Question about inputs on a subwoofer

[NaOH]

My subwoofer has these extra connections on the back for speakers it looks like. I should be better off bypassing these and using the connections on my receiver right? I was planning on just hooking the two speakers up to the back of my receiver and then sending a single signal to the subwoofer.

depends. Usually you are correct in that the receiver should handle the crossover frequency, but if your receiver doesn't allow you to change the xover frequency to something that matches your mains and sub's capabilities, you may opt to do the pass through method.

Pass through is typically a simple first order high-pass at 100hz. Not very ideal for a vast array of speakers, but it is a last option. Definitely use your receiver's bass management. If your receiver doesnt' have bass management, it may be time to upgrade to one that does.

I have an older denon so I believe it should have the bass management you're speaking of.

You have PSB Alpha B1 right? If so, an 80hz crossover should be good with them as their -3dB point is around 65hz. They also do not require much wattage to get loud due to their 90dB sensitivity. If your denon can handle 4ohm loads without much stress, you are good to go.

Thanks a lot man

ok so I looked at the back of my Denon and where the speakers hook up it says 6ohm and up...is this bad? Also, i can't find a way to set the crossover on my reciever.

BTW I have the Denon AVR 2800

You will be fine as long as you don't really crank the volume. If you hear distortion, turn the volume down.

Since your receiver has preouts, you can buy an external amplifier if you realize you need more power. However, depending on costs, it might be better to get a new receiver if you choose to go that route.

Frankly, I don't think you will have a problem with the power front.

Your receiver should have at least a "speaker = small" setting. On some online reviews, they mentioned that your receiver has highpass and low pass settings from 80/100/120 hz. Just choose the 80hz one if it exists.

I really need to find the manual or a remote for it. I got it second hand from my dad. Damn, I shuold really pull the trigger on an HK
