A range is not a product list
A speaker cable range usually starts as a sensible list and then grows by accident. A customer asks for a thinner conductor, so a line is added. Another asks for a different jacket colour, and a second line appears beside it. A year later the catalogue holds forty lines, half of them slow-moving, and nobody on the buying team can explain why any specific one exists.
Distributors who avoid that outcome treat the range as a set of axes rather than a list of products. Every catalogue line becomes a deliberate point on those axes, and every point has to be justified by a buyer segment it actually serves. The question is never “can we add it?” — a factory can almost always make it — but “which buyer is blocked if we don’t?”
The four axes of variation
Almost every speaker cable line is defined by four independent choices:
- Construction family — how the conductors are arranged and insulated.
- Conductor cross-section — the conductor area in mm², which sets current capacity and how much signal is lost over distance.
- Jacket — colour, printing and finish, which carries the brand and the identification.
- Length and packaging — the format the cable arrives in, which decides how your customer actually handles it.
A healthy range is not the full cross-product of all four. It is a spine of lines that cover the construction families you sell, each available in the cross-sections that matter for your market, offered in the jacket and packaging formats your customers reorder most often.
Start from the construction families
Speaker cable is not one product made in different sizes. The construction decides where the cable can be used, and that is what a distributor is really buying. The full published LBS range is laid out on the professional speaker cable category page; the four families below are how it divides up.
LBSRVH tour-grade is the reinforced construction: 4N OFC conductors, cotton thread and paper filling, and a PVC jacket, from 2 × 1.5 mm² to 2 × 6.0 mm² with an outer diameter of 8.3–12.5 mm. The filler keeps the two conductors separated and holds the round profile, which is what a cable that is coiled and uncoiled many times needs.
LBSRVS is the jacketed construction for fixed installation, 2 × 1.5 mm² up to 8 × 4.0 mm², with an outer diameter of 8.3–16.5 mm. The multi-core sizes exist because permanent installs often want several channels in one jacket instead of several separate reels.
LBSRVB-P is the two-colour parallel construction, 2 × 0.75 mm² to 2 × 2.5 mm². The flat parallel profile is the format installers expect for quick polarity identification and short runs behind equipment.
LBSRVB Hi-Fi transparent is the transparent-jacket construction at 2 × 100 to 2 × 500 strands — the construction a Hi-Fi retail channel reaches for when the cable is meant to be visible.
Four families, four different buyers. A range that carries only one of them is only serving one of them.
Build the cross-section ladder, not the whole staircase
The most common mistake is offering every conductor size. It doubles the SKU count, splits your stock across lines that each move slowly, and confuses the customer at the point of ordering.
A better approach is to define a floor and a ladder. Set the smallest conductor your market realistically buys, then step up in meaningfully different sizes, and stop at the largest size that is actually requested. The step between two adjacent lines should be large enough that a customer choosing between them is making a real decision, not a rounding decision.
Which sizes sit on the ladder depends on the application, not on the catalogue. Amplifier output and run length set the minimum; the installation environment sets the ceiling. If you need the selection logic itself, it is covered separately in the speaker cable gauge guide.
The reinforced tour-grade range is a worked example of the ladder: 21 published models across 2, 4, 6 and 8 conductors and six cross-sections, including the intermediate steps a distributor usually skips — 2 × 2.0 mm² (15 AWG) and 2 × 3.0 mm² (13 AWG) — with the multi-circuit 8 × 4.0 mm² (12 AWG) at the top. Each page carries its own published conductor count, cross-section and jacket O.D., so a stock list can quote real model codes instead of size descriptions.
What to leave out
Three things look attractive in a range and usually are not:
- Redundant steps. Two adjacent conductor sizes both selling weakly means one of them should go.
- Colour as a stock line. Jacket colour is a real ordering axis, but a colour variant of a slow line is not a new line — it is an option on an existing one.
- Formats you cannot support. Every packaging format you add is a handling commitment, not just a catalogue entry. Carry the formats your customers reorder, not every format the factory can produce. The roll lengths and packaging guide covers what that decision involves.
The test is simple: for each proposed line, name the buyer segment that is blocked without it. If you cannot name one, the line belongs in a special-order list rather than in the core range.
Briefing the factory on a range
Once the spine is defined, the factory briefing is short and precise. For each line, give the construction family, the conductor cross-section, the jacket colour and any printing text, and the target length and packaging format. Add the target market, because it can affect how the specification is written up.
A range briefed this way is comparable line by line, which is what makes it possible to hold the specification stable from one order to the next — the thing that matters most once your customers start reordering. The reverse case, a single-line brief that arrives one enquiry at a time, is handled on the OEM cable manufacturer page.
The result a distributor actually wants
A range built this way is smaller than an accidental one, and it is defensible. Each line has a construction the buyer understands, a conductor size that matches an application, a jacket identity that can carry your brand, and a packaging format your customers already handle. When a customer asks why a line exists, there is an answer. When a customer asks for something not stocked, there is a clear path to a special order instead of a gap.
Where this connects to the rest of a catalogue
A speaker cable spine rarely stands alone. Distributors who supply audio projects usually pair it with the connectors that terminate it — the Speakon, XLR, RCA and TRS connector range — and with the speaker cable range itself as the reference for construction differences. Where the range has to suit a particular buyer, the bulk speaker cable wholesale page sets out how the supply conversation works, and the installer cable page covers the fixed-installation view.
Next step
If you are building or trimming a speaker cable range and want a line list checked against what can actually be produced, send the brief through the enquiry form — construction family, conductor cross-section, jacket and packaging per line.
Related: the same SKU logic applies to the jacketed range. LBSRVS-4X4.0 — two loudspeaker circuits is the 4-core member of a 21-model range that repeats one 4.0 mm² (12 AWG) conductor across 2, 4, 6 and 8 conductor constructions, so a distributor can hold one conductor section in four core counts instead of four unrelated cables.
