I've been packing, moving into a new house, and unpacking for the fewcouple of weeks so I've not had time to provide any updates recently. However, I did get all the parts ordered for my final Parts Express Design Team build. This last one is going to be a beast. After going back and forth for a while, I finally settled on the following: a pair of Morel Supreme ST-1108 tweeters for the top and the Peerless (Vifa) NE149W-08 for the mid, anchored by an Dayton Audio RSS265HF-4 and one of the brand new matching RSS265PR.
This will be the biggest build I’ve done so far, and definitely the most high-end (read expensive). I built a very similar build for a customer a few years ago and it was what I consider the best build I’ve done sound quality wise. I’ve been wanting to revisit the concept in a floor stander for myself for a while now, and this was the chance to take it up to the next level. The slightly larger mid should provide a little more impact in the lower midrange and will likely have a little bit lower distortion as well. The tweeter got upgraded to the Morel Supreme. I got a chance to use these once before and I was very impressed with the sound. I try not to use a lot of audiophile terms but I don’t have much else to describe it. In the speaker rebuilt for a customer, it made Norah Jones some simply more “breathy” and real than any other speaker I’ve built. The RSS265 provides low distortion and good impact from the larger cone area, and the matching passive makes for a better look overall and allows me to front mount both into a base for the mid/tweeter. I’ll likely go with the woofer on the bottom to try and maximize floor gain and keep the sensitivity up. The passive will be over the top of it. Since they both share the same basic frame, this will allow me to swap positions if I decide I can’t get the woofer on the floor to sound right. I plan on making the mid/tweeter section separate to make it a little easier to move these around. They will likely be pretty heavy. I’m planning on using some multi-layer construction with weighted panels (probably granite) and Green Glue to try and damp these cabinets to the extreme. I still haven’t decided on the look yet, which I guess I need to do soon before I start building.
