OUR PART # RC-1209
Recone kit for LS-1209 woofer, used in Turbosound model TFL-760H
The TFL-760H 3-way medium dispersion mid/high loudspeaker enclosure achieves outstanding transient ability over twice the nominal horizontal coverage angle of a Flashlight® enclosure, thus giving rise to its name: Floodlight®.
The use of specialised cone-type transducers, in combination with unique Axehead™ technology, results in high efficiency, accuracy, very low levels of distortion, even dispersion and exceptional intelligibility, enabling it to be considered for a multitude of near and mid field applications. Floodlight is therefore available in various housings and flying configurations to meet the specific requirements of a large range of applications.
The TFL-760H is the fully equipped touring version featuring an access door with integral multi-way speaker cable, heavy duty wheels, flush handles, birch plywood construction and optimised truck-pack dimensions. The dimensions and positions of the keyhole fly plates allow use of the highly advanced and well proven Flashlight flying system. All of these features combine to give a system unsurpassed in simplicity, ease and speed of handling, and long term durability.
The loudspeaker complement of the cabinet consists of a very powerful low/mid 12” cone loudspeaker which, combined with the Axehead™ waveguide, handles frequencies between 180Hz and 1.3kHz. The high/mid band between 1.3kHz and 8kHz is covered by a similar combination based on a specialised 6.5” loudspeaker. The remaining high frequency band, 8kHz to in excess of 20kHz, is handled by a 1” VHF compression driver. Perfect time alignment is achieved by the careful positioning of these three components and their wave guides within the enclosure.
The TFL-760H can also be used to augment Flashlight systems where venue dimensions dictate wider coverage and shorter throw.

Remove the old cone and coil assembly from the basket. As soon as the coil is removed from the magnet it is recommended that pieces of masking tape are used to cover the gap to prevent foreign material entering during the cleaning process. The gap should be covered if the unit is left standing without a cone fitted for long periods of time.
Remove all traces of old adhesive from suspensions and surround lands then clean using a good adhesive solvent.
When all surfaces are clean and dry, place the four spacer cards upright and evenly spaced in the magnet gap around the pole piece.
Apply a small even bead of solvent based adhesive to the bottom suspension land and also to the chassis top surround land at a distance of approximately 2mm from the inside edge.
Place the cone assembly over the spacer cards, ensuring that the cards are on the inside of the coil and the solder tails are aligned with the speaker terminals.
Press down the assembly with even pressure until the suspension contacts with the bead of adhesive on the suspension land. At this stage the adhesive should be starting to cure yet soft enough to penetrate the suspension fabric. Apply even pressure to the suspension joint and the top surround joint so that the adhesive is evenly distributed.
To make sure that the cone assembly is properly aligned visually check that the surround is flat, and also check that no one spacer card is held tighter in the gap than the others. Continue to apply pressure to the adhesive contact points for a couple of minutes until a good even bond is achieved.
Solder the braids to the speaker terminals but ensuring that the leads cannot come in contact will the suspension or the cone. Trim the tails as near to the solder joint as
There are two types of dust cap that are used on standard speaker types. The first has a lip around the circumference edge for you to apply a bead of glue then stick to the cone face.
The other will not have the lip so you need to place the dust cap on the cone and apply a bead of glue between the dust cap edge and cone body. Place a weight to the cap and
leave to dry for at least 1 hour.
The unit should be tested with a continuous sine wave across the operation frequency range. Under no circumstances should frequencies below 100Hz be applied to a midrange unit . Start by using a low level signal and gradually increase the level checking for buzzes or ticking, but ensure that the unit is only driven at high power within it’s operating frequency range.
