Efficient bookshelf speakers for my office
Hi everyone,
I'm thinking of putting together a simple office system with the Coincident Dynamo II and a pair of standmount speakers. The Dynamo puts out 8 wpc, so I need a pretty efficient pair of speakers. Only looking for bass down to 45HZ or so. Tower speakers won't work due to the office setup. Will sometimes crank it up a bit, but generally looking at listening at 75db or so. Would welcome any recommendations. Prefer a smoother, warmer speaker to a hyper-detailed one.
Thanks for any advice you can offer.
Best, Scott

I was going to wait to see what people posted because this is not my specific area of expertise. The Joseph Audio speakers are typical sensitivity for audiophile type bookshelves (86db / 2.83V). This means you really need a good amount of power to drive them to any sort of decent volume level (i.e. 50-100 watts). For 8 watt SET tube amps, you really need to look for high efficiency speakers. It depends on your budget and what you want. These are usually horn-loaded speakers or single driver full range speakers. If you have a low budget, maybe try Klipsch Reference RP-160M bookshelves, which have a sensitivity of 96db: http://www.klipsch.com/products/reference-premiere-bookshelf-speakers?model=rp-160m Here are a few other options: http://www.zuaudio.com/loudspeakers/ http://www.lowtherspeakers.com/lowther.html https://omegaloudspeakers.com/collections/monitor-speakers Lot’s of choices. I’m sure others have better recommendations. Some speakers can have efficiency up to 101db. |

How efficient? I just posted a free design for a 91 dB single driver which can fit in a very small space. https://speakermakersjourney.blogspot.com/2017/08/introducing-lm-1s.html I should mention, the design is free, I'm not making money except to get people interested in DIY. Best, E |
@auxinput - as you undoubtedly know, sensitivity is only part of the equation. The JA RM7s impedance does not dip below 6 ohms at any frequency and has relatively benign phase angles so may work fine with lower powered tube designs depending on the amp, your room, listening volume, etc. If the RM7s look interesting to you I'd call Coincident to see what they say as they'd know better than anyone what speakers would be suitable for their amp. Best of luck in your search. |
