New Fostex RP open-backed planar magnetic headphone, TH500RP! Available now! - Page 7

post #91 of 508
Yup th600 are damn comfy and so far it looks like the band and pads are the same on these RPs. I'm still very interested in them, but the soundstage will have to be different (better, which is a tough ask) to th600 and maybe the signature as well to warrant a purchase for me. Otherwise I think I'd be better off with mad dog or alpha dog for situations requiring isolation (like work) as the th600 aren't great in that regard and leak a fair bit.

It would've been interesting if they'd gone for another new closed isolating RP around the 500 mark to take on the new shure 1540 which seems to be at quite a sweet spot (seems like only the alpha dog takes it on for price/fidelity). Who knows maybe fostex will do a closed one too

Fostex RP50 Prototype...and TE05!

You see, the RP50 prototype uses the same planar-magnetic driver found in the Fostex T50RP headphone that headphone DIYers love to modify. It is a really competent driver when placed in a well-designed enclosure, and I think Fostex has something very special in this driver alone. The show was too loud and commenting on prototypes under the circumstances would be silly, but I know these drivers can sound very good. I hope Fostex finds ways to use use them in a lot of products...even products made by others. Mr.Speakers uses them in his Alpha Dogs, which really are a spectacular headphone. The point is: The story of what Fostex does with its killer planar-magnetic driver might be very, very interesting...in lots of ways...''

I wonder if the RP50 is the official name, or just a name given by Tyll.

They must be joking. A driver that for several years sold for about $80, shipping included, is suddenly worth $500-600 with some tweaks to the housing?

 

Mind you, tweaks made by a company able to mass-produce, not tweaks made by one or two guys at home who had to source the phones from a 3rd party.

We will see. Its a lot more than tweaks! It's a high quality aluminium enclosure with grills! Thats a big step up over any of hifimans designs for me I hate that glossy plastic. And the pads and band alone rocket the price up (good cable too) - same as on $1000 th600 and $1800 th900. Prices always drop over time, and or course a plastic 'pro' monitor market headphone that has been around for practically 30yrs is going to be cheap. They can't just pump these ones out in a pre-existing production and assembly process like the t50rps and they don't know what the demand will be like. They are also more HiFi market than pro market and priced accordingly.

I doubt the driver will be exactly the same design its just based on it, same magnet layout etc, and at the end of the day it should be about the sound (but good looks help and this proto is looking a hell.of a lot nicer than t50rp to me). Don't forget the alpha dog is $600 and most people seem to think its warranted for the sound - and the enclosure has a lot to do with that. So if fostex's new open enclosure design nails it it'll be worth the $ !

I agree that it looks very good and it will probably be well-built, but what if the sound ends up being essentially stock T50RP? Given what we know about the driver and how to improve its, I wonder how they're going to do that in an open configuration. I think they have a challenge ahead of them.

Since everyone is speculating, I would like to point out that even if Fostex decides to use the same driver, that doesn't really effect the end result the same way our RP tweaks work. Here's just a few things to consider:

  • Same driver doesn't mean the same mounting setup. The driver may be used, but the configuration might be built from the ground up.
  • We know from modding that the RPs become less efficient, so who knows how Fostex engineers will compensate for that.
  • Resistance makes a difference as well, Fostex could easily tweak the Ohms to add clarity, balance, and scaling potential
.

We don't know much yet, I am curious to see what Fostex pulls off, then we can crack into it and mod away!

All good points.

 

But hopefully the Fostex engineers will do such a good job of everything that it won't require or be suited to modding :) (especially if these are at the speculated price point of 400-600)

Though I guess people still try to mod expensive Hifimans; simple things like pads/grills/cables can make a difference if you want a different sound sig

arnaud's impressions "The fostex open back prototype phone based on tr50p planar driver was a very pleasant change. It was driven by the latest small footprint dac/amp from Fostex and sounded so well balanced. That may be me, but my reference for planar sound is old quads or magnepans. The fostex sounded like that to me (mind you I haven't listened to planar speakers for a while). It wasn't harsh or shrill for any of the recordings, sounded very balanced, tight clean extended bass. The th900 felt a bit loose in the bass and tizzy in the upper mids in direct comparison. The other nice improvement over the th900 was the soundstage width as it definitely sounds more open. Last but not least: comfort and price. The prototype weights like a feather and the final product will preserve this apparently. The pads are soft and make a good seal without feeling the pressure, very nice. I never thought I'd own some planar gear but this one may make me reconsider. The price is also right it feels (around or less than th900)."

Ouch, so much for expectations for $400-$600.

 It seems that the Alpha Dog would be the better deal.

post #101 of 508
OK if its not a new driver that is indeed a lot more than expected for new housing band pads etc... Yes engineering and sounding more open yadayada but it's still not a totally new developed driver right? Guess we will see. If it was around he6 price and sounded better it would be worth it?

The RP prototype has had an update since the Fujiya event in October.

Fostex has changed the dampening and demoing it in the e-earphone festival today & tomorrow.

I like the treble presentation more in this latest revision. The highs are more smoothed out.

Is Fostex sharing any other information than this? Do they have a general release date or an idea of price yet?

I'm gonna be honest, I didn't even wanna go there. I'm happy that they're still doing sonic tweaks on this. They're still doing tweaks at the moment so I'm guessing not anytime soon...nor the price. I could be wrong though. I'll shoot them a mail after the new year's.

Appreciate the honesty... Just kinda sick of all these ortho/planar teasers with no follow-up.
