Peavey Tour TNT 115 upgrade?

theos · #1 11-26-2011, 01:48 AM

I picked up a solid little combo in a trade. Seems great for small gigs. My question as far as upgrade.... The speaker sucks. Put any juice to it and it bottoms out. 300 watts, 600 with an extension cab. What speaker could I use as a replacement that would allow me to get more out of the amp? Dumb question probably but would a Peavey low rider 15 work?

I have a Peavey TNT115 sitting doing nothing, and would like to know if I can upgrade the speaker in that, too!

Assuming they are similar amps, I hope somebody knows!

Cheers,

Jim

If you can add an ext cab, that's the way to get more out of the combo. otherwise, you'd need to model the inside cab of the combo with WinISD, and make your spkr choice that way. But adding an ext cab would still be the better option.

Actually, that's not correct. I had the opportunity to read the owners manual on the amp and it indicated that the amp as a standalone combo outputs approx 300, 48.9 VRMS/8 ohms watts. When you connect an 8 OHM extension cabinet to it the ohmage drops to 4 OHMS. Only then is the output power is bumped up to 450, 42.4VRMS/4 ohms.

600 watts is input power rating, which means how much hydro it takes to power the amp. I think Peavey's marketing of this amp has been very deceptive and caused a lot of confusion. If it was truly a 600 watt as a standalone combo, the price would be much higher than it is today.

That's my .02 cents worth.

But to go back to the original question, there's no doubt that adding an 8 ohm extension cabinet will help the overall performance and tone of the amp. Especially if you place the Tour TNT 115 directly on top of the extension cab. Just by getting the amp off the floor and closer to your ears will be a benefit.

wattage is important to a point as far as volume is concerned, but cone area is more important. 1,000,000,000,000 into a 15 inch speaker is still going to be as loud as a 15 inch speaker gets. Now 200 watts into four 15 inch speakers, and that will be a lot louder than than the single speaker regardless of how much power you are pushing through it.

Understood... I just thought that maybe Peavey's choice of speaker could have been better. To me it seems to have more power than that speaker can handle. I have to pull the eq down on the low frequency end to almost bottom. That's will volume knob maybe half way up.

Even if you put a different speaker in there,, unless it has a larger excursion distance it wont make a difference on the low end. Believe it or not, a single 15 speaker isnt necessarily the best speaker for low end. It depends on so much more than just the diameter of the speaker. IME 10's or even 12's have better low end when you have two or more of them together. My 810 cab has way more low end than my 115 cab.

I've got a 4x10 that blows the single 15 away. I was just looking for something easier to carry around. At least I don't have much in this amp. Don't get me wrong... For rehearsals and small gigs, it will carry. I guess I like tinkering a little too much. Haha

Most combo amps are built this way, with more power than the internal spkr can handle. Even the excellent Mesa Walkabout Scout 12, with it's 300 watts into a single 4 ohm 12" spkr is the same. Might seem counter-intuitive, but it really is up to the user to know the limitations of their gear. Aside from a fEARful or similar 2-way cabs, NO single driver combo or cab will take excessive power or low end.

Theos, Here's a link to the Peavey forum. There will be more players with experience with the TNT than here. Frequently the Peavey rep will get on and give factory suggestions.

+1. First you need to find out the specs on the driver that's in there and model it. Then you can model other drivers to see if an improvement is possible.
As to the wattage issue, of all the driver specs it's one of the least significant. What limits low frequency output isn't driver Pe, it's driver Xmax.
