Peeking inside a Carver Crimson 275 Tube Amplifier
on the caps in the Carver...Everything is built to a price point.  If they charged $500 more for the amp they could use better coupling caps.  I am sure it is a very nice amp.  I prefer octal tubes in the front end, but anyway, changing the coupli...

According to their site it is basically a shielded resistor.  I have no idea why that would be necessary, but anyway there is no hum of any sort, the speaker sounds great, I didn't change the values of any parts so the crossover functions as it al...

that is just a drain wire on the pathaudio resistor.  You don't even have to connect it if you don't care to.  I tied the two of them together and then soldered to woofer ground input.  They fit easily on the board

from above: Hi Don! I started to put together a parts list to modify the crossover caps. I like VCAP much. I've used their CuTFs before. Can you shed some light on where one could cut corners a bit to save cost? The reason I ask is that the m...

HiNo, I am not modding the cabinets at all.  Right now I have just damped the horns and woofer frames, and really improved the crossovers with far better parts.  If I ever wanted to sell the speakers I have not devalued them in any way, but rather...

That pretty much sums up the cornwall IV.  Lots of fun, a wee bit bass shy at the very bottom, but you can live with it because the bass is very fast and tuneful.   Yes, I would say they run out of steam somewhere in the 35 Hz range.  Would have t...

Agree, the proper way is with a speaker switch.  You can hook the two amps to a switch box and then have one set of leads to the speakers.  Toggle amps that way

HiDon Sachs here.  Someone posted above that they have my version of the Bob Latino kit.  Ummmmmmmm, no.   There is not really anything in common between the Latino kits and my amp.  The kits are great bang for the buck.  About all they have in co...

from above: I'd be careful what you wish for with upgrades and parts. I've had several speakers with great parts that made my ears ache or ring when played at much lower than safe levels. Frequency has much more to it than can be easily measured....

Yes, I have the X5 with ODAM caps (I got Clayton to try them) and the Cornwall IV. It is a tough call and I have to put the X5 back in the system in a couple of weeks when the Cornwalls are completely run in with the new caps and resistors.  A...

OK, I installed the 30 ohm and 8 ohm pathaudio resistors.  I am done and never opening that speaker again!First off, I understand the concepts of confirmation bias and controlled experiments.  I have a PhD and have analyzed tons of data.   I have ...

The crossover had an earlier iteration, but mine is the later one. A fellow posted the schematic on a klipsch forum, so if yours were made in the past year or so they probably have that schematic, but perhaps you should pull a woofer and check. If...

oh I will most likely never hear one unless I buy a pair.....  I am in SE British Columbia a LONG way from Nashville:)

I would love the hear the Volti Rival....  I bet it is really good.  Plus, swapping the resistors or the one exposed coupling cap is trivial.  The Cornwall IV, when fully tweaked is pretty good though:)

Well, I wouldn't say they were crap caps, just run of the mill MKP.  I put the best caps I have ever heard in.  That said, caps, like speakers, are a personal choice and others may prefer a different cap over the ODAM.  They are a great speaker wi...
