[Heresy to Cornwall Conversion?]

I currently have a 4 ohm set of Heresy II speakers. Since the midranges, tweeters, and crossovers are virtually identical to the Cornwalls, how feasible is it to cannibalize the Heresys, have some Cornwall cabinets made, and replace the 12" woofers with 4-ohm 15" ones?

Even if it is technically feasible, how cost-efficient is this compared with selling the Heresys and just buying Cornwalls? Assuming that I could buy equivalent Cornwall IIs for about $850, and that my Heresys are worth $350, can I get cabinets built for $500? I have no idea what cabinetmakers charge nor what materials cost these days.

Finally, assuming that I opt for the "do it yourself" option, would it be cheaper for me to use veneered plywood or particle board (that I veneer myself) on the cabinets?

I know that this is a lot of questions, but I'm confident that the expertise resides here to answer them. My only other feasible option (should I not be able to find a used set of Cornwalls and opt not to build) is to buy some brand new Cornwall IIIs. Does anyone have experience with all the Cornwall models who could provide a commentary on the sonic advantages/disadvantages (ignoring cost) of new vs. older Cornwalls?

Thanks again for your input!

Thanks - you're right, the CWs have awesome bass. The rest of the spectrum aint too shabby either...

I've got "wanted" ads out on the local Craigslist for a pair. Once I find some, I'll post my Heresy II set here.

Thanks again - Glenn

Hello ladies & gentlemen - I'm new to the forums...

I need your sage advice, please, regarding my speaker dilemma. I have been using Heresy II speakers with a subwoofer. The sound has been fine, but there are three boxes to be dealt with - the two Heresies and the sub. I have taken the step of selling the sub, and find the Heresy's bass to be inadequate (even with a bit of judicious help from the (ahem) "tone control"). Since I'd like to have proper bass without a subwoofer, I have come up with the following options:

Option 1 - Sell the Heresy speakers on e-Bay and buy a set of Cornwalls (I don't have corners for a K-Horn). I have had Cornwalls before and find them to be acceptable so far as bass response goes. The 15" woofers, being operated as high in the sound spectrum as they are, don't have quite the midrange detail that I'd like, but this is a "low-effort, high return" solution. If I shop judiciously, I can find a set or Cornwalls in a nice veneer so that I don't have to futz about with finishing the birch plywood.

Option 2 - Cannibalize the Heresy speakers, buy or build a pair of Cornwall cabinets, and buy some "replacement Cornwall woofers" off of e-Bay or from Klipsch. Provided that I can find a nice pair of used Cornwall cabinets with damaged or missing drivers, this would be a "low cost" solution. The fly in this ointment is that my Heresy speakers are the (odd) 4-ohm model, and I'm not sure what the "replacement" 15" woofers would do with that crossover. If I have to build cabinets, this becomes a FAR less attractive option. Further, even if I go with this option, I'm still stuck with the "less than detailed" midrange from the high woofer-to-squawker crossover point. If I do have to build cabinets, I'm more prone to:

Option 3 - Sell the Heresy speakers on e-Bay and build a pair of "Corn-Scalas." To do this, I'd have to buy 15" woofers, a pair of La Scala or K-Horn crossovers, and the midrange horns with drivers (I already have a minty pair of EV T-35 tweeters sitting in the closet). Of course, if I'm going to this much trouble, I'd be more prone to put TWO 15" woofers per side into a more upright (K-horn sized) cabinet. The dual woofers per side might provide enough sensitivity to allow me the use of the midranges and tweeters from the K-horn crossover without further attenuation? I have owned La Scalas before, and like the midrange detail of the big midrange horn.

I'm sure that SOMEONE on these forums has, at one time or another, tried ALL of these options. I'd appreciate it if you'd be so kind as to share your experiences... Any other "out of the box" suggestions are also welcome. Since my experience has been exclusively with the older Klipsch products, I'm unfamiliar with the sound of the newer ones. My goals in this exercise are:

Deep bass (somewhere in the low 30's at least

High sensitivity (I'd like to run these things with low powered electronics

Minimum cost (my better half's priority)

Minimum labor (my woodworking skills are pathetic, but I can force myself if I have to)

Your thoughts? Thanks!
