![]() ![]() With a poorly matched amplifier or no equivalent compensation, LF gain will be 'modest'.After listening to a Full-range setup assisted by a Subwoofer, I was bitten by the magic of vocal reproduction by full-rangers, also this was a easier step in achieving better sound quality mainly because hassles of crossover design and tweaking is skipped. It's one of the most highly damped drivers of its type and very much a specialist unit strictly speaking this also applies to the 206 and 208ESigma, but to a lesser extent. Ohms are given on a logarithmic scale on the right hand side of the graph.ĭefine 'better'. ![]() You are looking at the wrong part of the scale. Impedance curves are measured in ohms, not decibels. As you can see from their own horn design, which isn't particularly stellar in terms of LF gain. So much in fact that realistically speaking to use at its best in a back-loaded design you'd need an amplifier with a DF of < 1 (output impedance of 7ohms or higher into its nominal Re) or the equivalent amount of series resistance. Magnet weight tells you where a lot of the mass has gone I assume that the SOL unit, like some previous limited edition Fostex models, has something like a cobalt-lathanun magnet rather than a basic ferrite. ![]() If it isn't a foolish question, why do you give a rat's *** what the total weight of the driver is? This is not an indicator in itself of anything other than just that: the total weight of the driver. The FE208-SOL was a limited production model for the Japanese market combining (more or less) the 206 cone with the 208 basket and a dedicated motor + suspension. ![]() The FE208ESigma is the higher end model albeit with this unit Fostex restricted the HF BW to improve LF & midband performance. The FE206En is the standard production model. You guys are being great! Already thanks everybody for the help. I'm not so versed on deep technical language, still learning, so please, be patience, I'm doing my best to understand What are the differences between this 3 drivers when analyzing the impedance curve? I noticed there's a big deep on the FE208SOL down to 20db, meanwhile the FE206EN and FE206EZ have a more similar impedance curves.įE208SOL is a much better drivers on the bass frequencies department?Īppreciate the help from all, in order for me to understand better the most significant differences between this drivers. I can see that the FE206EN is the most light one, cone material is similar to Fe208-SOL, and this both extends till 20kHz, but the FE0280-SOL is much heavier than both, almost 9kg! per driver, meanwhile the FE208EZ extends only till 14kHz, it's heavier than FE206EN and half of the weight of the FE208-SOL.įE208EZ and FE208-SOL are similar in price, FE208-SOL a little more expensive, meanwhile FE206EN is much cheaper than both. Please, help me to understand more the main differences between this 3 Fostex drivers: ![]()
