How low do they go?
Of the 30 here with a figure quoted, most are rated between 24Hz and 70Hz, with a median of 42Hz. 15 of them are quoted at 40Hz or below, which is roughly where a soundtrack's low effects and the bottom of a bass guitar live. Makers measure this differently, so use the figure to rank models rather than as a promise.
What do they cost?
Most sit between $1,000 and $85,999, with a median of $21,500 and a full range of $499 to $99,999. These are the current asking prices we hold, not sale prices, and they move - check the retailer before deciding.
Do I need an amplifier as well?
No. That is the point of the class - the amplifier is inside the cabinet, so a source connects straight to the speaker. The built-in amplification is mostly 100 to 670 watts, median 400 watts. Manufacturers quote powered-speaker wattage inconsistently, so read it next to the cabinet size rather than on its own.
How big are they?
Most are 825mm to 1,561mm tall, median 1,003mm, and weigh 16.2kg to 77.0kg, median 36.0kg. Every listing gives height, width and depth in both inches and millimetres, so measure the space before you order rather than after.
Do I still need a subwoofer?
12 of the 30 with a figure quoted reach 35Hz or lower, so many of these need no subwoofer for music. For films it is a different question: the lowest effects sit below where most towers stop, and a subwoofer you can position independently is easier to integrate with the room than a tower that also has to be placed for its midrange and treble.
