hey mark that's a good point & along that thinking wouldn't the internal volume also be changed by the fastrac cornwall horn because it's bigger than the stock horn? I wondr if ALK can adjust for that with the crossover?

oh ya, just to clarify I'd never pay full retail for that kind of stuff. I get all kinds of eflyers from a bunch of distributors & suppliers & jump on clerance sales & close out offers. I've seen that stuff on sale 50-75% off retail before so why not. from what you all are saying I feel confident that the fastrac is a quality horn that is a big step up from the stock horns & alot of people saying he's a great guy to deal with so I guess that's what I'll go with when the time comes

painful good or bad on the extra goodies?

my original want was the eliptrac but I emailed Dan & he said it won't fit in a stock cornwall cabinet with k77 driver & adapter (it would fit with a different driver but I want to keep the original drivers) ok the long story... my buddy has a pair of lascalla's, cornwalls, pro audio cervin vega cornwall clones & almost enough parts & pieces to build a pair of cornscallas. now he just got a lead on his dream pair of khorns so he's going to sell me his cornwalls. they are all original 1977's black, solid cabinets but paint is looking rough & no grills. my plans are pull out all components & take cabinets to our local guy & have them sanded & refinished, extra bracing installed & a new motorboard cut so I can still have all the original parts. I'm leaning towards the fastrac cornwall (to be different from my buddy who is going to use jbl butt cheek mid & baby butt cheek tweets in his cornscalla's) I'll get new diaphragms & gaskets from Bob Crites for k77's, talked with the guy at ALK & leaning towards the csw 450 crossovers. extra goodies will be insulation in cabinet, duelund silver oil in cotton wiring & probably cardas binding posts. that's why I'm looking for people who actually have the fastrac cornwall horns cause they'll be able to tell me how good or great of an improvement they make over the stock horns which imo aren't that good at all.

ya my google search turned up the same as your link but like I stated in my original post there seems to be no actual reviews on the fastrac vs original horn. a couple of people on a message board saying they think it sounds better isn't going to make me pull out the master card especially when shipping & exchange rate will bring them over $800

has anyone replaced their k400 horn with one of these? how do they sound? how big of an improvement? $560 us seems pretty steep especially when I can't find any reviews or opinions with google search. my other option is to use the jbl 2342 butt cheek horns (threaded) with the k77 drivers. lots of posts on those & all positive

look into audio space. I have the as3i (el34) integrated (absolute magic with jazz) upgrading stock tubes & power cord makes huge difference. my buddy has the kt88 version & loves it. they both sound fantastic with cornwalls. there's no built in phono stage but I'm a huge proponent of seperate components. you don't need a preamp! amp, power cord and upgrading tubes should only run you 2k. lots left over for a phono stage, interconnects & speaker cable or to modify your cornwalls (alk crossover & fastrac mid horn)

I think your design should work fine as you have it now. I suggest room treatments will have a huge impact. with the width of the room bass nodes in the corners should be far enough from the listening position to not have that "boominess" too bad but the width will play havoc with first reflections giving you an echo effect & those large windows on the back wall will also bounce sound back at you. look into hanging absorbition panels on walls & a couple well style diffusers on back wall. if you can have speakers 5 to 8 feet apart you'll be sitting far enough away that risers (not stands) will be a benefit. like the others say playing with distance from wall & toe in will be a matter of personal preference & will be the major factors of soundstage (width & depth perception & sound envelopment)
