Hi all, it’s my first post here and I’m a noob when it comes to the technical side of audio, but that’s why I joined these forums. I am looking to build a small open baffle guitar amp, and need some good 3” drivers that would be suited to this application. After doing a fair bit of research I’ve pretty much settled on going with the HiVi B3N or M3N. The Tang Bands look nice too, but the HiVi’s seem to give much better low end (which is important, since a guitar’s frequency range is about 75-5000 Hz).
Getting to the point, which do you recommend given my application? Looking at the specs, it would seem the B3N would do the best job in an open baffle, with its low resonant frequency of 77 Hz, and high Qts of 0.86. However, many people say the M3N is capable of going much lower than the B3N, which struggles at frequencies below 100 Hz. Opinions anyone?

Muffin Man:
Zaph tested the the square frame version of the B3N (the B3S) and said this about them: "Below 130hz, bass turns to thick mud. *Do Not* run this speaker without some sort of subwoofer crossover, preferably active at 150hz LR4" (http://zaphaudio.com/smalltest/). However he liked the driver enough to design a fullrange speaker around them (see http://zaphaudio.com/audio-speaker18.html). I own 5 of the B3N drivers and love them but use a small sub.
Note that a guitar amp has an open back but technically is a "u-frame" baffle not an "open baffle" or OB. To get deeper bass in a small package you'll need to consider a sealed or vented enclosure and a small midwoofer (rather than a fullrange driver). Maybe consider the Tangband W5-704D (also tested by Zaph at http://zaphaudio.com/5.5test/).
