[QUOTE="Peter Morris, post: 145903, member: 652"] Re: Double 10 and Horn Before the BMS I was using an Eighteen Sound NSD1480N. It was a very good driver but not happy going below about 800 – 900 Hz. At that frequency the two 10” drivers are still not playing that well together, it works, but it’s not best solution. A couple of examples of dual 10” cabinets that are very good are EAW’s KF394 and JTR Noesis 3TX. Both of these use BMS dual diaphragm compression drivers and cross them very low. The trick is to get down to about 650Hz or less so the two 10” drivers more or less act as one driver and do not phase cancel each other when you are off axis. To do that you probably need a 4” diaphragm driver. I think all of these drivers will work: · Eighteen sound NSD4015N – 1.4 or ND4015Ti2 - 1.4 · RADIAN 951PB - 1.4 · RCF ND950 - 1.4 · I think B&C are going to release a 1.4” version of their DE1080 TN ... I would check this one out if the do. They will of course need quite a bit of CD horn correction EQ etc. I know RCF crosses the ND950 over at 650Hz their TT5a. It uses the same horn as the Dual 10 (HF950). I have also AB my Dual 12 and Dual 10 against the smaller RCF TT 2a. The TT is an excellent speaker, up there with the best that money can buy, but the 4594 sounds better. FWIW the TT2a uses a ND850 compression driver on the HF950 horn. [/QUOTE]
