Upcoming projects
Just going to mention a few projects I will be working on over the next few months.
First up is completing my latest Design Team project. Details cannot be released as of yet - but I expect it to be a design that outpunches its price class due to the midwoofer selection. This midwoofer's little brother has made the rounds in a few popular and/or very well received designs and while I have never been overly impressed with the alleged bass quality from either (and this model is no different in that regards) but the midrange, - oh my.
Second is a design using the new Designer aluminum 6.5" + RS28A. I felt Dayton missed by a mile with the paper cone 6.5" Designer series, but the addition of a shorting ring and a much better cone will, I believe, address those shortcomings. I am very excited about this new series from Dayton.
The above are both engineered to be used in the now defunct 0.38 PE cabinet in gloss black.
Yesterday I had a chance to dissect a tweeter that showed up at my house, and what I discovered was enough to get me excited about using it in a project. It will be an all aluminum TM using drivers that both cost under $20. The midwoofer is the MCM 55-2669, a driver which I (and others) have found to be nearly unbelievable at the price point - and I think the guys who were at Iowa DIY when the famous Barbie Girl incident occurred will attest to their capabilities. The tweeter is a new model from MCM (a pair will be on the doorprize table, by the way) which has some serious build quality features - think a nearly perfect chamber design + copper pole piece cap. Give that some thought and ask yourself what $19 buys in a tweeter these days. The impedance sweep shows that a lot of thought went into the chamber design (are you listening Morel?) and the copper cap is not just for show as there is almost no rise in impedance above the (benign) impedance peak. The Fs is reasonably low at ~950Hz, too.
(note: pay attention to the scale - it is 1db divisions - and why it is jaggy on the bottom end)
It appears the breakup occurs just over 20K - so am curious to see if any distortion propogates below there. If ya'll can promise to keep it to yourselves until later in the game, I will upload the dissection pictures for your perusal.
Lastly, I am going to help a friend with a TM or two. Claus, if you are reading this I would like to help you with that Seas CA15RLY + Vifa NE25 we spoke about, and I would also like to help with a potential DSA115 + SB19 design. Let me know. Due to serious time constraints between work and family life, I am contracting the woodworking on my current designs. Needless to say (I'll say it anyways), making sawdust isn't in my time budget at the moment.
Any interest in one or all or some of these making the trip to Iowa this fall?
