Spec'in Speaks for a tweed Super build

FiddlinJim · August 14th, 2006, 06:37 PM

Hey builders,

I'm starting to plan out a build for a 5F4 (2x10, about 35 watts). I've only built one amp (tweed 5F2-a) and never owned a multi-speaker combo, so bear with me...

I'm looking at Weber 10A125 speakers for this. Since the amp is "about" 35 watts, do I need each speaker to be rated at half of that? So, a 20 watt is OK, or do I want/need the 30 watt ones? I'm assuming I want 8 ohm, right?

More questions will probably be coming!

I built the same amp a few years ago with a pair of 30W 10A125 speakers. Great sound. Not much speaker breakup happening -- the amp was clean a long ways up the dial.

I'd go with the 30 Watt versions.

Thanks guys. I do want max clean; I've got the Princeton for "unclean". I just got a line on a pair of barely used 30 watt 10A125's here locally for a decent price.

Love the 5F4. I built one about 5 years ago. I put a 15 in mine a 15A125 30 watt (P15Q). For max clean I would also use the two 30 watt 10A125

For headroom, the 35 watt 10A125 is perfect. I have 3 of these in a Clark Tyger. Yes, it's a loud, clean and punchy sound. Warm and singing too. It's hard to beat the tone of these for alnicos. They're more clean than not, but I do get a smooth, airy kind of compression and drive at louder volumes. Great sounding speakers.

Good to hear it. I bought the used 10A125's I was talking about last night. The 5F4 is probably way too much amp for me, but I'm excited to build it. Wait 'till my wife finds out...
