Otherwise it sounded a bit "sat on".Not so easy to fix was the problem that the bass sounded rather tubby andnot very deep.
#TANNOY DUAL CONCENTRIC DRIVERS FOR SALE DRIVER#
One of the problems I had with the Lancaster box was that it is too short.When I put it on some bricks to get the driver up to seated ear height thesound opened up considerably. Both Lancaster versions sounded rather congested compared to thedrivers in my new big boxes and with the various improvement described below. These sound OK but with even less bass than my portedversion. In this case the port was sealed up, apparentlyat the Tannoy factory. Afriend bought a pair of 15" Monitor Golds in a nearly identical enclosuretraded in at a local HiFi shop. The original Tannoy box was a Lancaster enclosure(54cm w x 31cm d x 84cm h) with a simple slot cut in the front panel. In my case I have bass down to 20Hz,high efficiency and boxes the size of domestic refrigerators, but don'tthink this means the speakers give only big sound. If you wanthigh efficiency, you must either give up low bass or small, neat boxes the physics says you can't have both. Also high efficiency speakers tend to sound rather more "effortless" perhaps due to less heat being dissipated in their voice coils. Among other things it allows amplifier design to be freed ofthe compromises and/or expense that are required for high power and highgain. High efficiency is a great virtuein speakers. This article should have enough in itthat could be applied to other speakers too.Īmong their advantages are that they are efficientenough to allow the use of low power class A amplification, in my case ahome-built single-ended triode amplifier. The speakers started out sounding promising. Now I have them in a much better and bigger box and havemade some other changes. These were purchased at a garage salea few years ago in the cheapest and most basic original Tannoy box thatI have heard of. This article describes my experiences with a pair of 15" Tannoy MonitorGold dual concentric speaker drivers. Improving the Performance ofa Classic Tannoy Driver.
