PRODUCT OVERVIEW
The Infinity Be TA Be621 component speaker system is the recipient of the 2021 CES Innovation Award. It leverages Infinity’s decades-long expertise and uses advanced materials to deliver a near perfect audio performance. The 6-1 /2″ supreme woofer uses a carbon fiber cone to deliver incredibly accurate and tactile bass response. The beryllium tweeter brings the smoothness accuracy and extended response to your music, with a clarity unrivaled at this price point. Infinity Be TA crossovers are engineered to integrate the woofer and tweeter perfectly for an incredible stereo image and amazingly deep soundstage. Three levels of tweeter control let you dial in the sound to your car’s environment. The attractive magnetic grilles and innovative mounting rings allow for seamless, elegant installation with no visible fasteners.
Beryllium – Element 4 on the Periodic Table – is a rare earth metal renowned
for its remarkable physical properties that make it the ideal material for a
high-frequency transducer. Compared to aluminum and titanium tweeter
diaphragms, Beryllium offers 4.5 times the stiffness and three times more
damping, at only half of the weight. Beryllium tweeters are the centerpiece of
the Be TA automotive loudspeaker series.
This product has been given the Hi-Resolution certification on high-frequency
bands, capable of reproducing 40 kHz or above. This is driven by the 25mm (1
-inch) beryllium dome and a powerful neodymium motor for the ultimate in
lightweight performance. The powerful all-new tweeter and 6th-generation
ceramic-coated, cast-aluminum acoustic lens waveguide seamlessly integrate
with the directivity of the companion midrange drivers resulting unparalleled
efficiency, improved dynamic range, reduced distortion, and increased power
handling.
WHAT’S IN THE BOX
Infinity BeTA Be621 Installation
Installing the Beryllium dome tweeters
It is important to choose a mounting location and tweeter orientation high on
the door panel or A-pillar that provides optimum disbursement of the high
frequencies for excellent stereo imaging and soundstaging. Recommendations
include:
- Using your vehicle’s factory tweeter locations, if it has them and the tweeters will fit 1n those locations.
- Mounting the tweeters at the top of the door panels or A- pillars.
The system includes three options for installing the tweeters:
- Flush-mount cups
- Surface-mount cups
- Stealth-mount brackets
Flush-mounting the tweeters
Flush-mounting is ideal for installing the tweeters in an A-pillar, dash
corner, or door panel.
-
Cut a hole 1.9 Inches in diameter 1n the mounting surface.
-
Push the flush-mount into the hole as far as it will go so that the rim is flush with the mounting surface.
-
Thread the tweeter wire through the center of the mounting cup.
-
Insert the tweeter into the cup, then twist clockwise to lock it in place.
-
Thread the pressure-fit nut onto the back of the flush-mount cup. Twist clockwise to hand-tighten.
Surface-mounting the tweeters
Surface-mounting is ideal for installing the tweeters on a sail panel. dash
corner, or door panel.
- Place the surface-mount cup against the mounting location to mark the screw holes and hole to thread the tweeter wire through.
- Drill pilot holes for the screws and larger hole for the wire.
- Place the surface-mounting cup against the mounting location again and secure in place with the included screws. Thread the wire through the bottom of the mounting cup and through the larger drilled hole.
- Push the tweeter into the mounting cup and twist clockwise to lock in place.
Stealth-mounting the tweeters
The stealth-mount bracket can be used to install the tweeters in a variety
of locations, including factory tweeter locations and custom mounts that you
fabricate.
- The stealth mount can be flush-mounted, recess-mounted, surface-mounted, or mounted to the back of a mounting surface with the included screws.
- Once you have determined mounting location and method, remove tabs from the bracket that you will not use to secure it in place.
- Once the mount is in place and secured with screws or adhesive, thread the tweeter wires through the bottom of the mount.
- Push the tweeter into the cup and twist it clockwise to lock in place.
