Read the guideQuad 10 Inch Subwoofer Box Questions
How many chambers does a quad cabinet have?
Two. A bonded full-height centre divider splits the cabinet in half and each chamber carries two drivers, both lined with polyfill. The two drivers in a chamber share its volume; the two chambers do not share with each other. The listing states the total net volume and the figure per chamber.
Is the net volume per driver or for the whole box?
The headline figure is for the whole cabinet. Each listing also gives the per-chamber volume, which is what each pair of drivers is working into and the number the alignment was solved from.
How wide is a quad 10 inch box?
Every cabinet here is 44 inches wide. Four 10 inch cutouts plus the baffle material and dividers between them do not fit across less, so there is no narrower version. Measure the narrowest point of your opening at seat-back height before anything else.
What impedance will four subwoofers give me?
Each chamber has its own terminal cup, so you choose the coil wiring on each driver and then how the two cups are joined. With the cups in parallel, four dual 4 ohm drivers reach 2 ohms with the coils in series or 0.5 ohms with them in parallel; dual 2 ohm drivers reach 1 ohm or 0.25 ohms. Putting each chamber's pair in series, or the two cups in series, lands on 8 and 2 ohms instead, or 4 and 1. Match the final load to the amplifier's minimum stable impedance rather than chasing the lowest figure. Calculate impedance for multiple subwoofers works through any set.
Can I run different subwoofers in one cabinet?
No. Run four of the same model at the same impedance. Each chamber is cut for a matched pair, so an odd driver changes both the volume its chamber is working into and the load on that chamber's cup.
Are there ported quad 10 inch boxes?
Not from us. At four drivers the extra volume a port needs no longer fits in the space that made the high driver count worth doing. Vented builds are single and dual cabinets, on the ported page.
Is a quad 10 better than three twelves?
They move close to the same air. Four tens spread it over more motors with less moving mass on each, which starts and stops faster and shares the heat; Three twelves get there with fewer drivers to buy, mount and wire, and a simpler final impedance. What will physically go in the space usually settles it. The dual subwoofer setup guide covers the trade in detail.
