Hi All,

I got the VP150 as my centre speaker with the Denon 3808(upgraded firmware).

I would like to know if it better to selece the Centre as
Large or Small speaker in the speaker config in the Amp.

Current setting is at large.

What is the best settings for the VP150?
What difference will there be?

I read in another forum that if you choose small speaker, the lower frequencies will be pass to the fronts or Sub.

For large speaker config, all will be pass through.

Please advice.

Hi Asiatic

This question comes up once in a while, I like to have mine set to large. The VP150 is good to 85 hertz. That should cover most male voices in the lower register, even James Jones (this is CNN, I'm your father Luke, etc). However I am running a sep. power amp with 150 watts. So I have plenty of headroom to handle the lower frequences for the VP150.

Others on this forum will tell you to keep it at small, and since you are using a Denon, that may be the correct thing to do. Much depends on your room dimensions and how loud you like listen to your movies.

Remember it takes more power to reproduce lower freq. then higher. Some here will even tell you to keep you mains set to small. This will put less strain on your Denon. It all comes down how much available headroom you have. The best way to improve headroom is to increase power.

Hello asiatic

I remember reading a post by Alan Loft (resident expert for Axiom audio) recently and he commented about the VP150 and recommended setting it to small in the bass managment settings. Axiom Audio in general sticks with THX in this matter and reccomends all speakers set to small and and the crossover set to 80. However, not everyone does that, ultimately it is up to you what sounds best.

Cheers

Small definately, no reason to pass full freq's to the center. The center is for dialog so really no reason to set it to large, if your using around 80hz crossover.

Asia, any speaker set "small" is rolled off below the selected crossover frequency and those frequencies are then handled mainly by the sub. Assuming that you have a good sub, the VP150 and all your other speakers, including the mains, should be set small, with a crossover frequency of probably 80Hz. This allows the sub to handle the frequencies that it does best(if it's a good one)and allows the speakers to play more cleanly where they do best higher up in frequency.

What did Audyssey set it to? Chances are it set it to small with a 60 or 80hz XO, I would run it this way.

John and Jakewash are probably right here. Looks like I should try to change some settings.

Careful going by Audyssey. They don't get to choose large vs. small. The AVR manufacturer does. Some, like Onkyo (maybe not this year's models) make any speaker capable of 80hz Full Range (large). Others, like Denon use 40Hz. Audyssey always recommends changing to small and crossing over at 60Hz or higher.

So if we set the M80s and VP150 to small and do not have a subwoofer in the setup (yet), we will miss those frequencies?

What is the optimal setting for Axioms if no sub is connected?

Hi Asiatic,

Set your VP150 to Small. The VP150 is NOT a full-range speaker. In fact, most centers and surround speakers do not have useful bass output below 80 Hz.

Setting your VP150 to Large risks overdriving the woofers by routing low frequencies to drivers that are not intended to reproduce them.

There's no point in setting the centers to Large when lower frequencies are handled far more effectively by a subwoofer or the woofers in your main speakers if you don't have a subwoofer.

Don't rely on auto-setup systems to determine the Small-Large settings. With the vagaries of room standing waves and errors in frequency response readings of auto-setup mikes, you are far better off to manually set the Small/Large settings.

Regards,
