Finally my new curved top and base Tannoy GRF's - all for me!

That's interesting as I recall being somewhat deterred when I asked about these drivers on the yahoo tannoy group some while back; the opinion was that these drivers were not really suited to domestic use without changes to the crossover, and even then...... I didn't get much response to be fair, don't think many had actually heard a pair.

I'm not after a pair or anything, just interested. They're definitely a lot more affordable than Golds/HPD's etc. You see various 'sound reinforcement' models cropping up for sale, sometimes very cheaply considering they were pretty expensive new. The Lynx-era models seem to be more in demand for some reason.

 

I must've missed that. The xover mods are simple(in the case of the CPA 15 anyway).The transformation a bigger box brings is revelatory too.
The pro/PA xover pushes the hf for cut through, the different slopes and hf level adjust makes them much sweeter sounding.
I haven't been able to find any T&S for the 12" though.

 

I'd have to agree with them as the CPA12's were in the supplied cabs.
You'd need a sub and at volume the treble got quite harsh and they needed more driving than when in the GRF cabs.

My room is quite bright too but overall I thought them pretty good all round and as said minor tuning would cure an treble vices.

Oddly the GRF cab made the treble a bit more pronounced at normal vols but it was not unpleasant or massively out of kilter - a little smoother would have been nice yes, but not nasty or anything like that. I reckon I could perceive there was higher frequencies avail than my 15's but my ears don't go that high - anymore...

 

All very interesting.

I really don't need any new drivers, but I might just keep half an eye open for any ridiculous bargains .

 

After a couple of weeks of trialling with the cabs as they worked best in my lounge, I decided to take out the optional extra felt damping on the rear outer section of the folded horn I had velcro'd in.
I felt with the higher ceiling and my sitting farther away from the cabs I could take everything they can throw out...
Oh yes! Dev & Rob there is more deep bass to come out of these babies than you heard when over CPA 12'ing!

I am now running the treble at +2 to regain the sort of near field monitor closeness and sparkle I previously had and that is matched well by the extra bass weight.
More is best perhaps

Further listening of course needed to confirm...

Oddly in the new room most CD's sound better?! I had pretty much come to the end of my tether with their sound in my lounge... Now I quite enjoy some - strange thing this sound! I can't explain this.

 

I wouldn't even try. Just enjoy your new room.

More bass you say? hmm..........

they weren't exactly lacking in that department.
