What do you crossover your subwoofer at?

80hz

remember that its transitional not all at once so there is information below 80 from your speakers and above from your sub

so its good to cross even a full octave above what your speakers can handle

ie; Cornwalls dig to 38hz,one octave would be a crossover at 80. Just make sure that you have a sub powerful enough to keep up with your mains

I have all my speakers set to small with a RSW-15

I set all of my speakers as small with a crossover of 80 Hz. The RF-7s put out so much bass at 70 to 80 Hz that my Velodyne SMS-1 does not start to bring in the RSW-15 until 63 Hz. (I bypass the crosover on the RSW-15.)

I agree that the mains need to play on full octave below the crossover point.

I don't understand the sonic advantage of crossing over an octave above your main speakers rated low frequency point. most crossovers are at least useing a 6db per octave slope, so even with speakers that are rated -3db at 60 hz you should be able to get a very good blend with an 80 hz setting, in fact the natural rolloff of such a speaker should produce less problems caused by overlapping.i would even try a 60 hz crossover setting with this speaker myself. i do kind of see your point from a powerhandling/distortion aspect with a small bass driver, but an efficient speaker with robust drivers(klipsch), shouldn't matter i would think.

Both points are valid. I think it depends on your particular set-up, which method works best for you. It's all a compromise. Low x/o gets you more flexibility with sub placement, while a higher x/o should get you lower bass distortion and higher output.

For full range Klipsch Heritage, this is what I do.

I set the sub at 80hz, why, because that is a normal soundtrack standard. This way you don't mess with the .1 sound effects at all.

I then run the Mains in large mode, telling the processor NOT to remove any of the low freq from going to the speakers to get the nice full range Heritage sound.

Nope, I meant large...even though it goes against what the "textbook"

says. I think it has a lot to do with the signal going through less

circuitry and some of the psychoacoustics involved with stereo bass and

the inherant distortions that make the subwoofer too localizeable.

lol, well small does have less FMD - it'll be at least a 3-6dB reduction.

This is one of those things that you really need to listen to both ways

and then decide for yourself which you prefer. I can think of even a

few more variables to consider - but really, since it's so easy to test

there really is no reason to way overthink everything (even though it's

fun).

80hz mains set to large and bass out set to both(fronts+sub). Works very well in my room.

60hz crossover with mains set to large and Mains+LFE for bass control.

This sound the best in MY room.

Yeah, it's one of those try-it-and-see things. 80 Hz/Large/Mains+LFE is what I like best for my stuff.

I'm not sure if I am doing mine right but I have the following setup:

Mains: La Scala's

Center: KLF-C7

Rears: Chorus

Sub: SVS 20-39CSi (Passive)

Acurus A200X3 drives the front soundstage

Denon 4800 drives the rears and rear surrounds

Samson amp drives the Sub

I have all speakers set to Large with the exception of the Center (which is set to Small)

Everything feeds thru an Outlaw ICBM with the following settings:

Fronts: 60db

Center: 80db

Rears: 60db

Can someone explain how this works and if this is what I should be doing with this configuration? It's been a while since I got into my HT setup and I have been focusing more on my 2-ch.

Thanks,

Mike

PS. I hope I am not hijacking the thread, and if so apologize.

Before our nice modern processors, I remember tips pointing out that you should crossover 10-15 HZ over the low end of your speakers.

With LaScallas Belles I could see 60 working nice.

Khorns, maybe 45-50 Hz.

I still think 80 is best as that is what most soundtracks use as there standard reference.
