Hi

I checked in the specs of the manual here. page 6. They quote it as being suitable for 4-8 ohm AMPLIFIERS. but do not mention the actual impedance. I would expect from that that the speakers must be close to 8 ohms, as you they would not advise you to connect a 4 ohm speaker to an 8 ohm output stage, as likely damage could result. If you had a multi meter, you could do a DC resistance check of the speaker, this is generally very close to the impedance. happy to talk to you more about it.

    I turned in the two 151 SE speakers because my ohm check had open circuits for both but these new ones are just the same. Using the volt meter I get just the same readings on these and when I connect up the speaker to the output per the spec I only can get clicking when changing the volumn. No sound just clicking.

I have a TOA 301 15W amp and a Bose 151 environmental speaker(40w 4 ohms). I do not have a manual for the amp and wish to connect the speaker as a small PA . My concern is that the output I think I should...


Don't worry about the 7.7 volts. Just connect between COM and 4 ohms and you'll be fine. I didn't find a 301 part number related to a 15w amplifier, but I did find a BG series (115 130) of 15 watt amps manual http://www.toa-products.com/international/download/manual/bg115_mt1e.pdf

Which amplifier that match 2 of JBL CM52 speaker and 2 of Bose 151


If you want to run both the speakers at a time you will have to buy a professional amplifier like CROWN XLS202.
Because together the total impedance will drop below 3 Ohms. An average domestic amplifier is designed to run speakers between 4 to 8 Ohms.
If you are running only one pair at a time you can buy any of the following Amplifiers.
Marantz - PM 7003
NAD C356

Not sure of how to wire these speakers ( internal ) Bose 901 series iv


Found on Google Search: "bose 901 internal wiring" You must first identify which series you have. The first two series were acoustic suspension, and used nine 8 ohm drivers in a series/paralel configuration. Series III through VI used nine .9 ohm drivers all wired in series. Series III and IV had an additional terminal for use only with the Bose Spacial Control Receiver. Series III through VI are easy to identify, as there are three ports sticking out the back of each enclose. The 1st two series have no ports.

Inpedance button ???


The impedance button allows you to toggle between 4 and 8 ohm speakers. By default, most receivers are designed to run an 8 ohm load as this is the most common draw from home speakers. However, a few may exist that require a 4 ohm demand (many Bose for example). Or, if you have two 8 ohm speakers connected to a single speaker terminal, the impedance will drop to 4 ohms for that channel. In your case, you most likely have a regular pair of speakers with an 8 ohm impedance. In this case, the button out (8 ohm) will do the trick.

Bose 151 main with amp


Does your tv have stereo outputs? if yes all you have to do is run RCA red..white jacks into tv outtput then run the other ends into the amps tape or aux or cd input and your done! If you dont have outputs on tour tv you will have to but an RF converter box (about 20.00 at wal-mart) and hook that into the tv and the cables will run out of that to the stereo!

Changing out my monitor speakers to bose cube speakers


You probably can do it as long as the speakers there now are 8 ohm speakers and you must use the bose bass module with the cubes because the crossover is built into the bass module for the cubes to work. If you just wire up the cubes you will mess the cubes up and they want sound right at all. The cubes are no good without their bass module in other words. Hope this helps.

Do all speakers have fuses? I may have blown one of my Bose 151 outdoor speakers, but can't find a fuse inside.


Unfortunately many speakers do not have fuses. Most likely the voice coil has opened up inside the speaker itself. You can either get a replacement driver (speaker) or re-cone the one you have. In any case, the driver needs to be replaced.

You can verify this if you use an ohmmeter. With an 8 ohm impedence speaker, the reading should be about 6 ohms. If you read a higher number or infinity, the coil is bad.
