MrRCSound Bass Transducer Speaker (Speaker) for Aircraft - MRS015

There is not need to cut holes on your plane to mount the bass transducer. Simply peel the backing off the self stick adhesive and stick the speaker onto the wall of the inside of your plane. This turns your whole plane into a speaker - really. You can increase the decibel level of your single bass transducer by using an additional TT-25 transducer. A second TT-25 easily plugs into the sound board. A second TT-25 is recommend for planes 1400mm to 1650mm. If your plane is over 1650mm, we recommend a 3 additional TT-25 which also requires the MrRCSound amplifier. You can keep TT-25 in each of your planes and move the sound board from plane to plane. This way you have sound in every plane!


Supplement the TT-25 transducers to increase the bass tones. Recommendations are to use in conjunction with one or more TT-25, not to be used alone. This transducer focuses on the lower tones so it must be used with at least one TT-25. The net effect is an overall increase in bass tones, while still maintaining the nuances of the sound.


1m tests show nearly identical output to the TT-25, but may sound slightly less because of the lower tones. 50' test show a slight 1-3db drop in overall volume over the TT-25, but the overall tone is lower.

Speakers are rated in SPL, or Sound Pressure Level. The higher the SPL of a speaker, the more efficient it is. Meaning it can put out a higher sound level, with less energy input. Most speakers in the 2"-4" inch size range are rated about 84-86db SPL, or decibels produced at 1 meter with 1W of input. The Bass Transducer is rated at a higher SPL. This means it delivers as much or more sound output than most 4" speakers in a smaller and lighter package (only 2.5oz) while using less energy at that same time. This translates to more flying time!
