oldknotty Posted February 18, 2012 Share Posted February 18, 2012 For bit of DCC luddite like me , what is the difference between a bass reflex speaker and a bass enhanced speaker , I am looking to fit some in my DDC sound locos to improve the sound but I am getting more confused the deeper i dig :-) Thanks martin Link to post Share on other sites More sharing options...
kevpeo Posted February 18, 2012 Share Posted February 18, 2012 From my experience Martin, a good 'big un' is better than a good 'little un'! Or to put it another way, a speaker with the back box fitted is better than one without. A well-sealed back box is better than an unsealed one. A bass-enhanced is better than a 'std' speaker. A bass-reflex is better than a bass-enhanced, if, and it's a big 'if', you have the room to fit one in. And the bigger (deeper) the bass-reflex is, the better. Not all will agree with this of course, and a well-sealed 'std' speaker can often be louder in exhibition conditions, if not as 'bassy'. HTH, kev.

oldknotty Posted February 18, 2012 Author Share Posted February 18, 2012 Thanks Kev it helps I am looking at my alternatives here before I buy !! Martin Link to post Share on other sites More sharing options...
gridwatcher Posted February 20, 2012 Share Posted February 20, 2012 Agree with KEv. The only proviso I would add is that some locos, that are naturally bassy, improve no end. Think class 60 class 37 etc. If the loco is naturally higher frequency sounds then experiment first. Things like class 58s 56s HSTs that have a high end scream etc etc may need care. The Bass Reflex speakers sometimes muffle the higher end too much. The large conventional speaker like this might be best compromise if you can fit it in? http://www.abcomponents.co.uk/ABS-230-RC Think this if Legomanbiffos favourite!!??

legomanbiffo Posted February 21, 2012 Share Posted February 21, 2012 For bit of DCC luddite like me , what is the difference between a bass reflex speaker and a bass enhanced speaker , I am looking to fit some in my DDC sound locos to improve the sound but I am getting more confused the deeper i dig :-) Thanks martin First off, bass enhanced is simply a marketing term. It's a speaker who's bass performance is better than the standard ESU speaker, hence the term 'enhanced'. Bass reflex on the other hand is a technical term for a design of loudspeaker enclosure which uses a tuned port to reinforce the sound at bass frequencies. It's bass performance is better again than the bass enhanced but it is physically bigger and won't fit in all locos. DCC Supplies and Digitrains both sell bass reflex speakers of slightly different sizes. I would say that the Digitrains one is slightly better but is physically bigger so this is to be expected (and again this will limit what you can fit it in). It's well worth buying a selection of speakers and trying them with your target loco to see which will fit and which sounds best. Blu-tac them to the side of the loco to have a quick listen before you commit yourself. The speaker Simon has linked to above doesn't come with an enclosure, you have to build it yourself. If you're happy doing that, and if it will fit (it's 28x40mm), it sounds fantastic. Hope this helps, Bif Link to post Share on other sites More sharing options...
oldknotty Posted February 21, 2012 Author Share Posted February 21, 2012 Building a custom speaker enclosure is not a problem as long as the thing will sound good once all the work is done .Thanks for the info Bif Link to post Share on other sites More sharing options...
Essex2Visuvesi Posted February 22, 2012 Share Posted February 22, 2012 Also for best sound the enclosure needs to match the specs of the speaker. Enclosing a speaker will Improve things but for best sound quality then the enclosure needs to have the correct air volume for the speaker used. This is quite a complex subject in itself enclosures can be ported, sealed, bandpass or a multitude of others. Here is a website with some of the basics http://www.bcae1.com/spboxnew2.htm its aimed at car audio but the theory transfers readily to DCC sound Link to post Share on other sites More sharing options...

Essex2Visuvesi Posted February 22, 2012 Share Posted February 22, 2012 I suggest going for ready made enclosures where possible.... take a look at caboose hobbies for speakers and enclosures http://www.caboosehobbies.com/catalog/index_brief.php Link to post Share on other sites More sharing options...
Poe Posted March 23, 2012 Share Posted March 23, 2012 As with hifi, the bigger the speaker the better the sound, bass ports help loads. If youve got a loco with a tender i highly recommend laptop speaker enclosures that have bass ports like these: http://www.ebay.co.u...=item3f03b8eb99 Link to post Share on other sites More sharing options...

Lady_Ava_Hay Posted March 23, 2012 Share Posted March 23, 2012 What ohm rating are these speakers? Are all these laptop speakers the same ohm rating? It doesn't specify on the E bay listing. Link to post Share on other sites More sharing options...
Poe Posted March 23, 2012 Share Posted March 23, 2012 The ones ive got are 4Ohms Mine gives out a 170Hz bass response which is deep for a speaker this small Search for some harman kardon speakers, they are normally in toshiba laptops they sound very good indeed, and rival pc desktop speakers. http://www.ebay.com/sch/i.html?_nkw=harman+kardon+laptop+speakers Link to post Share on other sites More sharing options...
RMweb Premium boxbrownie Posted April 12, 2012 RMweb Premium Share Posted April 12, 2012 Just ordered a few of these, various designs but all look small......should be interesting playing around with them at the very least, thanks for the heads-up Poe.

Mike Sheardown Posted April 13, 2012 Share Posted April 13, 2012 Hi Poe, Do you know if the 4 ohm speakers you recommend will work ok with both the v3.5 and v4 Loksound chips?? The recommended (by Loksound) speakers are 100 ohm and 8 ohm respectively. Thanks for your help Best Wishes Mike Link to post Share on other sites More sharing options...
cassey jones Posted April 14, 2012 Share Posted April 14, 2012 Mike, For loksound V3.5 - use only 100 ohm speakers For V4 use either 8ohm or 4 ohm speakers Link to post Share on other sites More sharing options...
Poe Posted April 15, 2012 Share Posted April 15, 2012 most pc laptop speakers are 8Ohms 2watt which give a rich bassy sound, 4ohm tend to sound tinny but a good enclosure should sort it, i only use 8ohm and 4 ohms in shunters Link to post Share on other sites More sharing options...

Mike Sheardown Posted April 15, 2012 Share Posted April 15, 2012 Cassey Jones and Poe, Thanks for your advice, I'll give these speakers a go with a V4 Loksound chip. Best wishes Mike Link to post Share on other sites More sharing options...
ThaneofFife Posted April 17, 2012 Share Posted April 17, 2012 Its a conundrum I have been mulling over for sometime whether to fit enhanced or reflex. This thread will certainly prove helpful in future sound installations. Link to post Share on other sites More sharing options...
