Here are some measurements of a Biltema 84-1511 Bluetooth speaker.
The current price in Sweden is 129 SEK (~12.9 USD).
Biltema is like a Swedish mix of Harbor Freight and Canadian Tire, but they only sell products with their own brand name.
The 5m (~16.4 ft) 3.5mm cable used was 59.90 SEK (~5.99 USD), well above the recommended 10%, and of course it's from Biltema as well, for perfect synergy. I didn't have time to do any cable burn-in though, but it should only affect the subjective performance, since it's not measurable.
To make sure that I was only using clean power during the measurements, both the speaker and my Macbook Pro were running on battery - no chargers connected.
I had to put the speaker on a glass to reduce reflections from the stand, but don't worry. The glass is transparent.
CTA-2034 data:
The 1.6 inch woofer drops off below 400 Hz.
Sound power, early reflections and directivity index are all interesting, most likely because of the up-firing driver.
Vertical 0-deg axis is with the driver at a 90 degree angle, to get the same "on-axis" response as the horizontal 0 deg.
Early reflections:
The very bright ceiling bounce is expected with the up-firing driver. Maybe you could use this speaker for Dolby Atmos?
Estimated in-room response:
Horizontal directivity:
Vertical directivity:
Near-field:
The woofer was distorting (audibly) quite a bit at 72 dB SPL / 1m (82.5 dB @ 30 cm), so I didn't measure at higher SPL.
Obviously bad below 300 Hz, but surprisingly low distortion > 500 Hz.
Listening test:
I started by listening to Eiffel 65 - Blue:
Imagine a large, open and detailed sound, with all veils lifted. It's like you were there at the recording session. Both micro- and macro-dynamics are impressive for a speaker of this size.
I then listened to a number of reference tracks, and I have to say that this little speaker is quite impressive. It needs a subwoofer (or well, a woofer) but imaging is excellent and overall tonality is quite neutral.
Well, that would be very impressive, if it was true.
(The measurements are real though)
