Thanks for all the feedback. I'm obviously new to making speakers and despite having read some books on cabinet design I'm not good at the lingo of the audiophile. Also despite my enjoyment of high quality audio I have tinnitus from my time in the military so I'm a proponent of don't pay for more than you can hear.
These speakers with the center channel I made sound so much better than the soundbar I used to have there. So I'm mostly happy. I'd like to wire the speakers so they are 4 ohms instead of 16 but my sony DH-550 receiver specs claim to only go down to 6 ohm. I've looked at other used receivers but am hard pressed to want to spend the money to replace what is currently working. I am building a stereo amplifier that goes down to 4 ohms, nothing special following a youtube video just waiting for a part to finish.
I feel like a lot of the system is being carried by the center channel ribbon tweeter,
Beston RT002A Ribbon Tweeter 6 Ohm, with the pair of
Tang Band W3-881SJ 3" playing back up due to having to have them wired up to 16 ohms. I have the cross over set at 2500Hz using airgap inductor and decent capacitors. But isn't that the point of the center channel?
The sound front seems unified for me with decent left right distinction when playing games and music. I haven't been able to play music at a decent volume but it all seems fine to me. I feel like I could be getting more out of the floor standing speakers but in the surround sound system I'm building I do not want them to take over, I'll see when I get the standalone stereo amp working how they sound independently of the rest of the system.
The two smaller side speakers are the first speakers I built which I think sound pretty good also but again I've never owned or messed with 'nice' speakers so it doesn't take a lot to impress me sound-wise.
Again I appreciate all the feedback and information, it helps me learn. Unfortunately I do not have the space or money to build an endless supply of speakers, despite how much fun building these has been. I am currently build one set of smaller floor standing surround speakers using the same 3" tang bands and in the below pictures. I am thinking about building a sub-woofer just to finish the set but to do a decent job it looks to be around $700 to build what I want so I am holding off on that for the time being. That would be the speaker, back plate, passive speakers, I want to make it passive speaker system, why because I think it would look cool, & the MDF to build.
Thanks
