Copper clad pole piece for improved induction symmetry and less modulation distortion. The low Qts makes this driver useful in back loaded horn enclosure. See pdf for back loaded horn design. Double Bass-Reflex Enclosure 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. The augmentation to the bass output is achieved by the use an additional chamber in the bass-reflex process.
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. The use of an additional chamber in the speaker enclosure also reduces the likelihood of resonances. The interior chambers of the double bass-reflex speaker box is typically lined with a thick damping material and/or stuffed with loose synthetic or wool fill. The fill material is used to dampen the rear wave from the driver and minimize standing waves and reflections within the speaker enclosure. This cabinet plan is available in the pdf file.
I am been really really surprise with this driver, is the first time I use a full range driver and the result is unbelievable even considering the price of this driver, the details are so real, also this driver is able to work with very low volume, still you can appreciate low bass but also medium and high frequencies. I also built by myself the suggested back loaded horn enclosure, Fostex suggest to use a 21mm plywood, but I used a 24mm Russian birch plywood, the result is stunning, the enclosure became much stronger and bass freq are much louder and smooth. With high volume this driver come alive especially with my 30+30 watts push-pull tube amplifier, I can even ear music details unheard before, I am really happy with it and if you are looking to experience a full range driver well this is the one. Also a special mention to Madisound speaker store, this people are amazing and they do not just doing business but they put their heart and soul on it, one of the speaker come damaged for the fault of the carrier, I just report the problem and they sent a new driver without making a little single problem, very impressive and thanks again to Madisound.

Indeed even today the speaker component business still represents a significant part of Fostex’s monthly income although sales are slowly enjoying a renaissance in other territories.

Today RP technology is well known worldwide not just for speakers but also microphones and headphones, with the Fostex T20RP being one of the most famous studio monitoring headphones in the United States.
