Hi, I'm looking to build an inexpensive 1x15 cab myself. I am an experienced speaker builder. I am trying to choose between the Celestion BL15 and Eminence CA154 as I can get them for a good price locally. They are very similar in specs. BL15-300X-4: 96 dB/W/m Fs 48 Hz Vas 4.86 ft3 Xmax 4.25 mm Le 0.47 mH CA154: 96.9 dB/W/m Fs 51.1 Hz Vas 3.82 ft3 Xmax 5 mm Le 0.80 mH Right now I am leaning towards the CA154 because the lower Vas will make for a smaller cabinet which is at least moderately important to me, but I am looking for any feedback or opinion from anyone who has tried these drivers. Thanks.
