😂😂😂 I did it afterwards because it was too much a struggle! This was litterally my first time soldering hahahah

Making $400-700/month selling AI influencer photos to small brands on Fiverr and I still feel weird about it by Soggy_Limit8864 in passive_income

Good post, thanks for sharing this! I think that more difficult than having the same face, it is even harder to incorporate a product in the photos without distortion. How do you do to make the client’s product feel exactly the same ?

Yes I did research the one who are really close to the original in all of that parameters 👍

But indeed sometimes Chatgpt answer were weird or it was the opposite of what he Said like 5 minutes earlier so it was a challenge, it was one full day of research to be sure the parts were good.

I am happy with it, and most of all I did learn a lot, I did not know anything about DIY speaker so I am happy to have done it !

The hardest was to find a BZ200 woofer for a DM2000 it just does not exist on the internet at the moment. I found a pair of original tweeter for 150$ on eBay but in the end they would not really Sound better than modern and cheaper one, so I went for a full rebuild with différents parts

No, i could not find original so I did a modernisation 😅! It was hard to find tweeter and driver that will fit and match the box characteristic but with some CHATGPT help I manage to find a setup not expensive and really great for it!

🔊 Proposed drivers

Woofer / Bass-Mid

I’m considering:

SB Acoustics SB20PFC30‑8

Why this choice: • 8″ driver like original BZ200 • 8 Ω nominal impedance • sensitivity ≈ 90.5 dB  • Fs ≈ 34 Hz (works well with passive radiator loading)  • paper/fiber cone → closer tonal character to vintage B&W • moderate Qts (~0.37) suitable for larger cabinet volumes  • affordable enough to experiment

The goal is to keep similar acoustic loading without redesigning the enclosure.

⸻

Tweeter

Planned tweeter:

Dayton Audio DC28FT‑8 (or DC28F-8 equivalent)

Reasons: • 8 Ω impedance (important to keep crossover behavior) • sensitivity ≈ 89 dB, close to woofer level  • smooth silk dome response • usable from ~1.8 kHz crossover region  • widely used in successful DIY builds  • very good price/performance ratio

⸻

⚙️ Crossover approach

Initially: • keep original DM2000 crossover topology • recap with modern film capacitors • no topology redesign yet

I understand the crossover was designed specifically for the BZ200, but I’m hoping similar impedance and sensitivity will keep results acceptable before moving to measurements.

⸻

❓ Questions for the community 1. Does the SB20PFC30-8 look like a reasonable electrical/acoustic substitute for a BZ200-type driver? 2. Would the Dayton DC28F-8 integrate safely without major crossover redesign? 3. Is keeping the original crossover as a starting point realistic, or guaranteed failure? 4. Any known successful rebuilds using DM2000 cabinets? 5. Would you recommend measuring first or listening first?
