Splash Into a Summer of Sound

Whether you dock your boat at a lakeside marina or a spot right off the ocean, your vessel is a getaway from the everyday. But what's an escape without a summer theme song? Belva's MS Series Marine Speakers maximize your offshore adventures by letting you hear your song the way it was meant to be heard.

With the high performing balanced dome tweeters and single-piece polymer basket, the BBMS65 speakers are built not only to jam, but to last.

Belva builds these speakers to sound great across the product line, rather than tuning for one speaker and calling it a day. That way, each speaker sounds perfect, just like your next day on the water.

These full-range marine speakers are weather resistant and ready to put up with the elements. So whether the weather's cooperating or not, it'll never rain on your party. Everything is good to go for sun and salt exposure, and water spray won't dampen your tunes. Hit "Add to Cart" and make this summer the best yet!

Awesome speakers for the money

The following review is for BBMS65W, which is a part of the bundle you are viewing.

These speakers sound amazing for $50 I'd recommend these ... They sound 100 percent better in an enclosure I mounted them into 6" tubes sounds great.

Do not buy!!

The following review is for MSA4‐1300D, which is a part of the bundle you are viewing.

Bought this amp and after about 15 minutes of playing the right front channel went out. So I contacted Sonic Electronix where I purchase this amp and they are out of stock! The best part is they do not know when they will get more in stock. Do yourself a favor and do not buy this product!!!

Excelent Help and Service

The following review is for BBMS65W, which is a part of the bundle you are viewing.

Great customer service and products. Ordered one set of speakers but noticed they didn't ship the next day so I called and found out they had to drop ship. I canceled the order and ordered different speakers with no issue. Second set showed up quickly but I didn't need. Requested RMA with no issue. Purchased shipping through Sonic with no issue. Returned them. Great information and service and I will be using them again and referring others to do the same.
