Couple Questions (lemmy.ml)

If I put 2 8 ohm woofers in parallel, can I run them with a 4 ohm crossover and tweeter?
Is it a good idea to to use a bunch of amps instead of a single receiver for surround sound? Good analogue receivers are expensive and I don't have enough speakers to fill all the channels yet.

As such yes, but it is also a question of the sensitivity, frequency response etc. of the drivers - this is a great resource for beginning a diy build: https://www.diyaudio.com/community/threads/so-you-want-to-design-your-own-speaker-from-scratch.332688/
Generally i would say no, as you get quite a bit of functionality for the money from surround receivers. But if you only want to use pc as a source, have a surround sound card/output, doesnt want more than 7.1 surround/atmos then sure. It also depends on your budget.

Np. Thanks for the reply! You have so far been the second source of knowledge I have seen on question 2. I'll probably go the multiple amps route though as slowly building an amp farm is more budget friendly atm.

What is the surround source? Like, is it tv, dvd player, computer?

[–] [email protected] 1 points 10 months ago (1 children)

It's a desktop PC with mostly unbalanced analogue audio outputs. Eventually I plan to get a dac and run from pc to that to amp(s), but rn I have my priorities set on building my output.

Ah ok. It would certainly be a bit more awkward with multiple amps but doable, and probably better than nothing, at least until you get something more dedicated for it. Once the amps are set, you could just use the pc volume as a master.

My main source is also pc, but I run toslink (fiber optic) to my amp, it does the rest for surround. I find it sounds way better than when I used to run analog signals to the amp in my opinion.
