Bang & Olufsen system - extended BASS ! - I need some tips & tricks -

11 replies

Hello guys,

I need your expertise in order to see if I can add more bass to my system without spending a lot.
I own a B&O system formed from 2 x Beolab 4000 speakers ; 2 & Beolab 6000 speakers and a Beosound Ouverture unit.

The system has a great sound , but I do feel the lack of bass when I raise the volume (due to the ABL system I suppose). I wanted to know if I can connect a Beovox CONA subwofer to my system using a Beolink converter or any other equipment ? I looked at the Beolab 2 prices but they are over my budget right now :( and I can't afford to buy one in the next couple of months . Do you think I'll loose the sound quality If I use the CONA subwofer  ?

Any advice from you will be much appreciated as I didn't hear the sub and don't know the sound quality for it.
 

Thanks a lot,
Stefan 

I use a KEF PSW 2500 active sub in my surround setup.

Don't get a cona, get another brand's active sub instead (you could start with a magnat appr. 80 euro). Search for sub or subwoofer on the forum, lots of different types have been discussed/recommanded.

Thank You very much Ralph.

What would you recommend on a 200 GBP max price ?

Should I buy an active subwofer as well ?

How can i connect the sub to the system if it is not B&O . As I know, the beolab speakers should be run through the sub first in order to filter the bass from them . This way the sub could reproduce the low frequency acoustics and the rest of the speakers to reproduce the high ones.

Am I right ?

 

Thx for the feedback.

Regards,

Stefan 

Welcome to Beoworld!

 There have been a few threads on similar topics. Does this help?

Hi Stefan,

the non-B&O sub has to be connected in parallel. Be sure that you buy an active sub. The connection is described in the reply above. You can connect left AND right channel to your sub if it has a stereo input.

You can not run the beolab speakers through a non-B&O sub. In general this shouldn´t be necessary as the sub is only reproducing low frequencies and the beolab speakers are only reproducing "higher" frequencies depending on their specifications.

When you look for a sub, you should pay attention to its adjustments. It should provide 3 settings:

1. Volume

2. Crossover frequency (to determine, up to which frequency the sub shall work; also to avoid that certain frequencies are reproduced by both the sub and the beolab speakers, which would result in an undesired increase of volume at these frequencies).

3. Phase (to compensate the distance between the sub and the beolab speakers. Cheap models provide 0 or 180 degrees, better models provide a continuously variable adjustment.

As stated already above, you will need an active sub. Look for a sub that is made for HiFi rather than for video purposes as the first are more precise and the latter only produce "rumbling"...

Thx a lot for the feedback Hagen. It really got me out of the darkness.

This forum is indeed a special one.

Would you please recommend me an active sub that should best fit my system described above ? with 4000s and 6000s ?

 
Regards,

Stefan
 

any opinioin on the sub model that I should try and respect Hagen's recommandations above ?

I am using a Canton AS 40 SC - but this is out of date and that is why I did not give any recommendation...

Furthermore its transformer is producing a slight hum - even when it is not working. That is why I would go for a sub with ICE amplifier. Why don´t you go to a hifi shop and check some subs for yourself?

Hi ,

    The problem is that the Hi-Fi stores in Romania don't think about clients that heard the warm sound of  a speaker and good sound quality at least once.

     Everyone is selling those Sony /Panasonic/LG .. crappy systems made in China that will damage your ears when you're trying to change the volume. I hate all the products made in the bathroom of a container ship that sales to europe

     I also don't know many companies that produce good active subs. I am having second thoughts now because I red the Beolab 2 has a good filter in order to release the presure from the other speakers that are trying to play the low frequency sounds. 

     Can I find something that has nearly the same performance and doesn't cost 3000 eur :) ?

Regards,

Stefan

Hi Stefan, nothing like the BeoLab 2 subwoofer! Save, and purchase it, well worth it! I did, and man does it make a difference...

Paul
