Ditonica System 7 – a loudspeaker with a vintage look and an affordable price tag (manufacturer post)

[Ditonica]

Hello everyone. For many years, I've been reading this forum, speaker reviews, new product launches, and admiring what others do. It's time for me to post and present the brand and its product, which I believe may be of interest to some of the readers as well.

About Ditonica

Ditonica is a new name with an experienced team behind it. For over a decade, our Latvia-based factory has been manufacturing loudspeakers and speaker cabinets for various European brands, offering exceptional finish, assembly, and quality control. Following these highest industry standards, we are now offering our own product directly to customers.

By breaking the endless loop of added costs, we can concentrate our efforts on what matters for sound: perfect quality cabinets and parts whose utility can be verified, measured, and heard. The essential part of our sound quality standards is Spinorama measurement.

System 7

The idea behind System 7 is to combine a classic retro look with modern measurement standards: a neutral tonal balance and controlled directivity. Typical obstacles to achieving this goal in this type of loudspeaker are usually diffractions, causing directivity problems around 1000 Hz, and a non-wave-guided tweeter. Both together, they lead to a lack of reflections in the midrange region and excessive reflections around the high-midrange / low tweeter regions, causing directivity errors and colorations of sound in the room.

To prevent these problems, we placed the midrange driver responsible for this region off-center and divided the effect from the left and right edges into different frequencies. After this region, the horizontal directivity tends to become wider, so we use 2500 Hz as the crossover frequency to compensate for it with vertical lobing. And finally, the waveguide effectively reduces the tweeter's directivity after 3000 Hz. This way, we distributed the effects causing directivity narrowing across the wide frequency region, avoiding their concentration.

As a result, a wider midrange dispersion, neutral tonal balance, good level of smoothness for Spinorama curves, and a steady-declining predicted in-room response. Such an interesting combination of characteristics, subjectively, creates a feeling of wider soundstage and more presence in vocals and instruments, especially when moving around in the room.

Cabinet

The cabinet material is 18 and 25 mm MDF. We use internal bracing around the separate midrange volume to make the cabinet acoustically silent, and cotton-wool damping to eliminate the standing waves. The speakers finished with a lacquered natural walnut veneer, adding a pleasant wood texture in comparison to popular vinyl or engineered veneer finishes. The grills are made of acoustically transparent fabric and can create an alternative black-front look.

Instead of large and expensive speaker stands, we equipped System 7 with a compact, angled platform, adding approximately 10 cm of height to the tweeter axis every meter away from the speakers, optimizing the listening position approximately 3 meters away. That aligns the tweeter's axis with the human ear in a sitting position. We include it for all speakers; however, for those who want to try different options, it's easy to unscrew the platform and put the speakers on other stands that customers prefer.

Price and delivery

The starting price per pair is 1990 EUR + shipping to your destination, including local VAT for EU customers. We also accept international shipping; however, import costs may vary depending on your destination. We manufacture speakers based on individual orders, but we plan to maintain a stock in the future.

Measurements

• The reference axis is the tweeter's center
• Tests conducted with grilles off
• 2m distance from the loudspeaker
• Sensitivity adjusted to 2.83V/1m

On-axis response, ground-plane method (the output around 35 Hz is a little bit decreased on the graph due to the rear port).

CTA-2034, quasi-anechoic method (doesn't show the results below 200 Hz due to lack of resolution).

Predicted in-room response.

At this stage, this is a finished product, but we are always open to making improvements. We plan to post future updates, including more detailed measurements and production insights, in the future. I would be happy to answer your questions and receive feedback. Feel free to express your opinion; this is a learning process for us as well.

As a Latvian, I'm glad to see a speaker manufacturer from my homeland following a data and science driven approach. Lai izdodas!

 

[Drengur]

As not a Latvian, I'm glad as well!

Thank you, if you plan to be in Riga anytime, Laipni lūdzam!

Welcome to the forum, I have to say you've got very nice looking directivity given the vintage design. Based on your explanation I finally understand why you see this kind of offset tweeter/ mid... Seems obvious now!

I'm sure these will be popular with Europeans looking for the vintage aesthetic.

Measurements are the base, but listening is fun anyway. Last week, we had an opportunity to listen to our loudspeakers in one of the local audio showrooms. It's always a useful experience to test the speaker's behaviour in different listening environments and feel the variations, especially in the low-frequency range. Currently, we are quite satisfied with the results: the main trend is that the midrange and high frequencies remain neutral and stable thanks to controlled dispersion. While the low-frequency character slightly changes from room to room, meaning that the loudspeakers themselves don't have repeatable tonal deviation.

Do you plan to make any in black or white?

Best of luck with sales too, I’m very partial to good three way speakers and they are a great price.

Ps, I hope you don’t think this rude, but as you asked earlier… have you considered using magnets for grill attachment?

I know the speakers are retro in intent, but holes in the front may be a bit much in 2026…?

Thank you. We're not sure about white, but in the future, we would like to add a Black Oak finish. Below is an example of how this finish looks on other loudspeakers our factory manufactures.

It's totally fine; some people ask this question. Besides the vintage style, the reason we use rubber/plastic fasteners instead of magnets is that we want to create a balance between the complexity of drivers and the cabinet. I like the minimalist design as well, but it only works when the drivers themselves are minimalist. Once the drivers are complex (basket, screws, dust caps), the minimalist cabinet looks off. That's why we add some elements to the cabinet, like a wooden texture, a bottom panel, and grill fasteners.

• Sensitivity (2.83V/1m): 85 dB

Could you elaborate on why the sensitivity seems oddly low? Bass extension is all right for a speaker its size, but not exceptional. And we are dealing with large 75 L speaker, I would expect around 88 dB @2.83V/1m.

Sure, this is a common question. We use an 8 ohm woofer driver with a flat response in its working range and sensitivity of approximately 90 dB on an infinite baffle. A 100 Hz region is a reference point for the total system sensitivity. According to our baffle simulation, we lost approximately 4 dB of the initial driver sensitivity due to the cabinet and baffle step. In addition, the inductor in the low-frequency crossover has some DC resistance. So, when we measure the finished speaker in anechoic conditions, its sensitivity is about 85 dB.

I wouldn't call it "oddly low" for an 8 Ohm loudspeaker, since, unless it's a pro audio driver, it's rare to find a woofer with sensitivity over 90 dB. In fact, most 8 ohm loudspeaker Klippel measurements illustrate a sensitivity of 84-87 dB. Even many of the 4 ohm loudspeakers are in the same range.

There are two videos from Erin on this topic, which help to see the context and the real average numbers:

Fair enough, though I made this remark seeing that Erin measured the Cadentia Three, which has roughly the same volume (75 L), a 9" woofer, a slightly more extended bass response and measured at 86.5 dB/2.83V anechoically.

And the Mofi Sourcepoint 10, which is while a bit bigger (85 L) and had a slightly higher F6 at 45 Hz, but is nominally 8 ohms is 88.2 dB/2.83V sensitive. Maybe it is that I'm more used to seeing measures for 4 ohm speakers.
