Alrighty, let's try and clarify a few things here.
A few general rules for those of you creating interesting combinations of your existing IEM's.
1. Upgrades
If you have an IEM that has only one dedicated bass driver, it is likely that our existing crossovers allow this to be upgraded. A good example here is the W3/UM3X, LW3, or even perhaps a TWFK based IEM that doesn't already have a bass driver.
If you have a TWFK based IEM, we can add one, or even two bass drivers to it, allowing the TWFK to do what it does best. Mids and Highs.
2. Crossovers
Something to remember, we have in house 2 way, 3 way crossovers made for duals, triples, quads, sixes, eights. We won't offer the upgrade, if we don't have a preexisting (already developed and tested) crossover available for it.
3. Frankensteining is a RARITY.
The only time this might happen is if you had a TWFK based IEM that you wanted to use as part of an upgrade of an IEM that has DUAL LOW's already. Like the TF10 or SE530. In this case, we could use your dual lows of the TF10/SE530, scrap the existing high, add in the TWFK for high's and then add in two mid drivers for a six driver IEM.
If you think about it like this, you may understand why frankensteining does not usually work.
Let say we have a SF5 that we wanted to combine with our TF10. Both from UE right? So it should be no problem! Wrong.
Have a look at the rough diagram below that we quickly chucked together. It's shows quite clearly why you can't just slap IEM's together as there is frequency overlap, or you end up with 3 bass drivers, two that will cover the same frequency properly and one that will react differently. Hopefully this shed's some light and helps you guys in your attempts to figure out what you can combine.
Basically, as you can see with the TWFK, it has the most potential to be combined with something, simply because you can add a bass driver, a good crossover and have a great triple.
Lets run through a few combos.
I got a TF10 and a UE700 I want to combine the two can i? - Let's have a look at our crossovers. We could put in a 3 way crossover, so we have dual bass single mid, single high. So we'll scrap the existing TF10 high end driver. Or we could put in a three way crossover, add two mid drivers and let the TWFK only do the highs, also scrapping the existing TF10 high.
TF10 + SF5 - we could use a two way crossover and take the SF5 high and ditch the TF10 high...but why? Thats going backwards.
How about my W4 and my TF10. We've got four bass drivers here. The TF10 bass drivers cover a wider FR spectrum than the W4, so they will not work well together. The W4 has a mid driver and the TF10 doesn't so we have to keep that. Now we have two totally different high end drivers. See how this one just isn't ever going to happen?
4 - Custom tuning
We don't ever like doing this. The risk of ending up with something that you guys (our clients) don't like and then having an extended period of back forthing to work it out is not worth it. This includes oddities like combining stereo inputs into a single sided IEM.
5 - Warranty
Re-shells are covered by our standard one year on the shell. Drivers are not covered. For upgrades we'll cover the additional driver/drivers for a year. Haven't had one fail on us yet. Yes we can figure out which driver is damaged and if its not ours we'll charge you for the repair. Naturally, sockets, wiring etc, all covered for one year.
6 - Refits
30 days for a re-shell. We at UMG have a notification only policy. You must notify us of your intent to return them within 30 days for a refit, but we do want you to get your impressions to us ASAP for them to be refitted.
With our re-shelling service, you can pretty much guarantee that the most a fix is going to cost you is the full price of a re-shell, if say you stomp on your IEM's. Regarding driver damage, the worst that can happen is that we need to replace the driver, usually around $50 a pop.
Apart from our promo customers, we haven't left anyone out there to dry yet....JOKES.
I speak only for Unique Melody Global unfortunately. Including UM Aus/Brazil/Indonesia/Philippines/Malaysia/United Kingdom/ and select UMG representatives in the USA. Other dealers and representatives may have differing or better warranty policies, we leave this to them.
