Harlech was second from the top next to the reimagined Howard. What was unique about these two Castle models at the time wasn't so much that they were a modern slim floor standing design from a company that had previously majored on small to large 'bookshelf' designs, but the fact that both were quarter wave transmission line (QWTL) designs, each venting at the bottom of the enclosure and absolutely requiring the large included spikes being fitted in order for the QWTL to operate properly*. All other Castle 'speakers had been reflex loaded up to this point, the lone exception being Kendal from this same period, a diminutive infinite baffle slim floor stander. The first time I heard Harlech was at our old Castle dealers, well away from the walls, and properly spiked onto concrete flooring. These were quite impressive with a Naim 250, with a big expanse of sound from such small floor standers, almost like the smaller Magnepan models in this respect. The 1997 Castle price list had these down as being £879.90 in standard finishes and £999.90 in deluxe, with deluxe being yew and santos rosewood, with standard being pretty much everything else.
* with some users mounting these on plinths over here such that the end of the line isn't venting into deep cut pile carpeting with spongy under-pad beneath.
