DESCRIPTION

The R.25-94Z is a 2-way, full-range loudspeaker system designed to provide high quality voice and music reproduction in applications requiring extreme weather resistance. It is designed to withstand long-term exposure to tough, environmental conditions and to provide performance normally associated only with indoor loudspeakers. Both the R.25-94Z and R.25-94TZ have an 8-inch (203mm) cone LF driver and a ¾-inch (20 mm) exit HF compression driver with weather resistant diaphragms. The HF driver is coupled to a nominal 90° x 40° horn. The HF assembly is coaxially mounted with the LF driver. The R.25-94TZ has a built-in multi-tap 200W autoformer for 70V /100V operation and a rotary switch for tap selection. The R.25-94Z’s high efficiency, modest power requirements and 8 Ohm impedance makes it easy to deploy large numbers of loudspeakers using only one amplifier, keeping the overall system costs to a minimum. The large 200W autoformer in the R.25-94TZ allows the loudspeaker to maintain its full high output capability even when running on 70V/100V systems. Both models carry a 5 year product warranty and a 15 year enclosure warranty.

NOTES

PERFORMANCE SPECIFICATIONS All measurements are taken indoor using a timewindowed and processed signal to eliminate room effects, approximating an anechoic environment, a distance of 6.0 m. All acoustic specificationsare rounded to the nearest whole number. An external DSP with settings provided by Biamp is required to achieve the specified performance; further performance gains can be realized using the FIR loudspeaker optimization presets available in Biamp’s Community Loudspeaker Controllers (ALC Series).

OPERATING RANGE The frequency range in which the on-axis processed response remains within 10dB of the average SPL.
CONTINUOUS POWER HANDLING Maximum continuous input voltage (and the equivalent power rating, in watts, at the stated nominal impedance) that the system can withstand, without damage, for a period of 2 hours using an EIA-426-B defined spectrum; with recommended signal processing and protection filters.

NOMINAL SENSITIVITY Averaged SPL over the operating range with an input voltage that would produce 1 Watt at the nominal impedance and the averaged SPL over the operating range with a fixed input voltage of 2.83V, respectively; swept sine wave axial measurements with no external processing applied in whole space, except where indicated.
NOMINAL MAXIMUM SPL Calculated based on nominal/peak power handling, respectively, and nominal sensitivity; exclusive of power compression.

EQUALIZED SENSITIVITY The respective SPL levels produced when an EIA-426-B signal is applied to the equalized loudspeaker system at a level which produces a total power of 1 Watt, in sum, to the loudspeaker subsections and also at a level which produces a total voltage, in sum, of 2.83V to the loudspeaker subsections, respectively; each referenced to a distance of 1 meter.
EQUALIZED MAXIMUM SPL The SPL produced when an EIA-426-B signal is applied to the equalized loudspeaker system, at a level which drives at least one subsection to its rated continuous input voltage limit, referenced to a distance of 1 meter. The peak SPL represents the 2:1 (6dB) crest factor of the EIA-426-B test signal.

AXIAL PROCESSED RESPONSE The on-axis variation in acoustic output level with frequency of the complete loudspeaker system with recommended signal processing applied. 1/6 octave Gaussian smoothing applied.
AXIAL SENSITIVITY The on-axis variation in acoustic output level with frequency for a 1 Watt swept sine wave, referenced to 1 meter with no signal processing. 1/6 octave Gaussian smoothing applied.

HORIZONTAL / VERTICAL OFF-AXIS RESPONSES The loudspeaker’s magnitude response at various angles off-axis, with recommended signal processing applied in the operating mode which utilizes the largest number of individually amplified pass bands. 1/6 octave Gaussian smoothing applied.
DIRECTIVITY INDEX The ratio of the on-axis SPL squared to the mean squared SPL at the samedistance for all points within the measurement sphere for each given frequency; expressed in dB.1/6 octave Gaussian smoothing applied.

BEAMWIDTH The angle between the -6dB points in the polar response of the loudspeaker when driven in the operating mode which utilizes the largest number of individually amplified pass bands. 1/6 octave Gaussian smoothing applied. Data presented on this spec sheet represents a selection of the basic performance specifications for the R.15COAX. These specifications are intended to allow the user to perform a fair, straightforward evaluation and comparison with other loudspeaker spec sheets.

FAQS

What are the two main functions of a speaker?

The speaker’s official role is to moderate debate, make rulings on procedure, announce the results of votes, and the like. The speaker decides who may speak and has the powers to discipline members who break the procedures of the chamber or house.

What makes a good public speaker?

Great speakers do not use waster words and only use words that add value to their message. The speak at a slower pace and pause to eliminate non-words, or filler words, like “um” and “so”. They are also mindful of to reduce redundancies. Great speakers and leaders know how to be clear and concise.

Are community loudspeakers good?

Community Loudspeakers are outstanding for applications such as indoor-outdoor public areas, sporting venues, stadiums, transportation hubs, arenas, parking lots, airports, malls, rail terminal stations, public buildings, parks, recreational areas, and more.

Why are Speakers important in an event?

A guest speaker can perform a number of different roles. They can energise a crowd, inspire them, support the event themes, add value by sharing insider knowledge, offer a new perspective, break up the more routine aspects of the event and entertain.

will this fit in 1966 mustang rear window?

Yes they will fix and they sound good

Are they for the rear or does it matter?

It shouldn’t matter if they are the same as your speakers they will fit. I got them for the rear roof of a 99 Tahoe

What is the dimension of grills and speakers?

4 in deep by 4 in across and 6 in wide

What is speaker communication?

Speech communication refers to the use of the oral medium of passing information, whether formally or informally, by a speaker to an audience.

What is the hardest part about public speaking?

The beginning is the hardest part when it comes to giving presentations. Having the full first minute of your presentation committed to memory will help you at the most critical moment.

What are public speaking challenges?

Failing to relate the material to the audience, maintaining eye contact and reading their expressions can negatively affect how your speech will be interpreted. Explaining how the material benefits listeners personally and using anecdotes attracts the audience’s attention.

What are the skills of speaking?

A skilled speaker can use the sub-skills of pronunciation to emphasize and make the communicative effect of their speech more impactful. The sub skills of pronunciation include word and sentence stress, intonation, rhythm and the use of the individual sounds of a language.

What causes loss of speaking?

Aphasia usually happens suddenly after a stroke or a head injury. But it can also come on gradually from a slow-growing brain tumor or a disease that causes progressive, permanent damage (degenerative). The severity of aphasia depends on a number of things, including the cause and the extent of the brain damage
