Hello Everyone,

This is my first post here on talkbass. I've been surfing the site and it looks really great.

Anyway, I have a Peavey TKO 115 combo amp that I'd like to get a little more out of if possible. I've never connected another speaker cabinet to it and was wondering if anyone had any suggestions on what might work well.

The manual says that the ext speaker out jack is in parallel with the internal speaker, which is rated at 8 ohms. Also, it says that any external speaker used should have an impedance of not less than 8 ohms. So, if I understand all this correctly, it sounds as though adding an external 8 ohm speaker will not increase power output, but rather just spread the sound over more speakers.

Does this sound correct? Any suggestion would be greatly appreciated.

Adding an external 8 ohm speaker WILL increase power output because the amp would then see a 4 ohm load. Power output will increase by about 40%. That's how you get full power out of it.

Check out the Headliner 115.

Bbby,

Thanks for the info.

So...when an 8 ohm external speaker is run in parallel with the 8 ohm internal speaker, impedance drops to 4 ohms?? I guess I had it backwards. I thought that happened in a serial connection.

I will check out the speaker you mentioned.

Thanks

Bbby,

I just checked out the Headliner 115 and noticed that there is also a 210 version. Would this be a better choice to add to the existing 15 inch speaker inside the TKO combo? My thinking is that perhaps two different speaker sizes might add to a broader range of tone.

Many thanks for your help

Hey flyer, welcome to the forum ! Most people here don't recommend mixing speaker sizes for various sonic reasons. Your 15" speaker is giving you a pretty full spectrum of sound and most would recommend another 15 to get the most from your amp.

IMHO mixing different size speakers is a crap shoot. You might get good results with a 2x10 and 1x15 setup at home but it may sound bad in a bar or it might sound good in one bar and sound bad in others. It is just easier to stay with the same size cabs

I saw/heard a 210 + TKO and was pretty damn good! I'd go that route myself. The 10's really added a whole lot that the 15 was missing.

As was already said, sometimes mixing speaker sizes causes phase problems. You can also have issues with using a non-ported cab with a ported one. I have heard 210's and 410's that sounded great paired up with your amp, but they were ported, and the cabinet tuning was close to the combo tuning. The Headliner 210 is not ported. Some people love the 210, but I'm not a fan of that particular cab. Try it out if you can. The 210TVX was great with it. It has been discontinued for a few years now, but they are still out there new and used.
