The circuit is simple, just one inductor and one resistor in parallel with each other and in series with the speaker. What the BSC network does is to tame from the mid-range on up, without affect the lower fosttex response.
Fostex FEEn in Double Bass-Reflex Speaker Enclosure
Not quite black more of a dark charcoal. Because these speakers are so fast and dynamic it really is a challenge to find a subwoofer that can keep up.
You will want to take time to find the best sepaker placement as proper placement will be rewarded with excellent acoustics.
Luckily when the double bass-reflex speaker boxes arrived they had already been sanded down and that meant I only had to finish the surface preparation with a pass of fine sand paper before applying a coat of primer. The bottom chamber of the speakers remains empty. The skills required can vary from simple drilling holes to complex carpentry.
The horn speakers use the Fostex FEEn 8″ fullrange driver. But when it comes to flea power amps they can make “boogie” real loud. You can also try to wall-load the speakers but pulling them closer to the rear wall to try lift the low-end. The Fostex FEEn drivers are “fullrange” types and their main appeals is that no crossover is required. The double bass-reflex speaker enclosure plan is from the datasheet that was included with the Fostex FEEn driver.
With so little available power it is easy to understand why high-sensitivity loudspeakers are required. I don’t have a microphone setup but using the Stereophile test CD, bass starts to roll off very slowly from about hz until you reach about 50Hz where there is a definite rise and a there is an even bigger rise at 40Hz.
The extremely large magnet of the driver is also covered with bitumanized heavy aluminium foil to reduce sound reflections from the back of the box. After two hours of drying time I applied the top coat to the speaker boxes.

Not only do these speakers round-out the 2 channel TV end of the house but it also gives me an excellent third music listening area with fkstex DIY gear don’t tell the wife. The stipple finish, which had started with the undercoat, was now built on with the top coat. The power output from these amps ranges from 2.
Gold plated binding posts are used to connect the speakers at the back. The fill material is used to 206e the rear wave from the driver and minimize standing waves and reflections within the speaker enclosure.
That seems consistent with what is described on the enclosure plan, “Internal volume of 45 liters tuned to approximately 50Hz Fb. This process worked out very well. So much so that I had to have a pair for myself.
Now some builders may opt to use a use a baffle step correction BSC network.
In the final assembly steps, most of the slack from the connecting wire double strains of lightly twisted wire wrap wire was removed and the drive screwed securely onto the boxes with supplied gasket. This was a satin finish in black.
Because of the big bass lift offered by the double bass-reflex type enclosure, costex tones at 40Hz, 31Hz, 25Hz and even 20Hz are quite audible. You can use the online calculator to determine the gostex of choke and resistor required based on the width of the speaker baffle and impedance of the speaker. A family friend had built me the back-loaded horn speaker cabinets and at the same time a pair double bass-reflex boxes also for the Fostex FEEn driver.
I have added bituminous aluminium foil to dampen the fosstex frame. See the Fostex FEEn in dual chamber box double bass reflex thread for more information or to ask any questions. Play the volume too softy and the speakers can sound quite plain and flat – play them too loudly and they start to sound compressed and fostrx bass lacks detail while the mid-range sounds shouty.
Two strands of wire wrap wire fine 30 AWG silver plated copper wire is use for both positive and negative of the speakers. Figure 1 below shows the speaker box plan from the datasheet. Now I’m triply happy.
Figure 2 shows typical values for use with this double bass-reflex speaker enclosure. The augmentation to the bass output is achieved by the use an additional chamber in the bass-reflex process.
The bass from these speakers was always very impressive. The top chamber of the double bass-reflex speaker 206een is lined but not stuffed with Dacron poly fill.
I find that the mid-range richness is why these drivers can sound good with acoustic instruments and especially vocal.
