GLOW Sub One Powered Subwoofer with Passive Radiator

Sale price1 Price2 Regular price4 5

We have sold out of our final production run of the GLOW Audio Sub One.

 At 10 inches square, many audiophiles consider this the best small powered sub available from any source. We will update you on progress in the development of our new and improved Sub One (Series II).

While the design of award winning, no nonsense tube amplifiers remains our primary focus, we continue research and development of new speakers and subs that match well with our renowned tube amplifiers.


Our loudspeakers sound great as is, but if you want to experience the feeling that only a deep bass response can provide, you might consider using our small speakers with our perfectly matched GLOW Sub One powered subwoofer.

"..serious weaponry..."

The GLOW Sub One is a 2009 recipient of a 6 REALSIZATION AWARD, for providing outstanding performance and extreme value. See excerpts from the review below:


"Glow Audio's Sub One is beautifully built and superbly attractive in its anthracite/bamboo skins and classy brass footers. It performs exactly like a musical subwoofer should even in a big room - quick, properly damped, powerful, without bloat, ring or sloppiness and good into the low 30s."

"Make no mistake, the Glow subwoofer is the real deal ... the doubled-up drivers of the Sub One have more kick and energize more profoundly ... you can play the most beastly bass whoppers in your collection and not feel shortchanged. That it manages to do all that for $408 delivered globally is shocking. It truly is. Bravo. "

"Agile, tuneful and substantive."


July 2009


Some of you may not require deep bass response (for example in a small room or office) and would consider our smooth sounding small speakers all you need. But if you do want to feel the bass,then we recommend use of the GLOW Sub One, now available for worldwide delivery. Approximately 9" square,our sub is definitely an over-achiever.

Utilizes a 6.5" woofer and a downward firing passive radiator to provide deep and accurate bass response without the "thud" characteristic of small ported subwoofer enclosures.

The GLOW Sub One is an attractive and stylish component, with gently curved natural bamboo siding and an attractive metal grill. You may not want to hide it behind your sofa after all!
