the goods as quickly as possible and returned to you fully working. 

We will also test the goods prior to sending them back to you, to make sure they are 100% working, and you receive back a perfect product.

Do I need to keep the orignal packaging?

Yes, it is very important with all products that you keep all original packaging and boxes. This is to allow for safe shipping. Your warranty will be null and void if these are disposed off, so please keep all packaging and boxes for your purchase. 


Warranty Exclusions does not cover ordinary wear and tear by Buyer; (ii) Buyer’s non-observance of installation, operating, and/or maintenance instructions or Specifications provided by Seller in writing; (iii) Buyer’s abuse, improper use, or neglect of Goods and Services; (iv) unauthorized modifications made to Goods and Services by Buyer; or (v) any equipment or materials furnished by Buyer or any third-party (other than Seller or any subcontractor or sub-supplier of Seller).

USED ITEMS: These are excluded from this offer, and a 6 month warranty is provided on these items. 

Items which are classed as intimate e.g. cleaning products etc... are also excluded from this

What if the product comes with a warranty longer than 5 years? 

In some cases, brands may offer warranties which are longer than 5 years. In this case, they supersede our 5 year warranty, and cover you for the extended period. Again you can contact us to arrange any warranty repair, and we will take care of it for you. The manufacturers T&C's and exclusions may apply. 

Where are repairs undertaken? 

All items returned for warranty repairs are sent to our warehouse, where our team will confirm the fault, and create a detailed explanation for the engineer. This will help speed up the process, and allow the engineer to pinpoint the problem in order to rectify it in the quickest time possible.

How do I register my warranty?

Your warranty will automatically be registered upon completion of your order. All you need is to keep a record of your order number, and when you contact us simply supply our staff with this number. Our staff can then proceed with the warranty repair for you.

Unwanted vibration of the speaker units and enclosure has been thoroughly eliminated. The floor-standing speaker achieves clarity in sound imaging and fullness in spatial expression.

Point Sound Source Speaker System

One ideal in reproducing sound with full spatial expression is to ensure that the wave-fronts emitted from the speaker units are aligned at any listening position, i.e., providing a point sound source. While inheriting the linear phase concept, the SB-G90 has newly developed two-way coaxial cone units (including mid-range and tweeter) targeting high-speed reproduction with enhanced high sensitivity.

Phase Precision Driver (Coaxial 2-way Speaker Unit)

A lightweight, high-rigidity anodized aluminium dome diaphragm is used for the tweeter diaphragm. The driver reproduces a wide frequency range up to 100 kHz by using a new dome shape optimized through simulation, as well as achieving greater uniformity in phase characteristics by using a phase plug. In addition, the SB-G90 uses high-linearity-drive underhung voice coils, the magnetic gaps of which have had magnetic fluid injected to suppress temperature rise, thereby ensuring superior power linearity. These features provide reproduction of the high-frequency range with superb detail and beauty.
As with the tweeter, the mid-range also uses an anodized, lightweight, high-rigidity aluminium cone diaphragm. The magnetic circuit achieves low distortion and enhanced drive power by using large magnets, copper caps, and high-linearity-drive underhung voice coils. Also, the support structure provided by the tough die-cast frame has resonance-dispersing arms, thereby thoroughly eliminating even the slightest unnecessary resonant sound. These features enable mid-range reproduction with excellent precision and response.

In addition, the mid-range diaphragm uses a cone shape in which its sound generation centre in the axial direction is closer to the sound generation centre of the tweeter, and the position of the axial direction of the dome tweeter placed in the centre of the mid-range diaphragm is precisely adjusted, thus achieving linear phase reproduction by integrating the sound in each range without time lag. Also, the inside end of the mid-range diaphragm has a smooth shape so there is no deterioration of tweeter sound characteristics, with the diaphragm being constructed to deliver the sound emitted from the tweeter directly to the listening space. This reproduces mid-range and highs with superb precision and response, as well as excellent clarity in sound imaging.

BDMA (Balanced Driver Mounting Architecture)

With the conventional method of mounting a speaker unit to a baffle, the centre of gravity of the speaker unit was located away from the support points, and so the force acting on the voice coil when driving the speaker produced vibration of the entire speaker unit. This produced distortion in the sound waves generated from the diaphragm, resulting in deterioration of sound quality. In addition, mounting the speaker unit to the baffle is a configuration that easily transmits vibration of the speaker unit itself to the baffle, and so unnecessary vibration sound was produced from the baffle, again with deterioration of the sound quality.

With Balanced Driver Mounting Architecture, the speaker unit is mounted to a sub-baffle installed inside the cabinet at the speaker unit's centre of gravity, suppressing vibration of the speaker unit. Also, because the speaker unit is not mounted to the baffle on the front, transmission of unwanted vibration from the speaker unit to the baffle is suppressed. This makes it possible to reduce distortion in the sound waves generated from the diaphragm and reduce unwanted vibration sound from the baffle, for reproduction of a sound field with excellent sound imaging featuring impressive realism and clarity, allowing visualization of the fine details of each and every sound.

16cm Low-distortion Long-stroke Woofer

The woofers have features such as double magnets producing robust drive power, and magnetic circuits with high-linearity-drive overhung voice coils, copper rings, and aluminium short rings. This newly developed long-stroke unit achieves low-frequency reproduction with wide dynamic range as well as excellent low distortion and response even for a large excursion. Also, the support structure of the tough die-cast frame disperses resonance, thereby thoroughly eliminating even the slightest unnecessary resonant sound. And, a lightweight, high-rigidity anodized aluminium cone diaphragm is used to ensure uniformity in tone with the mid-range and high frequencies. These features reproduce robust, powerful bass.

High-quality Network Circuit

The high-precision network circuit was created through repeated listening and redesign, in order to maximize the performance of each speaker unit and achieve well-balanced sound. High-quality parts, such as a polypropylene film capacitor, an air-core choke coil, and OFC wire used for connection were carefully selected by examining their properties.

In order to prevent sound vibration emitted into the cabinet by the speaker units from affecting the network, the network is installed in its own compartment separated from the speaker units, thereby achieving reproduction of sound providing an atmospheric feel.

High-rigidity Cabinet

Cabinet strength is ensured inside the cabinet by using a cross construction with sub-baffles to which the speaker units are mounted and horizontal reinforcing panels. A separate sub-baffle is used for each speaker unit, which minimises sympathetic vibration between speaker units. In addition, differentiated use of two kinds of absorbent acoustic materials with optimal placement inside the cabinet suppresses internal standing waves and reduces incidental sound due to reflection in the cabinet.Also, multiple polyurethane (PU) coatings on the cabinet surface dampen cabinet vibration, thereby thoroughly suppressing the production of unnecessary sound. These features reproduce a vast sound field with excellent sound imaging.
