I bought an Amplifi 150 here in Australia. I bought it purely as a jam along and learning tool, and the fact that it was advertised as a great HiFi music playback system. After unboxing, I plugged in guitar and played around with the built in presets, something was wrong(?). Very little low end, and not much in the way of volume. Certainly not loud as I had read about in advertising and reviews.
Next I tried music playback from an ipad through bluetooth, again, really disapointing low end, I understand using the 12 inch speaker as a guitar and so called sub woofer there would be some compromise, but the bass response was really disapointing. I boosted low end on the ipad equalizer, still really lacking in bass. I tried running a cable from the ipad to AUX in, tried it from a laptop to AUX in, and manually pushed low end frequencies on the itunes equalizer, which just made the unit clip.
Sound is all relative to an an individuals perception, so I played the same audio file through 6 inch studio monitors and had substantially more low end response compared to the Amplifi, I then played the same guitar through a Vox Cambridge with a 10 inch speaker and compared it to the Amplifi, again more low end.
I rang the shop where I purchased it from, and asked their opinion, they told me it was a very loud amp, with more bass "kick" than some of the PA systems they sell. So they put me in touch with Line 6 support. I was told to update the software, which I did, with no change. Another Amplifi 150 was sent out to me, and disapointingly the same sound. So I have either tried two dud amps or this is actually how they sound.
The Amplifi, concept is great, it suits me as an loungeroom guitar hero, but if this is what they sound like then it does not achieve well as a music playback speaker or a guitar amp. I think it is going to have to go on ebay.
Anyone else, had similar experience?
