The Klipsch Heresy have large woofers even for a floor-standing speaker and surprisingly, the bass performances were more accurate and agile than expected. Klipsch Heresy’s overall bass performance is clean and taut, the low-ends don’t overshadow the upper registers and provide the texture to make the musical instruments sound authentic. The bass accuracy of the Klipsch Heresy floor-standers is certainly impressive but they don’t go deep enough into the bass extension. When it comes to subterranean low frequencies, the Heresy speakers are unable to prominently produce it.
If you listen to music and/or watch movies with bass-heavy soundtracks, you might want to integrate a powered subwoofer into your sound system. The job of the subwoofer will be to produce the missing bass extension where the Klipsch Heresy speakers are unable to deliver. Other than finding a subwoofer that will match well with the Klipsch floor-standers sonically, your own requirements will also play a major role in choosing the powered sub. We will be going through a list of requirements and you might want to consider them.

Subwoofer Requirements
To match the Klipsch Heresy bass performance, we suggest going with sealed cabinet subwoofers as their tighter bass delivery and higher accuracy will fit nicely with these floor-standers. Sealed subwoofers are also ideal for music playbacks due to their articulate subsonic bass performances. If you prefer higher bass output and SPL then a ported subwoofer will be a better option. Since you are using Klipsch Heresy floor-standers, you are likely playing them inside a mid or large-sized room. You will need a powerful and large subwoofer in order to fill the space with immense sonic energy, especially for a big room.
Bigger and more powerful subs would cost more, you should work out an amount you are willing to invest on a subwoofer. You should also get a subwoofer that could reach down to 20Hz bass extension or even lower so as to get full-range sound reproductions from your system. If your listening room is just too big and your amplifier is capable of connecting up to 2 subwoofers, we suggest going with dual subs set-up as this will help cover the space with bass evenly. These are some of the subwoofer requirements you should consider. You might want to take some time to add more requirements to the checklist.

Auditioning of Subwoofers

Do use bass-heavy soundtracks you are familiar with so you can easily detect the improvements you are hearing. This will also make it easier to compare the difference in bass quality and performance of each potential subwoofer.
