Exciting new line of fullrange drivers from Feastrex

bamboo wood in a cabinet is like nothing I've ever encountered before. A rap on the side gives a "ping" as if it's marble or ceramic. Very quick decay. I think these cabinets will either sound very good or very bad. They will not be mediocre.

I would love to use bamboo for cabs and even have a large enough forest at the end of my street to provide me with all I could ever use, but the various tools maintenance/replacement cost required is just too high. I could get a welder to make it out of the better overall performing brushed stainless steel for less on average.

They think there is an over-reliance on T/S parameters and formulaic approaches to enclosure building in the DIY world.

Utter nonsense.

I have a suspicion (correct me if I'm wrong here) that nobody at Feastrex (Clark aside) actually knows all that much about loudspeaker enclosure design. If they did, that kind of idea would never even cross their mind.

I visited their place last winter and listened to all of their drivers in various boxes. These are very polite businessman with an honest passion for their product; I don't think they would want to say anything to offend anyone.
they had actually just finished building the MLTL design suggested to them and it sounded horrible. Maybe that helps to explain why they aren't enthused by that approach, whereas their own "cut and try" designs (which do progress according to a certain discipline based on what I could observe) played with varying degrees of greatness.
A Japanese friend explained to me that the Japanese rely very strongly on what their senses tell them and when computer predictions and sensory perception are in conflict, they go with their senses and are comfortable with that. maybe there is a bit of a cultural thing here and that in the West we like our machines to agree with us and even lead us and feel a stronger need to reconcile our sensory perceptions with the machines predictions.

They have to remember -people are doing them the favour by purchasing their drive units. They're not doing us a favour by somehow 'allowing us' to buy their product.

I don't think that their relative silence on those issues means anything more than they are approaching this with different priorities. I left with the impression that these are very honest and uncompromising people and do appreciate all of the notice and suggestions they have received. Surely they want to sustain their business long-term and they are trying their own way.

now if we could just get those numbers!

So they built a ML TL cabinet without using an analysis based on T/S parameters, which they cannot seem or consider important enough to measure, to design the geometry and it sounded horrible? Must be the ML TL concept at fault for sure.

As Martin says, I'm a little curious about how they managed to design an MLTL without using any driver parameters?

BTW -has someone here taken offense at something / anything? bcherry seems to be under the impression they have. Not sure who / what though.

I'm sure the people at Feastex are polite, and I'm sure they're passionate. But IMO their refusal to supply any driver measurements whatsoever is completely misguided, and is going to hurt them badly if they don't sort it now. I'm not saying this for the good of my health. I gain nothing either way.

Used properly (as in, in conjunction with other factors), a person will be able to design a better optimised enclosure far more quickly with these than by continual building / testing, which the vast majority of people who spend this much on a pair of drivers would not be overly enthusiastic at doing.

You know what would be really big time cool? I'm borrowing this from what Scott said, but how about circulating a pair or two of the entry level drivers( D5nf ) between some, or all of the highly respected designers here at diy ?

This is a big community, and if some of these guy's were to be highly impressed with what they hear, it would be some major cost effective advertising.. The drivers could be insured ,and maybe could be offered at a very nice price to the designers if they want to keep them, or auction them off for charity or something..

Steve of Decware did this sort of thing with his prototype Taboo amp. He circulated it around to some of his customers on his forum ,and they had a week or so to live with it, then send it on to the next person on the list. It was really neat to read each persons impression and just a way cool thing to do IMO, I ended up buying the Taboo amp largely based on that approach having never heard it, but reading the reviews etc. It's a excellent amp btw, two thumbs up and worth every penny...

For me if people like Nelson, Dave and Chris (P10), MJK, Scott, GM etc ,were to really enjoy these drivers and give them some praise ,I'd be fast tracking my saving up for them, so that's one sale right there .. How about it Mr. Teramoto? Dave

Hi Phil, speaking of numbers, I bought a woofer tester if you want to borrow it sometime.

You in SF also?
