Ithe larger will beat it in the LF. I've recently been running woofTs with 2 x EL166 per box (in a variation of Scott's short ML-TL*), they kick, 4 hav to be quite more capable. *(is seems no matter where we go, Scott has had his hand in it :)) http://p10hifi.net/FAL/images/MKwT_woofWT-comp.jpg Let...

To put the record straight 'FONKENS' are a DaveD (Planet10) design. I don't believe our Scott has any input to these and their derivatives. More or less. I am often (happily) called on to express Scott's genius into a forum that comunicates the design so people build it. The key parameters of the F...

I believe these were the brainchild of DaveD at Planet10 and the speakers have been designed by Scott (Scottmoose). No, Dave wasn't involved. I think he's plotting something for his drivers, but in a very different configuration. The design is Scott's, but i have little doubt that the drawings i se...

If you have a tube amp typical of this forum, ie high output impedance SET, then i'd guess not really. That big impedance peak at just over 3 k is going to cause a peak in the FR right where your ear is most sensitive.

I notice in all your speaker builds you use 3/4" baltic plywood. Is there any reason you don't use 3/4" or 1" MDF? Yes, there us a reason it works better. 18mm of BB has about the same stiffness as 1.25" MDF, has less stored energy, is better damped, and will allow the builder t...

haha. You are a serious builder so i will take your last comment as funny. I'm serious... either your software makes curves that are very crude (and for some purposes useless), or your box is suffering from a lot of problems. Here is an (unsmoothed) impedance curve of out MTM (2xEL166 and an FF85 X...

That impedance curve sure is rough. Is that from poor software or is the box "shakin' all over"?

And as has been said before, you can't stop panels resonating, only push the resonant frequency up out of the "annoyance region", either by using stiffer panel material or by bracing. One also needs to keep in mind that the energy available to excite a resonance is inversly proportional t...

It is vestigial. It has little effect. It does allow an easy baffle swapping option and allows the fitting of wider and/or deeper drivers.

The FH3 has much less need for a wide sB, which would push the BS frequency down lifting up the lower midrange somewhat.

we has some done locally ( i.e. the Pacific NorthWet) - CNC milled 6mm aluminum, & powder coated, by the time you add spikes/ tiptoes / whatever, they need to sell for at least $70 per set. A set is for 1 speaker BTW. The rather nice pointy bits from PE are half the cost (and at cost), as a fav...

Probably not worth shipping to the UK, but we are currently in the midst of swapping a built set for a substanial number of CNCed aluminum bars for FH3 outriggers.

We had to make a wooden packing crate and pallette the speakers to go to Texas. The fellow at the receiving end said they probably would have survived an airdrop (personally i'd be fearful of the magnets snapping off)

I have lots to listen to, but won't be much help as it would require a trans-atlantic trip... lots of the guys here have nice FR kit, hopefully some near enuff will chime in.
