        Productomschrijving

        The TEBM46C20N-4B 3" full-range from Tectonic offers extremely flat response from 200 to 20,000 Hz. It is an ideal driver for compact audio applications that require a full-range, high performance acoustic solution.

         

        Highlights

        • Bending-wave technology and pistonic modes of operation improve high frequency response
        • Flat diaphragm increases dispersion for better off axis response
        • Less than 1.375" deep for mounting in extremely shallow locations
        • 67" across for close center-to-center spacing in line arrays

         

        Product Details

        Tectonic TEBM46C20N-4B BMR 3" Full-Range Speaker 4 Ohm

         

        The Tectonic TEBM46C20N-4B 3" full-range speaker achieves the maximum amount of quality sound from small enclosure sizes. Aside from the benefits to acoustic engineers, the BMR's compact, square form factor also appeals to designers. BMR drive units can be a cosmetic feature of a product, or be integrated discreetly into designs—and potentially even hidden from view altogether. The technology's wide directivity enables flexible placement options, while the wide frequency response means BMR drivers can also deliver cost savings to engineers, since no crossover components or frequency-specific drivers are required. The TEBM46C20N-4B 3" drive unit has an extended frequency response with wide directivity and is ideally suited to compact full-range applications that require a high-performance acoustic solution. Typical application examples include mp3 players, docking stations, and Internet/DAB (Digital Audio Broadcasting) radios, and home theater speaker bars.

        The only problem with this driver is the Xover point. No matter how hard you try (and you shouldn't really), it won't play low - lowest crossover point you can use is around 100Hz, which makes it pretty difficult using a passive crossover. I have these drivers in two applications already. I replaced tweeters in my car with these BMRs and boy... The difference is MASSIVE. Not only are these things able to cover much wider spectrum than dome tweeters, they are also much better at crazy off-axis angles - Tectonic claims they work over the entire frontal hemisphere and they really do. It required two additional amp channels though, with an active crossover (at around 200Hz). Having the entire midrange play from the same point as high frequencies is totally worth it, though. The other application is in satellite speakers connected to my PC, combined with miniDSP. Unfortunately here they uncover pretty low SNR of miniDSP and the inability of playing at least from 80Hz becomes a bit of a problem. 100Hz is a bit too much for a subwoofer even with 48dB/oct crossover. They would be great for an active 2-way, however I do need the speakers to be small, so in my case it's not an option. This is a perfect driver for active 2-way speakers. I wouldn't combine it with additional tweeter, as it goes against the philosophy of BMR and what it's made for. It doesn't even need a tweeter. It's very linear in the entire audible spectrum above 150Hz and off-axis response beats pretty much any dome tweeter.
