New pair of Curved GRF's come to live...

For follow-up I have now been been building a pair with curved to and base and full length grilles.

Birch ply prepped and ready to start



construction starts



Curved front deatiling



All internals and felted



Always nce to see a pair!



Full length grilles



Loaded with Alinco HPD drivers



They sound great!



I am really pleased with how these are turning out.

Bit of finishing and a staining to taste to go.

 

Excellent work Steve. I can't tell you how tempted I am to either have a go or place an order with you, but I will resist.

Sorry I haven't been able to take you up on your offer of a listen but I've not been feeling too well lately . Hopefully will be able to make it some time.

 

Sorry to hear that Dev. Hope you feel better / get well soon - Music is a great healer;-)

 

Very nice (again) Steve, wish I had the cash to buy a pair.

Notice much of a difference between the mk1 alnico HPD's and your mk2's?

 

Very, very little difference indeed. I had Mr Coco from Wigwam over at the time and we commented how the Tannoyist's CAN hear the slightest change between spec's.

Mine are bass tuned to my room so sounded more sorted in that dept - a taste thing really.
Other than that pretty much identical. These did have the same crossovers as mine.

The next pair have the older Gold's crossovers same Alinco Drivers) so there may be more difference there. I'll report back in about a month once I've built and tested them

 

Finished article cab#1 takes it place in the test zone.
I ran this HPD Alico mag and my 3828 side by side for a while - sounded great.



without the grille



Take your pick - they sound pretty much the same



Cab#2 takes it place



Oh yeah, here's a swatch of some colours to choose from - as many as Homebase, B&Q etc have also of course



Here it is again in daylight with the type of stain / finish marked.

 

I prefer the darker shade. Looks great.

 

wow, state of art, love them i do, may i say well done and congrrats, 10 out of 10,
nando.

 

I am really pleased with how these have turned out. Staining beautiful virgin birch was a leap of faith - but they came out well.

I made up some bass tuning felt panels for the internal rear - these worked really well - I made them removable - velcro so possible to tune for full bass for the larger room.

More importantly Alex, who came to pick them today up enthused over finish and sound on my system.

Alex just called me having listened to them for a few hours - ecstatic in improvement in sound over his Berkeley's.
He said it was staggering how much more composed and subtle they are esp. at higher vols where the Berkeley's just break down. Also lovely rich info full mid and lower bass.
He's been listening to them for hours and had a few hours to go by the sound of it!
Shows how important cabs are

Next pair of cabs will start this week.

 

Wow.Those look really excellent. I only wish I had the room for something that much bigger than my uber-Lancasters.... I even have a spare pair of 15" HPDs idling in the office system... One day!

 

Yet another pair

Been a few weeks and yet another pair are born
I won't bore you with more construction pics though...

These are finished in Ronseal dark oak.

Looks darker in this artificial light pic though


In daylight


Next to mine


The pair


Side on


I've got another pair to make up now - Will be curved top and base again but natural finish.

Spare pair of 15" HPDs idling in the office system...! you really should GRF cab them!

 

Steve, you've practically got a production line going there!

Nice work.

 

These 2 sets were a joint run as the guys knew each other...

I just enjoy making things and seeing / hearing the results.
It's amazing hearing from folk how much better these are over the the cabs Tannoy put most of their drivers into of the period.
Waste of good drivers - the difference is startling!

Took Alex all of 10 mins listening to say "I have to have a pair of these"!

 

Lovely stuff Steve. Approx how much should I be saving up for if I wasn't so Shahinian smitten?

 

Steve

They look fantastic. I've no experience of these drivers, TBH I've no experience of DIY speakers either. But I do have some questions:

What kind of bass range are you getting in your room at the moment, and how do your bass attenuation strips / pads affect matters?

In case anyone is so interested in Steve's rather lovely cabs that they're looking for suitable drivers, I'm unhappily selling my 15" HPD's due to urgent financial crisis brought on by deathwatch beetles .

I'll put an ad in the classifieds in a minute, so look there for details if you're interested.....

 

They look absolutely stunning. Drool, slobber...... Thanks for posting, brilliant stuff.
