SQ is much more difficult to quantify than say, SPL , the sound pressure level (the boom in subwoofer ). Although there is no hard spec that identifies SQ, it is always good to talk about sound quality in a car sub. Are two subs better than one? The answerto this question is typically yes, assuming you’re comparing one vs. Inalmost all circumstances, installing multiple subwoofers in your theater roomwill yield significantly better and smoother bass response across a widerlistening area due to modal averaging.

It has 10ft ceilings and is open to the restof the house which makes it quite challenging to get good sound in, let alonerespectable bass response. For the pastthree years, I was using the venerable Axiom EP5subwooferlocated towardsthe left front of the room behind one of the couches. For a single subwoofer installation, I foundthis to be the best location for performance and aesthetics as the couch andblinds did a great job hiding this beast. Consideringthe room dynam.

But what the manufacturer is not showing you is the bandwidth vs. SPL output of both subwoofers in their spec sheet. In fact, it’s interesting to note they show you a graph for the EP5but not the EP400.

With theEP50 the bass was well extended and tactile but not particularly as tight asI’d like it. Switching over to the dualEP400s was a real eye opening experience. I noticed that the bass no longer sounded like it was emanating from thefront left of the room but instead sounded like it was coming dead center nearthe plane of the main speakers. The dualEP400s were creating that “virtual” subwoofer effect making it hard to pinpointexactly where the subs were.

The effective bassresponse of the dual EP400s was much tighter with a lot more mid basspunch. I was definitely down with theimprovement I was hearing from the dual sub system. This is howbass should be! I searched out some bass tunes popularized by. The difference between a subwoofer and a speaker is the frequencies they project.

While the average speaker plays between 20Hz to 20kHz, on the other han subwoofers amplify low toned sounds typically below 100Hz. These offer 0watts of power along with 1- Ohm impedance and dual coils, and they also have a mounting depth of inches. These car subs makes them one of the best sounding and user friendly woofers available.

You can now produce bass with more punch and extension. Check out HalfPriceCarAudio. SPL Subwoofers that utilize the latest technologies so you can get great deals when you buy one!
