I have a Onkyo Model HT-S5300 I can to install two additional front speaker I want to know the speaker specification that i can install

The speakers and amp are optimized at 6-ohms. Adding speakers will require you to run them in parallel with a possible dangerously low impedance; or in series, doubling the impedance which is safer.

These products are not designed to be modified.

I bought an onkyo hts-5300 it has grave reviews for sound. Yet it is not producing what i feel it should,what is the ideal db setting for the speakers for crisp sound and deep theatre style bass

"Grave" reviews??

If you set it up as specified in the manual it will be optimized. As far as volume settings while listening go, that is subjective and entirely up to you, your speakers and your neighors.

Onkyo ht-r500 no speakers attached goes directly into protect mode, standby light blinking..

I have a HT-R520 - First thing stated in the manual is 'Do Not Apply Power to the System Until All the Speakers Are Connected to the Receiver.' This practice avoids any hot connects to the speakers. As with any high-outpiut system connecting spreaker wires to the system while in operation can spike the speakers as well as the amplifier curcuits. Hook up your speakers first and give it a try. Good Luck!

Center speaker will not work

If you had the Speakers Set to A (not B) and no headphones connected when you pressed the TEST TONE button on the Onkyo HT-R540 (also known as the HTS-790) remote, and you had no sound from the Center Speaker then try the following steps. 1) Check the Center Speaker wiring at both ends under a bright light and make sure that there is not a strand of wire touching the Receiver Chassis or another speaker post. Check both + and - . If that looks okay, 2) unscrew the Center Speaker Post connections on the Receiver and verify that the bare stripped wire is making contact. Often, the insulation is too far into the connector. When screwed down, the wire's insulation is crushed and keeps the bare wire from making contact. If this looks okay and the unit is under Warranty, your last test is to: 3) temporarily swap the wires from the Center Speaker with the Right Front Speaker. Turn the volume down low and try the TEST TONE button again. If you now hear sound from the Center Speaker box itself and none from the Right Speaker box, then the Receiver is the problem. If you still do not hear sound from the Center Speaker box, then the Center speaker itself is defective.
