INFINITY 12” Sub Woofer Tube PRIMUS 1500T

Description

Key Specifications

Features & Build

• Ported/enclosure design (“tube”): The tube or port helps reinforce the low bass frequencies (helps boost bass around tuned frequency) while keeping the subwoofer slimmer in one dimension (often helps installation). Car Concepts Shop+1

• Polypropylene cone + rubber surround: These materials are often used in such subs for durability, decent performance, resistance to moisture, heat, etc. hottracks.in+1

• Molded steel woofer grill & “rear aero vent bass system” are among the mechanical / structural features listed to help with protection & airflow. Car Concepts Shop+1

What to Expect in Real Use

Strengths

• Because of the 12-inch size and tube enclosure, you’ll get solid bass output, especially in mid-bass / lower bass (35-60 Hz region) if the amp and power are good.

• The relatively high peak rating allows for good bursts (when music demands it) without clipping (assuming amp is up to spec).

• The enclosure makes mounting easier compared to having a large free-air sub or a large sealed box; often simpler to fit in trunks or behind seats.

Limitations / What to Check

• Even with a tube/ported design, bass below ~35 Hz will be weak — it’s not going to reach the lowest organ / sub music depths. If you want earth-shaking lows, you’ll need a sub with large enclosure or multiple subs.

• You need a good quality external amplifier that can deliver ~300-400 W RMS into the appropriate impedance (2 or 4 ohm) so the sub performs well without distortion.

• Tube subs can have more “port noise” or “chuffing” if the port is not well designed or if volume is too high. Also, enclosure sealing (where needed) and mounting securely matter a lot.

• Large depth (tube length ~66 cm) may be awkward in small cars; measure your available space.
