Four all new for 2024 DEBRA sub models, 21 to 41 inch tall, 8-10-12inch drivers, new mix'n match!

Please help us welcome our all-new baby DEBRA 20, the world's most delightful and smallest-cabinet subwoofer array!  8inch driver, 21" tall w/10" square footprint.  Less cabinet improves the S/N ratio.   

It's equally true and unintuitive that the smaller the room the more audible and detrimental are bass mode effects (bunched tighter together) and the more valuable is a subwoofer array.  Bass modes explain why serious audiophiles would never trade their smaller luxury stand-mount for any cost-no-object floor-stander, the latter exciting all forms of bass mode effects.) 

We now offer smaller-cabinet subs (21" tall w/10x10 footprint) for smaller rooms.  Even in the smallest room, mini-monitor lovers can now enjoy the best bass quality they have ever heard, exceeding the bass quality of any full range speaker in a domestic sized room.        

Generally, the smaller the main speaker, the higher is its bass cutoff.  The higher the distributed sub array crosses, the wider is the range with bass modes smoothed and the better is performance.  Non-distributed subs must cross as low as possible and always below 80 Hz.  Conversely, two sub amps driving a distributed sub array can cross up to about 100 Hz without proximity effect: there's no proximity effect even standing directly over a sub.  This unique performance feature of the array favors main speakers like stand-mounts with higher bass cutoff.             

Compared to our standard 10.5inch driver DEBRA 22 and DEBRA 32, DEBRA 21 cuts off only a few Hz higher (about 20 Hz) and has only 3 dB less maximum output. 

DEBRA 21's only potential down-side is that its labor and materials cost is so close to that of DEBRA 22.  But if you want subs easier to ship, receive, unpack, setup and site, DEBRA 21 is all that and more, providing bass to 20 Hz prior impossible to attain in smaller rooms.  Your luxury mini-monitors and our bass array is a match made in heaven.    

Mix'n Match

One sub array = four or more subs.  Sub prices listed in pairs allowing shoppers to mix equal numbers of DEBRAs 21, 22 and 32; ditto equal numbers of DEBRA 22, 32 and 41.  Do NOT mix the extremes of DEBRA 21 (the smallest, 8" driver) with DEBRA 41 (the largest, 12.5" driver.)  IOW the 10s can mix down or up but do not mix 8s with 12s.    

For 2024 DEBRA 22 with slightly different dimensions replaced original DEBRA.  DEBRA 22 measures 22" tall with 12" square footprint while the original DEBRA measured 24 tall with 10.75 x 13.5 foot-print.  Unchanged are the 10.5" driver, patented dual-flared Precision Port and Cherne air-tight sealed pipe plug.       

We have an all-new CNC cabinet vendor.  In spite of its slightly smaller cabinet volume, DEBRA 22 is heavier, more rigid and has less cabinet talk for improved S/N ratio.  DEBRA performs better and is more compact.  

Cosmetic quality improved and our new shipping carton is double-corrugated vs. the outgoing single-corrugated carton.          

Our all-new DEBRA 32 replaces the outgoing Tall Sub.  Like the Tall, DEBRA 32 has two patented dual-flared Precision Ports and a small bump (about 3.5 dB) centered around 20 Hz to benefit performance in larger than average rooms. 

Per our usual standard, all ports include an air-tight removable plug.  Plugging one port cuts the bump in half, plugging both ports provides about flat response.  This makes DEBRA 32 very flexible for future use in a smaller room where it matches DEBRA 22 performance.    

DEBRA 41 replaces the outgoing Magnum.  One DEBRA 41 has output capacity approximately equal to 2.5 regular DEBRA 22.  Cabinet quality is up as is weight and density with less cabinet talk and better S/N ratio.

Mix and match even number of DEBRA 41 with any other pair of DEBRA model except DEBRA 20 because the difference in output is so great.    

The entire line of DEBRA subs shares the same simple and elegant cabinet design.  

Our symmetrical sound room is dual use with total light control, a 4k projector and perforated retractable screen; room volume is 3300cf.  Two kilowatt sub amps > four regular DEBRA 22 subs easily play the live artillery cannon shots @ THX level on the movie Master and Commander.  Calculate your room's total volume.  To match the bass output capacity in our room: 

A room displacing 8250 cf is 2.5x larger than our room, requiring four DEBRA 41s.

A room displacing 5k cf is 1.5x larger than our room, requiring two DEBRA 22s and two DEBRA 41s.

A room displacing 1650cf is half the volume of our room, requiring only four DEBRA 21s.
