This is my old custom built combo cabinet, made new by replacing the speakers. I had some cheap Peavey 10" Sheffield speakers in it, but they were 4 ohm, 75 watt speakers and the cab was wired up as 8 ohm. I put them back in my Peavey 410 cab a while back and had been using that. I decided to bring my combo amp back out again, but with new speakers. I now have Eminence BP102 10" speakers in it. They are 8 ohm, 200 watt speakers, and the cab is wired up as 4 ohm. I use my Eden WT400 with it. According to WinISD, my cab is almost a perfect match for the BP102's. And the way it sounds I would agree. The low notes are much tighter and the tone is awesome. I can't get the volume I could with my 410 cab (for obvious reasons), but the tone is much better, and it gets plenty loud enough for the gigs I'll use it on. Which is to say, it's quite loud...enough to shake the floor and walls and give me that punch I like. I'll use it for any indoor gig (even somewhat larger rooms), but outdoors I'd need to use a different cab for sure. The thing I noticed most between the 410 cab and this 210 combo cab is that the low notes (I only use a 4 string, so the lowest is "E") are VERY tight and well defined. The 410 made the low notes sound a bit muddy...solid, but not as well defined. I find the Eminence BP102 10" speaker is a great replacement speaker (if your existing cab specs out), or a new speaker if one were to design a cab around it. Many thanks to those who helped me decide on which speaker to put in my cab. I had originally thought of using the B102 (the one with the whizzer cone), but I was (thankfully) talked out of it. Note that in the pic I have a tweeter in it, but it's not wired up and I don't think I will as the cab sounds awesome as is.
