I know, this is going to sound ridiculous. Before I start, I want to say I have a dedicated theater room with JBL M2's and SCL-4 surrounds, Crown I-tech and DCi network amps etc, all good stuff.
I have a Bose Soundbar 700 with matching sub and surrounds in the living room, just for the purpose of improving on the TV's sound and the universal remote it comes with is really nice. It's as simple as can be and everyone in the house can enjoy it. I have been pleasantly surprised by it since I bought it 3 years ago, and yesterday I decided to take some REW measurements of it, just for fun. The results surprised me.
These were taken at the listening position. The Soundbar comes with a mic you wear on your head like a headset and has a form of room correction to use with it. The room correction was run prior to these measurements.
Here is the subwoofer measurement (Red line), with no smoothing applied. I was very surprised to see extension below 30hz. Much better than the old Bose "Acoustimass Modules" that used a pair of 5 1/4" drivers. This sub uses a 10" driver and a 400 watt on board amplifier. If there was some ability to PEQ the sub, I'm confident the response could be made pretty flat with good results.
Here's the full frequency spectrum (green line) with the sub going to the soundbar. 20hz to 20kHz, with the "psychoacoustic" smoothing applied in REW to make it readable. The response is actually surprisingly linear, all the way up to ~16kHz, where it drops off. The target curve appears to be an upward slope as frequency increases, which I found interesting. The measurements I've seen of lifestyle systems from the past were all over the place, with huge peaks and dips, with a huge peak around 7kHz in most cases.
So basically, I see a huge bass boost, and perhaps a crossover delay issue at ~170hz or so? Other than that, I'm surprised to see a mostly linear frequency response and response below 30Hz from a Bose product. Just thought the measurements were interesting and thought I would share.
