Thanks Scott.

Btw, i trust your judgment and for my needs i'd be inclined to construct the smaller box standard pencil.

thanks!
The best bass I've had from a full-range driver (not counting my AN15) has been from an MLTL. I built a version of Dave's Castle (single driver version) using the EL-70. It's a paper cone driver designed by Mark (am I allowed to mention this on this forum ?) of only 4" but the bass is great (speaker standing on a hardwood floor). I would not want the complexity of adding a sub. I suspect that you will not need one either once you get your 12p into a better enclosure.

That's interesting and thought provoking, I guess I will have to decide without the pleasure of an audition. I suspect I will go for the bigger box as I like an expansive quality in the bass, and if I build the smaller one I suspect I will always be wondering "what if?"

One more question - people talk about using fiber fill for acoustic dampening, is this the standard stuff you stuff toys with or a brand name? I only ask because I cant seem to find it as a specific product for acoustic purposes.

Many thanks again for your time and support.

Thanks again, that's what I am after. I read earlier that the 12p was not designed to be near feild or "semi" near feild, but what's your opinion on what that constitutes? I have my speakers 4m away and was wondering, sorry if this is a silly question, wether I might be advised to queue up for the 10p instead?

4 meters isn't exactly near field. I listen to mine at ~3m, there are no issues.

Near field is on your desk, e.g. a computer speaker, recording console, etc.

Say within a meter.

sounds about right to me - at work the distance is almost exactly a meter, and at home less than 3 feet, depending on whether the chair is titled back with my feet up to stream a Jon Stewart interview
