Speaker Size 

Many of today’s receivers allow you to tell the receiver what type of speakers you are using.  This is important since you 
don’t want to waste the power across a full-frequency signal to a speaker that can only handle a limited range.  Receivers 
will typically ask you whether or not the speaker is “small” or “large”.  In most cases, setting the speaker to “small” will 
cause only frequencies above 100 Hz to be sent to the speaker.  “Large” allows the full frequency range to be passed to 
the speaker.  Some receivers take this a step further and actually allow you to set the cut-off frequency.  HTD Level ONE 
speakers will almost always perform best when set to “small” or with a crossover point of 100 to 120 Hz. 

 

In many receivers, setting a speaker to “small” automatically sends the low frequencies that would otherwise go to that 
channel to the subwoofer connected to the LFE channel.  Check the “bass management” section of your receiver’s 
owner’s manual to be sure.  This section should also address the options you have for utilizing the powered subwoofer in 
audio-only applications. 
 

Mounting Brackets 

HTD Level ONE Main Speakers include U-shaped wall-mount speaker brackets.  Hardware is included for mounting 
where you have access to both sides of the wall or stud.  You can also attach the speaker brackets to a stud from one side 
using 1 1/2” wood screws.  For safety, always mount these speakers on a wall that is reinforced from behind.  Never 
mount a speaker on a wall made of un-reinforced drywall or plasterboard.  Consult a professional contractor if you are 
unsure.  These speakers can also be placed on bookshelves and most types of speaker stands. 
 

NEVER PLACE A SPEAKER WHERE IT, OR THE CABLE CONNECTED TO IT, ARE WITHIN EASY REACH OF 
CHILDREN OR PETS.  ALWAYS USE GOOD JUDGEMENT AND COMMON SENSE WHEN PLACING A SPEAKER 
WHERE PEOPLE OR PETS WILL HAVE ACCESS TO IT AS SERIOUS INJURY OR DEATH CAN OCCUR IF THE 
SPEAKER WERE TO FALL. 

 

Warranty 

All HTD Speakers carry a five-year parts and labor warranty.  Details of the warranty and return authorization process are
