Phonocar bass reflex tube set 75mm 27cm and 15cm with anti-turbulence rim 04951

The Phonocar 04951 port tube set is a universal accessory for loudspeakers with bass-reflex enclosures. It includes two tubes with a 75 mm diameter, one 27 cm and one 15 cm long, along with two anti-turbulence flanges. This lets you tune the bass-reflex system to suit your enclosure size and the sound you want.

The two flanges reduce air turbulence at the port opening, so there is less noise at high volume and the low frequencies stay cleaner and less distorted. The set is made of durable plastic and is designed for long-term use in car audio systems and home speakers.

The universal design fits almost any speaker or subwoofer enclosure, and installation is straightforward, so beginners can fit it without difficulty. It is especially suitable for DIY speaker builders and anyone who wants to improve the sound of their loudspeakers.
