User questions & answers

Question:	I have a chevy s10 2000 single cab and I wanted to know if it will fit in the back of my seat. what box should I get to fit my truck
Answer:	I never measured it but the system is designed to maintain nominal load under all conditions. Mine works fine on a whole house system with all outputs wired. Keep the same speakers per load connected, i.e. use only 8 ohms speakers.
Question:	Why are they making a popping rattling noise
Answer:	A "passive' subwoofer (no internal amplifier) is just a speaker with a low pass crossover, which would be fine. If you have a "powered" subwoofer, you would use a line level audio signal from the amplifier line out, not a speaker output [even though that is also possible with some powered subs with input attenuation].
Question:	What is the recommend air space for these
Answer:	I think Mr. P means to ask if it uses autotransformers, which can be used in audio applications to adapt speakers to constant-voltage audio distribution systems, and for impedance matching such as between a low-impedance microphone and a high-impedance amplifier input.
Question:	Does this come with a grill
Answer:	It does not require any power.

Product features

Alphasonik Subwoofer Innovation

The Treis Series shallow mount subwoofers are designed to deliver true subwoofer sound in a form that has a mounting depth of 3.54'. Alphasonik engineers recognized that there are scenarios where you just can't fit a full size subwoofer behind the seat in a pickup truck, in convertibles, in the trunk with golf bags, strollers, or whatever other assorted goodies we drive around with. Other shallow mount subwoofers in the market are not able to deliver true subwoofer performance, they are more like mid-bass drivers, unable to play those truly low notes that make owning a subwoofer fun.

Design

The Treis series was designed with a Spun aluminum cone fore accurate and ground breaking bass. Also, Alphasonik engineers added EPDM Surround for Enhanced control at Extreme Temperatures.

Product description

The Pioneer A Series of Shallow Mount Subwoofers uses a highly rigid cone made with MICA injected molded resin which creates a rigid and durable cone. This gives them the ability to produce accurate bass. The TS-A2500LS4 10 in. shallow mount subwoofer has multiple, patent-pending features that deliver the big bass performance of a full size subwoofer, but in a compact design that can be installed either behind or under seats, depending on the type of vehicle.

• 10 in. subwoofer
• 1,200 watts max, 300 watts RMS
• Frequency response: 20 Hz to 900 Hz
• Unique design with just 3-3/8 in. mounting depth
• Small enclosure use (.35 to .7 cu. ft.)
