Prices are going skywards, combo of rarity, far east and us lot talking them up;-)
Put in the right cabs they compete easily with modern speakers costing around those figures in IMHO but they have none of the depreciation and are first step on the horn ladder...
I am building a pair of rect. GRF's alike for Reds at the moment.
Same volume as usual and best 21mm Scandi birch ply but narrower and taller.
I spent a while with Hornresp modelling the back loaded horn to achieve same bass response.
They are a bit high forehead
/ take me to your leader but easier on room placement as are only 45cm wide. Driver height is same as other GRF's.
Here's a sneak preview.
I have done a listening test on one with one of my HPDs loaded. Sounds same as other cabs I've built. Need a stereo pair to really check them out listening wise and I will then do some HolmImpulse measurements to compare them in room.
I've had a couple of pairs of Golds / HPD's and the first pair I got the 3828's so once I've heard the Reds I'll know more about comparing.
So far a pair of Lockwood modded hard edge surround HPD's with no dust covers on tweeters and Tannoy/Lockwoods after market crossover upgrades where right up there.
