Home subwoofer question?

Question

hi this is a question for subwoofer and receiver pro.i have a cerwin vega lw-12 subwoofer 150 watts and a yamaha rx-v2700 receiver.we have just moved into a new house and i was setting up sound system and testing and the subwoofer that sounded so awesome and powerful in the old house now sounds awful in the new house.but i must note that this new room im using is double the size of the old one.sub is in the corner like i did at the old house.but bass now sounds distorted and fluttery.everything seems ok until some low frequency effects kick in and thats when the distortion and fluttering happen.the movie incredibles sounded brutal at the old house now the movie on deep bass lines is awful.using sub out to receiver.have bass crossover on receiver set to 80hz.have all speakers set to small.and bass out to sub.and yes i tried to turn crossover all the way up on sub to disable it and use receiver crossover then that made the sub extremely boomy so i turned it back down.any suggestions?

Answer 1

Place the Subwoofer near the wall,below the TV set.Check the setting of hometheatre in bass section.

Answer 2

I suspect you have "standing wave" issues with the sub placement that is causing reflections to meet at your chair in a bad way.

Do this:

- Make a long subwoofer cable from CATV coax and "F-to-RCA-Male" adapters from Radio Shack.

- Move the main seat out of the way and put the subwoofer where you normally sit.

- Disconnect the other speakers and fire up a bass-heavy CD

- Crawl around the wall near the intersection of the two longest, un-broken walls and LISTEN.  You will find spots where the bass is loud/rough/boomy, and other spots where it is smooth and tight.  Mark the smooth/tight positions with a bottle of beer.

Note: These positions will likely be 2/5 or 1/3 along the wall.

Then - reconnect the other speakers, put the sub in one of the marked positions, open the beer and listen.  If the sound is not great there, try the second or third spots.

Eventually you will find the better position for the sub - or be drunk enough you wont care.  This is a Win-Win situation.

Also: sometimes you do need a bigger sub for a bigger room volume.  Look into SVS woofers or HSU Research - two well respected, internet brands.

Answer 3

The pitfalls of room frequencies and resonances are what you are experiencing.

One thing is that your sub amp may not be powerful enough for your new room, due to the larger dimensions of your room. But I don't foresee this as being a major problem.

What I would do  set everything back the way you had it in the old room, and move your sub around the room, experiment different locations until you get the sound you have come to like. Sometimes the middle of the room sounds better than corner placement for sub placement. Good luck.

Answer 4

A few suggestions:

Move it away from the corner a bit

If you have hard floors, concider putting a rug under the sub

Also, if the sub has a phase switch, try flipping it.
