Default Transmissin Line Speakers F.S. - Twin CHR-70

These speakers were built as prototypes on behalf of a friend, with the object of proving the basic concept worked as expected, and to fine tune the performance from the theoretical design.

I must say these have proven to be a big success and the delivery from these little 70cm drivers is quite something. Two Mark Audio CHR-70.2 drive units are used in independent transmissions lines. The cabinets are constructed in 18mm MDF, and measure 152.5cm high x 17.2cm wide x 34.5cm deep. The spiked outrigger supports add a little to the O/A height.

They can handle a variety of music genres and have a fast and crisp presentation with good bass. Iím quite impressed with the sound these CHR-70 gen2 drivers even though they have only around 20-hrs total play time. Things will only keep improving with careful break-in of the drivers over the next few hundred hours. They are a big step up in performance over the original CHR-70, of which I have 2-pr in a MLTL design. I know Chris Firth was impressed with the performance when I enlisted his help in the fine tuning of the finished speakers.

However, I do not have the space to keep these boxes and so, with the consent of the designer; they must go to a new home. So here is your chance to purchase a unique pair of speakers and for the low asking price of £350 for a quick sale.

Iíll gladly audition these at my place - pm me. This is highly recommended they do sound really good. Due their size these speakers will have to be collect only, so is restricted to UK buyers only, unfortunately. I could perhaps be persuaded to deliver them for the cost of fuel. Assuming they fit in my small car, that is.

I can fully veneer these cabinets for any prospective buyer and I think these would look stunning in say Oak or similar veneer. If interested in this option please pm me and we can talk prices.
