There we go! Excellent. Confusion has been eliminated. I won't be pushing this system to reference volumes (or even anywhere close) so the suggestion to wire the drivers in series and the cabs in parallel is the approach I'll take.

Thanks all for helping me along.

Thanks for bearing with me sine. You've been very helpful and I am honestly not trying to waste your time. Yes, I see that I mis-stated the total impedance for series wired drivers. My apologies. When I made my immediately prior post, I was assuming that I would parallel wire the drivers in each cab...

I think I was concerned that if I take two cabs that each present 4 ohm loads and connect them to the amp in parallel, the total impedance will be well under 4 ohms (i.e. less than the bash's minimum impedance). On the other hand, if I connect the cabs to the amp in series, total impedance will be 8...

honestly, you can do either or. Read page 19 of your plans. It states 2 parallel drivers as 4 ohms, 2 series as 10 ohms. compare this to the power handling of the MCM and the output of the bash 300 at 4 and 10 ohms. One thing about series wiring and MCM. if you wire and series, and have your amp tu...

I have a very basic wiring question about a Tuba18 I’m building. The speaker has two MCM 55-2421 drivers (4 ohm speakers). I’m using a BASH 300 plate amp. Right now, I’ve just built this one cab but I fully expect to build a twin cabinet in the next month or so. Based on my limited understanding of ...

88 is on the money. Especially the part he wrote about volume. After building, break in and testing in general, if you find that you're more often inclined to try and turn bass volume up (the T18 won't match a Table Tuba or the like in terms of output), you should consider building another. Also, t...

1: for break in you can certainly use a CD player assuming your amp has the inputs for it, just hit the repeat button on the player so you can leave it for 12 hours or so. Before you attach the drivers use the multimeter on the speaker cables to make sure you're getting 10V. Once that's determined,...

I am completely new to speaker building so please forgive me in advance for what are surely very basic questions about (i) breaking in a driver for a Tuba 18 I’m building, and (ii) set up once my sub is constructed. I’m using two of the recommended MCM 8 inch drivers and a BASH 300 plate amp from Pa...
