Turbosound TA890L for Sale | Dual 15″ Horn-Loaded Aspect Low-Frequency Enclosure

The Turbosound TA890L for sale is a professional dual-15″ horn-loaded low-frequency enclosure from the Turbosound Aspect Series. Designed specifically to work with the TA890H mid/high cabinet, the TA890L uses two high-power 15″ neodymium drivers with Turbosound TurboBass technology and integral flying hardware for professional touring, festivals, arenas, theatres, clubs and large-format PA systems.

Turbosound Aspect TA890L Specifications

The published Aspect specifications confirm 1,100 W RMS handling, 101 dB sensitivity, 45 Hz–250 Hz response and 132/138 dB continuous/peak SPL.

Dual 15″ TurboBass Low-Frequency System

At the heart of the TA890L are:

2 × high-power 15″ neodymium drivers

The drivers are loaded using Turbosound’s TurboBass architecture. The manufacturer designed the enclosure to deliver high-efficiency low-frequency reinforcement while remaining compact enough for modular touring applications.

Neodymium magnet structures also help reduce cabinet weight and power compression compared with heavier traditional driver designs.

1,100 Watts RMS Power Handling

The TA890L is rated at:

1,100 W RMS

with approximately:

2,200 W program power

This makes it a substantial professional bass enclosure for large PA applications.

45 Hz – 250 Hz Frequency Range

The published frequency range is approximately:

45 Hz – 250 Hz ±4 dB

Within the complete TA890 system, Turbosound documentation describes the TA890L as covering the low-frequency section and being designed for beneficial coupling when several cabinets are deployed together.

For deeper sub-bass reinforcement, an appropriately configured dedicated subwoofer such as the TSW218 can be incorporated into the wider Aspect system.

132 dB Continuous / 138 dB Peak SPL

The TA890L offers substantial acoustic output:

132 dB continuous

and approximately:

138 dB peak SPL.

Combined with its 101 dB sensitivity, this makes the enclosure suitable for demanding professional applications where considerable low-frequency headroom is required.

Designed to Match the TA890H

One of the most important features of the Turbosound Aspect TA890L is its integration with the:

Turbosound TA890H

The TA890L and TA890H share the same approximate cabinet dimensions and compatible flying architecture. This allows low-frequency and mid/high enclosures to be incorporated into the same professional Aspect cluster.

A complete system can therefore combine:

TA890H – Mid/High

TA890L – Low Frequency

TSW218 – Sub-Bass

depending on the required configuration.

Integral Flying Hardware

The TA890L was designed with integral rigging hardware for professional deployment.

It supports both:

Vertical flying

and

Horizontal flying

configurations and can be clustered with TA890H enclosures. The cabinet hardware also supports secure ground-stacked arrangements.

Any used flying hardware should be professionally inspected and approved before overhead deployment.

Ground-Stacked Configurations

The TA890L does not have to be flown.

Turbosound specifically designed it for either:

Ground stacking

or

Flown arrays

and multiple TA890L cabinets can benefit from low-frequency coupling when deployed appropriately.

This gives professional system designers flexibility when adapting the PA to different venues.

Touring-Grade Cabinet Construction

The TA890L uses a robust professional enclosure designed for repeated touring use.

Published dimensions are:

795 mm × 477 mm × 574 mm

with a net weight of approximately:

68 kg / 150 lb

The enclosure uses professional Neutrik Speakon NL4 connectivity.

Turbosound also designed the cabinet dimensions around practical truck packing for common European and US touring vehicles.

Professional Touring Applications

The TA890L was developed specifically for demanding professional sound reinforcement.

Manufacturer-listed applications include:

• Touring
• Festivals
• Stadiums
• Arenas
• Regional concert touring
• Theatre
• Corporate events
• Dance clubs

This makes the cabinet particularly attractive to professional rental companies and venues already operating Aspect equipment.

Amplification & DSP

The TA890L is a passive enclosure and requires suitable professional amplification and loudspeaker processing.

Turbosound’s Aspect documentation lists amplifier families including MC² E Series and Lab Gruppen FP Series, while tested digital controllers included the Turbosound LMS series and XTA DP-series processors.

Exact amplifier power, crossover, limiter and DSP settings should always be matched to the actual system configuration.

TA890L Technical Summary

Why Buy a Turbosound Aspect TA890L?

For professionals maintaining a classic Turbosound Aspect inventory, the TA890L remains interesting because it combines dual 15″ drivers, horn-loaded TurboBass technology, high efficiency, substantial SPL capability and integrated rigging in a relatively compact professional enclosure.

It is particularly valuable when paired with matching TA890H cabinets because the two models were engineered as complementary components of the same Aspect touring system.
