franksmith Ex Member	Re: who's going to be first Reply #2 - 03/21/06 at 17:17:40 I got mine not so long ago, They where the new fostex who melt if the wax coating is applied. I've been told the where coated with smething else but I don't have any clues that it's the case. So what would be the new modifications ?

I had the driver in december. They have the new phase plug of the dfr-8, the felt on the back of the cone. Except for the suspension they seem identical to the dfr-8.

I had them play 10-15 hours a day for 3 months (there is always music at home) so they are probably over a thousan hours.

The cabinets are with the alternate tuning.

I heard a pair of hdt made by someone else with about the same result but in a very small room. Slightly more bass but still not flat to 38hz.

From 100 hz and down there is a constant reduction in spl, the highs almost disapear after 16khz.

I made the measurement at 1m in my big room.

The measurement where made only to confirm the listening impression.

The bass is very fast, clean with a lot of impacts and pleasant but in no way flat to 38hz.

I'm actualy boosting them with a pair of OB 12" drivers.

But it looks like you are in prime position to pull a D.I.Y job on the cones and apply the surround youre self . I think you can get them of the Dec-site look´s like the G08A ???

But the suspension probably makes more difference than anything else! (the other two main ones being cone coating and phase plug change)

Yeah, no way the driver goes 38-20K with any resonable output. That said, what it does in the 80-16K range is VERY good for the price of admission.

Someone else besides me REALLY has to try using the Aurum Cantus G2Si ribbon tweeter with the HDT's (running through a good 1uf cap). I don't think you will be disappointed and this is a cheap, and reversible tweak. And I'd like to hear others opinions of this..

Hello Gnat leader,

Our contract finally settled ( three YEARS overdue ), so I've got a FAIR amount of backpay coming, of which I will be spending a good portion. I will be buying the new drivers and adding the ribbon. Best estimates are 3-4 months, but I will take the plunge and give you my thoughts. I have heard the ribbon in another loudspeaker, and I think it's fabulous. I have NO DOUBT it will do great things to my HDTs, which I will also do with the alternate tunung.

Cheers, Bill :D

A pair of YAMAHA YST-SW215 Powered Subwoofer in the above picture has done right by me. Not the last word in extension or output/volume level, but adds authority without messing things up - especially for the rediculously low price of $200 for a pair. I recommend two unless your room is extremely small.

For better or worse I have the new drivers and the cabinets (HDT) are nearly done with glue up. I say nearly because I just came across these version 2 mods??? Longer port tubes, foam here and there, etc., I'm debating on doing the cabinet mods now while it is easy to do so. There was no mention in the plans of these mods so I'm a little uneasy about it. This is my first venture into audiophile level speakers so I don't want to make any silly missteps if possible.

To mod or not to mod, that is indeed the question....
