Bill Fitzmaurice Posted October 20 Posted October 20 Celestion hired me to design compact lightweight enclosures for their TSQ 1845 and 2145 drivers. They're now posted on the Celestion site as free PDFs with youtube videos. https://celestion.com/blog/build-this-18-inch-bass-reflex-enclosure-featuring-the-tsq1845/ https://celestion.com/blog/build-this-21-inch-bass-reflex-enclosure-featuring-the-tsq2145/ 4 1 Quote
JPJ Posted October 20 Posted October 20 Wow these look great. Any idea of finished weight and recommended crossover frequency, or is that covered in the download? Quote
Bill Fitzmaurice Posted October 20 Author Posted October 20 They're very light, as they are built from 12mm plywood and the drivers are neo. The exact weight depends on the plywood species, but they're going to be lighter than most commercial offerings. Like any sub they should cross to the mains between 80 and 120 Hz. 2 Quote
Huge Hands Posted October 20 Posted October 20 They remind me of some EV single 18" subs a venue I worked in had about 26 years ago, and they were probably a good few years old then. They were probably about 10 times the weight of your designs, but those EVs used to act like they had sold their soul to the sub-frequency devil and rumble away like mad! I have fond memories of them - I assume yours will be just as good if not better! Quote
Phil Starr Posted October 21 Posted October 21 Congratulations upon getting this commision Bill I'm sure it will be a useful resource for many people Quote
Bill Fitzmaurice Posted October 21 Author Posted October 21 Thanks. Celestion hasn't been known for PA drivers for DIY but they're getting very strong in that market. 1 Quote

Those drivers you've used are pretty formidable Bill. Proper professional drivers and good ones at that. Stimulated by your designs I've been browsing the Celestion catalogue and they seem to have rationalised their cheaper offerings a little and to be moving upmarket, apart from their guitar speakers which has long been a speciality. I guess moving upmarket makes a lot of sense when you are manufacturing in a high cost environment like the UK or US. 2 Quote
