Adjusting Velodyne Sub

I just got a Velodyne VRP-1200 sub. Sounds great, but it seems that I have to turn it up pretty loud compared to when it was in the store to get the good low end rumble out of the movies. I have it hooked up to my HK 635 receiver on the sub pre out. I have one line going into the LFE in the sub. Should I use the Y connector to run the sub cable into both imputs on the back of the sub to get better sound or is it an issue where I need to change a setting in my receiver? Thanks!

You should get very good sound with Low pass cross over set to 150 and subwoofer vol to 1 o'clock position. You can set up cross over frequency in the receiver too.

On your Receiver setting
Front speakers small (if using bigger speaker you can change it to large)
Rear and center small
Bass out to LFE.

If this does not work you can try Y splitter in Velodyne sub.

150 Hz crossover? Why?

I was kind of wondering that myself.

It all depends on the speakers you have.

I have a pretty basic HTIB from Infinity and my sub needs to have the crossover set a 150Hz! :eek:

It sucks, because the bass it directional this way, but if I don't have it set up like this I miss out on a lot of midrange because my speakers can only handle down to 150Hz.

If you have speakers that can handle down into the lower ranges, 60, 70Hz, you should have your crossover on the subwoofer set to around 80Hz. Anything higher than 80Hz and sound becomes directional which is not what you want with a subwoofer.

A sub isn't meant to reproduce the midrange frequencies. A typically ideal setting is 70-75Hz for the sub, and have your speakers also reproduce frequencies as low as 65-70Hz if they can. That should give you a nice, smooth tone and deep, and especially clean, lows from your subwoofer. Deep and clean because you now don't have the sub trying to reproduce those midrange frequencies above 100Hz, which are really meant for your speakers.

150hz Crossover! Can't really call it a "subwoofer" if its crossover is that high IMHO... Besides, as that link states, the LFE channel doesn't generally have >80hz information anyway.

150 hz cross over because the receiver is set to a lower cross over frequency 80 to 100 depending on speaker size. Using LFE receiver takes the prference on what low frequency to use.

If receiver don't have the capability to set cross over the Sub's crossover could be use.

I see what you're getting at now. In my case, my main speakers have bass extension to ~30hz (-3db) so I have to set my Subwoofer x-over much lower than 80hz.
