The Classix 2.5 (TMM) Loudspeaker Kit – Pair
A great beginners project that is easy on the budget.
The first time Paul fired up his first (successful) DIY project, the Dayton III by Wayne Jaeschke, it was a life-changing moment for him. What he had just made over the course of a few weekends, using only his own elbow grease and a pile of MDF and drivers, was so much better-sounding than anything he had ever owned before. And the money he’d spent on it all was a fraction of what he would have spent on something from the boutique HiFi stores. It was a true moment of bliss. Unfortunately, that bliss was short-lived as he came to the realization that simply plopping giant bookshelf speakers on top of chairs or old monkey-coffin speakers wasn’t going to cut it in the Spouse Approval Factor department. And so he spent the following several weekends doing the (unexpected) project of making speaker stands.
Paul’s next step:
Over the years, it has always eaten away at him: what would it be like if you could take a project like the Dayton III, with that beautiful deep bass from a pair of Dayton DC160, but make it into a small floor stander. Doesn’t that just make more sense?
The time had finally come to find out. What we have here is the Classix II design adapted into a 2.5-way floor stander. It builds on the benefits of the Classix II–big sound, deep bass, smallish cabinet–but benefits from more SPL output, and a 1-piece floor standing cabinet that one can finish to suit his own decor.
How does it sound?
As I said about the Classix II, if you are the type to hold your nose up to Pop, Rock, Rap, or R&B recordings, you’re not the right audience for these speakers. The Classix admits up-front that most modern recordings are flawed, but instead of showing you every flaw and wart of a recording, they emphasize what’s great about them. Deep, authoritative bass: check. Big soundstage: check. Surprisingly accurate imaging: check. Will they play “girl and a guitar” or a symphony? Sure, but what they really want to do is make you want to listen and re-listen to your favorite studio-produced CDs, and crank it! They’ll be detailed enough that you’ll find yourself hearing bits in the recording you’ve never noticed before, but not so much that it becomes fatiguing.
The overall sound is very similar to the Classix II, as it should be. However, a pair of woofers means you’re going to get more SPL. I’d estimate the sensitivity of these to be around 87 dB @ 1 watt.
What do I get?
We start you off with really good crossover components. The only entry-level parts are the terminal cups and the PVC port. I give you upgrade options for both. If you have terminals in mind that are not an option, feel free to request them in the comments field. The PVC pipe comes with a trim ring (not shown) to dress up the end, but many insert the port from the back side of the baffle and do a round-over on the front side of the baffle. The photo above shows the large flared Precision Port option.
Here is what you get in the Bare Bones Version:
- 2 x Vifa, BC25TG15-05 Tweeter
- 4 x Dayton, DC160, 6.5″ Classic Woofer
