AndyS,

I understand your point now about not "optimal". Going with a mono sub when one has large main speakers would indeed accentuate/duplicate the bass information, hence the name "bass-heavy".

Unfortunately, I can think of no ideal setup for integrating a sub with large, i.e. full range, main speakers.

The options with respective drawbacks:

1. Mono sub - accenuation/duplication of bass information below the crossover point. Probably acceptable for movies but would cause bloated bass for music. Not available as an option when using more than one sub.

2. Centre sub - main left and right speakers are left full range but no bass information from the front channels is sent to the sub. May be acceptable for music. But, most large "full range" speakers like mine still only go to 30hz, so very low bass in the 20 - 30hz range in the front channels will be lost.

3. All "small" speakers with mono sub - could set full range main speakers to small and cross over into the sub thus keeping the very low bass and avoiding accentuation/duplication of bass. But, the full range main speakers would be crossed over at the same 80hz level as my small centre and surround speakers and therefore not used to full advantage.

These issues are simple software fixes and need to be addressed by Meridian in a timely fashion. I have already written to them about the lack of a mono sub option when also using a surround sub and am waiting for a reply. The "3." entry above is probably the most viable option for a system of this type but would require separate, individually adjustable crossovers for the large main speakers and small centre and surround speakers. I hope M is reading this.

Any thoughts from the forum?
