The SRX700 speakers covered by this manual are not intended for fixed installation in outdoor or high moisture  
environments. Moisture can damage the speaker cone and surround and cause corrosion of electrical contacts  
and metal parts. Avoid exposing the speakers to direct moisture. Keep speakers out of extended or intense direct  
sunlight. The driver suspension will prematurely dry out and finished surfaces may be degraded by long-term  
exposure to intense ultra-violet (UV) light.  
SRX700 speakers can generate considerable energy. When placed on a slippery surface such as polished wood  
or linoleum, the speaker may move due to its acoustical energy output. Precautions should be taken to assure  
that the speaker does not fall off a stage or table on which it is placed.  
Stand mounting safety precautions  
Some SRX700 models include a 35 mm receptacle cup to allow mounting on tripod stands or on a pole over  
subwoofers. When using stands or poles, be sure to observe the following precautions:  
;
;
Check the stand or pole specification to be certain the device is designed to support the weight of the  
speaker. Observe all safety precautions specified by the manufacturer.  
Always verify that the stand (or subwoofer / pole) is placed on a flat, level, and stable surface and be sure to  
fully extend the legs of tripod type stands. Position the stand so that the legs do not present a trip hazard.  
;
;
Route cables so that performers, production crew, and audience will not trip and topple the speakers over.  
Inspect the stand (or pole and associated hardware) before each use and do not use equipment with worn,  
damaged, or missing parts.  
;
;
Do not attempt to place more than one SRX700 speaker on a stand or pole.  
Always be cautious in windy, outdoor conditions. It may be necessary to place additional weight (i.e. sand  
bags) on the base of the stand to improve stability. Avoid attaching banners or similar items to any part of a  
speaker system. Such attachments could act as a sail and topple the system.  
;
Unless you are confident that you can handle the weight of the speaker, ask another person to help you get  
it onto the tripod stand or pole.  
Hearing damage, prolonged exposure to excessive SPL  
SRX700 loudspeakers are easily capable of generating sound pressure levels (SPL) sufficient to cause perma-  
nent hearing damage to performers, production crew and audience members. Caution should be taken to avoid  
prolonged exposure to SPL in excess of 90 dB.

Infrasonic Filter Settings  
It is a good practice to use a High Pass Filter (HPF) to prevent frequencies below the system tuning frequen-  
cy from reaching the speaker. Inputting these frequencies to the speaker will not result in any appreciable  
acoustic output but will put needless mechanical stress on the woofer and reduce available amplifier head-  
room. A High Pass Filter will protect your SRX700 system from excess infrasonic energy with little, if any  
loss of significant program content. Refer to the above chart for infrasonic filter settings.  
Processor Tunings  
System tunings for dbx DriveRack processors have been developed for the SRX700 series. If your  
DriveRack was manufactured prior to the release of SRX700, you may obtain the settings from the dbx web-  
ware_downloads.htm. The tunings are available in digital format and may be loaded directly into your  
DriveRack processor (except DriveRack PA).  
The settings are also provided in a .PDF document for owners of the DriveRack PA. For other processors or  
for analog crossovers and equalizers, the PDF tunings may be used as a starting point. Be aware that all  
digital processor models may not respond identically to a particular setting.  
DuraFlex™ Finish  
The DuraFlex finish used on your SRX700 series speakers is one of the most rugged finishes ever applied  
to a speaker. However, all speaker finishes are subject to damage. Should the DuraFlex finish require repair,  
a touch-up kit (Part Number 30052) is available from JBL Professional Parts.  
Removable JBL Logo Badge  
For applications requiring a more unobtrusive appearance, the JBL badge may be peeled off exposing a  
JBL logo that is cut into the grille. Note that the badge may not adhere properly if reattached.

FLYING AND SUSPENSION  
JBL SRX700 series offers 4 models with suspendable capabilities: SRX715F, SRX722F, SRX725F and  
SRX738F. Before attempting to suspend your speakers, read and understand the following safety information.  
IMPORTANT SAFETY WARNING!  
The information in this section has been assembled from recognized engineering data and is intended for infor-  
mational purposes only. None of the information in this section should be used without first obtaining competent  
advice with respect to applicability to a given circumstance. None of the information presented herein is intended  
as a representation or warranty on the part of JBL. Anyone making use of this information assumes all liability  
arising from such use.

