Turbosound TSE115 for Sale | 15″ TurboBass Low-Frequency Enclosure

The Turbosound TSE115 for sale is a classic professional low-frequency loudspeaker enclosure from Turbosound’s modular TSE Series. Built around a single 15-inch low-frequency driver using Turbosound’s TurboBass loading principle, the TSE115 was designed to reproduce the bass and low-mid region in professional PA systems while maintaining high efficiency from a relatively compact cabinet. Original documentation rates it at 250 W RMS / 500 W program, with 8-ohm nominal impedance and approximately 101 dB sensitivity.

Turbosound TSE115 Specifications

Period Turbosound product information confirms the TSE115’s 250 W RMS rating, 65 Hz–500 Hz response and compact low-frequency design.

Single 15″ TurboBass Design

The TSE115 uses:

1 × 15″ Low-Frequency Driver

rather than the dual-15″ configuration of the larger TSE215.

Turbosound describes the cabinet as employing its patented TurboBass device, which uses partial horn loading to control the driver and improve low and low-mid projection.

This architecture makes the TSE115 particularly useful as a compact bass or kick/low-mid component within a larger professional system.

65 Hz – 500 Hz Frequency Response

Published Turbosound range information gives the TSE115 a frequency response of approximately:

65 Hz – 500 Hz ±3 dB

This clearly positions the TSE115 as a low-frequency enclosure rather than a standalone full-range loudspeaker.

It can therefore be combined with compatible mid/high cabinets and, where deeper sub-bass is required, additional dedicated subwoofer enclosures.

250 W RMS / 500 W Program

Original specifications rate the TSE115 at:

250 watts RMS

and

500 watts program

with a nominal impedance of:

8 ohms

Although the wattage appears modest compared with many modern loudspeakers, the cabinet’s relatively high sensitivity is an important part of its performance.

101 dB Sensitivity

The TSE115 is rated at approximately:

101 dB at 1 W / 1 m

with published peak output around:

129 dB SPL

Turbosound specifically highlighted the cabinet’s efficient electrical-to-acoustic conversion as one of the benefits of its loading design.

Compact Professional Bass Cabinet

The TSE115 was developed as part of a modular system where different enclosures could be combined according to the application.

Its approximate dimensions are:

578 mm high × 430 mm wide × 578 mm deep.

This relatively compact footprint makes it useful where traditional professional Turbosound performance is wanted without moving to a much larger dual-driver enclosure.

Part of the Modular TSE Series

Turbosound developed the TSE range as a collection of complementary professional enclosures.

The range included models such as:

• TSE111 mid/high
• TSE211 mid/high
• TSE115 bass
• TSE215 bass
• TSE118
• TSE218
• TSE260 high-frequency enclosure

The TSE115 and TSE215 were specifically introduced as bass enclosures for the modular installation system.

TSE115 vs TSE215

For buyers comparing the two classic TSE bass models:

The TSE215 essentially provides a larger dual-driver alternative where additional output is required.

Professional Applications

The Turbosound TSE115 was intended for applications including:

Main PA systems

Sound contracting

Point-source clusters

and other professional installations.

Today, used examples may also appeal to buyers building classic club systems, restoring older Turbosound rigs or expanding an existing TSE inventory.

Amplification & Processing

The TSE115 is a passive professional loudspeaker and requires suitable external amplification.

For vintage cabinets, the amplifier and DSP configuration should always be matched to the drivers actually installed in the offered unit.

This is particularly important because older TSE cabinets may have been reconed or fitted with replacement drivers during their service life.

Condition & Original Components

When selling a used TSE115, it is useful to specify whether the cabinet has:

Original Turbosound components

Reconed original drivers

or

Replacement drivers.

The product listing should also identify the condition of the cabinet, grille, connectors and any included flying hardware, wheels, covers or cases.

These details should be based on the actual unit rather than assumed from the original factory specification.

Frequently Asked Questions

What type of speaker is the Turbosound TSE115?

It is a professional low-frequency/bass enclosure designed to cover the bass and low-mid region of a larger PA system.

What size driver does it use?

The TSE115 uses one 15-inch low-frequency driver with Turbosound’s TurboBass loading system.

What is the TSE115 power handling?

The original specification is 250 W RMS / 500 W program.

What is the impedance?

The original TSE115 is rated at 8 ohms nominal.

What is the frequency response?

Approximately 65 Hz–500 Hz ±3 dB according to Turbosound range documentation.

Is the TSE115 a full-range speaker?

No. It is specifically a low-frequency enclosure and should be integrated with appropriate mid/high equipment for full-range reproduction.
