Pro-Ject Xtension / 12cc Evolution (Black; item 67094) review

This document-led reference assesses Acoustic Sounds item 67094, not an individual unit. The Black Xtension listing names a 12ccEvo tonearm but leaves cartridge inclusion unresolved and contradicts itself on total mass. It stays out of shopping matches while the verifiable deck facts are documented.

Resolve the revision before comparing specifications

The retailer calls this “Xtension Turntable w/ 12ccEvo Tonearm,” labels it Black Finish and assigns the seller-side Product No. T XTENSION 12 BL. The exact-item page is the strongest source for what that retailer calls its product; the code is not presented as a Pro-Ject manufacturer part number. The older Pro-Ject Xtension product sheet, revision 1.4.10, names a manual Xtension with the Pro-Ject 12cc Evolution arm and lists Black gloss as a finish. Its 5.7 kg platter figure also matches the Acoustic Sounds specification table.

That match matters because the current Pro-Ject Xtension 12 Evolution sheet is not a safe substitute. The manufacturer’s May 2025 sheet lists a 10 kg platter and a 30 kg net deck, while the older seller item and revision 1.4.10 sheet describe the 5.7 kg platter version. Treat the older item as an earlier documented configuration, not as the 2025 specification with a different finish. Do not carry over modern product-page figures just because the family names overlap.

Mass is a real unresolved conflict, not a rounding detail

The Acoustic Sounds page has two total-mass statements: its technical table says 20 kg, while the descriptive paragraph says 25 kg. The old manufacturer sheet confirms the platter revision but gives no total mass. The newer 30 kg figure belongs to the changed 10 kg-platter configuration and cannot reconcile the old seller page. Verify the revision and a reliable mass for the exact unit before placing it on a shelf or moving it.

The platter number is better supported: both the exact retailer specification and the legacy manufacturer sheet state 5.7 kg for the older version. That is the platter alone, not the weight of the whole turntable. It is a substantial part to lift and fit during setup, so plan a stable work surface and follow the model-specific handling instructions rather than treating this as a lightweight plug-and-play deck.

Manual speed changes and setup take attention

The revision 1.4.10 sheet describes belt drive, electronic selection between 33 and 45 rpm, and a manual belt change for 78 rpm. That gives the deck three documented speeds, but 78 is not selected by the same quick control used for 33/45. The unit needs correct belt placement and leveling; Pro-Ject’s instructions for the related 12cc Evolution arm show user setup for downforce, anti-skating and alignment. This is a manual turntable, not a fully automatic machine. I found no exact-item document that establishes an end-of-record auto-stop, arm lift or return, so treat those behaviors as unknown rather than silently assuming either answer.

The older sheet lists a 12cc Evolution 12-inch arm, a single-piece carbon-fiber headshell and armtube, adjustable arm height and azimuth, and a 123 cm Connect it 5P-C interconnect. The retailer likewise describes a 12-inch carbon-fiber Evolution arm and cable. These details help identify the deck and explain the setup attention it expects; they do not identify the pickup in the seller's package.

The cartridge and phono route need exact confirmation

Neither the exact Acoustic Sounds item page nor its photograph tells me whether a cartridge is included. The title names a tonearm, not a cartridge, and the image cannot prove what is installed or supplied. The manufacturer’s older material describes tonearm compatibility and cartridge adjustment, but it does not establish the box contents of this retailer item. Ask for a written, item-specific answer about cartridge make and model, whether it is fitted, and what the box includes. Until that is known, there is no responsible way to label this package MM or MC, select a matching PHONO input, or claim that the required phono-stage route is settled. A cable with RCA plugs is not itself a phono preamplifier.

Acoustic Sounds lists a dust cover and record weight for the item, while the legacy manufacturer sheet lists an interconnect and external supply. Those are page-level product details, not an independent check of a particular carton. Confirm the exact cover, clamp, cable and supply contents, and verify the supply's voltage label.

Measure the body and leave room to work

The older product sheet lists 550 × 250 × 450 mm (21.65 × 9.84 × 17.72 inches) with the cover closed and 550 × 550 × 560 mm open. These are body dimensions in width × height × depth order, not a guaranteed operating envelope. Allow extra space to raise the cover, lift and move the arm, reach the controls, route the phono cable and handle records. The large open-cover footprint is particularly easy to miss if a shelf is sized only to the closed dimensions.

Why this remains a reference, not a recommendation

The deck-and-arm identity is documented, but cartridge inclusion remains unreported and seller total mass remains inconsistent. A probable package is not promoted to fact, and no Amazon mapping is made. Confirm the cartridge, mass and box contents for exact item 67094 before treating it as a complete system purchase; until then this is a technical reference.

Sources and limits

The Acoustic Sounds item 67094 supports the seller title, finish, 12ccEvo arm, listed platter and the conflicting mass statements. The older Xtension / 12cc Evolution product sheet supports the 5.7 kg platter, manual speeds, arm details and body dimensions. Pro-Ject’s 2025 Xtension 12 Evolution sheet is cited only to distinguish the newer 10 kg-platter, 30 kg version; those specifications are not transferred to item 67094. The item-specific image shows appearance only. No price, present supply, sound quality, measurement by the author, ownership or hands-on use is claimed.
