Hi. 

 

I am new to A/V and and in the progress of putting together a basic home theater setup.  I recently purchased a Yamaha RX-V375 amp.. I got a good deal on it, it is an entry level receiver, but has all the basic features I wanted.  My goal is to setup a 5.1 system in my family/great room.  I also just bought a used set of Klipsch RF-15 speakers - they are an older version of the RF-52s.  They only have 5.25" drivers, so they lack bass, and I need a subwoofer to add some punch to my music/movies.

 

I currently have a Klipsch subwoofr that is very old, that i had when I was much younger. It is from the mid 1990s.. it is a model called SW-8.  It has a 65W amp, an 8" driver on the front, and a 10" passive radiator on the back.  It still works fine.  

 

I am in the process of getting a center speaker and rear surrounds to hook up - I have some small/cheap speakers I can use until I can afford higher quality units, but I just haven't wired them up yet... 

 

As to my sub - I think that what I have is decent..but not substantial enough for the music I like.  My sub makes decent bass for some music, but when the bass gets really deep, it doesn't seem to have that deep "boom" that you can hear/feel.  Say I put on some rap CD, or some current bass heavy song - my sub doesn't seem to go that low and isnt' loud enouhg.

 

I also notice that the bass is more pronounced in some parts of the room, and almost non-existent in other parts of the room.  My room is kind of big - 20x20 feet almost.. it's a big big room thas has family room/dining/kitchen all in one.. 9' ceilings.  

 

I was at Fry's to buy my receiver and I went into the subwoofer demo room and they had a Klipsch SW-115 hooked up.. it was like $900 give or take.. expensive.  That thing boomed - it was really nice.  you could literally feel it in your chest.  I'm NOT goign to spend $900 on a sub... I'd like to..but it's not gonna happen.  ;)  

 

I'm looking at used stuff on CL... I don't have to buy a Klipsch unit, but I would like to.  I have seen several used Klipsch subs for sale in the $100-200 range.  some are 8" , some are 10", and a few are 12s.  

 

I"ve seen the following models, SW-12, KSW-10, and other 10" or 12" subs.

 

I am going to the store to demo some of these more affordable subs, but I'm wondering if anyone can offer any suggestions as to whether they have any knowledte of the sub that I am currenlty using, the SW8, and have any opnion as to how much better even these entrylevel modern subs would be by comparison.

 

I'm wondering if a relatively newer 10" or 12" sub would produce substantially more bass and deeper bass than what I have now.

 

another quesion is if I were to buy another larger sub - would it be possibl eto run BOTH subs together to get more bass?  woudl my entry level Y amaha receiver be able to do that or do I need more advanced elecronics or something to run two subs?

 

thanks.

First of all, forget the Klipsch subs, you can do better whatever your budget is. But what is your budget? You can't spend $900 but can you swing $500?

Honestly, I'd like to spend $150-200 on the used market... Which means I'm more likely to find mass producers consumer grade items vs higher end it audiophile equiemt.. I'm guessing stuff thst cost $350-500 new can eventually be found on CL or eBay or other used site or $150-200ish.

I also am saving up for a center.

Can I use two subs? My SW-8 isn't bad.. For some audio tracks it sounds great but some
Deeper stuff it seems like it has a hard time.. If it is easy to run two subs I'll upgrade and run them both.. Unless that is not as easy as I assume t is...

I think it would be hard to beat this for under $200, and should put a whupping on your old sub by a long shot.

 

As far as a center channel on a budget, how about the Andrew Jones piece:

1) do a "sub crawl" if you haven't yet
2) yes, it's hard to integrate two different subs
3) two dayton sub-1200 would be great and they're $109/each when on sale.

Fixed :)

 

Even with an inexpensive Dayton sub I think you will be surprised how much the 8" is lacking.

Is it easy to integrate two of the same subs? Like if I bought two if the exact same
One? The. It can be done? Can I do it with the entry level Yamaha receiver I have?

$109 seems REALLY cheap for a 12" sub!! for that price i could buy two... how hard is that to integrate?  how do you actually do it?  do they run in daisy chain fashion? or do you have to splice the sub signal?  

 

thanks!

 

as for a center channel.... since i have the Klipsch RF-15, I was thinking of doing an RC-52 or RC-62 center once I find a good deal on a used one.

Just takes a Y splitter and three subwoofer cables of the correct length.

1) sub crawl
2) Two of the same isn't hard, but not as simple as one. Your AVR has YPAO - which should help with the set up. You just need a Y-splitter like 'Bear' said. LINK
3) Dayton Sub-1200 Review. The person who wrote that also posts on here. Check the budget sub thread for more info.

If you really want to learn more you should check out the Home Theater Geeks podcast. They're very informative.

do you think I'd be better off with one 15" or two 12"s?

 

it would be almost the same price... slightly more expensive for two 12" subs... but not much.  i'm sure my wife wouldn't like TWO subs "messing up" her furniture and having to be placed in less than ideal places on the carpet... but if it would sound substantially better..i'd be game to try it.

 

I am hoping that one 15" would work...  my current 8" has a supris9ing amount of bass.... i was listening to a track tonight and when I was about 8' in front of it, and off to the side.. it boomed like crazy... amazing bass.. then I walked 10' in the other direction and you almost couldn't even hear the bass at all.. literally.

 

thanks!!

Best argument for dual subs, and you realized it first hand.  Duals with smooth response throughout the room.   My vote would be dual 12's if that is all the budget allows, or get one 15" now, and another as soon as you have another $180.
