Not enough bass output

[Kyle Lorenz]

My dad owns some old (but still very good sounding) Audiosphere towers. They are very big, consisting of two 12 inch woofers each. Now, to power these I bought a Pioneer reciever and it does it well but it's lacking in the bass output. I know these speakers can handle more bass as the woofers are hardly moving. I got my fronts at large and bass tone at +6 (the highest). Is there anything I can buy/do to raise the bass output? Thanks.

just a couple of guesses

Depending on the actual receiver, it might not have enough power to bring out the best in the speakers.

Or, are these home speakers or were they sound reinforcement (PA) units? If the latter, they might not go as low and loud as you would hope.

But, since I have never heard of this brand so I'll stop here.

Besides what markw said, not all speakers, even with 12" drivers created equal. Yours may not be able to handle power if the cone excursion is limited, and, it may not be able to handle the low frequency stuff well at all.
And, in the older days, that was common. Your best bet for loud and deep bass is a powered sub.

Are the speakers a Canadian brand? The name sounds familiar.
