PRO9-TL quarter-wave Transmission Line Loudspeakers


Recommended Posts

Item Condition: Used
Shipping Options: Pickup available and you can audition.
Suburb or Town: Ferndown
Payment Method: PayPal or Cash on Pickup
Reason for selling: Upgrade

I am reluctantly selling a pair of original Chris Rogers PRO9-TL quarter-wave transmission line loudspeakers finished in teak wood veneer.  These are the actual speakers that have featured in many of my reviews for Hi-Fi Choice magazine over the years. Based on the original Rogers’ design from Practical Hi-Fi and Audio, October 1976, these speakers have been significantly upgraded over the years with new Audax HD12 tweeters fitted with Russ Andrews’ Focus Rings and new Peerless K040-MRF midrange, all replaced recently.  The switches of the crossovers have been removed and then completely rebuilt with audiophile components throughout, including ClarityCap polypropylene capacitors, Mills audio grade resistors, and Mundorf 99% silver/1% gold wiring.  I am finally selling them as I needed to get some smaller speakers!

 

The cabinets are in good condition for their age.  The teak veneer has bubbled slightly in places but has been well looked-after with wax and teak oil. Collection only from Ferndown in Dorset.

Fantastic looking and great sounding speakers.

 

Many years ago I had Chris demonstrate his pair to me with his SIRAC Amp, but I remembered a different tweeter, a KK8 sticks in my mind.

 

If they had been in Australia I would have bought them without a doubt.

      Item Condition: Excellent Shipping Options: Pickup available but audition is not available.,Shipping is available at agreed cost. Suburb or Town: Tarragindi State: QLD Payment Method: Cash, Paypal Reason for selling: Change in priorities (toddler and new baby on the way) Further information: PMC Twenty5.22 bookshelf speakers for sale in oak. Supplied in original box and packaging as shown. Oak for some reason were not brought into Australia unless by special order, so they are hard to come by. I am the second owner.
       
      These were my end game speakers. For my purposes they were the perfect balance of price and performance. To step up (in my opinion) would require considerably more money. Only selling as we've a very active toddler and another baby on the way. It simply won't be practical to have these setup for the foreseeable future.
       
      The speakers and grills are in excellent condition. There is one mark on the underside of one of the speakers (as shown in the photo). It can't be seen in day to day use.
       
      As we've a newborn imminent so I cannot accommodate requests to audition. If you're unfamiliar with PMC speakers, there's a lengthy PMC owners thread on these forums you should check out.
