Pro-Ject Speed Box S 

A very useful accessory for many Pro-Ject turntables, that allows a built-in electronic speed change. The Speed ​​Box S performs this change by the push of a button between 33 and 45 rpm. The quartz regulation and filter circuit gives a far better speed stability for smooth and undisturbed motor operation. Speed ​​Box S is compatible with a lot of Pro-Ject turntables (see list above), and some also offer the possibility to play 78 rpm records with the addition of a special accessory pulley.



33/45 (78 with optional pulley):  

Pro-Ject Debut III, Debut Carbon (only U.S. version with 16 volt motor), 1-Anniversary, Art-1, 1-Xpression III & Classic, RPM-5.1  

33/45 (no 78 available, because pulley can not be changed):  

Essential, 2 Xperience Acryl & Classic, 6-perspeX, RPM 1.3, RPM 9.1X, RPM 9.2, RPM-10.1  

Caution! Do not use Speed ​​Box S with following turntables:  

Debut III E, Debut II Phono USB, Debut Carbon (all non-US versions), Essential Phono USB, Juke Box (all types), 1-Xpression III Comfort, X-tension (all types)

Excitement and new life to my records
Saturday, 28 March 2015  | 

I live where the mains power is poor, dirty and full of noise. So this little box indeed works excellent and brought new life to my turntable and records.
I've got a Pro-Ject 6perspex table, which always lacked excitement and emotion so far. But now I feel a lot of much more music coming from the speakers. It brings a real "hi-fi" feel to my TT. Speed and timing is far better now, mainly on cymbals and drums (now you indeed know when the cymbals start and end). Bass is not bloomy anymore, being deeper and clearer instead (you can hear bass notes instead of bass confusion). Of course every other settings are (and always have been) well adjusted (VTA, azimuth, capacitance, table level, etc.). So this box was actually which gave new life to my system. It's a safe and best buy for Pro-Ject tables, which often lack quartz regulated motor.

Small product that fits perfectly under TT plinth. Very well made and saves changing the position of the TT belt for 33 and 45 rpm's.

I found the Speedbox S to be a worthwhile upgrade for my Pro-ject turntable. The stability of rpm's leads to noticeable improvement in the sound quality, better bass, clearer treble and totally constant frequency of notes, no wavering or quivering of long drawn-out notes. I would recommend this product to anyone who owns a 16 Volt ac turntable. Worth the money without question!
