Concerning heat, I'm not sure if it will be a problem. I normally set the amp to a low level (the fan normally stays off, if it's necessary I'll turn the volume on the PC down and turn it up on the amp so the fan starts running). I also put a couple of old heat sinks on top of the receiver but I realise that won't make much of a difference.
The store doesn't give refunds, so if I buy them (I'll test them in-store) I can open the towers and check if there are ratings on the drivers. If I can't use them, I could still use the new bookshelfs together with the old ones and the center that I already have (the set only had one tower). But I'd prefer to keep the drivers the same where possible.
After quite a bit of digging I'm coming up empty-handed on both the TEK receiver and the DIXON speakers.
The speakers look remarkably like Pure Acoustics Supernova 8-F's (catalog link
), but the PA stuff is 4Ω.
The receiver also looks like some of the older Yamaha receivers, but an impedance rating of 8-16Ω makes me think it's a budget lookalike.
In any case, I personally wouldn't run lower impedance speakers on the receiver than rated. I say this primarily if the receiver amplifier module is what I suspect: a cheap multi-channel STK amplifier module rather than discrete amplifier stages.
- STK's are self-contained stereo amplifier ICs that are cheaper to implement and are "fine" if used within their specifications.
- Discrete amplifier stages involve transistor, FET, and etc (topologies may vary, but that's yet another discussion) and are a bit less prone to failure on undesigned loads. (spoiler: greater impedance loads are easier; they result in just less gain, or power going to the load. lower impedance loads typically result in just extra power dissipation which gets spread out across multiple stages of amplifier components so one thing doesn't catch all the heat)
STK's are not known to be the most robust things in the audio world. Don't get me wrong, for the price, from a manufacturing standpoint, and if implemented within the datasheet specifications STK's are acceptable.
Just to be sure can you look at the receiver?
Look in through the ventilation slats and see if you can notice the following:
See the black brick with all the pins roughly in the center and attached to the heatsink? That's an STK.
If you see this:
See the multiple black chips across the heatsink? That's a good sign it's discrete.
Just to be clear, I'm not saying "If it's discrete, attach whatever"

The placement of the speakers isn't the best but its the best I can do, I need a bigger room lol
Nice setup. I know the feeling about space haha.
My Tritrix placement was more or less dictated by what room I had available.Edited by Firestorm252 - 7/21/13 at 7:51pm
