Here are some measurements of the Dynavoice Definition DC-5 center speaker.
The MSRP is ~225 USD (2490 SEK), and it's still available new.
Dynavoice is a brand from Winn Scandinavia, the company behind JWS, Proson, Genexxa, System One and others through the years.
I've tested two other speakers from them, but one was quite old, and the other one was very inexpensive. This one from their current top series, and matches the DM-6 bookshelf, and the DF-8 floorstander.
Specs:
Power handling (RMS): 125 W
Power handling (Max): 180 W
Woofers: 2 x 5.25 inch
Tweeters: Ribbon + soft dome
Frequency response: 36 - 32000 Hz
Sensitivity: 92 dB
Crossover: 1800 / 9000 Hz
Nominal impedance: 8 ohms
Dimensions (BHD): 500 x 185 x 300 mm (19.69 x 7.28 x 11.8 inches)
Weight: 9.8 kg (21.6 lbs)
It has a crossover adjustment jumper at the back. Default setting (0 dB) is with jumper in the right position.
I ended up using +2 dB since it gave the flattest on-axis response. Measurement axis was between the two tweeters (center of the cabinet).
Here's the difference between the settings (normalized to + 2dB):
My measurements are quasi-anechoic, with nearfield ports+woofers, corrected for baffle edge diffraction, merged with gated measurements at 1m distance. I also did a sweep at 2m, and the response was identical. I forgot to save it though.
I couldn't find any other measurement, but the Swedish magazine Hifi & Musik reviewed the matching DM-6 bookshelf speaker back in 2009 (same drivers). Here's a comparison (their measurement is gated):

Quite similar. Treble difference is caused by measurement axis. They most likely measured at the ribbon tweeter (I would do that as well with a bookshelf speaker, but with a center, the middle of the baffle makes more sense, and it also gave the flattest response). No information on recommended listening axis is provided by the manufacturer.
CTA-2034:
Early reflections:
The CTA-2034 graphs look surprisingly good, but the early reflections are quite messy (MTM design, and it looks like the two tweeters are causing some cancellation as well).
Quasi-anechoic response:
Estimated in-room:
It looks like the +2 dB setting, while good for on-axis response, is a bit too bright in-room.
This is probably not accurate (I just applied the normalized difference between two on-axis measurements), but it might give a clue as to how it would sound with the 0 dB setting:
Horizontal directivity:
0-90 deg:
Vertical directivity:
0-90 deg:
As expected with MTM, the horizontal directivity is not great. Vertical is better, except for the treble.
Near-field:
Port resonances are quite low, and driver integration looks good, except for the two tweeters. They're overlapping, and it's probably what's causing the messy vertical off-axis response > 5 kHz (cancellation).
Distortion:
Low distortion > 100 Hz. The woofers were moving quite a bit though, so I didn't measure att higher SPL. No audible port noise.
Here's a comparison between my quasi-anechoic measurement and actual response at 1m distance (the same measurement but without gating, and with smoothing applied instead).
The overall response is very similar down to around 150 Hz, where it drops of in-room. That's not a fault with the near-field measurement though. It's just because of the rear-mounted ports, and the speaker being in the middle of my garage (the quasi-anechoic response is more accurate).
I listened to the speaker while writing this, and it actually sounds more than acceptable considering how inexpensive it is. It's a bit bright though, probably because of the lack of bass (-12 dB at 50 Hz). There's also some "tubbiness" in the upper bass, and at times the midrange can sound a bit "resonant" for lack of a better word.
The sound changes when moving from left to right, but it doesn't turn into a "muffled mess" like with some other MTM designs.
I still have the Bowers & Wilkins 686 S2 that I measured a while ago, so I thought a comparison would be interesting. I didn't expect the B&W to sound worse though. I mean in some ways it's better. The slight "tubbiness" is gone, but the midrange in the B&W is very hollow/dull and the treble is annoying.
Anyway, the Dynavoice DC-5 is much better than other speakers I've heard from this manufacturer through the years.