NOTE: if attaching to the back of a mounting surface, place the tweeter in the mount and lock in place before secunng the bracket to the surface.
Installing the 6.5″ woofers
The woofers are usually mounted in your vehicle’s factory woofer locations.
which are typically In the doors (front) or side panels (rear). If you choose
to mount them In a custom location. mounting them higher will raise the
soundstage, while mounting them lower In the doors will provide excellent bass
response.
To mount the woofer to the mounting location. place the driver against the
mounting surface and use the supplied screws to secure.
TIPS:
- It Is recommended to use the included insulating material between the mounting surface and the mounting nng of the woofer to absorb vibrations and help produce the cleanest sound possible.
- Use the included speed clips behind the mounting surface to provide a way to secure the screws. 1f necessary.
- Take care not to overtighten the screws. to prevent damage.
- If mounting in the door panel, make sure the magnet protrusion does not interfere with window or door latch operation.
- In a custom location. if the woofer is visible. use the included decoration nng and gille to cover the screws and protect the speaker cone.
- If mounting In a custom enclosure that you manufacture. recommend that the sealed volume of the enclosure is more than 0.7 cubic feet (>20L).
WIRING THE INFINITY BeTA Be621 SPEAKERS
All connections from the amplifier and to the speakers are made through the
included crossovers.
Accessing the terminals in the crossovers
Slide the Allen wrench into the hole in the front panel of the crossover. then
gently to pry up the cover of the crossover Remove cover.
Connecting the speakers to the crossover
- Use the Allen wrench to open the terminals by turning the setscrews counterclockwise.
- Insert the tweeter wires into the ‘OUT’ terminals marked “lWEETER”, and the woofer wires into the terminals marked ‘WOOFER”.
- Secure the connections by using the Allen wrench to tighten the setscrews by turning them clockwise.
Connecting the amplifier to the crossover:
bi-amping
The Infinity BeTA Be621 crossover lets you bi-amp the system (powering the
tweeters independently of the woofers). To bi-amp:
- Slide the “Bl-AMP’ switch to ‘on’.
-
- Connect a single amplifier output channel with speaker wire to each crossover ‘IN’ terminal (use the terminals marked”WOOFER/2 WAY’ for the woofers, and ‘lWEETER” for the tweeters
-
- Use the included Allen wrench lo tighten and secure.
NOTES:
- Use appropriately sized speaker wire; 14- or 16-gauge is recommended.
- Make sure your amplifier’s RMS pcwer rating Is suitable for the tweeters and woofers (see specifications).
- You will need to use a total of four channels of amplification from two 2-channel amplifiers or one 4-channel amplifier.
IMPORTANT: Because of the lower impedance of the drivers, do not wire In parallel or bridge amplifier channels to prevent overheating the amplifier.
Connecting the amplifier to the crossover: non-bi-amping
- Slide ‘Bl-AMP’ switch to ‘off”
- Connect a single amplifier output channel with speaker wire to the crossover ‘IN” terminal marked WOOFER/2-WAY on each of the crossovers.
NOTES:
- Use appropriately sized speaker wire; 14- or 16-gauge is recommended.
- Make sure your amplifier’s RMS power rating is suitable for the woofers (see specifications).
- You will only need to use two channels of amplification.
IMPORTANT: Because of the lower impedance of the drivers, do not wire in parallel or bridge amplifier channels to prevent overheating of the amplifier.

Bi-amping
Crossover sound settings
You can set the crossovers according to your sound preferences.
- You can raise or lower the woofer output by sliding the “TWEETER DB LVL” switch to -1.5dB. OdB, or+ 1.5dB.
- You can use the “TWEETER HZ CUTT OFF” switch to choose to have the tweeter play frequencies from either 2.5kHz and above or 3.5kHz and above.
Mounting the crossovers
Find a location in your vehicle to secure the crossovers that willnot interfere with vehicle operation. If mounting In a door panel, itis recommended that you use self adhesive strips of hook-andloopfasteners.
