Bose Spatial Control Receiver

 

Bose Spatial Control Receiver

 

Well, Bose may not be known for their receivers but this is one nice looking stereo! This is the Bose Spatial Control Receiver which doesn't seem to have a model number on it but I believe it is considered model 551. It puts out 100 watts per channel and has a built in EQ for the Bose 901 series IV speakers. Bose also made a model 550 that had a built in EQ as well but only sported 40 watts per channel and had no spatial control.

Here you can see the slider knobs used to control the EQ for the speakers. The front of the receiver has a flip down panel to access the controls.  Also, the power switch is on the back of the unit and when it is on you can still turn the unit on and off by touching the Bose logo on the front of the unit.

These Bose receivers aren't that common and it's probably due to the fact that not that many were sold. The sales copy explanation behind how the "spatial" effect worked was somewhat complicated and, of course, they were really designed to work with the Bose 901 speakers (though they could work with any speakers). So, may customers probably opted for a more simple solution to their audio needs. Nonetheless, these receivers do sell for decent amounts of money. In fact, if you're a Bose fan then one of these units is probably a necessity.  I've seen fairly average condition Bose 551's sell for over $300.00 and one in very good condition sold for around $500.00.

Hello, I just came in possession of a 551 Bose Spatial Receiver. And I believe the previous owner told me years ago that he left channel was flakey and had went bad some time back. His wife and mine work together, and she just gave the my wife to give to me. I was wondering if anyone knew where I could get hold of a schematic or a service manual for it?

I bought a manual from these guys sometime back: http://www.analogalley.com/osccart/product_info.php/products_id/42

Maybe you can contact them and check. Mine didn’t have any markings and the manual turned out to be correct.

I’d hopefully like to add a small correction/clarification. I’ve written quite a bit about this fine receiver (and own several of them) and would like to point out the unit is the “Bose Spatial Control Receiver Model 108787″. The Model 108787 definitely had an original version (considered a Series 1 though not marked so) and then also a “Series 2″ later produced and quite possibly a Series 3 (though I’ve only seen one single photo of one).

Cheers,
Lee of NJ

Thanks Lee! I appreciate the information. I’ve never seen one of these “live” but it sure is a fine looking receiver. You don’t hear much about Bose receivers as it seems their speakers hog all the publicity.

I had the privilege of enjoying the 551 Spatial Control Receiver and a set of 901s that my best friend bought in the early 80s. I’ve inherited the receiver and just found a pair of 901s with blown out surrounds on the drivers. Anxious to get it running again and enjoy the crisp sound that the system used to produce. If you haven’t had the pleasure, take the opportunity if it comes. I haven’t heard a better system.

I haven’t heard the 551 receiver but I have heard the 901’s. It’s quite a job to refoam all those drivers but can definitely be done with some patience. I’ve seen the foam kits on eBay for about $40 and people that will refoam them for you for about $200.

hey lee and all , i took my scr all apart and throroughly cleaned and lubed it. time consuming but not difficult. i took 11 internal pics. i found two things that i can also do to help it a little more. however the two shops in mpls. will not touch it and don’t want to talk about it anymore.although i got two helpful tips from one tech. he knows ALL about it but does not want to share.(too busy). he mentioned there are about 50,000 eletrolytic compacitors that all need replaced. great. i’m running it now with 501’s and HK-CDR 20 i like it.sure wish i could afford some nice series-4,901’s.hek i’d refoam and rewire old ones. let me know if you all want pics. gypsy
