Will increasing size of amp improve sound quality?

Upgrade the speaker crossover networks will completely improve your speakers. It is easily the best thing I ever did for my audio systems.

I upgrade the Klipsch speaker crossover networks if you're interested.

Jnorth,

With the Klipsch speakers, the majority of the improvement comes from upgrading the caps, resistors and in some cases the iron core inductors. It's not a very difficult thing to do and it greatly improves any Klipsch speaker.

Jack,

I do Klipsch and other speaker manufacturer crossover upgrades. Typically what I do is, I walk you through getting the crossovers out of the speakers and then you just mail them to me. We would talk about the level of upgrade (e.g. film and foil caps, metallized polypropelene or PIO's). If I can pre-order the parts, I can do the mods in one evening and get them back out to you the next day.

There is NO DOUBT that upgrading my speaker crossovers brought me the most sonic benefits, more than any IC, PC or speaker cable. The crossover upgrade is across the entire frequency spectrum (high, mids, lows).

My upgrades have never exceeded $275 and without looking at a schematic, I would say to do your pair would probably be around the $200 area, and maybe less.

If your interested in talking about this more, email me at:

I'll give you my phone number and I try and answer all your questions. I will even send you before and after pictures so you can see my work.

Thanks,
Mike

Jack,

I believe the RB-75 has two speakers, a tweeter and a woofer. There are two wires to each that need to be diconnected (one + and -). There are probably four screws that hold the terminal cup to the speaker cabinet. This will need to be taken off and the crossover network is usually attached to it. The terminal cup/crossover network is the only thing that needs to be sent to me for the upgrade. The speaker cabinet and speakers stay with you.

Looking at the schematic, I see 3 resistors and 4 caps per board that would need to be replaced. There are two air core inductors in the right place, so those will be fine and will not need to be replaced. So the total will be 6 resistors and 8 caps. The resistors will be replaced with high quality non-inductive Mills resistors and the caps will be your choice. I usually use Kimber Kaps and that make a big improvement over the stock caps.

This would be a one/two evening job for me. I would try and pre-order the parts to expidite the crossover upgrade. This will make the turn-around time quick and your downtime minimal.

Hope this clears things up a little. Please let me know if you have anymore questions.

Thanks,
Mike

Perkadin,

Nobody ever said anything about "replacing a few parts with larger versions of themselves in a crossover network....". You obviously have never heard the before and after of a Klipsch crossover network that has been upgraded with better parts, I have. I can tell you that it made a huge difference on all three sets of my own Klipsch speakers. So yes, I've actually heard the differences of before and after. EVERYTHING was much better (highs, mids and lows).

I'll go on record and will offer a money back guarantee, that if it sounds worse than the stock version, I'll change it back free of charge and pay for shipping.

FYI...when I upgrade the crossover networks, I use the same value parts.
