I’ve decided to do a shoot-out between the highly regarded Polk RTi A9s and my $50,000 Snell A7 Illusions. I will require someone who is proficient with modifying loudspeakers, particularly the crossovers, however I don’t recommend changing the values or drivers unless there is an engineer who frequents these forums that can say otherwise. Here’s what I would like to do: Polish the RTi A9 cabinets to a mirror shine (I’ve seen a few others achieve this with their RTi A7s, and the results are exquisite), replace the existing speaker terminals with WBT-style (similar to what Polk did for the LSiM 707s), replace crossover parts like the capacitors with Jantzen or something of similar quality, use thicker wiring on the inside, as well as acoustic isolation spikes. Also, which service do you recommend for these improvements? Money is no object. For this demonstration, I’ll be using a brand-new McIntosh MC462 and C70.

That sounds nice pitdogg2, and I’d even be willing to pay top dollar for a nice box with glass on top (including labor), but such services seem very difficult to find (which is why I made this thread).

I actually liked how they sound, but do not own them....I just meant probably not a great idea to spend thousands modding them.

I would absolutely not recommend modifying the crossovers in any way. Not only would it be cost-prohibitive but any chances for audible improvement are virtually nil. Looking forward to hearing your comparisons. The Snell A7 Illusion will be difficult to beat but it will be interesting to hear how close the RTiA9 comes to that esteemed high end model.
