2. Using supplied bolts, attach 
included AC-LA8-BACK back 
plate to rear of speaker. 
WARNING: Do not exceed 
100 in-lbs when installing bolts 
in threaded inserts. 

 

3. Set LA880it on top of 
LA808i and attach supplied 
AC-LA8-LINK-II side plates using 
supplied bolts.

4. 

    Attach supplied 
AC-LA8-LINK-II back plate 
using supplied bolts.

5. Attach included safety 
cables to each bent bracket
(on LA808i-II and LA880i-II),
and secure to the structure
using installer supplied 
fasteners.

 

6. Choose one of two inputs: 
SpeakOn ,

™  or included 

Euroblock. Note: Signal wire 
must connect to LA808i-II. 
Do not connect signal wire
directly to LA880i-II.

   

7. If using Euroblock input, 
connect signal wire to 
four-pin Euroblock plug. If 
using SpeakOn™ connector  
skip to step 10.

   

8. Insert wired 4-pin Euroblock 
jack into speaker. Connectors 
are keyed for polarity. Skip to
step 11.

10. If using SpeakOn™ cable, 
insert the end of the cable into 
the SpeakOn™ input  
connector, and twist to lock.

  

10. Connect included jumper 
cable from LA808i-II output to 
LA880i-II SpeakOn™ input. 
Jumper cable passes the
proper signal from LA808i-II 
to LA880i-II for maximum 
performance.

11.  Flip LFDE switch on 

LA880i-II to "YES". Failure to
flip the switch will negatively
impact sound quality.

12. Done!

LFDE Integration  Instructions

 

NOTE: To further constrain the low frequency beamwidth, two LA808i-II LFDE units may be used. In this case mount one LA880i

-II

 between the two 

LA808i

-II

 units. Wire one LA808i

-II

 and the LA880i

-II

 as described above. Feed the other LA808i

-II

 the same full range signal, but from another amplifier    

channel. Do not wire the two units in parallel unless the amp is 2 ohm stable.

1. Unpack speaker.
