What would the power amplification need to be (output in watts - single channel) to power (5) FreeSpace 3 Series II bass modules - 70V tapped at 200W, with 4 satellite speakers each, hung by an omni mount kit?
Hello need your help A friend gave me 12 Freespace model 16 speakers that were taken from a car dealer after remodeling the space. I don´t know what to do with them, but I was thinking to take 5 or 7 and make a home cinema room with my HD Projector. At the moment the projector is conected to a sound bar, but I thought to make it more cinema type of room, by using this Speakers. 1st is it possible to use this speakers to create a 5.1 or 7.1 system? If yes, are they any good, in terms of sound...
Hello, The 2nd part of the ongoing FreeSpace recall targets speakers mounted in volumes of air containing cooking oil fumes. Is this notice relevant for deep fry oils only, or does it also include i.e. steam/fumes from waffle irons, pan cooked bacon, bain-maries etc.?
Hello, When setting a single freespace 3 surface bass module, the watts required state: 70/100 V: 200 W (800 W peak) mono Low impedance: 100 W (400 W peak) mono does that means you get more dB from it on a 70/100 installation? also how does having a pair or two pairs of satellite installed on said bass affect the power consumption and dB output?
I have three rooms which will require a ceiling speaker (e.g. FreeSpace DS 40F) and a wall volume controller (e.g. ControlCenter CC-1 zone controller) in each room. Will I be able to use one FreeSpace IZA 2120-HZ amplifier in this setup? Or are there any other recommendations that will allow three rooms to have a speaker and volume controller in each? Thanks in advance, Andrew.
Hello Luis, 1) No, you do not get more dB from 70/100V system, they are equal. It has to do with the way transformers are wound, the outcome is roughly the same. 2) Actually, a system with 4 cubes has potentially 3dB less output above 200 Hz when using the cubes in series, however, the systems have been calibrated by Bose to have a good tonal mix using 4-cubes. Using 4-cubes has the benefit of covering more of the room, and is the most popular method of installation. BR Arno
Dear Peter, This concerns commercial cooking environments where cooking oils are used. So this excludes bain-maries, but includes cooking bacon. I will reach out to you at the Bravo Audiovisual email address I know. Thank you. Rik
The IZA2120-HZ is a 2 zone amplifier. If 3 zones are required a second IZA2120 / ZA 2120HZ or IZA / ZA 190-HZ (depending on the required power) is required. Or you can used 100V attenuators instead of the CC-1 as long as you do not need to change input source per zone. You can also have a look at our 4 channel amplifiers like the PowerShare and our new PowerSpace line. BR Arno
Hi Andre, It's technically possible to use them for home theater, but I don't usually recommend it. They have low impedance terminals, so you don't need a commercial 70v/100v amp, but you'd lack speaker EQ, and they're rated for only 16W each. An average home theater receiver might be designed for 50-100W outputs per channel (4-8 ohm). They work well for distributed audio systems, and background music. If you'd like to learn more about what we use them for, please visit pro.bose.com. Thank...
