Model: ADKO8D2

Adire Audio introduces the Koda subwoofers, bringing XBL2 technology to the masses. The Koda series of subwoofers offer unparalleled displacement for the dollar, using XBL2 motor technology. This allows for a much more linear Bl field throughout the cone travel which results in lower distortion and higher excursion. 
 

Key Features
  • XBL2 technology for increased excursion and lower distortion
  • Y35 grade magnets for better efficiency
  • Progressive roll spiders for better linearity in all enclosure types
  • Non-pressed cone for added stiffness and lighter weight
  • Carbon fiber dust cap for rugged appearance and added stiffness
  • 15mm Xmax and 250 watt power handling for excellent output capability for the price

Overview

Adire Audio ADKO8D2 Koda 8" Subwoofer

Adire Audio ADKO8D2 Koda 8" XBL2 Subwoofer

Unmatched linearity and low distortion and at unbelievable price

The Koda series is back and better than ever for 2023! Adire Audio spent a great deal of time in the design of experiments to further develop our XBL2 enabled woofers bringing what we have learned along the way into our entire flagship XBL2 lineup. 

 After countless hours and prototypes we have successfully updated the Koda series which now includes a 250 watt RMS power rating, an in-gap aluminum inductance ring, 2” flat wire copper voice coils, progressive roll spiders and stitched tinsel leads to prevent mechanical noise.

The 2023 Koda features 8awg push pin terminals for easy wiring, non pressed kraft pulp hybrid fiber blend cone body, a multi-layer foam surround and carbon fiber dust cap that keeps the 2023 Koda as rugged as possible for your musical enjoyment for many years to come. 

 The addition of the in gap aluminum inductance ring allows the all new 2023 Koda series to dig deep and extend cleaner up into the upper end of the spectrum while not sacrificing any bottom end output. 

The utilization of high the grade Y35 magnet keeps motor strength strong and still keeps the 2023 Koda tonally balanced throughout the sonic realm. 

The utilization of high the grade Y35 magnet keeps motor strength strong and still keeps the 2023 Koda tonally balanced throughout the sonic realm. The 2023 Koda is definitely an excellent entry for the aspiring audiophile who’s looking to have solid clean output without breaking the bank!
