This is a practical buyer note on the L-Acoustics SB28: what to inspect, which specs matter for rental work, and where a used unit should price for a B2B order.
Specs that actually matter
For rental and integration work, confirm the key operating spec on the L-Acoustics SB28 against the manufacturer card, and ask for a powered test rather than a bench photo alone.
Tested used stock is the fastest way to add capable Subwoofers to an inventory without waiting on a factory lead time. The risk is in the condition story: a clear grade, a powered signal test, and documented hours remove most of it. That is why buyers keep coming back to tested lots rather than gambling on unverified units.
What to check before buying
Ask for: a powered signal test, the hours or mileage where known, the included accessories, the country of dispatch, and a written grade. On the L-Acoustics SB28, pay particular attention to connectors, fans, and channel or driver consistency.
Shipping and lead time
For a B2B order, expect a proforma invoice, per-lot pricing, and freight to your region. Typical export paperwork covers the CIS, Middle East, South America, and Africa; lead times depend on the destination port and lot size, and the minimum order is quoted per lot.
Next step
Send the model and target quantity to our trade desk. We will come back with an exact price, freight to your region, and the minimum order for the lot.
