DIY PROAC 2.5 Clone (Part- 3)

Continuation


Finally, the custom made clone cabinets arrived! It was delivered in a wooden crate with a label indicating the contents have a combined weight of 56kg!

The physical dimensions were to specifications and the purchased bass port fits perfectly!

Testing how the bass port fits into the rear port opening. The crossover will be position opposite of the end of bass port, with most of the weight support by the bracing. Will use a velcro mechanism to hold the crossover to the internal wall

Since I requested for the bracing, had to literally force foam onto the bottom half of the cabinet. This is necessary to reduce unnecessary reverberations there. Had open-up a B&W 800 series before and that's what they use as well.

Will be using MDM-2 in the top half of the cabinet.

Initial insertion of the ScanSpeak drivers onto the cabinets provided such a prefect fit I did not even have to deploy the screws for the first week of initial testing!

Initial usage was jaw dropping! Really sweet with bass to match ... no wonder the ProAc 2.5 is hardly available in the resale market.

It is a suprisingly power hungry speaker though. Will dig out my 200watt's power amplifiers once I have a chance to cleanup the room.

Shall update again once I have a chance to burn them in...
