3) Nashville 112 Installation
Just fitted the Telonics TSNEO-12-4 into a 112 - The speaker is fixed from the rear; to remove the old speaker you will need to remove the back panel and probably the reverb bag. It might be possible to fit the speaker without removing the reverb, but for just two screws it makes access to the speaker fixing nuts much easier, and when fitting the new speaker this might be essential (if you have a stud issue - explained later). Although we didn't do it, it might be an idea to remove the chassis, it makes access to the top fixing nut far easier. Remove the speaker connections - note Yellow is +ve and blue is -ve. Having removed all the nuts the speaker was still fixed solid to the front baffle - I'm guessing the paint wasn't completely cured when the speaker was fitted at Peavey. Carefully prize off the old speaker - the old speaker gasket will probably be stuck in parts to the baffle; remove all traces of the old gasket with a sharp knife. I'd suggest you get a vacuum out to suck away any debris before fitting the new speaker. Carefully lower the new speaker onto the studs, with the speaker connections pointing to the chassis; make sure you get it perfectly lined up before lowering or you could put a hole in the cone. We had a slight issue here - the fixing rim of the Telonics speaker basket is much thicker than the stock speaker, this means the Peavey fixing studs are only just long enough. Because one of the fixing studs wasn't quite pulled into poistion, at first we couldn't get the nut to pick up the thread - eventually we managed to fix this - it is important to ensure all the nuts are fitted. Important - The nuts were tightened using the previously described sequence. The stock speaker connections are fastons, these need to be removed and about 7mm of wire stripped. Cut the wire as close to the fastons as possible - they don't give you much spare wire! Connect the wires to the speaker - Yellow wire to +ve (Red terminal) and the Blue wire to the -ve (Black terminal) - Note you just push on the top and this opens up a hole in the side. Refit the chassis, reverb bag and back panel - job done!
Testing - This isn't a heavy amp with the stock speaker, but the Telonics speaker makes it even lighter. We tested the amp before and after fitting the speaker... Wow! Of all the amps and cabs so far this is the probably the most noticeable upgrade. The stock speaker isn't bad, but the Telonics speaker in my opinion is clearly a superior tone, right across the frequency range - I couldn't believe how well it handled the low C6 notes... I can't wait to try a 12" in a Cube...
