Hey Everybody!
I am looking to buy a subwoofer that will be used in my bedroom for a home theater application. I plan on using the base of my waterbed as an enclosure (try to make use of some of that wasted space) so there isn't much of a size restriction. To power the sub, I have a 250 watt Class AB Amp from PartsExpress. A few drivers that have been recommended to me so far are:
DAYTON RSS315HF-4 12" HIGH FIDELITY SUBWOOFER
DAYTON ***320C-4 12" TITANIC MKIII SUBWOOFER
PEERLESS 830500 XLS 12" SUBWOOFER
Adire Audio Shiva 12D8
I would like to keep the price around the range of those listed above. Other than that I am open to just about any suggestions!
I have a Sony STR-DB930 receiver and my main L/R are a pair of JBL Studio Monitor 4410.
Thanks for your help!

Hi,
there was a crude joke in that earlier thread. Something to do with bed bases and bass drivers.
But I do endorse the horn idea. |

| Right now the height is only 10" but I plan on rebuilding it so that I can put the sub and hopefully some cabinet space under there... I am not familiar with horns at all, so I am looking forward to a fun project/learning experience here... |

Hi,
If you want an idea what to expect have a search for bed base? and horn or bass speaker.
There were a couple of threads about/a liitle more than, a year ago. |

| If you think it's a too big project, don't worry. A typical ported or sealed box will work well too, for a learning experience, and sonically. |

Alright so i've been doing some research on this horn business... I have built sealed and vented sub boxes before and I think I could handle building a horn enclosure, however, I don't think I know quite enough to do all the designing myself. Something like this http://diy.cowanaudio.com/hornsub.html looks very appealing to me and I should have enough room for it as a bed base. I would plan on using the Eminence Omega Pro 18 driver (to save some money). My concerns are:
1. I only have a 250 watt amp... I know these designs are efficient, but will this be enough power?
2. If 250w isn't enough for the 18, would it be ok for a 12" or 15" driver?
3. I've read that horn designs don't scale well... Would it be practical to even use a 12" or 15" driver or would I be better off just building a sealed or vented box?
Thanks for looking!

Hi,
based on Tom Danley's info, his horn produced the same SPL (volume) as (from memory) 5times as many vented boxes driven with 10times as much power.
On that basis your 250W will sound more like 2.5kW.
My opinion, if it's worth anything; 250W is more than enough for ANY domestic situation.
The longer you make the flare rate the lower it will go and the less likely it will unload as the horn reaches it's low limit.
I, somewhat jokingly, said in another thread he should buy an ipod to drive his bass horn. |

| I recommend a sub in a separate enclosure, subwoofer placement can be critical, if its in the wrong place you might not hear any bass at all at the listening position. |
