Amphion BaseTwo25 Low Frequency Extension System

Powered low-frequency extension system with two subwoofer towers and two 900 W amplifiers
MFR# BaseTwo25 system

Product Description

Modern music is increasingly bass-intensive. To pack the maximum amount of energy into the lowest octave – with no surprises in the playback – a sound engineer needs to hear and feel throughout the whole frequency spectrum. The Amphion BaseTwo25 low-frequency extension system fits equally well in any composing, mixing, or mastering setup, where correct reproduction and appreciation of the lowest octave is critical. Amphion’s innovative approach to low-frequency monitoring provides producers, sound engineers and artists with a completely new perspective on bass.

The BaseTwo25 is a state-of-the-art monitoring solution converting any Amphion two-way studio monitor into a full-range, time and phase coherent, three-way system. These full-range towers extend all the way down to 20 Hz. Each BaseTwo25 has 2 x 25 cm woofers (top) and matching 2 x 25 cm radiators (below) mounted in back to back force-canceling mode on both sides of the cabinet. The system is driven by 2 x 900 W amplifier, and controlled by Amphion’s signature filtering module with a variable-level attenuator.

In addition to providing tight, tuneful bass, BaseTwo25 improves midrange clarity and increases the midrange power-handling abilities of the paired monitors. This is achieved by gradually transferring the low-end frequencies from the monitors to the base extenders.

Features:

  • Perfectly integrated time and phase coherent, three-way system, extending all the way down to 20 Hz
  • Extremely robust 25 cm (10”) woofers with matching 25 cm passive radiators mounted in back to back force canceling mode on both sides of the cabinet
  • Driven by 2 x 900 W amplifiers housed in a 2U rack chassis and a stand-alone 1U filtering module with variable-volume control

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
