Clean bass? yes, please!
I initially wanted the sub right next to my chair so that I could use it as a table. It turned out to not be the most ideal location for it. I slid a matt underneath and pushed it around to different locations in the room and has now found its final resting place and it sounds sublime!
This driver can reproduce bass line textures as precisely and articulately as possible without being lost in the mix of other lower frequencies. The bass drum kick is realistic and pronounced with the correct amount of weight and minimal decay. I'm not much of a bass-head, but I can appreciate how a good bass rendition may elevate the listening experience. The crossover began at 200hz and has now settled at 85hz.
This driver's LF reproduction is not intrusive or overbearing in any way; rather, it gently fills the room and pressurises it when necessary so that you can "feel" the bass. My typical listening volumes do not exceed 70-75db, and yet, the bass is renditioned beautifully.
I have two 12" Rythmiks, and I thought they were excellent at what they did before I heard what a single 15" driver could deliver!
Beginnings.
I was on a hunt for a subwoofer that would complement my bookshelves in the smaller room. Going by the prevailing prices of branded subwoofers, I reckoned I could have one built for a lesser price and perhaps of better quality.
Going into this project my brief was simple; i.e. good quality bass in a sealed box with a 15" driver. I didn't care for high SPL. I wanted someone to take up this project for me, as I have never built a speaker box before.
When there were no takers, I decided to go forth and cut the wood myself. All I had for this build was a marble cutter, an angle grinder and a drill machine.
But I never would have ventured into this build blind. The enthusiasm and attention of
@Vineethkumar01 were enough to spur me on to forge ahead. I genuinely appreciate and thank him for his ongoing advice. Thanks to my local audio enthusiast and buddy
@ssf for loaning me his Crown XLS to power the sub.
@keith_correa , and everyone else who contributed.
The build has gotten my juices flowing. Not simply because it was satisfying and successful, but also because I have a renewed appreciation for DIY audio. Terrific value is on offer in building tried and tested speaker designs, and at a reasonable price; Kairos by Jeff Bagby, perhaps? I know that
@Prodigy owns these, and I hope I have an opportunity to listen to these next.
Here's the cost breakup for the keen.
