Our take on the Pro-Ject Speed Box S

by Dave Bar
Pro-Ject

Better watch your speed!

If you own a Pro-Ject turntable, this little box is a must-have. First, it lets you change speeds between 33-1/3 and 45 rpm with just the touch of a button — no need to manually move the belt. But what really impressed us is the way it stabilizes the record platter's rotation speed. Even slight speed fluctuations can detract from the magic of vinyl sound, but with the Speed Box S in place, your records will spin with greater speed accuracy and rock-steady consistency. When we plugged it in to one of our Pro-Ject RM 1.3 turntables, we immediately heard tighter, more defined bass. Vocals sounded fuller, with added "body" and presence, lending a greater sense of sonic realism. Pitch accuracy for instruments with long decay times, such as piano, was spot on. Overall, the music seemed to flow just a little easier from a quieter background.

A simple "no install" installation

The Speed Box S makes an easy and cost-effective upgrade. Simply plug it into your turntable's AC jack, then connect it to power with the supplied transformer. That's all it takes to enjoy enhanced performance and convenience.

Highlights:

  • compatible with turntables that use Pro-Ject's 16 Volt AC power supply, including the Debut III & Debut Carbon (except USB models), xPression III, and RM models
  • provides convenient electronic speed change between 33-1/3 and 45 rpm playback
  • quartz-generated high-precision electronic speed regulation
  • small size allows placement near turntable
  • metal case shields circuitry from vibration and electromagnetic interference
  • LED speed indicators
  • microprocessor control of all functions
  • external power supply reduces chance of noise and interference
  • DC cord connects to Pro-Ject turntable
  • weight: 19.75 ounces (without power supply)
  • 4-1/16"W x 1-7/16"H x 5-5/8"D
  • warranty: 2 years
  • Our 60-day money-back guarantee

Pro Ject speed box

Written By Kevin, Seattle, Washington on Tuesday, December 31, 2013
Crutchfield Customer Review (What's this?)
 
Speed box allows speed changes without changing pulley positions on belt drive. Small, well constructed, with nice non-slip feet and easy on the eyes blue indicator lights- unit does what it is designed to do-without excess-very Pro Ject.
Pros:
Solid, minimalist design
Cons:
Leads too short, minimal info literature included

Noticeable improvement.

I received a Debut Carbon and Speed Box at the same time but, tried the Carbon without the Speed Box initially. There was a VERY noticeable reduction in noise after adding this box and records that sounded good, got even better.
Pros:
Noise reduction, convenience, stability
Cons:
Short cable from box to turntable.

Nice add-on

Written By Darryl, Wichita on Tuesday, October 29, 2013
Crutchfield Customer Review (What's this?)
 
The Perfect add-on to the Pro-Ject Debut Carbon, No more taking off the platter to change the speed from 33 to 45 and it seems its more stable. The instructions were sort of lame and a little confusing. but all you need to know is to always start it at 33, then turn it up to 45 when it is at full speed. So just return to to 33 before shutting it down(and you will start at 33 again).

Great upgrade

Written By vicolindo, Raleigh, NC on Monday, July 22, 2013
Crutchfield Customer Review (What's this?)
 
This speed box was a definite upgrade for my Pro-Ject Debut Carbon turntable. Instead of relying on the built in DC motor, this speed box electronically stabilizes the platter speed to 33 1/3 or 45 rpm and you don't have to lift platter off and manually change speeds by moving belt on pulley. There's a definite upgrade to the sound with a more focused stereo image, tighter bass and greater detail than before. Buy this before you invest in anything else.
Pros:
Better sound from your turntable and more convenient speed changes.
Cons:
Power cable from Speed Box to turntable is not very long thus restricting placement options. I had to go to another retailer and buy a longer aftermarket DC power cable and 2.1 mm adapters for both ends.

Pro-Ject Speedbox S

Written By Brian, Chicago, IL on Tuesday, April 02, 2013
Crutchfield Customer Review (What's this?)
 
The ease and convenience of being able to switch between 33 and 45 rpm by the touch of a button, is worth the price alone. On top of that, I have noticed a slight sound upgrade from my turntable since installing the speedbox S. I also own the Pro-ject Acryl-it platter and in my opinion the speedbox s increased the sound quality more than the platter. So if you're looking to buy either item and looking for the best bang for your buck, I'd say the speedbox s is the better upgrade between the 2.
Pros:
Black, fits the general color theme of my overall system. Small, easy to position on a table filled with other equipment
Cons:
None, does everything it's described to do very well.