General Hardware Information  
Any hardware used in an overhead suspension application must be load rated for the intended use. Generally,  
this type of hardware is available from rigging supply houses; industrial supply catalogs and specialized rigging  
distributors. Local hardware stores do not usually stock these products. Hardware that is intended for overhead  
suspension will comply with ASME B30.20 and will be manufactured under product traceability controls.  
Compliant hardware will be referenced with a working load limit (WLL) and a traceability code.  
Attachment to Structures  
A licensed Professional Engineer must approve the placement and method of attachment to the structure prior to  
the installation of any overhead object. The following performance standards should be provided to the  
Professional Engineer for design purposes; Uniform Building Code as applicable, Municipal Building Code as  
applicable, and Seismic Code as applicable.  
The installation of the hardware and method of attachment must be carried out in the manner specified by the  
Professional Engineer. Improper installation may result in damage, injury or death.

Inspection & Maintenance  
Suspension systems are comprised of mechanical devices and, as such, they require regular inspection and rou-  
tine maintenance to insure proper function ability. JBL SRX700F loudspeakers must be inspected for fatigue at  
least annually. The inspection shall include a visual survey of all corners and load bearing surfaces for signs of  
cracking, water damage, de-lamination, or any other condition that may decrease the strength of the loudspeaker  
enclosure. Accessory rigging hardware provided with or for the JBL SRX700F loudspeakers must be inspected  
for fatigue at least annually. The inspection shall include a visual survey of the material for signs of corrosion,  
bending or any other condition that may decrease the strength of the fastener. Additionally, any eyebolts shall be  
checked for possible spin-out of the enclosure. For all other hardware and fittings, refer to the hardware manufac-  
turer's inspection and maintenance guidelines for process.  
JBL is not responsible for the application of its products for any purpose or the misuse of this information for any  
purpose. Furthermore, JBL is not responsible for the abuse of its products caused by avoiding compliance with  
inspection and maintenance procedures or any other abuse.  
Prior to suspending the system, an expert, trained and experienced in flying speaker systems should inspect all  
rigging parts and components.

“Basic Principles for Suspending Loudspeakers”  
Safe Rigging  
The JBL SRX700 suspendable version loudspeakers are supplied with built-in internal brackets. The system is  
designed to facilitate the suspension of the loudspeaker by a qualified person familiar with rigging hardware and  
industry practices. Improper installation may result in damage, injury or death.  
Working Load Limit  
The working load limit (WLL) of any JBL SRX700 suspendable loudspeaker will be maintained as long as no  
more than 136 kg (300 lb) is suspended by a minimum of TWO (2) PRIMARY SUSPENSION points (Track  
Suspension), or 46 kg (100 lb) is suspended by TWO (2) of the SECONDARY SUSPENSION points (M10  
Forged Shoulder Eyebolts).  
Flying for Portable Applications (Primary Suspension)  
For portable, temporary suspension of SRX700F models, order the JBL SRX-FF3. This kit includes three detach-  
able fly-clips. For additional suspension components, contact a professional rigging hardware supplier.  
Latchmechanismmust be  
down and fully engaged  
WARNING  
Before lifting any speaker using fly-clip attach-  
ments, be certain that the latch mechanism of all  
fly-clips is fully and properly engaged with the  
track. An audible click will be heard.

Suspension in Fixed Installations (Secondary Suspension)  
For fixed installations of SRX700F models using M10, forged-shoulder eyebolts, order JBL Part number 229-  
00009-01 which includes 3 x 10 mm forged eyebolts with washers.  
WARNING  
Suspension of SRX700 speakers must employ  
both top attachment points. When "bridling" an  
SRX700,two (2) legs of equal length must be used.  
The rear attachment point is a pull-back point and  
is intended only for use in adjusting the down-  
angle of the speaker enclosure. Only the top and  
bottom attachment points are intended for use as  
suspension points.
