THAT is a lot of links. Measuring most any guitar speaker will show why the majority are no good for hifi. Peaky response and no bass are almost prerequisites.

Guitar speakers are voiced to have peaks in the top end (which ends about 5K). They have huge magnets and stiff surrounds so most have an Fs near 100Hz, despite the heavy cones. And, the accordion surrounds make them non-linear, with a Qts of close to 1. What more could you ask for?  I actually listen to a lot of music played through guitar speakers, as that's how I break them in. The bass in a TL (and they will go low in a TL) is very natural for bass guitar, not so inspiring for cello or even acoustic guitar. Kick drums however, sound dead on. Male vocals are... forward is an understatement. But it's the cymbals that will drive you from the room. Did I mention the cone of a guitar speaker is designed to have massive amounts of harmonic distortion? If you must, try one of these: http://www.wgs4.com/content/BHHP Very smooth through the highs (for a guitar speaker), but the weak magnet/heavy cone will want to make a nasty bump in the mid-bass.

The only guitar speaker that found its way into diy audio is Tone Tubby.
Lynn Olson likes the TT 12" alnico. People have used it with Lowthers or horn tweeters on top. Some also use the TT 8" fe version as a wide ranger. The rest is pretty much hopeless. But the alnico tubbies are not cheap in Europe. If you are after affordable alnico, look for vintage. Germany is probably the best place for finding vintage alnicos. I have got myself some beautiful new old stock Isophons on German ebay. 15-20 euros each. |

well, not all "guitar / musical instrument" speakers have "huge" magnets (relative to cone size) - eg Eminence Beta 12TA 34oz for 12" cone, FS at 60Hz avg sens= 99dB , while say Fostex FE163En weighs in a 38 oz for 6" full range ( Fs 56 and avg sens=93dB) - of course that's apples to oranges and I doubt anyone would use any of the Fostex FR drivers for guitar speakers (for long at least), but the reverse is not necessarily the case.
The Tone Tubby's are great, but certainly not the only guitar speakers that have found their way into DIY audio - see Eminence cited above, and of course there manufactures such as Hawthorne and Hammer Dynamics catering to the DIY crowd with custom OEM drivers from this same company
