Eminence Tonker Vintage Guitar Speaker (150 Watts, 12")

Eminence Tonker Vintage Guitar Speaker (150 Watts, 12"), 8 Ohms, Side

This speaker provides that desirable British tone, but it's perfect for any genre. It's available in 8 ohms or 16 ohms.

Overview

Direct from the Eminence Red Coat series arrives the Tonker. The Tonker is a hard hitting 12 in. speaker that provides that British flavor players crave for but the harmonic balance to properly tackle any genre. This speaker excels in English, Southern and Country rock genres for that reason. If you own a Telecaster your tone will thank you for using the Tonker.

When Eminence was asked to create a speaker with a very fat clean sound in the mid-range but still a very smooth top end they created the Tonker. Available in 16 and 8 ohms versions.

Important Note

Watts: The guaranteed long term power rating throughout the usable frequency range of the speaker.

(Translation: the speaker will operate continuously at any frequency within the speakers specified frequency range when driven at this power. The "Watts" rating is similar to RMS, but is really more indicative of long term thermal capability.)

Music Program: The speaker will safely and reliably handle the varying frequencies of musical content at this power rating. The "Music Program" rating is more indicative of what you can expect in the real world with the speaker operating within the appropriate enclosure reproducing music or vocal audio program.
