As you may or may not be aware, I’m a bit of a home cinema addict. I’d been a bit dissapointed recently with my front speaker setup, the center channel was a bit “thin” and the sub was a bit boomy and felt disjointed from the main speakers. A week or so back I added an additional matching center speaker wired in parallel to improve things a bit. This seemed to help quite a lot, the center channel now sounds a more forthcoming. The sub however was still a problem.
During a quiet hour today I set about tweaking things. This was partly inspired by reading some threads over on A V Forums about speaker setup. First off I told my amp that my front speakers were “small” instead of “large”, this redirects some of the bass from the main speakers to the sub, I left the crossover point at the default 120Hz. Then I turned my attentions to the sub itself. It turns out that I’d managed to mess up the subs own setting for the crossover point, I’d set it at 50Hz instead of 150Hz, this meant (as far as I can tell), that there would have been a hole in the frequency response of the front speakers where the sub was effectively ignoring anything above 50Hz. I set that to 150Hz and things improved immediately. I also lowered the volume on the sub which also improved things dramatically.
The final result was a much more cohesive sound from the front speakers. Most of the calibration was done whilst listening to the new Half Man Half Biscuit album mentioned elsewhere. I can now listen to CD’s using the sub as well as the main front speakers and the sound is far improved. Before the adjustments I bypassed the sub.
To test this all out in full 5.1 mode, I decided to give everything a full workout by watching Fight Club on DVD, the end result was fantastic.
