Members soundman11 Posted March 26, 2015 Members Share Posted March 26, 2015 I want to build a pair of 18 inch subs but do not know what design of cabs would be best for me. my speakers are 300 watts RMS. and I would like to get the most out of them that I can.my friend said band-pass cabs would be the best way to go but I'm not sure I'm new to building speaker cabs so I was looking to you guys to help me figure out what design is best for the best efficiency of the speakers I have.

Members agedhorse Posted March 27, 2015 Members Share Posted March 27, 2015 The best design is one you can try out before you buy. Bandpass is not the type of cabinet that I would choose unless it was forced down my throat, it's pretty much the worst of all worlds, and it's not a suitable cabinet for your drivers anyway. If you really feel you must roll your own, a simple ported cabinet is the way to go. Time to study up and learn how speaker cabinets work, otherwise your results will be as mediocre as the effort put into the design. Yes, there is some math.

Moderators MarkGifford-1 Posted March 27, 2015 Moderators Share Posted March 27, 2015 With the used prices of passive gear, I'd think that you could get some cabs for less than the cost of materials for building your own. Don't I see posts here about guys cutting up and burning old bass bins? MG Link to comment Share on other sites More sharing options...
Members agedhorse Posted March 27, 2015 Members Share Posted March 27, 2015 Yes, Mark, the used market is flooded with heave older mid grade subs. I cut some up a few years ago, there was no value whatsoever in the cabinets and I was able to get more for the drivers than I was for the entire cabinet loaded. Cost of shipping was some of the issue. Link to comment Share on other sites More sharing options...
Members Pro Sound Guy Posted March 27, 2015 Members Share Posted March 27, 2015 What I found on the number you provided was that is an Emminence loudspeaker made for YamahaYamaha JAY-7010,7011 and used in this boxhttp://usa.yamaha.com/products/live_sound/speakers/passive_speakers/concert_club_vc_series/cw118v/ Link to comment Share on other sites More sharing options...
Members Pro Sound Guy Posted March 27, 2015 Members Share Posted March 27, 2015 Note this gives you the box size but not the depth on the ports https://www.yamahacommercialaudiosystems.com/downloads/broch_pdfs/club_v_subwoofer_datasheet.pdf Sometimes DIY loudspeaker websites will have what you need as far as dimensions for the Yamaha Box in depth.

If I didn't have a rehearsal space for it to live in I'd pull the drivers ($105 each new) and waste the cab - not even worth cutting down into a 2x10 I think? Maybe a couple stoopid heavy 1x10's LOL ? Link to comment Share on other sites More sharing options...
Members Audiopile Posted March 29, 2015 Members Share Posted March 29, 2015 I'm new to building speaker cabs so I was looking to you guys to help me figure out what design is best for the best efficiency of the speakers I have. If it's any help, I'll suggest there's three basic design parameters to take into consideration: 1) Efficiency 2) Size 3) Bass Extension You can't improve on one without consideration of one or both of the others.

Members agedhorse Posted March 29, 2015 Members Share Posted March 29, 2015 What do yu plan on doing with the crossover network? That speaker series was designed to be actively crossed over between subs and tops. Good luck. Link to comment Share on other sites More sharing options...
Members twostone Posted April 5, 2015 Members Share Posted April 5, 2015 Might check these plan out if your into DIY http://www.bcspeakers.com/resources/suggested-designs/ but as mentioned, I'd look in the used market. Link to comment Share on other sites More sharing options...
