Because of the big bass lift offered by the double bass-reflex type enclosure, test tones at 40Hz, 31Hz, 25Hz and even 20Hz are quite audible. The advantage is that there is no crossover distortion or suppression of the dynamics which occurs with almost all passive crossover circuits. Those who know me know that I love my flea power single-ended SE valve amplifiers. This process worked out very well. Now some builders may opt to use a use a baffle step correction BSC network.
The power output from these amps ranges from 2. The skills required can vary from simple drilling holes to complex carpentry. There are many tweaks and modifications that can be done to improve the drivers. Two strands of wire wrap wire fine 30 AWG silver plated copper wire is use for both positive and negative of the speakers.
Fostex FE206En in Double Bass-Reflex Speaker Enclosure
The horn speakers 26en the Fostex FEEn 8″ fullrange driver. I find that the mid-range richness is why these drivers can sound good with acoustic instruments and especially vocal. The fine metal grills are held on with four rare earth button magnets and are easy to pop on and off. 206ej 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 quality DIY gear don’t tell the wife.

The whole box sounds like it is working real hard. The Fostex FEEn double bass reflex speakers sound excellent.
fostec To achieve this I used a cheap paint-roller and after going once around the box with a white undercoating paint, I went around three more times with a semi-dry roller to really tease-up that stipple finish.
That seems consistent with what is described on the enclosure plan, “Internal volume of 45 liters tuned to approximately 50Hz Fb. To evaluate I listened to the speakers with and without the BSC circuit, with and without the grill covers and all possible combinations in between.
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 foostex. The top chamber of the double bass-reflex speaker boxes is lined but not stuffed with Dacron poly fill. I have had a pair of Fostex single driver back-loaded horns for a few years now. What the BSC network does is to tame from the mid-range on up, without affect the lower bass response.
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. But if you find just the right volume the speakers can really sing.
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 fkstex sand paper before applying a coat of primer. 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 the bass lacks detail while the mid-range sounds shouty.
The bass from these speakers was always very impressive. The circuit is simple, just one inductor and one resistor in parallel with each other and in series with the speaker.
Last update 1 September Other advantages of the double bass-reflex speaker compared to a conventional bass-reflex system are a reduction of the cone excursion around F 3 and a corresponding reduction distortion. But I don’t shy from timber or metal enclosure preparation and finishing. Figure 2 shows typical values for use with this double bass-reflex speaker enclosure. Anyone who has tried a DIY audio project knows that you generally need to know more than how to just read a schematic and use a soldering iron.
Figure 1 below shows the speaker box plan from the datasheet. When it comes to carpentry I leave that to those who are better skilled than I. This was a satin finish in black. You can use the online calculator to determine the value of choke and resistor required based on the width of the speaker baffle and impedance of the speaker.
The double bass-reflex DBR speaker system is a variation of the standard bass-reflex BR enclosure that is intended to achieve further extension of the bass response. After two hours of drying time I applied the top coat to the speaker boxes. Because these speakers are so fast and dynamic it really is a challenge to find a subwoofer that can keep up.

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 back loaded horn speakers are large and according to my wife ugly speakers.
While the rise at 40Hz does not make itself present in general music listening, it does add drama when listening to movies which is the primary role these speakers are intended to fill.
Gold plated binding posts are used to connect the speakers at the back. Not quite black more of a dark charcoal. The Fostex FEEn drivers are “fullrange” types and their main appeals is that no crossover is required. The best combination turned out to be with the BSC circuit and no grills covering the drivers. For those who will ask, the impedance equalization circuit Zobel network for the Fostex FEEn driver shown Figure 3 can be used. The bottom chamber of the speakers remains empty. Experiment by starting with a speaker toe-in of about degrees and adjust for best results.
The amount of speaker toe-in will vary dependent on the listening room, amplifier and personal preference. You will want to take time to find the best sepaker placement as proper placement will be rewarded with excellent acoustics.
