I have recently gotten the urge to build a two way no bigger than the Dayton 4 design but with a significant step up in sound quality. This won't be easy since the Dayton 4 is, in my opinion, a pretty amazing speaker given its 4.5L volume. It is not too hard to build a better sounding speaker if one is willing to go to a cabinet of 6 or more liters, but as you get below 5L it is tough to beat the TCP115 in terms of maximum SPL and lowest F3. I started a thread both here and at DIY audio, and the only driver anyone could suggest that would go a little lower and louder cost about $100 each. It was brought up that although the Dayton 4 design is impressive for its size, there is room for improvement in it's overall fidelity. The Peerless 830855 (Peerless by Tymphany SDS Series 830855 4" Woofer 8 Ohm) reportedly sounds very good, will accept being driven somewhat past Xmax well, and is almost able to equal the mighty TCP 115 in F3 and SPL.
So, I will be ordering a pair of the Peerless 4" and one or more of the tweeter candidates tomorrow. I went through my tweeter inventory today and was pleasantly surprised at what I have on hand in small diameter tweeters. Specifically, the: Dayton ND 16, Dayton ND20Fa -6, Dayton TD20F-4, Dayton ND25TA-4, Dayton ND28F-6 and the Peerless XT25 SC90-04. In addition, I have in my PE shopping cart, the Peerless DX 20 BF00-4 and the Peerless NE 25 VTS-04.
So, Im thinking I would like to cross over at around 2200-2500 to avoid woofer beaming and breakup issues. Since I still struggle with crossover design, a pairing that would not need more than 6 or 7 parts would be nice. Finally, I would like a tweeter that is a clear step up from the ND16 (which actually is pretty decent). Also, I have done several different builds with the XT25 SC90 and it probably is the best choice in many ways, BUT I would like to try something different if doing so isn't creating a significant loss in sound quality.
A long winded post, but I'm hoping that with all the detail provided I can get specific guidance from folks who have been doing this for decades!
Thanks in advance,
Jay
