Thanks Thomas, I'll look into those... Dave

It's nice to see these IB drivers using paper cones rather than being another poly product, the sq should be really good. Has there been a comparison of the AE and some of the other drivers here for ultimate sq? Dave

The idea of "ultimate sound quality" is rather moot when discussing $100-$200 drivers. That said all the drivers we recommend for IB use are quite good.
If you want "ultimate sound quality" there's a substantial increase in the price of admission. And truth be told, in the passband where we're using drivers, the audibility between high-end drivers and the ones we recommend would be questionable.

Thanks Thomas.. In the next year or less I'll be moving ,and what I'm trying to put together is a really awesome sq music system. I'm into the fullrange driver scene ,and use a tube amp for my mains(Decware Taboo).. I'll be looking at getting the Feastrex D5nf driver and possibly running OB baffles,but most likely a BVR ,or horn cab for my mains. Right now I use BIB's with Fostex fe108ez drivers so this will be a big step forward. I was looking at using those Eminence drivers I first mentioned in a isobaric 5cuf cab ,two drivers per cab, and two cabs total. Going IB really appeals to me especially if when I move I can accommodate that kind of set up, and would probably only need 4-15'' drivers total. I've already got a Reckhorn sub amp so I'll put it to use.. Dave

Dave , I have heard the Feastrex driver coupled seamlessly with a bottom end that goes to 20Hz flat (Eq'd). Fully active. The Feastrex was doing 200Hz up Honestly, whilst it was nice and simple, the mid/highs left me underwhelmed compared to a conventional MTM driver setup on top. Here is the article www.6moons.com/industryfeatures/sonicpurity/feastrex.htmlEnjoy

Were those the cabs that you heard in the 6moons article? I had my mind set on a pair of AER Mk1 drivers, but then heard of the price decrease soon on the Feastrex. Anyhow lots of different ways a person can spend money on this hobby and many choices in drivers and driver combo's etc.. Dave

Would you have any faves in the higher price level as sq best's?, or whats the best driver you ever heard? I was following the GR Research drivers with great interest, then saw your comment in the OB vrs IB thread, so not sure.. Dave

Would you have any faves in the higher price level as sq best's?, or whats the best driver you ever heard? For about $900ea these are pretty good... www.madisound.com/catalog/product_info.php?manufacturers_id=121&products_id=82There are some rather outrageous performance claims made in that thread, and no proof to back them up. Why anyone would pay $149 for those 12"s when we have 15" IB specific drivers starting at $100ea is beyond me. Dipole or IB subs need a TON of displacement. I tested dipoles and it took double the amount of drivers to get approximately the same amount of output as the drivers mounted in an IB. Unfortunately even with double the Vd the dipole wouldn't hit the low octaves like an IB does... FWIW anyone considering drivers should buy them now, because prices are going to go through the roof in the next 6-12 months..

Thanks, and sorry for my somewhat uneducated questions.. I guess I'm trying to figure out how IB may work with what I'm thinking on doing when funds permit.. I want to run a fullrange driver like the AER mk1, but most likely will go with the Feastrex D5nf driver(no I will not be changing my mind on drivers ;D).. In any event if I build a cab for either driver and add IB bass, things should be ok, but I'm toying with the idea of running the drivers OB, and wonder how IB will work ? Perhaps I may need to run an OB bass driver that will run up to say 200hz and go IB for some bottom reinforcement?. I'm hoping to keep things as simple as possible though.. If when I decide where my speakers in the new system will stay located, I could build a cab to house the IB drivers and have maybe the bottom open through the floor. Then have the OB baffle on top of each cab that houses the AER or Feastrex.. Maybe that would work very well as the drivers will act as one cab and I could bring the IB's up in Hz to where needed.. All this would depend on if I could vent through the floor though?, in each cab location.. Dave

Hmm, I wonder how a pair of cabs with 2 AE 15 IB's per cab open through the floor with a OB Feastrex on top would sound Dave

Dipole subs sound very good, they just don't play very deep unless one uses a ton of EQ.
A pair of dipole mounted 15"s on each side would be a nice 'almost' sub. Those same drivers could be used in an IB at a later date.

No, what I was thinking is building cabs for the AE 15 IB's ,but the cabs would really be manifolds with the bottoms open to the basement, and then the OB drivers would sit on top of those cabs on their baffles. So it would be IB all the way for the lows and OB for the rest Dave

All depends on whether or not the optimal room location for the mains is the optimal location for the subs.

Well I guess its back to the drawing board then, and I can't draw Anyhow just trying to get ideas and such. I don't even know what my room will be like yet, so it's all just seeking out ideas and knowledge for now.. Perhaps I'll build the recommended cab for the drivers first and have a reference point, then introduce some low end and go from there. Thanks for the help, and for given my old brain some stuff to ponder... Dave
