Exciting new line of fullrange drivers from Feastrex

[bvan]

Hi dj, I'd suggest also trying the D5nf in a 2' wide baffle with the subs playing up to about 200hz. Would only cost a few dollars to try it out and it may sound better. Thats how I ran my D5nf open baffle. I never tried it as you have it though, and I'm not averse to running 15" drivers high (I currently run AE TD15M to 800hz), but the Feastrex might still be the better driver at 200-650hz. Worth a play around.

Either way, personally, I would high pass the Feastrex at 650hz or 200hz or whatever, rather than run them fullrange in OB.

1. My current speakers are TAD 4001 mid driver horns, 1601C 15 inch bass drivers in a tuned custom cabinet (similar to onken). The crossover is the passive stock Tad TN-2 and the crossover is at 650 hertz.
2. To get the Feastrex up and running I disconnected the 4001 horns, placed the Feastrex nude on the top of the Tad bass boxes at about ear level and connected the Feastrex and Tads to a SET 45 amp. So effectively the Tad is handling bass 650 hertz down with steepish 18db rolloff (I understand) and Feastrex full range.
3. Based on this configuration I was in shock in two ways. Firstly I wasn't expecting much but instead couldn't believe how incredibly musical the Feastrex played. The detail and refinement of these drivers are superb including an excellent soundstage for such tiny drivers. The second thing was how perfectly they integrated with TAD 1601c bass drivers. I think the TADs are about 95 db efficient. The Feastrex I've read in some places are 92, 95 and even 97. In any case they match the volume of the TADs perfectly. In addition there does not appear to be any crossover between the Feastrex and TAD from running the Feastrex nude full range. For example I'm not hearing heavy male vocals due to the Feastrex intruding into the Tads 650 hertz and under area.

So the questions I have are as follows:

1. Have I just fluked it? Are the Tad 1601s a match made in heaven? I'm hearing a beautiful mid and top end with excellent bass with the TAD without any perceived overlap between Feastrex and TAD.

So has anybody tested the rolloff frequency of the D5nf nude? The reason I ask, is I'm suspecting the nude Feastrex must starting dropping off around 800 hertz and then drop like a brick from 700 ? This would explain why there is no lower midrange coloration with the sound.
2. As far as baffle size and shape for a 650 rolloff what would anybody recommend? ie. would you suggest I keep it nude or mount the drivers in a small open baffle that doesn't materially exceed the width/length of the Feastrex. I am afraid if I make any type of baffle too big then it will start intruding into the Tads 650 hertz sandpit and interfere with the sheer "fluke" in great sound I've achieved on my first shot with these.

Thanks DJ

ps. As an aside I do have some limited experience with open baffles before. Used to own some PHY-HP SAG in open baffles so do love the open baffle sound. The only complaint I had was to get good bass the baffle had to be quite large.

djkiwi,
i am also planning OB with eminence LF and fertin or feastrex drivers.your feastrex OB how is the soundstaging,is it 3d holographic

Has anyone compared the sound difference in sound of Feastrex D5NF ,D5Ex and D5ex with CW upgrade,is the CW upgrade worthwhile

[BTW]

The CW upgrade applies to Field Coil models.. so D5nf Monster Alnico and D5 do not have this upgrade. I had my D9e Type1 upgraded to CW .. The CW upgrade improves the tone and the music is more natural and relax..

Hi Guys, I have a flat screen TV hanging on the wall above my fireplace and have been thinking about adding some inwall speakers. I had a whacky idea the other day of using the Feastrex DN5 for this purpose. Because the gas fireplace is there I have about 24 inches from the front of the wall to the back meaning there is plenty of space for the magnets.

I am going to put inwall speakers there anyway so thought I may as well give the Feastrex a crack first. If it doesn't sound any good I will replace them with something else I have on my inwall hit list. Anyone have any ideas on how this would sound or who has tried it?

Cheers
DJ

What's the space behind the spks like ? Will it be something like infinite baffle ?
